I'm trying to perform update operation on winform using connected ado.net layer.

here's the code

```
                string insertCmdStr = "UPDATE ARTICLE(SecondId,Group,Code,Name) WHERE (ID=@P1)";
                insertCmdStr += "VALUES(@Idd,@group,@code,@name)";
                FbCommand cmd = new FbCommand(insertCmdStr, fbConn, tran);
                cmd.Parameters.AddWithValue("@P1", id);
                cmd.Parameters.AddWithValue("@Idd", idd);
                cmd.Parameters.AddWithValue("@group", group);
                cmd.Parameters.AddWithValue("@code", code);
                cmd.Parameters.AddWithValue("@name", name);    
                cmd.ExecuteNonQuery();

```

using this query I'm getting exception
