这个代码是先生成表，后做筛选，降低了效率，要改变为 qycx.Filter = filter 又发现Filter代码出不来了。
另外感觉这个结构太乱，反复判断，有没有什么方法简单点

效率难有什么大提示.

呃，楼主 SQLJoinTableBuilder 不是也有 Filter 的么？注意，它使用 Like 的时候，要把 * 改成 %

现在改成了这个样子，就过不去了，

在一个，你filter的生成，也很有问题，可以写成类似这样吗？
Dim Filter As String = "1=1"
If xq1 > "" Then
Filter = Filter & " And 区域 like \'%" & xq1 & "%\'"
End If
If lx1 > "" Then
Filter = Filter & " And 项目类型 like \'%" & lx1 & "%\'"
End If
msgbox(Filter)

回复4楼，请看3楼，*要改成%，如果是SQLServer数据库，#还要改成\'

或者直接这样替换
Filter = Filter.Replace("*", "%").Replace("#", "\'")

这回舒服多了，多谢各位老师的指点。
