Listing 12: The error message returned by the UpdateSales stored procedure As you can see, SQL Server 2012 makes handling errors easier than ever.

Db2 Sql Error

If Err = 0 then its good or no error, if its -1 or something else then something bad happened. */ SELECT ISNULL(@Err,-1) AS Err, @Phone_ID END TRY BEGIN CATCH IF But as I mentioned earlier, the rules that govern RAISERROR are a bit quirky.
