All parameter indexes are treated as relative rather than absolute. We should not accept values less than 1 and should ensure that the values specified are continuous.

Also, return parameters should be considered index 1 regardless of where they are in the procedure metadata. For example in defer_testDefect24952 in TestMMStoredProcedure ?=call sp.sp_count_rows_between(?, ?) should have a return value at index 1 from the driver perspective, but instead it has index 3.
