I am using the query below to update two values from a form.

Code:
        MasterBase.AddParam("@midno", lblMasterID.Text)
        MasterBase.AddParam("@effective", False)
        MasterBase.AddParam("@obsolete", True)
        MasterBase.MasterBaseQuery("UPDATE " & MyTable & " " &
                                   "SET Effective=@effective,Obsolete=@obsolete " &
                                   "WHERE MasterBaseID=@midno")
MyTable can be one of two tables. When this code is executed, the table should be updated, but is not. I am unable to see why the table is not updated.

I know that queries are very tricky and I often have trouble making them work. But I do not see the error here.
