保留关键字 (Transact-SQL) user 也是，哎

生活随笔收集整理的這篇文章主要介紹了保留关键字 (Transact-SQL) user 也是，哎小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

SQL Server 2005 ?

Microsoft SQL Server 2005 使用保留關鍵字來定義、操作或訪問數據庫。保留關鍵字是 SQL Server 使用的 Transact-SQL 語言語法的一部分，用于分析和理解 Transact-SQL 語句和批處理。盡管在 Transact-SQL 腳本中使用 SQL Server 保留關鍵字作為標識符和對象名在語法上是可行的，但規定只能使用分隔標識符。

下表列出了 SQL Server 保留關鍵字。

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

另外，SQL-2003 標準還定義了保留關鍵字列表。不要使用 SQL-2003 保留關鍵字作為對象名和標識符。 ODBC 保留關鍵字列表（如下表所示）與 SQL-2003 保留關鍵字列表相同。

注意：

SQL-2003 保留關鍵字列表有時可能比 SQL Server 限制更多，有時則限制更少。例如，SQL-2003 保留關鍵字列表包含 INT，而 SQL Server 不需要將其區分為保留關鍵字。

Transact-SQL 保留關鍵字可用作數據庫或數據庫對象（如表、列、視圖等）的標識符或名稱。使用帶引號的標識符或分隔標識符。不限制將保留關鍵字用作變量和存儲過程參數的名稱。有關詳細信息，請參閱使用標識符作為對象名稱。

ODBC 保留關鍵字

保留了下列關鍵字以用于 ODBC 函數調用。這些關鍵字根本不約束 SQL 語法；然而，為確保與支持核心 SQL 語法的驅動程序兼容，應用程序應避免使用這些關鍵字。

下面是當前的 ODBC 保留關鍵字列表。

ABSOLUTE	EXEC	OVERLAPS
ACTION	EXECUTE	PAD
ADA	EXISTS	PARTIAL
ADD	EXTERNAL	PASCAL
ALL	EXTRACT	POSITION
ALLOCATE	FALSE	PRECISION
