I need to run the alter table to drop a default. However, the default name is kind of 'dynamic' from around 1000 databases, thus I need to run the following sql to get the name to a variable. Now, it looks the alter table statement does not like to drop a vaiable, is there a solution about it?
declare @radius_default varchar(40)
select @radius_default = (select sobj.name from sysobjects sobj
inner join syscolumns scolumn
on sobj.ID = scolumn.cdefault
where scolumn.name = 'radius' and sobj.name like '%LandMarks%')
print 'Need To Drop @radius_default: ' + @radius_default
--====================================
alter table LandMarks drop constraint @radius_default
I have a stored procedure that adds constraints from a variable: ALTER procedure [dbo].[addMyConst](@txtAuto_ourlim money OUTPUT,@txtGen_ourlim money OUTPUT)ASEXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_auto_ourlim DEFAULT ' + @txtAuto_ourlim + ' FOR Auto_ourlim')EXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_Gen_ourlim DEFAULT ' + @txtGen_ourlim + ' FOR Gen_ourlim') This works fine unless one of the variables is null or empty. Then I get the error: "Incorrect syntax near the keyword 'FOR' Evidendly SQL Server Express sees "....DEFAULT + + FOR..." but I don't know. I've fiddled with this a long time and haven't a clue how to fix it. Any help would be appreciated. Thanks, Steve
I have a default constratint on DateColumn getdate()-1
I have used enterprise manager to update it to yesterday's date everyday.
I would like to have a SQL which can check for the date in the system or even a trigger which checks when the date changes the constraint is updated itself. If this is not possible I would like to have a stored procedure which I will schedule to run as a job everyday once.
So if today 6/12/2006, the default value in the Datecolumn should be 6/11/2006.
This gives me a error, i tried but could not fix the bug.
Alter Table TABLE_NAME Alter Constraint DF_DATECOLUMN Default getdate()-1
There is a table exists in a database name tbDatabaseProviders.
I want to alter this table to add a column DatabaseProvider Also I want to add a default constraint so if nothing than 1 should be added.
Remember, the table already exists so when I write the script query then I want to first check the constraint if it exists then I dont want to add the constrait otherwise I will add it.
I was having problem to first add a constraint with the constraint name so I could find the constraint before finding it if it already exists.
I am dropping 60 out of 133 columns on a user table, but am finding that the spaceused by the table ( as shown by sysindexes.dpages ) is not being freed up. I have dropped and recreated all indexes on the table, with no effect on the dpages value, as well as running dbcc updateusage for the table. Is it not possible to free up the space used by using this method ? Is recreating and repopulating the table with only the required columns the correct / only way to do this ?
Hi.I'm getting errors like this when I try to run an upgrade script I'm trying towrite/test:altering labels to length 60Server: Msg 5074, Level 16, State 4, Line 5The object 'ALTPART_ANNOT_ANNOTID_FK' is dependent on column 'label'.I used this to bracket my script:sp_msforeachtable "ALTER TABLE ?

Hi: I need to change a column's datatype from tinyint to int as follows: alter table tableName alter column column1 int
but with error <<'DF__LandMarks__color__6A50C1DA' is depending on it.>>
However, this old default is not part of the constraint. Thus, the only way is to delete it from sysobjects.
unfortunately, the following code I have to commented since they could only be executed line by line, not within a begin...end block. --exec master.dbo.sp_configure 'allow updates', 1 --reconfigure with override --delete from sysobjects -- where name = 'DF__LandMarks__color__6A50C1DA' -- and type = 'D' --exec master.dbo.sp_configure 'allow updates', 0 --reconfigure with override
I need to update 10 server around 2500 databases with this change. I have looked INFORMATION_SCHEMA related views, but not found default related, maybe I missed something.
Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'. ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO
Hello, I have hit the wall here...can't make sense of this one.
