We can get the results from a stored procedure either in the form of the OUT or INOUT parameters or as result sets. In this recipe, we will discuss returning result sets in stored procedures. A stored procedure can be invoked either from a client application or from another stored procedure. If we return a result set from a procedure, we need to decide where to return it. We can return the result set to its caller or to the client. If it's returned to CALLER, then the result sets are not available at the end client.
