Delete Merge Filter
Feb 9, 2006
I am currently running sql 2000 with 2 way merge replication... I have a problem of I need to delete about 3 million rows from a table that is constantly being accessed buy an e-commerce site. I have thought about setting up a filter to only replicate new or altered rows beyond a a certain indexed number... then delete from both sites the unneeded rows... this should work.. but can I delete the filter after I am done??
If this is not an option, any other suggestions?? I cannot take either site offline and I cannot do anything that will take more than a few seconds to replicate... by deleting these rows. my table size will be reduced by almost 8GB...
thanks

Brand new to SQL Server 2005 and replication, I was able to use online books info to get a replication topology set up (using wizards) and successfully replicate an article (a single table) to a SQL Server Express database.
I then cleared the subscription table and added a simple dynamic filter (colx = SUSER_SNAME()), which I can't get to work. Based on what I read, I'm thinking that SUSER_SNAME() is not returning the proper value because the merge agent is set to connect to the publisher and distributor by 'impersonating the process account'. This is on the subscription merge agent security form. However, 'using a SQL Server login' is greyed out and nothing I tried will enable it, including setting up logins and SQL user ids on the publisher and playing with entries on the publication properties data partitions page, etc.
I think that I have discovered only some of the pieces that I need and not enough details to find the rest and put them together. Any info on what to have set up where would be appreciated. Any suggestions for 'step by step' information that would help in addition to SQL Server 2005 Books Online would be great.
Thanks in advance.

Hi!
I'm a merge newbie and have a couple of questions. I'm about to setup a merge replication with Sql Server 2005 and Sql Server CE as a subscriber. Situation is like this, we have 10 service technicians using pda.
I want to each pda user have their own data. What I understand I need to use dynamic filter and SUSER_NAME()?? Do I need to create a "translation" table to map my system's UserId against SUSER_NAME? How have you solved this problem?

Hi ...
I am working on a project where the server version of application has vouchers from different entities. I have created a publication manually. My next step was to create a client subscription using rmo and to execute a pull. This part works fine. Code samples from http://msdn2.microsoft.com/en-us/library/ms147314.aspx
My next step would be to implement dynamic filtering using the guid of the entity as a parameter.
I dont want to use suser_sname() or host_name() as I want to use a fixed login for the replication for all users, and a client could have several host dbs (sql express, sql mobile)
My goal would be to pass a guid-value to the HostName Property of the MergePullSubscription class and convert it to an uniquidentifier and use it as a filter as I have not found any other way to pass a guid as a filter.
RMO-Code:
subscription.HostName = "4bb0e468-c68a-4253-ba82-f71c3a6e302d"
Filter:
SELECT <published_columns> FROM [dbo].[voucher] WHERE [entity_ID] = dbo.fx_ConvertHostToEntity()
Function:
create function fx_ConvertHostToEntity()
returns uniqueidentifier
as
Begin
declare @host nvarchar(50)
set @host = host_name()
declare @entity uniqueidentifier
set @entity = cast( @host as uniqueidentifier)
return @entity
End
When trying to set the filter sql server complains that a character string cannot be casted to a uniqueidentifier - so i can not set this filter. Is there a way to pass a parameter other then the username or the hostname as a filter?
SELECT <published_columns> FROM [dbo].[voucher] WHERE [entity_ID] =@entity, where @entity is a guid
Thanks for your support

Hi,
I have a merge (SQL 2005 Standard -> Express) topolgoy which is having problems
The main problem is that the join filters don't seem to work for one area and I am hoping someone can help me with some troubleshooting advice
There are 140+ tables in the topology but the ones causing particular pain are a parent child relationship where the child is actually a bridge/linking table to another table.
Therefore although it is a parent child in the replication filters it is the reverse. i.e. the child has the paramterised filter on it and the parent is one level down joined by it's id. There are other tables joined to this parent table but it stays at three levels deep. The @join_unique_key therefore is set to 0 as is the partition options for the parent /child relationship.
However, when we synchronise we have a problem. The rows get inserted in to the database in RI order but only the child records are replicated down to the subscriber.
The child table with the parameterised filter has 13 articles joined to it in total and one of the other branches of join filters go down as deep as four levels. Most though do not.
Does anyone have any suggestions as to why this might be happening? Any help would be greatly appreciated.
Cheers, James
P.S. I should add this problem only occurs when the edits are made at the publisher. If new records are added at the subscriber everything is fine.

