如何使用组合框中的所有值的条件进行查询？

问题描述

我正在为当地教会制作一个目录数据库。他们跟踪成员和非成员。目前我有一个组合框设置作为查询的条件，列出成员或非成员（组合框中的两个选项）。是否有办法使相同的组合框具有全部组合。选项，以便列出数据库中的每个人？这样，用户可以选择搜索所有成员，所有非成员或所有人（成员和非成员）全部来自同一个组合框。

I''m making a directory database for a local church. They keep track of members as well as non-members. Currently I have a combobox set as the criteria for a query to list either the members or the non-members (the two options in the combobox). Is there a way to make it so that the same combobox will have an "all" option so that everyone in the database will be listed? That way the user has the option to search for all members, all non-members, or everyone (members and non-members) all out of the same combobox.
