ช่วยผมดูที่ครับทำไหมมันบันทึกลงsqlมันได้อ่ะครับ Must declare the scalar variable "@date_pic".

sql = "insert into db.xcv  values( @date_pic, @uproduct, @parid, @shift, @customer, @gen,@number_ncr, @bai, @p1, @p2, @p3, @p4, @p5, @p6, @p7, @p8, @p9)"
        cmd = New SqlCommand(sql, cn)
        cmd.Parameters.Clear()
        cmd.Parameters.AddWithValue("date_pic", DateTimePicker1.Value)
        cmd.Parameters.AddWithValue("uproduct", txtuproduct.Text)
        cmd.Parameters.AddWithValue("parid", txtparid.Text)
        cmd.Parameters.AddWithValue("shift", txtshift.Text)
        cmd.Parameters.AddWithValue("customer", txtcustomer.Text)
        cmd.Parameters.AddWithValue("gen", txtgen.Text)
        cmd.Parameters.AddWithValue("number_ncr", txtnumberncr.Text)
        cmd.Parameters.AddWithValue("bai", txtbai.Text)
        cmd.Parameters.AddWithValue("p1", txtp1.Text)
        cmd.Parameters.AddWithValue("p2", txtp2.Text)
        cmd.Parameters.AddWithValue("p3", txtp3.Text)
        cmd.Parameters.AddWithValue("p4", txtp4.Text)
        cmd.Parameters.AddWithValue("p5", txtp5.Text)
        cmd.Parameters.AddWithValue("p6", txtp6.Text)
        cmd.Parameters.AddWithValue("p7", txtp7.Text)
        cmd.Parameters.AddWithValue("p8", txtp8.Text)
        cmd.Parameters.AddWithValue("p9", txtp9.Text)

      

        If cmd_excuteNonquery() = 0 Then
            msgbox_fail("บันทึกไม่สำเร็จ")
        Else
            msgbox_ok("สำเร็จ")
