or compile errors? This is not "replacement", which implies same, or at least very similar, behavior. Final Remarks You have now learnt a general pattern for error and transaction handling in stored procedures. The pattern does not work for user-defined functions, since neither TRY-CATCH nor RAISERROR are permitted there. Get More Info
Anonymous-Dave House (not signed in) Parameters Too bad Microsoft neglected to include the parameters that were passed into the stored procedure in the throw error structure. The biggest problem is that you cannot distinguish between a correctly computed 0 being returned or a 0 as the result of an error. If one of the inserts fail, or any part of the command fails, does SQL Server roll back the transaction?
If you reference @@ERROR in an IF statement, references to @@ERROR in the IF or ELSE blocks will not retrieve the @@ERROR information. Now I am intentionally trying to insert a char in Roll field: insert into StudentDetails (roll,[Name],Address) values ('a','Abhijit','India') This will throw the following Error : Msg 245, Level 16, State 1, at Honeypot Remote FT Web Application Developer (U.S. T-sql @@error Always reraise?

Catch block then handles the scenario. But if you convert the result from NULL to Zero, then you simply get wrong and misleading results. –George Nov 26 '15 at 17:48 3 By the way, if you
If a run-time statement error (such as a constraint violation) occurs in a batch, the default behavior in the Database Engine is to roll back only the statement that generated the http://stackoverflow.com/questions/1749719/sql-server-transactions-roll-back-on-error If you just wanted to learn the pattern quickly, you have completed your reading at this point. @@error In Sql Server Example The Coalesce replaces the resulting NULL by 0. –GuiSim Apr 16 '14 at 15:59 3 PLEASE! Sql Server @@error Message And if you're new to error handling in SQL Server, you'll find that the TRY…CATCH block and the THROW statement together make the process a fairly painless one, one well worth
I guess that makes sense. SqlEventLog offers a stored procedure slog.catchhandler_sp that works similar to error_handler_sp: it uses the error_xxx() functions to collect the information and reraises the error message retaining all information about it.

With the THROW statement, you don't have to specify any parameters and the results are more accurate. To set a default value, we could use the ISNULL() or COALESCE() functions:
