How can I get the Transaction ID inside "BEGIN...COMMIT" commands?

Thank you.

WHAT do you mean by "Transaction ID"? Do you mean the level of nesting within the transaction or do you mean the IDENTITY number of a row you just inserted into a table that has an IDENTITY column?

Hi Jeff,

Please corrrect if I'm making any mistake, but I think SQL creates an unique ID to each opened transaction.
If it exist, I need to get this ID number.

Thank you for your reply.

Thats an interesting question, as far as i was aware transaction where managed at the session id, db and object id level.

All this information should be in syslocks, or you could return the session id from @@Spid.

Would interested to know if there is a unique transaction id or guid that is visible and not just internal to SQL.

That may be... but that type of thing would go to the transaction log and that particular "transaction ID" doesn't have a public facing interface function that I know of (in plain English... I don't know how to get that number using SQL ;) ).

The only number that I know you can get automatically is if the table has an IDENTITY column. Then you can use the SCOPE_IDENTITY() function to return the ID of the row you last inserted... transaction or not.
