“保留字”是对 Microsoft Access 有特殊含义的单词和符号。 如果使用保留字或符号来命名桌面数据库或 Web 应用表中的字段,Access 会警告提示该字是保留字,且在引用该字段时可能会遇到错误。

如果使用保留字来命名控件、对象或变量,也可能遇到错误。 你收到的错误消息不一定会告诉你保留字是导致问题的原因。 因此,可能很难确定需要更改哪些内容。 例如,Access 可能会显示一条消息,类似于:

向导无法预览报表,可能是因为以独占方式锁定了报表所需的表。

如果已在使用保留字,可用方括号 ([]) 将每次出现的保留字括起来,从而避免错误消息。 但是,最好的解决方案是将名称更改为非保留字。

注意:  提供所有保留字的列表(如内置函数名或用户定义的名称)并不可行。 如果设置了类型库、对象库或 ActiveX 控件的引用,则该库的保留字也是数据库中的保留字。

Access​​ 数据库引擎保留字

Access 数据库引擎以不同的模式运行,具体取决于调用位置:从 Access、数据访问对象、用于 Access 数据库引擎的 Microsoft OLE 提供程序还是从 Microsoft Access ODBC 驱动程序。 它可在 ANSI 模式或非 ANSI(传统)模式下运行。

由于使用这两种模式时两个保留字集也稍有不同,因此使用某个保留字的查询可能在一种模式中正常,但在另一种模式中失败。

以下是在选择标识符名称时要避免的保留字列表。
