ฐานข้อมูลผมเก็บ ปี/เดือน/วัน แล้วผมต้องการนำวันปัจจุบันไปตรวจสอบว่าตรงกันไหม ผมทำแบบนี้ถูกมั้ยครับ ไม่แน่ใจ

 Dim intNumRows1 As Integer
        Dim intNumRows2 As Integer
        Dim intNumRows3 As Integer

        strSQL = "SELECT COUNT(*) FROM member WHERE Username = '" & Me.txtusername.Text & "' AND Password = '" & Me.txtpassword.Text & "' "
        objCmd = New MySqlCommand(strSQL, objConn)
        intNumRows1 = objCmd.ExecuteScalar()

        strNUM = "SELECT COUNT(*) FROM book WHERE book_no = '" & Me.lblnum.Text & "'"
        objCmd = New MySqlCommand(strNUM, objConn)
        intNumRows2 = objCmd.ExecuteScalar()

        strDATE = "SELECT COUNT(*) FROM book WHERE book_date = '" & DateTime.Today & "'"
        objCmd = New MySqlCommand(strDATE, objConn)
        intNumRows3 = objCmd.ExecuteScalar()

        If intNumRows1 > 0 Then
            If intNumRows2 > 0 Then
                If intNumRows3 > 0 Then
                    Me.Hide()
                Else
                    MessageBox.Show("You Not Booked This Computer")
                End If
            Else
                MessageBox.Show("Please Booking for Use")
            End If
        Else
            MessageBox.Show("Username & Password Incorrect")
        End If

        objConn.Close()
        objConn = Nothing

    End Sub