We have a table in an SQL Server 2012 database that stores tree-like structures. Simplified for the purpose of my question, it has the following format:
Id int identity,
ParentId int,
GroupId int
Each record of the table represents an object identified by Id. An object may or may not have a parent in the same table, such that object.ParentId = parentObject.Id. A root object has ParentId = NULL. There are multiple root objects, so the table in fact stores multiple trees. What’s important is that the tree depth is not fixed, i.e. theoretically there can be any number of ancestor generations for an object. GroupId is a property of a root object; in theory none of the children of a root object has to have GroupId <> NULL; it can be assumed that any child has the same GroupId value as its root object.
A sample table having two roots (one grandparent and one parent), one non-root parent/child and 4 child roots:
Id ParentId GroupId
----------------------------------------------------------
1 NULL 200 root grandparent
2 1 NULL non-root parent/child
3 2 NULL child
4 2 NULL child
5 NULL 300 root parent
6 5 NULL child
7 5 NULL child
The table is not normalised, i.e. there’s no separate {root_object : group} table. However I don’t think normalising the table would solve the problem.
Now the problem. We need to set up merge replication from the table above (Master table) to the table of the same format in another DB. We need to replicate only those rows of the Master table that have a certain fixed GroupId value, e.g. 200 in the example above. If we ensure that GroupId in all descendant objects of a root object has the same value in the table as the root object itself that would be trivial. The table would look like this:
Id ParentId GroupId
----------------------------------------------------------
1 NULL 200 root grandparent
2 1 200 non-root parent/child
3 2 200 child
4 2 200 child
5 NULL 300 root parent
6 5 300 child
7 5 300 child
And the filter would look like this:
WHERE GroupId = 200
However out of performance considerations, we would like to avoid if possible filling GroupId for the descendant objects, because as it must be clear from the above, GroupId for a descendant object is quite easily deducible via a stored procedure or UDF (just need to go up the tree until ParentId = NULL). The problem is, I don’t know how to achieve this in a merge replication filter: it would only allow WHERE conditions and joins. I’ve have not had much luck with joins for merge replication in general, but here we have more complex algorithm, because the number of tree levels can be different for every object. And merge replication would not allow using UDF…

Hi seniors
there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.
regards

I have a table:
declare tableName table
(
uniqueid int identity(1,1),
id int,
starttime datetime2(0),
endtime datetime2(0),
parameter int
)
A stored procedure has new set of values for a given id. Sometimes the startime and endtime are the same, in which case I update the value of parameter. Sometimes I add a new time range (insert statement), and sometimes I delete a time range (delete statement).
I had a question on merge, with insert, delete and update and I got that resolved. However I have a different question regarding performance of the merge statement.
If my target table has hundreds of millions of records and I want to delete/update/insert a handful of records, will SQL server scan the entire target table? I can't have:
merge ( select * from tableName where id = 10 ) as target
using ...
and I can't have:
merge tableName as target
using [my query] as source on
source.id = target.id and
source.starttime = target.startime and
source.endtime = target.endtime
where target.id = 10
...
This means I cannot filter the set of rows in the target table to a handful of records where id = 10.

I'm not even sure this is possible but I'm using MERGE in a process that has 3 source tables (the process steps through each source table sequentially) and I need to delete from the Target database occasionally.
My current code is
sqlMerge = "MERGE " + TableName + " AS target USING @CData AS source" +
" ON target.TotRsp = source.TotRsp AND target.ClientRef = source.ClientRef AND target.dbPatID = source.dbPatID" +
" WHEN MATCHED THEN" +
" UPDATE SET dbPatFirstName = source.dbPatFirstName, dbPatLastName = source.dbPatLastName,
[Code] ....
The Target db data is made up from several different clients and when the MERGE runs it uses TotRsp, ClientRef and dbPatID to uniquely match a source row to the target row and if no match it inserts the source row.
My problem is that when this runs with Source A first, it will delete all merged data from Source B & C. Then when Source B runs it will insert all Source B data but delete all from A & C and so on.
Is there way that that I can include additional clauses into NOT MATCHED BY SOURCE THEN so it knows only to delete when data has come from say Source A. Once the data is in the target table there is no reference to which source table it came from tho.
If there isn't a solution I suppose I could always add an extra column to the target db to indicate which source it came from and then have something like
NOT MATCHED BY SOURCE AND t.Source = 'SourceA'.
That's quite a bit of work my end to do that tho so I'd like to be sure it works.

