There's an SP that in effect returns a table -- it loops and executes
statements like SELECT @field1, @Field2, @Field2

Can I capture its results in a table? I know that if it were a FUNCTION
that returned a table, that would be simple:

INSERT ResultsTable SELECT * FROM dbo.Function (@Param1, @Param2)

But how to do that if the code is a procedure rather than a function?
