使用DBCCDBINFO查询数据库信息
在使用 DBCC DBINFO之前我们先看你下面几个问题: 1. SQL Server是否升级过?安装时的版本是多少? 2. SQL Server当前的内部版本号是多少? 3. SQL Server上次成功运行DBCC CHECKDB的时间是多少? 4. 日志是否被重建过 5. 。。。。。。 上面所需要的信息只需
在使用 DBCC DBINFO之前我们先看你下面几个问题:
1. SQL Server是否升级过?安装时的版本是多少?
2. SQL Server当前的内部版本号是多少?
3. SQL Server上次成功运行DBCC CHECKDB的时间是多少?
4. 日志是否被重建过
5. 。。。。。。
上面所需要的信息只需要一个命令就可以了DBCC DBINFO(这个是Undocumented,但是安全),下面是运行的脚步,为了显示好看我使用了WITH TABLERESULTS
结果如下:
dbi_dbname master
dbi_version 655
dbi_createVersion 611
dbi_dbccLastKnownGood 2011-08-2003:00:05.900
dbi_LastLogBackupTime 1900-01-0100:00:00.000
dbi_RebuildLogs 0
通过上面的信息可以知道我的数据库是从2005升级上去的,在2011年做过DBCCCHECKDB,没做过日志备份,也没重新Rebuild Log.
其实这些信息都是存在数据库的Boot Page里面的,页面ID 9是BootPage,所以上面的信息也可以通过DBCC PAGE 查到。
