Access 2010 SQL：多重条件 Where 子句未正确过滤

Question

我正在尝试为 MS Access 2010 编写一个 SQL 查询到 select 6 个字段的任意组合。我已将 63 种可能的组合写入我的查询中，每个组合都用括号括起来并用 OR 分隔。在内部，每个都由 AND 连接。此外，每个字段都设置为向用户请求参数。

我遇到的问题是，如果我为（示例）字段 A、B 和 C 输入参数，我只会返回 A 和 B 的过滤值，而查询显示不符合参数的项目标准。

代码示例：

`SELECT Main.DISPATCHER, Main.DateCall, Main.Status, Main.[Pick Up 20], Main.[Drop Off 20], Main.Shift, Main.Day, Main.Time, Main.[Call Type], Main.[ETA Given], Main.ZONE, Main.Priority, Main.Comments, Main.DODept, Main.ID, Main.PU, Main.DO, Main.[Pick Up], Main.Caller, Main.DropOff

任何 help/logic 将不胜感激。谢谢

Answer 1

是的，这不是一种非常有效的搜索方式。我的意思是，这个：

OR (Main.Status=[Status: ACCEPTED or DECLINED?])
OR (Main.Status=[Status: ACCEPTED or DECLINED?]
  AND Main.[Pick Up 20]=[What Pick Up?Use Facility List]
  AND Main.[Drop Off 20]=[What Drop Off?-Use Facility List])

在逻辑上等同于：

OR (Main.Status=[Status: ACCEPTED or DECLINED?])

然后在中间你有一堆 AND 语句。

[...]
OR Main.DISPATCHER=[Which Dispatcher?Ex Justin]
AND Main.DateCall BETWEEN [Enter Start Date:] AND [Enter Ending Date:]
AND Main.Status=[Status: ACCEPTED or DECLINED?]
AND Main.Shift=[What shift?AM/PM]
OR [...]

这将基本上覆盖您拥有的所有其他内容。全部这些条件都得满足

假设当您不提交字段时提示的值为NULL。我们还假设您必须提交通话日期范围内的两个日期。要进行完整搜索，您可以这样做：

WHERE (Main.DISPATCHER=[Which Dispatcher?Ex Justin] OR [Which Dispatcher?Ex Justin] IS NULL)
    AND (Main.DateCall BETWEEN [Enter Start Date:] AND [Enter Ending Date:] OR [Enter Start Date:] IS NULL OR [Enter Ending Date:] IS NULL)
    AND (Main.Status=[Status: ACCEPTED or DECLINED?] OR [Status: ACCEPTED or DECLINED?] IS NULL)
    AND (Main.[Pick Up 20]=[What Pick Up?Use Facility List] OR [What Pick Up?Use Facility List] IS NULL)
    AND (Main.[Drop Off 20]=[What Drop Off?-Use Facility List] OR [What Drop Off?-Use Facility List] IS NULL)
    AND (Main.Shift=[What shift?AM/PM] OR [What shift?AM/PM] IS NULL)
