Dim b As New SQLGroupTableBuilder("统计表1","Sales_Order_List")

b.ConnectionName = "CRM2014"

b.AddTable("Sales_Order_Product","OrderId","Sales_Order_List","Id")

b.AddTable("Sales_Order_Product","ProductId","Sales_Product_List","Id")

b.AddTable("Sales_Order_List","CustomerId","Customer_List","Id")

b.Groups.AddDef("{Sales_Product_List}.Name")

b.Groups.AddDef("{Customer_List}.Name")

b.Groups.AddDef("SubmitDate")

b.Groups.AddDef("SubmitUserName")

b.Totals.AddDef("已交数量")

b.Build   '生成统计表

MainTable = Tables("统计表1")
