Microsoft SQL Server 2005 使用保留关键字来定义、操作或访问数据库。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 保留关键字。

ADD	EXCEPT	PERCENT
ALL	EXEC	PLAN
ALTER	EXECUTE	PRECISION
AND	EXISTS	PRIMARY
ANY	EXIT	PRINT
AS	FETCH	PROC
ASC	FILE	PROCEDURE
AUTHORIZATION	FILLFACTOR	PUBLIC
BACKUP	FOR	RAISERROR
BEGIN	FOREIGN	READ
BETWEEN	FREETEXT	READTEXT
BREAK	FREETEXTTABLE	RECONFIGURE
BROWSE	FROM	REFERENCES
BULK	FULL	REPLICATION
BY	FUNCTION	RESTORE
CASCADE	GOTO	RESTRICT
CASE	GRANT	RETURN
CHECK	GROUP	REVOKE
CHECKPOINT	HAVING	RIGHT
CLOSE	HOLDLOCK	ROLLBACK
CLUSTERED	IDENTITY	ROWCOUNT
COALESCE	IDENTITY_INSERT	ROWGUIDCOL
COLLATE	IDENTITYCOL	RULE
COLUMN	IF	SAVE
COMMIT	IN	SCHEMA
COMPUTE	INDEX	SELECT
CONSTRAINT	INNER	SESSION_USER
CONTAINS	INSERT	SET
CONTAINSTABLE	INTERSECT	SETUSER
CONTINUE	INTO	SHUTDOWN
CONVERT	IS	SOME
CREATE	JOIN	STATISTICS
CROSS	KEY	SYSTEM_USER
CURRENT	KILL	TABLE
CURRENT_DATE	LEFT	TEXTSIZE
CURRENT_TIME	LIKE	THEN
CURRENT_TIMESTAMP	LINENO	TO
CURRENT_USER	LOAD	TOP
CURSOR	NATIONAL	TRAN
DATABASE	NOCHECK	TRANSACTION
DBCC	NONCLUSTERED	TRIGGER
DEALLOCATE	NOT	TRUNCATE
DECLARE	NULL	TSEQUAL
DEFAULT	NULLIF	UNION
DELETE	OF	UNIQUE
DENY	OFF	UPDATE
DESC	OFFSETS	UPDATETEXT
DISK	ON	USE
DISTINCT	OPEN	USER
DISTRIBUTED	OPENDATASOURCE	VALUES
DOUBLE	OPENQUERY	VARYING
DROP	OPENROWSET	VIEW
DUMMY	OPENXML	WAITFOR
DUMP	OPTION	WHEN
ELSE	OR	WHERE
END	ORDER	WHILE
ERRLVL	OUTER	WITH
ESCAPE	OVER	WRITETEXT

另外，SQL-2003 标准还定义了保留关键字列表。不要使用 SQL-2003 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 SQL-2003 保留关键字列表相同。

注意：

SQL-2003 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-2003 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称。有关详细信息，请参阅使用标识符作为对象名称。

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。
