Question

How can we define output parameter size in stored procedure?

Answer 1

You can't. Of course, you are in control of how much data you put into the OUT parameter in the stored procedure. If you want you can create a sized local variable to hold the data and then assign the value of that variable to the OUT parameter.

The calling program determines the size of the variable that receives the OUT parameter.
