Why not just use this:

cmd.CommandText = "UPDATE orpay SET depdate='" & @depdate1 & "' WHERE tag=1";

It will save you an RPC.

>hi,

>i'm trying to update my database using an ExecuteNonQuery(), but i'm getting an error message 'system error'. i've narrowed it down to the parameter @depdate1 bec i tried setting depdate='01/01/2001' and it worked fine. my guess is i'm not using the parameter correctly. any ideas? thanks.
