Subject: Example of T-SQL exception handling within a transaction?

Anyone have an example of how to trap and exception within a T-SQL transaction and save diagnostic details on why the transaction failed to an error log? If you insert the exception data to an error table this information gets lost when you rollback the transaction. I'm sure I'm missing something obvious :) Thanks, Malcolm

Good description there on how to write one and that the THROW is necessary
within a transaction. I learned something in this because I rarely ever
write transactions due to locks being applied while it is running.

Yes, you log into a variable, roll back the transaction in the CATCH block and then insert the variable into the error log table.