If anyone could confirm...
SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.
E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.
First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.
However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.
Question: I thought the filters would remain dynamic and be applied on each sync?
I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!
Question: I wonder why if parent records are supplied, why not child records?
If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...
Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

I have created a Dynamic Merge statement SCD2 Store procedure , which insert the records if no matches and if bbxkey matches from source table to destination table thne it updates old record as lateteverion 0 and insert new record with latest version 1.
I am getting below error when I ahve more than 1 bbxkey in my source table. How can I ignore this.
BBXkey is nothing but I am deriving by combining 2 columns.
Msg 8672, Level 16, State 1, Line 6
The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source rows.

Hello,
Here is my problem:
I use SQL Server 2005. I have approx. 50 tables in my database and 30 of them have a filed named "CompanyID". Example:
create table A (ID int identity, NAME varchar(100), COMPANYID int)create table A (ID int identity, REF_ID int, FIELD1 varchar(100), FIELD2 varchar(100), COMPANYID int)
Also there are nearly 200 stored procedures that read data from these tables. Example:
create procedure ABCasbegin /* some checks and expressions here ... */ select ... from A inner join B on (A.ID = B.REF_ID) where ... /* ... */end;
All my queries in the Stored procedure does not filter the tables by CompanyID, so they process the entire data.
However, now we have a requirement to separate the data for each company. That means that we have to put a filter by CompanyID to each of those 20 tables in each query where the tables appear.
Firstly, I put the CompanyID in the context so now its value is accessible through the context_info() function. Thus I do not need now to pass it as a parameter to the stored procedures.
However, I don't know what is the easiest and fastest way to filter the tables. Example:
I modified the above mentioned procedure in the following way:
create procedure ABCasbegin /* some checks and expressions here ... */
-- gets the CompanyID from the context: DECLARE @CompanyID int; SELECT @CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))
select ... from A inner join B on (A.ID = B.REF_ID) where ...
and A.COMPANYID = @CompanyID and B.COMPANYID = @CompanyID /* ... */end;
Now I have the desired filter by CompanyID. However, modifying over 200 stored procedures is rather tedious work and I don't think that this is the best approach. Is there any functionality in SQL Server that can provide the possibility to put an automatic filter to the tables.
For example: when I wrote "SELECT * FROM A", the actual statements to be executed would be "SELECT * FROM A WHERE CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))".
I was looking for something like "INSTEAD OF SELECT" triggers but I didn't manage to find any answer.
I would very grateful is someone suggests a solution for something like "global table filter" (that will help me make an easy refactoring)?
Thanks in advance.
Best regards,
Beroetz

Howdy,
I have a table that has a group. In this group, I want to filter by 2 different expressions, concatenated with an OR. BUT I can't change the "And/Or" column value for the first entry because it is grayed out. The column will automatically change to an OR value if both my expression column fields are the same (which I don€™t want) but if I put any other value in to the expression field of the second row, the "And/Or" field of the first row automatically changes to an AND.
PLEASE! How do I get the And/Or field "ungrayed" so I can change it to what I want?
The 2 filters I and using check the UserID = to the user, and the other is checking a count to get the Top N 1. (So just showing the current user and the top producer)

I have database on SQL Server 2000 set up with a merge publication.This publication is configured with a number of dynamic filters toreduce the amount of data sent to each client. Each client has ananonymous pull subscription. The merge process can be triggered by thewindows sync manager and my application.To improve performance I have created some helper tables to hold themapping between user login and primary keys of selected entities.For the replicated data to be correct the contents of the helper tablesneeds to be up to date.I need to fire off a stored procedure on the publisher beforereplication starts to verify that this data is up to date. I can notsee any documented way of doing this however I have been experimentingwith some unorthodox systems.Firstly has anyone any ideas?I have been considering adding a trigger to some of the tables used bythe Microsoft replication code - yes I know this is very nasty.My problems arise because executing this stored procedure will causesome data to be updated. In updating data we could create a newgeneration in the database. I must therefore run my stored procedurebefore any the Microsoft code makes any generation checks / updates.Anyone done anything similar, Anyone have any better ideas?Any comments would be gratefully received.

