sql server 2005 - IF, RAISERROR & RETURN in Stored Procedure -


i have stored procedure, proc, receives parameters. if 1 of them, @id, not null, given stored procedure, proc_a, must executed. otherwise, proc_b must executed. problem both of them may issue raiserror, want propagate through call stack displayed @ client application. however, raiserror won't stop rest of proc stored procedure should, and, since using if clause, checking if ( @@error <> 0 ) return isn't option either. choice seems using try...catch block wrap if clause , rethrow raiserror within catch block, awkwards because have cache error_message(), error_severity() , error_state() , use raiserror once again.

isn't there more elegant way?

just use try - catch block , echo original error, isn't hard do:

begin try     --used in catch block echo error     declare @errormessage nvarchar(400), @errornumber int, @errorseverity int, @errorstate int, @errorline int      --your stuff here  end try begin catch      --your error code/logging here      --will echo complete original error message     select @errormessage = n'error %d, line %d, message: '+error_message(),@errornumber = error_number(),@errorseverity = error_severity(),@errorstate = error_state(),@errorline = error_line()     raiserror (@errormessage, @errorseverity, @errorstate, @errornumber,@errorline)  end catch

also, best practice have entire procedure in try - catch, , not external procedure calls.
