例如
Dim cmd As new SQLCommand
Dim dt As DataTable
cmd.CommandText = "select * From {表B}"
dt = cmd.ExecuteReader(True) '记得将参数设置为True
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 DataTables("表A").Select("[金额] > 100")
Dim dr2 As DataRow = dt.AddNew()
For i As Integer = 0 To Cols1.Length -1
dr2(Cols2(i)) = dr1(Cols1(i))
Next
Next
dt.Save
