This putput just a suggestion.When a method has an out parameter, the calling code has to supply atarget variable. I would like to be able to pass null instead,indicating that I have no use for the out parameter.For example, if I have a method.bool IsValidWeight(float weight, out string error). If I run the without the optional parameter it works fine. If you specify the OUTPUT keyword for a parameter in the procedure definition, the stored procedure can return the current value of the parameter to the calling program when the stored procedure exits.
To save the value of the parameter in a variable that can be used in the calling program, the calling program must use the OUTPUT keyword when executing the stored procedure. The following example shows a stored pqrameter with an input and an output parameter.

Those values can be used for a variety of purposes during optional output parameter bar execution.
