Try with RAISERROR('Already exist',16,1) You should return 16. Is the default, most used error level: Indicates general errors that can be corrected by the user What do the different RAISERROR severity levels mean? share|improve this answer edited Mar 2 '14 at 11:30 answered Mar 2 '14 at 11:24 Steve 144k1388164 It works for me :) Thanks –Waqas Ali Jun 11 '15 at 9:56 add a comment| up vote 2 down vote Your if statement

See more: C# SQL fI have an application that calls a stored procedure. The stored procedure is supposed to query an external ODBC database for all available tables and data. There are some known tables that cause an error and I have accounted for them by wraping the execution in a TRY...CATCH block. When I run the stored procedure from SQL Management Studio it will display the errord tables and finish executing. However, when I call it from my C# application it will return a Timeout error when it hits that first error table. Is there a way to force a Stored procedure to continue to execute and not return the error to the C# applicaion?SQL Code:- @tableName is derived from searching all available tables in the external ODBC database.BEGIN TRY SET @command = '' SELECT @command = 'SELECT * INTO [' + @tableName + '] FROM EXTERNAL DATABASE.' + @tableName EXECUTE(@command)END TRYBEGIN CATCH PRINT 'Error processing the table: ' + @tableName END CATCHC# Code:sqlCommand.ExecuteNonQuery();catch(SqlException sqle){ Console.WriteLine(sqle);} Posted 22-Feb-11 9:35am claytoC001344 Updated 23-Feb-11 2:28am v2 Add a Sol