Hi,
I'm using merge replication to maintain a backup copy of my main (publisher)MSDE database. A push subscription periodically (1 per minute) updates the backup DB.
It's intended that if the main db goes down then the backup (subscription) db can be configured as a publisher. This must all be performed via scripting.
The initial configuration of the main publisher and subscription is controlled via scripting, which works fine.
The problems occur when I try to configure the subsciber to become a publisher. A script is executed on the subscriber but fails at the point when it's configuring the publisher detail. The error is something like "unable to configure a publication for a database setup as an anonymous subscription".
I'm guessing that there are subscritpion artifacts added to the database which need to be removed before it can be configured as a new publisher.
Please help,
Jez W

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

Hello:
Need some serious help with this one...
Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?
The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
Thanks!

I am having great difficulty with cascading deletes, delete triggers and referential integrity.
The database is in First Normal Form.
I have some tables that are child tables with two foreign keyes to two different parent tables, for example:
Table A
/
Table B Table C
/
Table D
So if I try to turn on cascading deletes for A/B, A/C, B/D and C/D relationships, I get an error that I cannot have cascading delete because it would create multiple cascade paths. I do understand why this is happening. If I delete a row in Table A, I want it to delete child rows in Table B and table C, and then child rows in table D as well. But if I delete a row in Table C, I want it to delete child rows in Table D, and if I delete a row in Table B, I want it to also delete child rows in Table D.
SQL sees this as cyclical, because if I delete a row in table A, both table B and table C would try to delete their child rows in table D.
Ok, so I thought, no biggie, I'll just use delete triggers. So I created delete triggers that will delete child rows in table B and table C when deleting a row in table A. Then I created triggers in both Table B and Table C that would delete child rows in Table D.
When I try to delete a row in table A, B or C, I get the error "Delete Statement Conflicted with COLUMN REFERENCE". This does not make sense to me, can anyone explain? I have a trigger in place that should be deleting the child rows before it attempts to delete the parent row...isn't that the whole point of delete triggers?????
This is an example of my delete trigger:
CREATE TRIGGER [DeleteA] ON A
FOR DELETE
AS
Delete from B where MeetingID = ID;
Delete from C where MeetingID = ID;
And then Table B and C both have delete triggers to delete child rows in table D. But it never gets to that point, none of the triggers execute because the above error happens first.
So if I then go into the relationships, and deselect the option for "Enforce relationship for INSERTs and UPDATEs" these triggers all work just fine. Only problem is that now I have no referential integrity and I can simply create unrestrained child rows that do not reference actual foreign keys in the parent table.
So the question is, how do I maintain referential integrity and also have the database delete child rows, keeping in mind that the cascading deletes will not work because of the multiple cascade paths (which are certainly required).
Hope this makes sense...
Thanks,
Josh

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
DELETE FROM Broker_Rates
WHERE (Broker_Rates.BID <> Broker.BID)
Thanks

I'm using SqlDataSource and an Access database. Let's say I got two tables:user: userID, usernamemessage: userID, messagetextLet's say a user can register on my website, and leave several messages there. I have an admin page where I can select a user and delete all of his messages just by clicking one button.What would be the best (and easiest) way to make this?Here's my suggestion:I have made a "delete query" (with userID as parameter) in MS Access. It deletes all messages of a user when I type in the userID and click ok.Would it be possible to do this on my ASP.net page? If yes, what would the script look like?(yes, it is a newbie question)

The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS
[code]...
When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.