I have a script that creates a PRIMARY KEY constraint called PK_tblDRG CODE:
ALTER TABLE [dbo].[tblDRG] ALTER COLUMN [record_id] Uniqueidentifier NOT NULL Go ALTER TABLE [dbo].[tblDRG] WITH NOCHECK ADD PK_tblDRG PRIMARY KEY CLUSTERED ( [record_id] ) WITH FILLFACTOR = 90 ON [PRIMARY]
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PK__tblDRG]') and OBJECTPROPERTY(id, N'IsPrimaryKey') = 1) ALTER TABLE [dbo].[tblDRG] DROP CONSTRAINT PK__tblDRG
I must change replication schema from: Publisher - SQL2000(8.0.2039), Disrtibuter/Subscriber - SQL2000 to: Publisher - SQL2000(8.0.2039)(The same server), Disrtibuter/Subscriber - SQL2005(9.0.2047)(new server)
I have removed all subscription, publications, distributer and publisher. So there should not be now any information about replication.
Now I want to make some changes with tables and i try to alter and drop columns on publisher database. But it wont do... I always receive messages that tables and fields are being used in replication:
ALTER TABLE Clients DROP COLUMN ABCCode Msg 4932, Level 16, State 1, Line 1 ALTER TABLE DROP COLUMN failed because 'ABCCode' is currently replicated.
I tried to use sp_MSunmarkreplinfo and sp_removedbreplication but it did not help. I also tried to drop column with sp_repldropcolumn but got this message: Invalid object name 'sysmergearticles'. Looks like server (publisher) still has information about old replication. But how to delete this information? And how can I alter and drop fields?
I need to make some changes to tables in a database. To do this requires that I "alter table" and "drop constraint" All constraints drop properly, except one. The last one will churn away forever in query analyzer and never drop. I am unable to make the necessary changes until this completes. I am guessing that there is a data issue that is keeping the constraint from being dropped. Any ideas on how to proceed? Thanks!
I can't seem to get the syntax correct for ALTERing an existing column with a default constraint. I've been to Help and BOL. There are examples that show how to use the ALTER command to add a column with a default constraint but not how to do it on an existing column.
I am writing a procedure to drop a specific user's schema only. I select all his/her table name and foreign key in a temp table first and then use a cursor to get the table name and foreign key, and begin drop foreign keys and drop table. However, sql think it is wrong with the syntax like "alter @table_name". Does anyone have a clue, what is wrong with my syntax. Or someone know how to drop one specific user's schema only (Other user may have same table in the database, and you don't want to drop that.
Attached is my scripts: please correct it. Thanks.

Thought I should post in the newbie forum for a while, instead. :-)
I have a couple of scripts that I've generated that drop a couple of system stored procedures and recreate them. I'm not sure why I did it in the first place, but I think it was that it wouldn't let me run an ALTER statement on them. Specifically, I'm now looking at sp_add_operator. I changed it to a 500 character email field instead of whatever it was (100, I think.)
/* Explanation: Why did I do that? SQL Mail is prohibited here, so I'm using CDO_Sysmail to email myself and the developers if a job fails. The list of people to email is determined by the owner of the database, who is also an operator in SQL. I get the list of emails from the email field of the operator properties. Hence, I need a bigger email field. Yes, I now know it would most likely be better to create an ADMIN database on each server for this kind of stuff. (Thanks to Tara for that blogged suggestion.) */
While I will probably go back to the default stored procedure, this got me to thinking: when would it be better to use an ALTER statement on a SProc rather than to do a DROP and CREATE?
I need to know definitively when I need to drop and recreate column statistics (histogram) when altering a column. Empirically, it seems I can lengthen a varchar or change a not null column to a nullable one, and then existing statistics dont' cause
Msg 5074, Level 16, State 1, Line 1
The statistics 'c1' is dependent on column 'c1'.
Msg 4922, Level 16, State 9, Line 1
ALTER TABLE ALTER COLUMN c1 failed because one or more objects access this column.
But, if I change a column to not nullable or shorten a column, I get the error.
Is this the complete description of when I need to drop and recreate column statistics and when I don't?
Is there any way to remove the IDENTITY property of a column? I originally used it, but it caused so many headaches with ADO.NET that I've decided to just increment the darn things manually. So I want to turn it into just a normal integer column.
If there's no direct way, can someone suggest a quick way to create a new column, copy all the old values into the new column, change the primary key to the new column, and drop the old column?

Hi all, I am trying to create a CONSTRAINT but for some reason T-SQL does not allow me to do that.
