Programmatically set identity seed in a table variable

Question

I need to create a table variable with an identity seed that starts with the max value of a field in another table?

I\'ve tried this:

DECLARE @Identi         


        

Answer 1

You can check the current value of an IDENTITY column by using:

DBCC CHECKIDENT (#HH)

and you can also change that later on using:

DBCC CHECKIDENT (#HH, RESEED, 42)

and that also works with a variable for the new value:

DBCC CHECKIDENT (#HH, RESEED, @IdentitySeed)

It works for local and global temporary tables (i.e. CREATE TABLE #HH (...) or CREATE TABLE ##HH (....) - but it doesn't seem to work with table variables :-(

Sorry, it seems you can't do this with table variables.....
