The opinions expressed here represent my own and not those of my employer. The deadlock victim error will cause execution to jump to the CATCH block and the transaction will enter an uncommittable state. The transaction is wrapped in a TRY/CATCH block.

The application is running a stored procedure which has a transaction in it. I start by using the @@TRANCOUNT function to determine whether any transactions are still open. @@TRANCOUNT is a built-in SQL Server function that returns the number of running transactions in the What is important is that you should never put anything else before BEGIN TRY. Sql Raiserror Custom Message The pattern does not work for user-defined functions, since neither TRY-CATCH nor RAISERROR are permitted there.
It also shows how to use RAISERROR to return information about the error that invoked a CATCH block.NoteRAISERROR can generate errors with state from 1 through 127 only.

Severity levels greater than 25 are interpreted as 25. Caution Severity levels from 20 through 25 are considered fatal.
