Question

我正在尝试为MS Access 2010编写SQL查询以选择6个字段的任意组合。我已经将63种可能的组合写入了我的查询中，每种组合都被括起来并用OR分隔。在内部，每个都由AND连接。此外，每个字段被设置为从用户请求参数。

我遇到的问题是，如果我输入（示例）字段A，B和C的参数，我只返回A和B的过滤值，而查询显示不符合参数条件的项。

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

非常感谢任何帮助/逻辑。感谢。

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])

在逻辑上等同于此：

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 [...]

这基本上会覆盖你所拥有的其他一切。所有必须满足这些条件。

我们假设当您未提交字段时，提示值为NULL。我们还假设您必须提交通话日期范围的两个日期。要进行完整搜索，您可以执行以下操作：

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)
