...I found this write-up useful in explaining the benefits -- and issues -- related to XACT_ABORT and TRY..CATCH: http://www.simple-talk.com/sql/t-sql-programming/defensive-error-handling/.

For example, there's a nice demonstration of how XACT_STATE() is needed to catch uncommittable transactions, following something as simple as a failed type conversion from string to integer [SELECT CAST('abc' AS INTEGER)].

An excellent article, that should be compulsory reading for all us SQL developers!

Thanks for posting Rich.

YW, thanks for letting me know you found it useful!

Great question! You'd be surprised to know how many SQL developers think if any error is encountered within a transaction it automatically gets rolled back like when XACT_ABORT is on.

I answered 1 row.

Assuming violation is at second row so first row will be xcuted succesffully. One more thing i didn't notice that all three insert statements are inside a transaction.

But if it is implict transaction and set xact_abort is ON
Then first row will be inserted sucessfully..
