 此外，ISO 标准定义了保留关键字列表。 不要使用 ISO 保留关键字作为对象名和标识符。 ODBC 保留关键字列表（如下表所示）与 ISO 保留关键字列表相同。

注意

ISO 标准保留关键字有时可能比 SQL Server 限制更多，有时则更少。 例如，ISO 保留关键字列表包含 INT。 SQL Server 不必将此区分为保留关键字。

Transact-SQL 保留关键字可用作数据库或数据库对象（如表、列、视图等）的标识符或名称。 使用带引号的标识符或分隔标识符。 不限制将保留关键字用作变量和存储过程参数的名

ODBC 保留关键字

保留了下列关键字以用于 ODBC 函数调用。这些关键字根本不约束 SQL 语法；然而，为确保与支持核心 SQL 语法的驱动程序兼容，应用程序应避免使用这些关键字。

下面是当前的 ODBC 保留关键字列表。
