SQL語句實(shí)現(xiàn)SQL Server 2000及Sql Server 2005日志收縮(批量)

復(fù)制代碼 代碼如下:

DECLARE @name VARCHAR(25)
DECLARE @SQL VARCHAR(1000)
DECLARE @logid INT

DECLARE sysdatabase_name CURSOR FOR SELECT name FROM master.dbo.sysdatabases

OPEN sysdatabase_name


FETCH NEXT FROM sysdatabase_name INTO @name

WHILE @@FETCH_STATUS = 0
BEGIN

IF ( @name NOT IN ('xxx')) --不需要進(jìn)行日志收縮的數(shù)據(jù)庫名
BEGIN
SET @SQL =' DECLARE @logid INT
USE ' + @name+'
SELECT @logid = fileid FROM sysfiles WHERE RIGHT(rtrim(filename),3) = ''ldf''

BACKUP LOG ' + @name+' WITH NO_LOG
DBCC SHRINKFILE (@logid) '

EXEC(@SQL)

END

FETCH NEXT FROM sysdatabase_name INTO @name

END

CLOSE sysdatabase_name
DEALLOCATE sysdatabase_name
