Question

高分求SQL的全部保留字是哪些？

SQL中有些保留字，写SQL的时候经常不知道哪些是保留字，忘记加中括号而导致SQL语句出错，复杂的语句又难找问题。
请高手能不能把全部的保留子都写出来啊！

stockname like '% find this %'
stockname like '[a-zA-Z]%' --------- ([]指定值的范围)
stockname like '[^F-M]%' --------- (^排除指定范围)
--------- 只能在使用like关键字的where子句中使用通配符)
or stockpath = 'stock_path'
or stocknumber < 1000
and stockindex = 24
not stocksex = 'man'
stocknumber between 20 and 100
stocknumber in(10,20,30)

Transact-SQL 参考

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。

ELSE OR WHERE
END ORDER WHILE
ERRLVL OUTER WITH
ESCAPE OVER WRITETEXT

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。有关更多信息，请参见使用标识符。

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。
