一、使用视图meeting将多表关联整合在一起
二、通过Sql语句筛选数据
三、建立和主从表的关联
四、注意在CrystalReport1表中插入子报表的时候，一定要将主从表的关联字段设置好，否则出乱子
主体代码如下：
///
/// Bind CrystalReport
///
///
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();
}