I ran the following query in Query Analyzer on a machine running SQL Server 2000. I'm attempting to delete from a linked server running SQL Server 2005:
DELETE FROM sql2005.production.dbo.products
WHERE vendor='Foo'
AND productId NOT IN
(
SELECT productId FROM sql2000.staging.dbo.fooProductList
)
The status message (and @@ROWCOUNT) told me 8 rows were affected, but nothing was actually deleted; when I ran a SELECT with the same criteria as the DELETE, all 8 rows are still there. So, once more I tried the DELETE command. This time it told me 7 rows were affected; when I ran the SELECT again, 5 of the rows were still there. Finally, after running this exact same DELETE query 5 times, I was able to remove all 8 rows. Each time it would tell me that a different number of rows had been deleted, and in no case was that number accurate.
I've never seen anything like this before. Neither of the tables involved were undergoing any other changes. There's no replication going on, or anything else that should introduce any delays. And I run queries like this all day, involving every thinkable combination of 2000 and 2005 servers, that don't give me any trouble.
Does anyone have suggestions on what might cause this sort of behavior?

Hi,
I have a problem with one report on my server. A user has requested that I exclude him from receiving a timed email subscription to several reports. I was able to amend all the subscriptions except one. When I try to remove his email address from the subscription I receive this error:
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
For more information about this error navigate to the report server on the local server machine, or enable remote errors
Online no help couldn't offer any advice at all, so I thought I'd just delete the subscription and recreate it again, but I receive the same message. "Okay, no problem, I'll just delete the report and redeploy it and set up the subscription so all the other users aren't affected", says I. "Oh, no!", says the report server, and then it give me this message:
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Data.SqlClient.SqlException: Only members of sysadmin role are allowed to update or delete jobs owned by a different login. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.InstrumentedSqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.DBInterface.DeleteObject(String objectName) at Microsoft.ReportingServices.Library.RSService._DeleteItem(String item) at Microsoft.ReportingServices.Library.RSService.ExecuteBatch(Guid batchId) at Microsoft.ReportingServices.WebServer.ReportingService2005.ExecuteBatch() --- End of inner exception stack trace ---
What's even weirder is that I'm the owner and creator of the report and I'm a system admin and content manager on the report server and I set up the subscription when the report was initially deployed. Surely I should have sufficient rights to fart around with this subscription/report as I see fit?
I have rebooted the server, redeployed the report, checked credentials on the data source and tried amending and deleting from both the report manager and management studio but still I am prevented from doing so.
Any help would be much appreciated.
Thanks in advance,
Paul

