I have an application that has a table valued function and the database that it is installed has a collation sequence that is different from the server default and it generates an error when it's run.
So, do table valued functions create temp tables in tempdb?

Everyone's favorite answer: it depends. If you have an inline function that is returing a table value, it effectively works like a view and the query processor blows out the query within the execution plan of the query it's running in. A multistatement UDF returns a table variable. Table variables do get written to tempdb.

Yes, they do... Please refer to Q4/A4 at the following URL...

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
