一个关于水晶报表的问题？

[hongcha99]

CrystalReport1 chec = new CrystalReport1();
DataSet cheds = new DataSet();
SqlDataAdapter sda = new SqlDataAdapter();
sda = DataBaseModel.GetSda("select (dbo.gettq1.nNum1+dbo.gettq2.nNum2+dbo.gettq3.nNum3) as sum,* from dbo.gettq1(),dbo.gettq2(),dbo.gettq3()" +"where dbo.gettq1.sCode1=dbo.gettq2.sCode2 and dbo.gettq2.sCode2=dbo.gettq3.sCode3");
chec.SetDataSource(cheds.Tables[0]);
crystalReportViewer1.ReportSource = chec;
-------------------------------------------
chec.SetDataSource(cheds.Tables[0]); 这句话报错说找不到列表0，怎么办？

chec.SetDataSource(cheds.Tables[0]);改成chec.SetDataSource=cheds.Tables[0];试试

[jhbking]

chec.SetDataSource(cheds)

试试上面的方法吧！我没遇到过！
