how can i implement delete constraint? i mean i don't want the rows of the primary key table to be deleted if they are used as foreign key in some other table. so i want to check if that PK is used as foreign key in other tables before deleting.
View 10 RepliesCan somebody tell me about on delete constraint and where should it be used - table having foriegn key?
coz want i want is- the moment i delete the data from the table whose primary key is been referenced as foreign key , The Data in all the tables where its primary key is beeen used as forein key should be deleted.
:confused:
In SQL Server 2005, I hava a client where I do not have access to their SQL Server. I update the database structure by giving them scripts which they run. As I update the structures I occasionally need to delete a constraint, then typically recreate it later. Usually I use this type of snippet:
IF EXISTS (SELECT * FROM sys.default_constraints
WHERE object_id = OBJECT_ID(N'[dbo].[ConstraintName]')
AND parent_object_id = OBJECT_ID(N'[dbo].[tablename]'))
ALTER TABLE [dbo].[tablename] DROP CONSTRAINT [ConstraintName]
This assumes I know the constraint name. A lot of the older constraints have random type names which I assume are different on their server than mine; they were not explicitly given names when created, so they would heve been given names by SQL Server.
Is there a way to delete a constraint without knowing its name? For example, delete all constraints associated with a field, or all constraints ssociated with a table?
Management Studio is an option, but for my client that involves a higher degree of paperwork and permission seeking than just running a script.
Many thanks,

I have a table named [New Item] and created a default constraint on a column, and i wanted to change the data type of the column using the query
alter table [new item]
alter column pcs_qty decimal(15,2) not null
but the name of the default constraint is 'DF__New Item__Pcs_Qt__2D12A970' and i am not able to delete the constraint because it contains a space in between.Is there any work around for this.
I tried to delete the constraint by using the query
alter table [new item]
drop constraint 'DF__New Item__Pcs_Qt__2D12A970'
but I am getting the exception,
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near 'DF__New Item__Pcs_Qt__2D12A970'.

View 1 Replies View RelatedHello All, i have 2 files in excel which i am uploading them to a folder which is located in the root directory. then i am importing these two files into a sqldatabase. i needed some help in importing them and i got it from my previous post at http://forums.asp.net/t/1261155.aspx but now i have a problem. the import works perfectly first time but when i do it the second time i am getting an error on of the file (header). to explain clearly, what i am doing is , every time i upload a new file , i am deleting the data from the tables, so the new data can be inserted ( basically trying to achieve overwirting the existing data). now this technique works fine with the Detail table but not with the Header table. i think the reason is the header table has a primary key on OrderID and a relationship does exists between the Header and Detail. now how would i overcome this error. can some one please guide me.

Hi,
On my aspx Web page, I want to delete a member from database table 'tblMember', but if this MemberID is used as FK in another table, I want to display a user friendlier message like "You cannot delete this member, ....." I am using Try, Catch blocks in my Web Page.
Currently it display this message:
"DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_..._....' The conflict occurred in database '...', table 'tblMembers', column 'MemberID'. The statement has been terminated. "
So how should I precisely trap this error? Does anybody know what Exception is it? or what error number in SQL server?
Thanks
Hi, all.
I am trying to create table with following SQL script:
Code Snippet
create table Projects(
ID smallint identity (0, 1) constraint PK_Projects primary key,
Name nvarchar (255) constraint NN_Prj_Name not null,
Creator nvarchar (255),
CreateDate datetime
);
When I execute this script I get following error message:
Error source: SQL Server Compact ADO.NET Data Provider
Error message: Named Constraint is not supported for this type of constraint. [ Constraint Name = NN_Prj_Name ]
I looked in the SQL Server Books Online and saw following:
CREATE TABLE (SQL Server Compact)
...
< column_constraint > ::= [ CONSTRAINT constraint_name ] { [ NULL | NOT NULL ] | [ PRIMARY KEY | UNIQUE ] | REFERENCES ref_table [ ( ref_column ) ] [ ON DELETE { CASCADE | NO ACTION } ] [ ON UPDATE { CASCADE | NO ACTION } ]
As I understand according to documentation named constraints should be supported, however error message says opposite. I can rephrase SQL script by removing named constraint.
Code Snippet
create table Projects(
ID smallint identity (0, 1) constraint PK_Projects primary key,
Name nvarchar (255) not null,
Creator nvarchar (255),
CreateDate datetime
);
This script executes correctly, however I want named constraints and this does not satisfy me.
We are using SQL CE 3.5 on tablet PCs, that synchs with our host SQL 2005 Server using Microsoft Synchronization Services. On the tablets, when inserting a record, we get the following error:
A duplicate value cannot be inserted into a unique index. [ Table name = refRegTitle,Constraint name = PK_refRegTitle
But the only PK on this table is RegTitleID.
The table structure is:
[RegTitleID] [int] IDENTITY(1,1) NOT NULL,
[RegTitleNumber] [int] NOT NULL,
[RegTitleDescription] [varchar](200) NOT NULL,
[FacilityTypeID] [int] NOT NULL,
[Active] [bit] NOT NULL,
The problem occurs when a Title Number is inserted and a record with that number already exists. There is no unique constraint on Title Number.
Has anyone else experienced this?

