筛选出“测评”表中的 编号相同，且姓名相同，且【删除】没有打勾 的行，以下写法有问题么？谢谢！

Tables("测评").Filter="[推荐编号]  = \'" & dr1("推荐编号") & "\'And [姓名] = \'" & dr1("姓名") & "\' and [删除] = False Or [删除] Is Null "

 筛选重复值，不能这样处理。参考下面的代码

Dim idx As String = "-1,"
Dim idx_temp As String = ""
Dim pdr As DataRow = Nothing
Dim count As Integer = 0
For Each dr As DataRow In DataTables("表A").Select("删除 = false or 删除 is not null", "第一列,第二列")
    If pdr IsNot Nothing AndAlso (pdr("第一列") <> dr("第一列") OrElse pdr("第二列") <> dr("第二列")) Then
        If count > 1 Then
            idx &= idx_temp
        End If
        count = 1
        idx_temp = ""
    Else
        count += 1
    End If
    idx_temp &= dr("_Identify") & ","
    pdr = dr
Next

If count > 1 Then
    idx &= idx_temp
End If

Tables("表A").filter = "_Identify in (" & idx.trim(",") & ")"

这样行吗？就是想筛选出推荐编号相同，且删除列不是true的列

Tables("测评").Filter="[推荐编号]  = \'" & dr1("推荐编号") &  " and [删除] = False Or [删除] Is Null "

测试下可以咯！！嘻嘻
