Great question to brush up on Transactions. One thing that I tend to forget about, that I brushed up on before answering, is the behavior of transaction_name parameter of BEGIN TRANSACTION, COMMIT TRANSACTION, and ROLLBACK TRANSACTION.

In regards to SSChasing Mays concerns about committed transactions being rolled out, 'Committing inner transactions is ignored by the SQL Server Database Engine' (http://msdn.microsoft.com/en-us/library/ms189336.aspx).

Real committed transactions can't be rolled out ('A transaction cannot be rolled back after a COMMIT TRANSACTION statement is executed.' (http://msdn.microsoft.com/en-us/library/ms181299.aspx)).

Perhaps the related QotD answer explanation element ('... (including those inner transactions that have been committed)') could have been better worded.



Nice explanation and it also works well with the Myth a Day series explaining nested transactions by Paul Randal.

I think this is a nice question to continue the series. People should look up the article by Paul Randal on this topic http://www.sqlskills.com/BLOGS/PAUL/post/A-SQL-Server-DBA-myth-a-day-(2630)-nested-transactions-are-real.aspx

Would
COMMIT TRAN OuterTran

without the use of
COMMIT TRAN InnerTran

commit both transactions?

Thanks, and I hope I did not just ruin Part IV.
