主题：[求助]部分字段的数据填充问题

我有表A，列A1、A2、A3 和表B，列B1、B2、B3，现在要将A1、A2 填充到B1、B2中，不用数据字典，用代码怎么样实现？

可以看看这个：

表A不在datatable中。如果是直接从外部数据源获取呢？

看看这里的ExecuteReader方法：

Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.Connection Name = "数据源名称"
cmd.CommandText = "SELECT * From {表A} Where 条件语句"
dt = cmd.ExecuteReader()
Dim Cols1() As String = {"来源列一","来源列二","来源列三"}
Dim Cols2() As String = {"接收列一","接收列二","接收列三"}
For Each dr1 As DataRow In dt.DataRows
    Dim dr2 As DataRow = DataTables("表B").AddNew()
    For i As Integer = 0 To Cols1.Length -1
        dr2(Cols2(i)) = dr1(Cols1(i))
    Next
Next
