对于 Microsoft Office Access 2007 或 Access 数据库引擎，“保留字”是具有特定含义的单词和符号。如果您使用保留字或符号来命名表中的字段，Access 将向您发出警告，说明该词已保留，并且在引用该字段时您可能会遇到错误。

如果您使用保留字来命名控件、对象或变量，则您也可能会遇到错误。您收到的错误消息不一定会告诉您保留字是导致问题的原因。因此，很难确定需要更改的内容。例如，Access 可能会显示一条与以下类似的消息：

向导无法预览报表，可能因为报表所需的表正被独占锁定。

如果保留字已被使用，您可以用方括号 ([ ])。将每个单词扩起来以避免出现错误消息。但是，最佳解决方案是将名称更改为非保留字。

 注释   提供所有保留字（例如内置函数名称或用户定义的名称）的列表并不现实。如果您设置了对类型库、对象库或 ActiveX 控件的引用，该库的保留字同时也是数据库中的保留字。

Access 数据库引擎保留字

Access 数据库引擎会在不同的模式下运行，这取决于它是从 Access、数据访问对象、Access 数据库引擎的 Microsoft OLE Provider 调用的，还是从 Microsoft Access ODBC 驱动程序调用的。它可以在 ANSI 模式或非 ANSI（传统）模式下运行。

由于使用这两种模式会产生两组略有不同的保留字，因此使用保留字的查询可能在一种模式下能够工作，而在另一种模式下则会失败。

下表列出了在选择标识符名称时应避免使用的保留字。
