Even if you've been using the TRY…CATCH block for a while, the THROW statement should prove a big benefit over RAISERROR. this contact form

We do so for FETCH, because the most likely error with a FETCH statement is a mismatch between the variables and the column list in the cursor. I get, e.g., Msg 2732, Level 16, State 1, Line 9 Error number 8xxx is invalid. MS has a pretty decent template for this behavior at: http://msdn.microsoft.com/en-us/library/ms188378.aspx (Just replace RAISERROR with the new THROW command). Notice the initial check for @mode where I raise an error in case of an illegal mode and exit the procedure with a non-zero value to indicate an error. https://msdn.microsoft.com/en-us/library/ms175976.aspx
