主题：数据填充器

看2楼,直接编码赋值,喜欢怎么来就怎么来,自由控制.请先看一下

我的感觉fill较慢，数据量较大时更慢，要一条一条写入，有时数据量较大时，还不如先导出access再倒入access，不知道行不行

还是没搞懂怎么给  关联的日期列  赋值父表的日期

Dim Cols1() As String = {"编号"}
Dim Cols2() As String = {"编号"}
For Each dr1 As DataRow In DataTables("产品资料").Select("[月销量] > 100")
     Dim dr2 As DataRow = DataTables("采购明细表").AddNew()

     For i As Integer = 0 To Cols1.Length -1
         dr2(Cols2(i)) = dr1(Cols1(i))

     Next
 Next

Dim Cols1() As String = {"编号"}
Dim Cols2() As String = {"编号"}
For Each dr1 As DataRow In DataTables("产品资料").Select("[月销量] > 80")
    Dim dr2 As DataRow = DataTables("采购明细表").AddNew()
   
    For i As Integer = 0 To Cols1.Length -1
        dr2(Cols2(i)) = dr1(Cols1(i))
    Next
   
    dr2("日期") = Tables("采购主表").Current("日期")
Next

 

这样也行   不过问题解决了    呵呵    感谢甜老师的耐心解答