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.

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

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,

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

SET @COMMIT = 0
DELETE ClaimsReceivedPayors
FROM ClaimsReceivedPayors

ON ClaimsReceivedPayors.ClmRecdid = ClaimsReceived.ClmRecdid
WHERE ClaimsReceived.SubmitterTranID = @SubmitterTranID
IF (@@ERROR <> 0)

GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON

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!
I am trying to write one sql statement that deletes from two tables. Is it possible ? If yes, any thoughts ?
View 5 Replies View RelatedHi 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.

Hi,
I am trying to figure out how to do this.
For each row, only one out of two columns(id1,id2) should be populated. So if the id1 column is already populated and the application tries to fill in something for id2 then we just simply don't want to allow that and vice versa.
I am thinking triggers is the way to go. What do you think?
thanks

using alter table syntax how can i insert the field TramingChoiceCd
Extend the constraint on NetwkChannel table UQ__TetwkChannel__50FB042B to include TramingChoiceCd
Which is the preferred method Rule, Check Constraint or Trigger?
I want to set a column to todays date when the column is = "T"
else when "F" set it to a future date. Each time there is a insertion into
the table.
I have a varchar field in a table.I want to restrict the entries in that field as "yes" or "no" nothing else.No record will be allowed for this field without yes or no.My question is is it possible without using any trigger for the table?I want to do it with the help of a constraint.
View 1 Replies View RelatedWhen I see desing table option in enterprise manager of a table I don't see any constraints, but when I extract ddl I can see all 6 of them. They are all unique constraints not the check constraints. Is this normal. I am new to SQL Server and would appreciate some explanation.

Hi, i want to put a contraint on a table which much check agains two values in the same column for the same member.
For example, i don't want a male to get information based on breast cancer, and i don't want a female to get information based on prostate cancer.
I have included some sample data. Just copy and paste.
Code Block
DECLARE @MemberLookupValues TABLE (OptionID INT, ValueID INT, Description VARCHAR(20))
INSERT @MemberLookupValues VALUES (3, 10, 'Male')
INSERT @MemberLookupValues VALUES (3, 11, 'Female')
INSERT @MemberLookupValues VALUES (7, 69, 'Prostate Cancer')
INSERT @MemberLookupValues VALUES (7, 70, 'Breast Cancer')
DECLARE @MemberValues TABLE (MemberID INT, OptionID INT, ValueID INT)
INSERT @MemberValues VALUES (1, 3, 10)
INSERT @MemberValues VALUES (1, 7, 69)
INSERT @MemberValues VALUES (1, 7, 70)
INSERT @MemberValues VALUES (2, 3, 11)
INSERT @MemberValues VALUES (2, 7, 69)
SELECT * FROM @MemberLookupValues
SELECT * FROM @MemberValues
I've highlighted the values that must be stopped.
So the basic check would be, IF OptionID = 3 AND ValueID = 10 then it must not allow you to insert the values OptionID = 7 AND ValueID = 70
I hope that makes sense.
Any help will be greatly appreciated, if you need any more informaiton then just ask,
Kind Regards

Hi I was wodering how to add an OR statment right in the Check Constraint expression.
This is what I am starting with in the database
([zip] like '[0-9][0-9][0-9][0-9][0-9]')
and what I want well not exact but this would answer my question
([zip] like '[0-9][0-9][0-9][0-9][0-9] || [A-Z][A-Z][A-Z][A-Z][A-Z]')
Thanks for any help
