Check out the Message and number, it is 245. I come to know about Dot Net Tricks innovative way of providing real time project based training in 2014 through one of my friend who have taken class from Dot Net If the UPDATE statement runs successfully, the SalesLastYear value is updated and the operation is completed, in which case, the code in the CATCH block is never executed. Will absolutely recommend to anyone looking for real time, hands on technical training! http://babylonware.com/sql-server/error-handling-in-user-defined-functions-in-sql-server-2008.html

Using ERROR_MESSAGE in a CATCH blockThe following code example shows a SELECT statement that generates a divide-by-zero error. Instead I used your solution plus ISNULL and MAX. Thanks. We can handle error by checking @@ERROR and @@ROWCOUNT in combination and then use RAISERROR or RETURN to return error message or code to application 3.
