检查SQL Server事务日志大小

2006年08月24日 14:15:00

最近开始接手SQL Server数据库管理了，每天都要一个一个检查事务日志大小。于是请同事写了一个检查事务日志大小的SQL脚本，列出事务日志超过1G的数据库，顺便也学习学习，自从转入运维后就很少接触SQL了，现在又要拾起来了。

set nocount on

declare @name sysname
declare @SQL nvarchar(600)

create table #databases (
DATABASE_ID int NOT NULL,
size int NOT NULL)

declare c1 cursor for
select name from master.dbo.sysdatabases
where has_dbaccess(name) = 1

open c1
fetch c1 into @name

while @@fetch_status <= 0
begin
select @SQL = 'insert into #databases
select '+ convert(sysname, db_id(@name)) + ', size from '
+ QuoteName(@name) + '.dbo.sysfiles where fileid=2 '
execute (@SQL)
fetch c1 into @name
end

deallocate c1

select
DATABASE_NAME = db_name(DATABASE_ID),
LOG_SIZE = cast(round((CEILING(size*8/1024)+1)/1024,3) as varchar(20))+' G' --(G)
from #databases
where db_name(DATABASE_ID) not in ('master','model','msdb','pubs','Northwind','tempdb')
and round((CEILING(size*8/1024)+1)/1024,3) <= 1
order by 1

drop table #databases
