Dropping An Old Foreign Key Restraint?
Jul 6, 2007
This forum looked like the only one where I may get an answer to this question.
I built a database with a set of tables in Sql Server 2005 sp2.
I later had to refactor the data which led to removing one table, renaming another table, and moving some data around.
Now when I attempt to write my test code and execute my initialization logic (which clears data out of the tables) I get a foreign key restraint error when trying to delete one of my records. However the FK restraint is an old one that refers to a table that no longer exists. I have looked at all of my tables in the current design and the constraint referenced in the exception does not show up on any of the tables.
How things changed: I had DesktopItems tie to a DataEntry table with a foreign key constraint. I now have DesktopItems point to WorkItem ( the orgininal table renamed ) and it is on the delete of items from DesktopItems that I get the old FK constraint. The really odd part about this is if I go into the table and manually delete the record, I do NOT get the constraint error!!!
In the database that I'm getting the error, I implemented the changes by deleting all tables and SPROCS and then executing scripts to rebuild the new design.
Is there a system SPROC that I can execute to show and delete this item?

I am having trouble dropping constraints(Primary and Foreign Keys). I would like to do so so I can truncate the tables and repopulate them. Any time I use the DROP CONSTRAINT #### on one table, I get an error message saying this is referenced in another table. Any help in how to drop the keys so I can truncate the tables in a database would be appreciated. I must be overlooking something simple. Thanks for the help.
Regards,
Mark

Is there a way we can prevent a object owner from dropping his tables. Example:
There is a user called 'tom' who is given create table permissions, 'tom' creates the table completes his dev and then the table is moved into production where 'tom' is still the owner. However, in production, 'tom' does not have the create table privs. Because 'tom' is the owner of the table, he is still able to drop the table in production. This is what I am trying to avoid. I would like to retain 'tom' as the owner and want to take away his create/drop privs.

Hi,
I`m new at SQL Server so excuse me if this question sounds dumb.
Does anybody know how to drop columns in a table. I know I can drop and re-build the table,
but I would prefer and easier way.
Thanks

Hi,
After I drop the database, I backed up the master database, I recreate the database with new name. When I tried to do the import on the command level,
It gives me the error:
Attempt to locate entry in the sysdatabases for database 'db1' by name,
failed -- no entry found in that name.
What should I do? Thanks.

Looking for suggestions.
I have a database that is giving me a bad Index error. When I go to drop the necessary Index it is telling me that it either does not exist or cannot be dropped. However when I try to build that index, it tells me one already exists.
Is there any way to drop all of the indexes or at the very least see what the indexes are? This particular database is using 2005 Express.
Any help would be great!

How to remove the constraints on a table in sql server 2000? I need to drop the column, so i need to drop the constraint before that.
Alter Table Table_Name NO CHECK constraints ALL.
Once I execute the above one, it says, "Successfully Executed" but when I try to drop it doesnt allow me and gives me the following error:
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF_Users_Created_by' is dependent on column 'CREATED_BY'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE DROP COLUMN CREATED_BY failed because one or more objects access this column.
Any ideas?
Thanks,

I think the answer to this question will be something like 'you'll have to re-initialize the subscribers', but I need to ask anyway...
I created a publication where my foreign key constraint we NOT created with NOT FOR REPLICATION. My publication is configured to replicate DDL changes. Is there any way I can drop and re-create the constraint in the publisher and get replication to push the change to the subscribers?
Thanks for your help

Hi:
I think I am doing something wrong. I am trying to make the trigger fire when I want to drop the same trigger. For example I have the following trigger defined:
USE AdventureWorks2000
GO
CREATE TRIGGER Incheckstock
ON DATABASE
FOR DROP_TRIGGER
AS
PRINT 'You must disable Trigger "Incheckstock" to drop Trigger!'
ROLLBACK
GO
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
ENABLE TRIGGER Incheckstock ON DATABASE
DROP TRIGGER Incheckstock
ON DATABASE
I created the trigger Incheckstock and i want to see if the same trigger fires itself if when i am trying to drop the trigger with the same name (kind of recursive one). Is this possible in SQL 2005?. If I asked a dumb question, please correct me.
Thanks

I guess nobodys heard of this? I'm using DTS to transform data to Excel spreadsheet. I have a DROP TABLE `data$` then a CREATE TABLE `data$` the old data is cleared but the new data is appended to the blank rows of the old data. So if I had 5 rows before now I have 10. And the new data has 5 blank rows before it.
I've tried deleting the excel file & replacing it with a new one.
I've used the wizard thinking it was me but no good, it still happens.
HELP!

I am using Access 2000 to link tables from SQL Server. The tables are linked using ODBC DSN`s. I am running a query to return some rows to Access, but once I have returned the rows, I want to drop the linked table connection to SQL Server, because it is locking a table on the server. I think I need to write a bit of VBA code, but I don`t know where to start. Any ideas would be greatly appreciated. Thanks.

SQL 7 created by default a clustered index on my primary key field. I would like to drop this index and recreate it on another field, but it is not allowing me. Error message states: "An explicit DROP INDEX is not allowed... It is being used for PRIMARY KEY CONSTRAINT enforcement." Can anybody advise how I can solve this? TIA

I'm new to replication and would like to know how to drop an article published for replication. I believe I need to follow these steps, but I am unsure.
Step (1)
exec sp_dropsubscription @publication = N'db name',
@article = N'article name',
@subscriber = 'subscriber name',
@destination_db = N'db name'
Step (2)
exec sp_droparticle @publication = N'db name',
@article = N'article name'
Step (3)
drop the article on the publisher
Step (4)
drop the article on the subscriber
Is this the correct sequence or am I missing something.
Thanks, Dave

I'm changing the collation sequence of a field which is a primary, clustered key field via:
ALTER TABLE [dbo].[clusterAlgorithm] WITH NOCHECK ADD
PRIMARY KEY CLUSTERED
(
[ClusterAlgorithmClassName]
) ON [PRIMARY]
GO
Is there a way to drop the primary key designation before doing an alter table/alter column statement and then recreating the key, or must I drop and recreate the table?
Thanks,
Al
