一、使用視圖meeting將多表關(guān)聯(lián)整合在一起

二、通過(guò)Sql語(yǔ)句篩選數(shù)據(jù)

三、建立和主從表的關(guān)聯(lián)

四、注意在CrystalReport1表中插入子報(bào)表的時(shí)候，一定要將主從表的關(guān)聯(lián)字段設(shè)置好，否則出亂子

主體代碼如下：

/// <summary>
  /// Bind CrystalReport
  /// </summary>
  /// <param name="strS">sql</param>
  PRivate void bdReport(string strS)
  {
   oCR = new CrystalReport1();
   SqlConnection cnn = new SqlConnection(ConfigurationSettings.AppSettings["ConnectionSqlServer"]);

   SqlDataAdapter cmd1 = new SqlDataAdapter(strS,cnn);

   //Create and fill the DataSet.

   DataSet2 ds = new DataSet2();
   cmd1.Fill(ds,"meeting");

   // SqlDataAdapter cmd2 = new SqlDataAdapter("select * from realplan where rplanid in (select top 10000 planid from ("+sqlStr+")as  a order by planid)", cnn);
   SqlDataAdapter cmd2 = new SqlDataAdapter(SqlIsOper, cnn);
  
   cmd2.Fill(ds,"realplan");

   //Create the relation between the Authors and Titles tables.
   ds.Relations.Add("mo",
    ds.Tables["meeting"].Columns["planid"],
    ds.Tables["realplan"].Columns["rplanid"]);

   //binding reportViewer
   oCR.SetDataSource(ds);

   this.CrystalReportViewer1.ReportSource = oCR;

   //Close the connection.
   cnn.Close();
  
  }
