The thread you had referenced sounds somewhat familiar in that this error happens sometimes. Also, the view parameters I have are both integer types so the alltrim or padr functions don't apply. Additionally, the view ALWAYS works when I browse it through the VFP interface (after entering the parameters). So I don't think posting the SQL will accomplish anything. I get the error on SOME parameter combinations when using the standard business object of the MERE Mortals Framework and executing the requery method of the business object.

Are you familiar with MERE Mortals?
