我在水晶报表中显示连接表的数据内容时遇到问题,我的 sql 查询很好,它显示了我自己的数据,但是当我填充水晶报表数据源并显示水晶重复副本和更多数据时,我的代码是:
Dim rep As CrystalReport1 = New CrystalReport1()
Dim objcon = New SqlConnection("data source=(local);initial catalog=hesabres;user id='sa';password='Maysam7026'")
Dim objcom = New SqlCommand
Dim objdata As New DataTable
Dim objdr As SqlDataReader
objcom.CommandText = " SELECT customer.customer_name, customer.customer_tel, orders.order_stuff_name, orders.order_number" & _
" FROM hesabres.dbo.orders orders inner JOIN hesabres.dbo.customer customer ON orders.order_customer_id=customer.customer_id"
objcom.Connection = objcon
objcon.Open()
objdr = objcom.ExecuteReader
objdata.Load(objdr)
rep.SetDataSource(objdata)
CrystalReportViewer1.ReportSource = rep
