SQL Server output parameter issue

Question

I am using SQL Server 2008 Enterprise. I am learning OUTPUT parameter of SQL Server stored procedure. For example, stored procedure sp_add_jobschedule has an OUTPUT paramete

Answer 1

Think about OUTPUT PARAMETERS as passed by reference in programming languages, it's the same. The best example I can think right now is returning error code. You want some insert... if you select the return code from the SP you have to fetch it back in your code, with OUTPUT parameter you don't have, it will be already in your parameter (I mean using C# commands, PHP init stored proc methods, or something different then constructing strings)
