Hi jignesh

If you use an IDENTITY column it will be incremented automatically and you can get the value with SCOPE_IDENTITY() function. If you don't have an IDENTITY column use a ID-table where applications/procedures get their ID-ranges to work with. Avoid a select MAX to determine the next possible ID.

To add to what Flo stated... if you insert more than one row with an IDENTITY column, you can use OUTPUT to capture all of the IDENTITIES created as a result set.

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.
