Delete Cursor (must Change It !!!!)

Feb 3, 2005

Hi all,

The db that I took over is full of !@##$@, unnormalized tables, cursors, you name it and it has it :(.

There is this cursor that opens a temp table, fetches the key and then deletes from the production table using that key for every row in the temp table.

I want to change it to something like

delete from A
where exists (select 1
from B
where B.ID1 = A.ID1 and
B.ID2 = A.ID2)

Now, I'm thinking that this query would secuentially scan A and compare the key to what B has and that is a waste of time. Is there a way to do it the other way around ? Scan the rows on table B and then delete them from table A ?

I haven't really played with sql in some time, maybe the answer is trivial but I can't see it right now.

Thanks in advance

Cannot Change DB Context In Cursor

Jun 18, 2006

Hi There

I am trying to loop through databases to gather information.

However if i loop though datbases in a cursor, by using a select from sysdatabases, once i am in the cursor and SET @Sql = 'use ' + DBName and EXEC(SQL), the database context never changes from the one the cursor is executing in.

Is there a way to loop through database contexts and execute sql ?

Thanx

SQL Server 2012 :: Change Database Within A Cursor?

Aug 21, 2015

I like to backup the stored procedures' code used in my databases. So I created this Script:

/*
IF OBJECT_ID('[Monitor].[dbo].[Procedurecode]') IS NOT NULL DROP TABLE [Monitor].[dbo].[Procedurecode];
*/
DECLARE
@db nvarchar(50),
@strSQL nvarchar (100)
IF CURSOR_STATUS('global','cur1')>=-1 BEGIN DEALLOCATE cur1 END

[code]....

Problem is (and I seem not to be the only one with tis) described here:

"If the executed string contains a USE statement that changes the database context, the change to the database context only lasts until sp_executesql or the EXECUTE statement has finished running." There is nothing magical in SQL server that knows you intend a series of dynamic sql commands to be part of a single job running in a single context. You have to build the entire string for the job you want to execute."

[URL]

So I only get the SPs of the current database.

Gridview Delete Behavior Change From Beta2 In VWD Express

Nov 12, 2005

I've not been able to test this yet in full VS2005 (MS is screwed up with orders for some reason. Has anyone heard this one. All orders for less than quantity=5 were being rejected). So, instead of waiting for it I installed VWD Express. Now, the project had been built in VWD express beta 2, so no big change there.Several gridview controls in the project had <Delete> enabled. Just <Delete> mind you. Nothing else for command buttons. They all worked fine with delete queries that use gridview.selectedvalue as the parameter. Every single one stopped working since I've converted from beta 2 to RTM!Here's what I determined. The delete will only work if the row in the grid is selected first!. Otherwise <selectedvalue> is null when you click on <Delete>.Is this a bug or what?I'd be happy to supply more details. I am certain others will report this, but I have yet to find a post here or in any blogs out there that reproduce this problem in the RTM of .NET 2.0

Transact SQL :: STATIC Defines A Cursor That Makes Temporary Copy Of Data To Be Used By Cursor

Aug 12, 2015

In MSDN file I read about static cursor

STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications

It say's that modifications is not allowed in the static cursor. I have a  questions regarding that

Static Cursor
declare ll cursor global static
            for select  name, salary from ag
  open ll
             fetch from ll
 
              while @@FETCH_STATUS=0
               fetch from ll
                update ag set salary=200 where 1=1
 
   close ll
deallocate ll

In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says  modifications is not allowed in the static cursor.But I am able to update the data using static cursor.

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance

Jul 20, 2005

Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

Master Data Services :: Hard Delete All Soft Delete Records (members) In Database

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.

Copy And Delete Table With Foreign Key References(...,...) On Delete Cascade?

Oct 23, 2004

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!
Sky

SQL - Cascading Delete, Or Delete Trigger, Maintaining Referential Integrity - PLEASE HELP ME!!!

Nov 13, 2006

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

Delete Syntax To Delete A Record From One Table If A Matching Value Isn't Found In Another

Nov 17, 2006

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

Feb 16, 2008

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)

Allow Single Row Delete From A Table But Not Bulk Delete

Sep 16, 2013

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.

Delete Doesn't Delete Rows, But @@ROWCOUNT Says It Did

Aug 20, 2007

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?

Cannot Amend Or Delete Subscription And Cannot Delete Report.

Nov 20, 2007



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

DB Engine :: Collation Change And DDL Change In Same Script

Nov 18, 2015

We ran into weird/interesting issue with below details.

Version: Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64) Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200):

We are using SQLCMD to run DDL script on our product database in below order. That script has below content.

step # 1 - database collation change (case -sensitive) statement as very first statement of the script
step # 2 - Actual DDL SQL statements
step # 3 - database collation change back to original (case insensitive)

When we execute all above 3 steps in single script using SQLCMD on our test_server#1 , it is successful but when same is being implemented on test_ server#2 , it is failing.We ensured that there is no other user accessing the db and setting on both the server are all default/basic. Separating out all 3 steps in 3 different script working fine. This is only problem when we combine them into single script and fire it using SQLCMD. If it is something related to session/transaction then we should hit same issue on our test_server#1 server as well but that is not the case.test_server#1 and test_server#2 has exact same database/data, just two different physical machine & SQL Server instance.

Delete From Vs Delete With Subquery In Transaction

Feb 23, 2006

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.

To Delete Or Not To Delete - DESIGN ISSUE!

Apr 3, 2008

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!

Soft Delete In Table, Why Merge Agent Report Hards Delete On Table ?

Feb 1, 2007

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

Ahmad Drshen
