主题：内部数据源关联外部数据源问题

不同的数据源，不能直接写sql语句。

你要用代码处理，如

Dim idx As String = "-1,"
For Each dr As DataRow In DataTables("表A").DataRows
    If DataTables("表B").find("编码 = '" & dr("编码") & "' and 金额 = '" & dr("金额") & "'") Is Nothing Then
        idx &= dr("_Identify") & ","
    End If
Next
Tables("表A").Filter = "_Identify in (" & idx.trim(",") & ")"
