--  关于客户合计，为什么有错？

以下是合计客户销量，的代码，请问是哪里出现问题了？？

 

 

MainTable = Tables("订单")
If CustomFilter = "" Then
    CustomFilter = "1 = 1" \'或者CustomFilter = "1 = 2"
End If
Dim Cmd As new SQLCommand
Cmd.C
Cmd.CommandText = "select distinct 分区,客户编码,客户,年,月份,目标 from 专卖店目标 where " & CustomFilter
Dim dt1 As DataTable = Cmd.ExecuteReader
Dim dtb As New DataTableBuilder("统计")
dtb.AddDef("分区", Gettype(String), 50)
dtb.AddDef("客户编码", Gettype(String), 150)
dtb.AddDef("客户", Gettype(String), 150)
Dim prds As List(of String()) = dt1.GetUniqueValues("","年","月份")
Dim exp As String
dtb.AddDef("目标总额", Gettype(Double))
dtb.AddDef("销售总额", Gettype(Double))
dtb.AddDef("达成率", Gettype(Double),"[销售总额]/[目标总额]")
For Each prd As String() In prds
    dtb.AddDef(prd(0) & "_" & prd(1) & "_目标", Gettype(Double))
    dtb.AddDef(prd(0) & "_" & prd(1) & "_销售", Gettype(Double))
    exp = String.format("[{0}]/[{1}]",prd(0) & "_" & prd(1) & "_销售" ,prd(0) & "_" & prd(1) & "_目标" )
    dtb.AddDef(prd(0) & "_" & prd(1) & "_达成率", Gettype(Double),exp)
Next
dtb.Build()
Cmd.CommandText = "select 分区,客户编码,客户,year(日期) as 年,month(日期) as 月份,sum(金额) as 销售 from 订单 where " & CustomFilter & " group by 分区,客户编码,客户,year(日期),month(日期)"
Dim dt2 As DataTable = Cmd.ExecuteReader
For Each cus As String() In dt1.GetUniqueValues("","分区","客户编码","客户")
    Dim dr As DataRow = DataTables("统计").AddNew()
    dr("分区") = cus(0)
    dr("客户编码") = cus(1)
    dr("客户") = cus(2)
    For Each prd As String() In prds
        dr(prd(0) & "_" & prd(1) & "_目标") = dt1.Compute("Sum(目标)","分区 = \'" & cus(0) & "\' And 客户编码 = \'" & cus(1) & "\' And [年] = \'" & prd(0) & "\' and 月份 = \'"& prd(1) &"\'")

    Next

    dr("销售总额") = dt2.Compute("Sum(销售)","分区 = \'" & cus(0) & "\' And 客户编码 = \'" & cus(1) & "\'")
\'******************************合计行
dr = DataTables("统计").AddNew()
dr("客户") = "合计"
For Each prd In prds
    Dim ColName1 As String = prd(0) & "_" & prd(1) & "_目标"
    Dim ColName2 As String = prd(0) & "_" & prd(1) & "_销售"
    dr(ColName1) = dt1.Compute("Sum(目标)","[年] = \'" & prd(0) & "\' and 月份 = \'"& prd(1) &"\'")

Tables("统计").AutoSizeCols

 在最前面加一句

 

Dim prd() As String

 或者，把这句改一下

 

For Each prd In prds

 改成

 

For Each prd As String() In prds

 第一步：把 Dim prd() As String  去掉

 

 第二步：改成 For Each prd As String() In prds

老师，这样就会是每个客户的合计，这个不是我想要的，我想要的是，所有客户，最后合计一项即可
