To my understanding, polymorphism means more than one function with same name
but different signature(Sorry C++ days!!).
That still can not return rwos of two types in one call. At any moment, rowset
returned by a function call would be homogenous.
Is MSSQL allows to mix rows of two types in single function invocation, I am
sure that would be a hell lot of porting trouble..
Just a thought..
