从报表中的两个表中查询

我的VB应用程序通过ODBC打印报告。 我使用数据库专家添加了表格，并devise了Crystal Report。 我在哪里把我的查询？ 这是我的查询

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` AND tf.`ADMINISTRATOR` = 1 AND tse.`SECTIONNAME` = '" & lblsect.Text & "' 

Answer 1

在Crystal报表向导中，find使用用户名和密码创build的odbc。

然后你会看到一个命令文本，你可以把你的查询在那里。

这个代码为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 

此代码适用于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(); 

您的水晶报告参数名称必须与您的代码隐藏中的相同。
