-- [求助] 增加求总条件
老师，如表，增加了个列”具体日期“， 只要具体日期相同的只计算一次相同产品，以下代码该如何修改，谢谢。
Dim dt As DataTable = DataTables("表C")
Dim C As List(Of String())
C = dt.GetValues("月份|产品","产品 is not null")
Dim dr As DataRow
For Each Customer As String() In C
dr = dt.find("[月份] = \'" & Customer (0) & "\' and 产品=\'" & Customer (1) & "\'")
dr("总数量") = dt.Compute("Sum(数量)","[月份] = \'" & Customer(0) & "\' and 产品=\'" & Customer(1) & "\'")
dr("产品重复笔数") = dt.Compute("COUNT(产品)","[月份] = \'" & Customer(0) & "\' and 产品=\'" & Customer(1) & "\'")
Next

出错了， 另也没有把具体日期考虑进去。