When I try to DROP a CONSTRAINT it says:
Msg 3728, Level 16, State 1, Line 13'DF_TBL_SyncTable_DEVUK' is not a constraint.Msg 3727, Level 16, State 0, Line 13Could not drop constraint. See previous errors.
When I try to ADD a CONSTRAINT it says: Msg 1781, Level 16, State 1, Line 14Column already has a DEFAULT bound to it.Msg 1750, Level 16, State 0, Line 14Could not create constraint. See previous errors.
For some reason I can't win here. Can't drop it nor can I create one. Any solution?

Thanks for comments + suggestions.
*UPDATE*
I am trying to use the following code to check if the SCHEMA exists but still no luck. For some reason when I create it and wrap an IF statement around it, it doesn't detect the SCHEMA. Is something wrong with my code?
Code Snippet
IF EXISTS(
SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE CONSTRAINT_SCHEMA = 'dbo'
AND CONSTRAINT_NAME = 'DF_TBL_SyncTable_DEVUK'
AND TABLE_NAME = 'TBL_SyncTable'
) SELECT * FROM TABLE_1 ELSE ALTER TABLE TBL_SyncTable ADD CONSTRAINT DF_TBL_SyncTable_DEVUK DEFAULT 2 FOR DEVUK
I have a VIEW which is dynamically generated through complex dynamic SQL. Unfortunately the dynamic SQL uses "Select * from table" to select the columns because the programmer did that to reduce the amount of code in the dynamic SQL string as the code can't be debugged if it's too long.
Therefore, I have a VIEW with columns in it I don't need, and want to remove them from the view - I need to remove all columns with column names matching the syntax '%1%_2' .
The view is called TEMP_EXPORT_1
I can either use the code below to return a list of columns that I want removed:
select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name like '%1%_2'
Or I can use the code below to return the list of columns that I want to keep:
select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name not like '%1%_2'
Now how would I go about altering TEMP_EXPORT_1 view so that it no longer has these columns? I know views don't have a drop statement...
Therefore I tried the following but I'm not sure of the syntax:
ALTER VIEW dbo.TEMP_EXPORT_1 AS SELECT (select column_name from information_schema.columns where table_name='TEMP_EXPORT_1' and column_name not like '%1%_2') FROM dbo.TEMP_EXPORT_1
Am I on the right track? how can I ALTER this view to remove these columns? ... I want to keep this separate from the code that generated the view as I want it as an optional procedure that can be run if needed.
We have a generic sql login "prduser". Applications use this login. We want the login NOT to have ALTER PROCEDURE and DROP PROCEDURE permissions only on the stored procedures(there are thousands of them).
I have two tables Person & Location where Location has a primary key LocationId and Person has a foreign key LocationId.
Sometime ago I used the Database Diagrams visual tool of SQL Server Management Studio Express to create the foreign key relationship between the two tables - i.e. "visually" (drawing a line between the PK & FK LocationId elements of both tables).
Time has passed and I recently noticed that, upon retrieving my saved diagram, the foreign key relationship had "fallen off" (i.e. the many-to-one line was no longer showing in the diagram).
After recreating the relationship (redrawing the line) I find that I get an error message when I try to save the diagram:
Post-Save Notifications [!] Errors were encountered during the save process. Some database objects were not saved.
'Location' table saved successfully 'Person' table - Unable to create relationship 'FK_Person_Location'. The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Person_Location". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
When I go back to the object explorer and view the dependencies for the two tables, there is no dependency (between these two tables) revealed. When I try to create the foreign key constraint manually (T-SQL) it again says can't add the constraint. It comes up with an error as follows:
ALTER TABLE Person ADD FOREIGN KEY (LocationId) REFERENCES Location (LocationId)
Msg 547, Level 16, State 0, Line 2 The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK__Person__LocationId__793DFFAF". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
(Note: Each time I do this, the 8 hexadecimal character suffix changes.)
When I try to drop the foreign key:
alter table Person drop constraint FK__Person__LocationId
it comes back with the error:
Msg 3728, Level 16, State 1, Line 2 'FK__Person__LocationId' is not a constraint. Msg 3727, Level 16, State 0, Line 2 Could not drop constraint. See previous errors.
So it seems that there's some kind of goof up here. Can anybody shed light on this / tell me how to fix it?
