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.

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.
What should I do the above.
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
thanks

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 guys,
If I have a temporary table called #CTE
With the columns
[Account]
[Name]
[RowID Table Level]
[RowID Data Level]
and I need to change the column type for the columns:
[RowID Table Level]
[RowID Data Level]
to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time.
What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance,
Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE
ALTER COLUMN
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE
MODIFY
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;
How can I alter a table turning ON or OFF an IDENTITY field ?
for example:
if I had my DB with Client_ID as an I IDENTITY field and for some reason it has
changed to just INT (with no IDENTITY) - how can I tell it to be IDENTITY field again ?

Does anyone knows an article on database planning ?
(I wanna know when should I use the IDENTITY field)
I am having problem when performing the alter table switch. Both tables are identical and have pk.
ALTER TABLE SWITCH statement failed. There is no identical index in source table 'LocalDeltanet.dbo.testresults' for the index 'PKIDX_testSummary' in target table 'LocalDeltanet.dbo.testresults_part' .
CONSTRAINT [PKIDX_testSummary] PRIMARY KEY CLUSTERED
( [testresult_id] ASC )
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
ON TResultsScheme (testresult_id) ) ON TResultsScheme (testresult_id)
I have performed the function on other tables successfully, but this is the first that has an identity column involved. Is there anything special that needs to be done?
[testresult_id] [int] IDENTITY(1,1) NOT NULL,
I know that TRUNCATE TABLE can be used to reset the identity counter, but it can't be used on a table referenced by a foreign key. Anybody knows how to do that? Thanks.
View 4 Replies View RelatedI 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.
Any help would be appreciated.

i have a table
table1
column1 int not null
column2 char not nul
column3 char
i want to script a change for table1 to alter column1 to be the table identity column. not primary.
I need to alter the datatype of a column from smallint to decimal (14,2) but the column was originally created with the following:
alter my_table
add col_1 smallintNot Null
constraint df_my_table__col_1 default 0
go
I want to keep the default constraint, but i get errors when I try to do the following to alter the datatype:
alter table my_table
alter column col_1 decimal(14,2)Not Null
go
Do I need to drop the constraint before I alter the column and then rebuild the constraint? An example would be helpful.
Thx

View 1 Replies View Relatedi am altering an int column to identity:
where is something wrong here?
error:

Incorrect syntax near the keyword 'IDENTITY'.
statement:

I am not able to create identity on a existing column using ALTER statement.
Can anybody help on this issue ?
I'm attempting to remove the IDENTITY property from a column using the ALTER command but can't seem to find the right syntax. I've tried every conceivable combination I can think of. I can add the property to a column that doesn't have it.
It's easy to do in Enterprise Mgr., but I want to script the change.
I really don't want to drop the table and rebuild if I don't have to.

HELLO All,
Does anybody knows how to set identity to column using ALTER Script.
Thanks in advance.

Hello All,
There is a table A in SQL. One of the column of A was IDENTITY before and was getting referenced in other table B.
During migration to SQL 2005, I removed the IDENTITY constraint and imported all the data from 2000 to 2005. Now I have to deploy the IDENTITY back to the column. I am getting an error while executing the code:
ALTER TABLE TableA
ALTER COLUMN ColumnA
ADD CONSTRAINT IDENTITY(445,1)
Can anyone tell me where I am going wrong? Or if there is any other way to do it. There are 50+ tables I need to do the same.
Thanks,

hello experts,
Any body know what is the query for modifying the identity column in a table? i mean modifying from IDENTITY column to int colum or VICE-VERSA
Thanks

Alter table table1 ADD CONSTRAINT column1_def Identity(1,1) FOR column1
they all can not work,
any idea about this? thanks
Hi,
I have been trying to figure out how to use ALTER TABLE/ COLUMN to modify a column from an IDENTITY column to one which is not an IDENTITY column.
I would like to do this so that I could add another column (using ALTER) and set it as the IDENTITY column.
Any thoughts?
Your help is much appreciated,

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?
Thanks.
trying to change a column that is just a INT NOT NULL column, to have an auto-increment.

View 4 Replies View Relatedhi,
I've done Googling and forum hunting but haven't had success finding a simple answer... My table schema is such that it requires the (int) LinkedItemID field to be nullable but still those fields which are set must not be duplicates. I see constraint is out of question and also identity doesn't seem to fit since I'm not using autofill for this particular field. Is there some other way doing this on Sql Server 2005?
Thank you.

Hello,
I've a table with primary key defined as non-clusterd, now without dropping it can I modify the existing index to clustered through tsql as I had to write some migration script and in that script I wanna do this.
Thanks in Advance,

While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,
Barkingdog
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
