I am using the ADO command object to execute a stored procedure on Sybase (a DB like SQL Server). The stored proc has parameters, so I create ADO parameter objects and append them. Normally this works fine. The problem arises when I want to pass the Null value to a parameter. There is no adNull parameter type, and passing a variant containing Null to a parameter defined as adVariant gives a "unsupported type" error. Anyone know how to create a null parameter?
