t-sql: GO,

Think of it like this: Cut up your script into multiple files,separated by the "GO" statement. Run each of these files individually,but use the same connection. That's all "GO" does.

Server never sees GO. GO is a keyword in client apps such as sqsh. I think java/perl apps don't use GO.

Until you are clear on the fundamentals above, avoid the confusing questions over auto-commit, transaction and GO. I think auto-commit means every GO-batch is a self-contained transaction. If a GO-batch issues a begin tran without ending it, then server will keep it open.

Another confusing question is GO and stored proc.
* i believe a java/perl app calling a proc won't use GO at all.
* when sqsh calls the proc, it needs GO to mark end-of-batch
* Most complicated scenario is when you create the proc in sqsh. I usually wrap the create-begin-end piece in one go-batch.
