connecting mutiple data set so a single control

[OldItGuy]

I have a situation where in a legacy app (VB6) I have a grid which is populated by any one of a large number of (100+) stored procedures. Each of the procedures returns one or more rows with an identical list of columns (including column names, column data types, column order). I am basically looking at the (best) options to keep things reasonably light weight. Each procedure has its own set of parameters, each of which would result in different query plans etc. I have tried using each query to exec select into a (temp) table which is encapsulated into a "master" query which then returns a single results set, but it breaks SQL, the query optimiser returns an infinite number of rows - this is a MS documented issue. Looking for possible ways forward: generics, model view etc - any links apreciated. Something that would be happy in a wpf form would be good
