单独生成的代码：
'''
dim dackj as string
With tables("表A")
Dim ba As  Row = .current
for each biaoc as datarow in  datatables("表C").select("[编号] = '"& ba("编号") &"'")
   if biaoc("结果") = "检出"  then
       dackj =  dackj & "," & "编号" & biaoc("序号")   
       .current("结论") = dackj & "不合格"
    end if
next
End With

全部生成的代码：（本来的思路是希望移动1行，就生成1行的结论，但没有想到：是移动，但会加上上一行的结论）

'''
dim dackj as string
With tables("表A")
for i as integer = 0 to .count
    .Position =  i
Dim ba As  Row = .current
for each biaoc as datarow in  datatables("表C").select("[编号] = '"& ba("编号") &"'")
   if biaoc("结果") = "检出"  then
       dackj =  dackj & "," & "编号" & biaoc("序号")     
       .current("结论") = dackj & "不合格"
    end if
next
next
End With

请帮助修写，或重新写也行(能实现需要的结果就行了，又是试了好久不成功）

终于找到1种可以实现的方法（用计算代码）



但想不通，（以下的代码也不行，晕中....）

'''
With tables("表A")
for i as integer = 0 to .count
    .Position =  i

dim dackj as string
with tables("表A.表C")
For r As integer = 0 To .Rows.Count - 1
   if  .rows(r)("结果") = "检出"  then
       dackj =  dackj & "," & "序号" & .rows(r)("序号")
      tables("表A").current("结论") = dackj & "不合格"
      end if
next
end with

next
End With

 

'''
dim dr1,dr2 as datarow
dim bj,dackj as string
dim dt1,dt2 as datatable
dt1 = datatables("表A")
dt2 = datatables("表C")

for Each dr1 in dt1.select("[编号] >''")
    bj = "[编号] = '" & dr1("编号")
    bj = bj & "'And [结果] = '检出'"
    if dt2.Find(bj) Is Nothing  then
        dr1("结论") = "全部合格"  
    Else
        for each dr2 in Dt2.select(bj)
             dackj =  dackj & "," & "编号" & dr2("序号")        
        next
        dr1("结论") = dackj.substring(1) & "不合格"

    End If
next

可能我说得不清楚，我要的是1楼图1的结果：

如20080001 我要的是1，38不合格
200800002  我要的是47不合格  （而不是要1，38，47不合格。这是2008001和20080002二个结果合并了）
200800003  我要的是53不合格  （而不是要1，38，47，53不合格，这是20080001、20080002、20080003三个结果的合并了）

'''
dim dr1,dr2 as datarow
dim bj,dackj as string
dim dt1,dt2 as datatable
dt1 = datatables("表A")
dt2 = datatables("表C")

for Each dr1 in dt1.select("[编号] >''")
    bj = "[编号] = '" & dr1("编号")
    bj = bj & "'And [结果] = '检出'"
        dackj = ""
        for each dr2 in Dt2.select(bj)
             dackj =  dackj & "," & "编号" & dr2("序号")        
        next
        dr1("结论") = dackj.substring(1) & "不合格"
Next

先顶1下，8楼符合要求.....


没有想到6楼知我想要的，写法应是这个：

'''
dim dr1,dr2 as datarow
dim bj,dackj as string
dim dt1,dt2 as datatable
dt1 = datatables("表A")
dt2 = datatables("表C")

for Each dr1 in dt1.select("[编号] >''")
    bj = "[编号] = '" & dr1("编号")
    bj = bj & "'And [结果] = '检出'"
             dackj = ""
        for each dr2 in Dt2.select(bj)
             dackj =  dackj & "," & "编号" & dr2("序号")        
        next
        if dackj <> "" then
            dr1("结论") = dackj.substring(1) & "不合格"
        else
            dr1("结论") = "全部合格"
       end if
Next

流程加多了1个 dackj = ""  才能实现.....请问它的作用是？
