SQL语句实现SQL Server 2000及Sql Server 2005日志收缩(批量)
代码如下:
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本文来源gao@!dai!ma.com搞$$代^@码网* NOT IN (‘xxx’)) –不需要进行日志收缩的数据库名
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
