Ok guys, Sorry for the false alarm. I solved the problem. When I define my parameters in .NET in the order they are listed in pgAdmin, the function call works. If I use the order that they are listed in Visual Studio's Server Explorer, the function call fails. It appears Visual Studio's Server explorer is listing my function parameters incorrectly.
Thanks anyways. Rommel Edwards Software Developer, Barbados, Caribbean. ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