First, this is not my code.
This one is weird and I am missing something fundamental on this one. A developer was getting a timeout with this...
CREATE PROCEDURE p_CM_DeleteBatch
(
@SubmitterTranID VARCHAR(50)
)
AS
DECLARE
@COUNT INT,
@COMMIT INT
SET @COUNT = 0
SET @COMMIT = 1 --DO NOT CHANGE THIS. The Operation will be commited only when this value is 1
select @COUNT = COUNT(*) from claimsreceived
where (claimstatus NOT IN ('Keyed', 'Imported')) AND
SubmitterTranID = @SubmitterTranID
IF (@COUNT = 0) --This means that that Claims under this Batch have not been adjudicated & it is safe to delete
BEGIN
BEGIN TRANSACTION
DELETE FROM INVOICECLAIMMAPPING WHERE CLMRECDID IN (SELECT DISTINCT CLMRECDID FROM CLAIMSRECEIVED WHERE SUBMITTERTRANID = @SUBMITTERTRANID)
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsPayment WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsPaymentServices WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsreceivedPayorServices where ClmRecdPyID in (SELECT ClmRecdPyID
FROM ClaimsReceivedPayors
WHERE SubmitterTranID = @SubmitterTranID)
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsReceivedPayors WHERE ClmRecdid in (SELECT ClmRecdID
FROM ClaimsReceived
WHERE SubmitterTranID = @SubmitterTranID)
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsReceivedServices WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsReceived WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM BATCHLOGCLAIMS WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
IF (@COMMIT = 1)
BEGIN
--ROLLBACK TRANSACTION --For Testing Purpose ONLY
COMMIT TRANSACTION
RETURN (0)
END
ELSE
BEGIN
ROLLBACK TRANSACTION
RETURN (-1)
END
END
ELSE
BEGIN
RaisError ('This Batch cannot be deleted. It has claim(s) which has been Adjudicated', 16, 1)
END
GO
I applied a couple of indices and got ride of the uncorrelated subqueries
CREATE PROCEDURE p_CM_DeleteBatch
(
@SubmitterTranID VARCHAR(50)
)
AS
DECLARE
@COUNT INT,
@COMMIT INT
SET @COUNT = 0
SET @COMMIT = 1 --DO NOT CHANGE THIS. The Operation will be commited only when this value is 1
select @COUNT = COUNT(*) from claimsreceived
where (claimstatus NOT IN ('Keyed', 'Imported')) AND
SubmitterTranID = @SubmitterTranID
IF (@COUNT = 0) --This means that that Claims under this Batch have not been adjudicated & it is safe to delete
BEGIN
BEGIN TRANSACTION
DELETE INVOICECLAIMMAPPING
FROM INVOICECLAIMMAPPING
JOIN CLAIMSRECEIVED
ON INVOICECLAIMMAPPING.CLMRECDID = CLAIMSRECEIVED.CLMRECDID
WHERE CLAIMSRECEIVED.SUBMITTERTRANID = @SUBMITTERTRANID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsPayment
WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsPaymentServices WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE ClaimsreceivedPayorServices
FROM ClaimsreceivedPayorServices
JOIN ClaimsReceivedPayors
ON ClaimsreceivedPayorServices.ClmRecdPyID = ClaimsReceivedPayors.ClmRecPyID
WHERE ClaimsReceivedPayors.SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE ClaimsReceivedPayors
FROM ClaimsReceivedPayors
JOIN ClaimsReceived
ON ClaimsReceivedPayors.ClmRecdid = ClaimsReceived.ClmRecdid
WHERE ClaimsReceived.SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsReceivedServices WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM ClaimsReceived WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
DELETE FROM BATCHLOGCLAIMS WHERE SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)
SET @COMMIT = 0
IF (@COMMIT = 1)
BEGIN
--ROLLBACK TRANSACTION --For Testing Purpose ONLY
COMMIT TRANSACTION
RETURN (0)
END
ELSE
BEGIN
ROLLBACK TRANSACTION
RETURN (-1)
END
END
ELSE
BEGIN
RaisError ('This Batch cannot be deleted. It has claim(s) which has been Adjudicated', 16, 1)
END
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
Suddenly this constraint was being violated with the change
ALTER TABLE [dbo].[ClaimsReceivedPayorServices] ADD CONSTRAINT [FK_ClaimsReceivedPayorServices_CLAIMSRECEIVEDPAYOR S] FOREIGN KEY
(
[ClmRecdPyID]
) REFERENCES [CLAIMSRECEIVEDPAYORS] (
[CLMRECPYID]
)
Is the delete on ClaimsReceivedPayors starting before the delete on ClaimsreceivedPayorServices finishes? If so why would it matter between the join and subquery? This one is making me depressed because I can not explain it.

Hi all
Need some advice solving a little problem I have with my database!
Current setup:
I have a person table that is made up of 39 columns. I also allow for person records to be deleted but I do this by having another table I call LogicallyDeletedrecords. This table is made up of the PersonId, Reason for deletion/suppression and a date time stamp. To access Live records I created a view based on my Person table which contains a WHERE clause to exclude records that exist in the LogicallyDeletedrecords. Similarly, I have another view DeadPersonData which contains Person records that have been removed. Hope it all makes sense so far! Now on to my worries!
The problem:
My Person table contains 9+ million records. The LogicallyDeletedrecords table has 500k+ but I anticipate further growth over the coming weeks/months. My worry is that my LivePersonData view will be too slow to access as my LogicallyDeletedrecords table grows. What’s more, as part of my Load routine, I have to make sure that Person data loaded on to the system is excluded if that same person exists as a deleted member. Both of these actions could slow down my system as the deleted table grows.
My thoughts:
I’ve been thinking of physically deleting dead Person records from my person table (possibly creating an archive table to hold them). But then if I delete them how do I cross check the details when new Person details get loaded?! As I said, my current LogicallyDeletedrecords table holds the PersonId, ReasonDeleted and CreationStamp. The only way is to add further columns which I use to match Person Details?
Any design suggestions would be welcome!
