Query from two tables in report

mysql

My VB application prints a report via ODBC. I added the tables using database
expert and designed the Crystal Report. Where do I put my query? here is my
query

SELECT ts.`SCHEDIDNO`,
       ts.`DAYNAME`,
       DATE_FORMAT(ts.`TIMESTART`, '%h:%i %p') as TIMESTART,
       DATE_FORMAT(ts.`TIMEEND`, '%h:%i %p') as TIMEEND,
       ts.`GRADELEVEL`,
       ts.`SECTIONNAME`,
       ts.`SUBJECTNAME`,
       ts.`FACFULLNAME`,
       ts.`ROOMNAME`,
       tf.`FACFULLNAME` as PERSONNEL,
       tf.`DEPARTMENT`,
       tse.`Adviser`
FROM `tblschedule` ts,
     `tblfaculty` tf,
      `tblsection` tse
WHERE ts.`GRADELEVEL` = " & lblgrade.Text & "
    AND ts.`SECTIONNAME` = '" & lblsect.Text & "'
    AND ts.`DEPARTMENTNAME` = tf.`DEPARTMENT`

In Crystal report wizard, locate your odbc created with username and password.

Then you will see a Command text, You can put your Query in there.

This code for VB.NET

 Private CRPT As New ReportDocument
    Private APPPATH As String
    Private PARAM As New ParameterFields
    Public PARAM_DESC As New ParameterDiscreteValue
    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        APPPATH = Application.StartupPath & "\REPORT\sample.rpt"
        CRPT.Load(APPPATH)
        Me.CrystalReportViewer1.ReportSource = CRPT

        PARAM = CRPT.ParameterFields

        PARAM_DESC.Value = Format(DatePicker1.Value, "yyyyMMdd")
        PARAM("DATEP").CurrentValues.Clear()
        PARAM("DATEP").CurrentValues.Add(PARAM_DESC)
        Me.CrystalReportViewer1.Refresh()
    End Sub

This code is for C#:

CRPT = new ReportDocument();
            APPPATH = Environment.CurrentDirectory + "Sample.rpt";
            CRPT.Load(APPPATH);
            Report_Viewer.Refresh();
            CRPT.SetParameterValue("syear", Servercls.year);


            CRPT.SetParameterValue("smonth", Servercls.month);
            CRPT.SetParameterValue("sday", Servercls.day);
            CRPT.SetParameterValue("datevalue", Servercls.Datevalue);
            Report_Viewer.ReportSource = CRPT;

            sc.configureCrystalReport();
            Report_Viewer.Refresh();

Your crystal report parameter name must be the same with in your Code Behind.
