Stored Proc Block Using BEGIN/END

    Hi All,

    Hopefully a very simple question:

    Stored procedures have a BEGIN and END statement around the entire contents of the stored proc. Does that mean that every TSQL statement within the stored proc is turned into a single transaction? If the stored proc contains 1 INSERT followed by 10 UPDATES on that table, will all the processing be taking place in the temp space rather than on the actual table with the results of the 1 INSERT and 10 UPDATES only being reflected in the actual table when that final END statement is reached?

    Thanks, Alan.

    No.

    Begin != Begin transaction

    Begin...End are just used to group code together. eg

    IF (condition)

    Begin

    Do lots of things

    End

    Unless you explicitly begin a transaction, SQL works in autocommit, where each statement is in its own transaction and committed automatically once it finishes

    Thanks for your prompt reply Gail. I suspected as much but didn't want to make a fool of myself without checking first!

    The real fact is, you don't need BEGIN/END in a stored procedure. Try it... it's just allowed to make die hard Oracle programmers happy 😛

    ________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.
