sql server的保留关键字_[SQL Server教程]

SQL Server 保留关键字
Microsoft SQL Server 2000 使用保留关键字定义、操作和访问数据库。保留关键字是 SQL Server 使用的 Transact-SQL 语言语法的一部分，用于分析和理解 Transact-SQL 语句和批处理。尽管在 Transact-SQL 脚本中，使用 SQL Server 保留关键字作为标识符和对象名在语法上是可行的，但规定只能使用分隔标识符。
下表列出了 SQL Server 的保留关键字。

另外，SQL-92 标准还定义了保留关键字列表。不要使用 SQL-92 保留关键字作为对象名和标识符。ODBC 保留关键字列表（如下所示）与 SQL-92 保留关键字列表相同。
说明??SQL-92 保留关键字列表有时可能比 SQL Server 限制更多，有时则限制更少。例如，SQL-92 保留关键字列表包含 INT，而 SQL Server 不需要将其区分为保留关键字。
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。使用被引用的标识符或分隔标识符。对将保留关键字用作变量和存储过程参数的名称没有限制。
ODBC 保留关键字
保留了下列关键字用于 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。有关更多信息，请参见《Microsoft ODBC 3.0 程序员参考》，第 2 卷，附录 C。
