These functions will return the value null outside of the CATCH block. Another function that you can invoke within the CATCH block is called XACT_STATE(), which returns the state of the transaction as an integer value: 0 means no transaction is active, 1 When SQL Server detects a deadlock, the CATCH block prints some debug information, increments the @retry value by 1, and enters a delay of 3 seconds so the other process will INSERT fails.

It is also important to communicate that an error has occurred, lest that the user thinks that the operation went fine, when your code in fact performed nothing at all.
In Transact-SQL, each TRY block is associated with only one CATCH block.Working with TRY…CATCHWhen you use the TRY…CATCH construct, consider the following guidelines and suggestions:Each TRY…CATCH construct must be inside a The output that the first connection generates includes T2's contents and a print message that says the transaction completed successfully.
