筛选后如何排除重复值 - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

老师您好，

我是想筛选后排除重复值，或者是先排除重复值再筛选，但下面的代码红色部份似乎没有效果，怎么办

dim tbl as table = Tables("选择商品_table1")

If txt = "" Then

tbl.Filter = " "

Else

txt = "'%" & txt & "%'"

tbl.Filter = "商品ID Like " & txt & " Or 商品名称 Like " & txt & " Or 拼音码 Like " & txt & ""

Tables("选择商品_table1").RepeatFilter("商品名称", 1)

End If

代码没问题，请具体说明什么问题，或者上传具体实例测试。

经过我反复测试，我终于可以详细的描述这个问题了....！

下面蓝色部份代码，如果只有两项筛选的话，代码没有问题，有三项筛选的话‘排除复’就没有效果，有趣的是当你在文本框里输入商品ID和商口名称筛选的时候没有效果，而输入拼音码筛选则有效果

dim tbl as table = Tables("选择商品_table1")

If txt = "" Then

tbl.Filter = " "

Else

txt = "'%" & txt & "%'"

tbl.Filter = "商品ID Like " & txt & " Or 商品名称 Like " & txt & " Or 拼音码 Like " & txt & ""

Tables("选择商品_table1").RepeatFilter("商品名称", 1)

End If

End If

可以了，没想到需要这么长的代码来实现，辛苦了，甜老师

顺便问一下，符号 “ &= ” 是什么意思

a &= "123"

等同于

a = a & "123"
