Exit and rollback everything in script on error

Question

I have a TSQL script that does a lot of database structure adjustments but it\'s not really safe to just let it go through when something fails.

to make things clear:

Answer 1

Try using RETURN. this will exit the script or procedure immediately and will not execute any of the following statements. You can use this in conjunction with BEGIN, ROLLBACK and COMMIT TRANSACTION statements to undo any data damage:

    BEGIN
    BEGIN TRANSACTION

    
    IF @@error <> 0
        begin
        RAISERROR ('first batch failed',16,-1)
        ROLLBACK TRANSACTION
        RETURN
        end

    
    IF @@error <> 0
        begin
        RAISERROR ('second batch failed',16,-1)
        ROLLBACK TRANSACTION
        RETURN
        end

    PRINT 'WIN!'
    COMMIT TRANSACTION
    END
