MS Sql Server 提供了很多数据库修复的命令,当数据库质疑或是有的无法完成读取时可以尝试这些修复命令。 1. DBCC CHECKDB
重启服务器后,在没有进行任何操作的情况下,在SQL查询分析器中执行以下SQL进行数据库的修复,修复数据库存在的一致性错误与分配错误。
然后执行 DBCC CHECKDB('需要修复的数据库实体的名称') 检查数据库是否仍旧存在错误。注意:修复后可能会造成部分数据的丢失。
2. DBCC CHECKTABLE
如果DBCC CHECKDB 检查仍旧存在错误,可以使用DBCC CHECKTABLE来修复。
3. 其他的一些常用的修复命令
DBCC DBREINDEX 重建指定数据库中表的一个或多个索引
用法:DBCC DBREINDEX (表名,’’) 修复此表所有的索引。
use master declare @databasename varchar(255) set @databasename='需要修复的数据库实体的名称' exec sp_dboption @databasename, N'single', N'true' --将目标数据库置为单用户状态 dbcc checkdb(@databasename,REPAIR_ALLOW_DATA_LOSS) dbcc checkdb(@databasename,REPAIR_REBUILD) exec sp_dboption @databasename, N'single', N'false'--将目标数据库置为多用户状态
use 需要修复的数据库实体的名称 declare @dbname varchar(255) set @dbname='需要修复的数据库实体的名称' exec sp_dboption @dbname,'single user','true' dbcc checktable('需要修复的数据表的名称',REPAIR_ALLOW_DATA_LOSS) dbcc checktable('需要修复的数据表的名称',REPAIR_REBUILD) ------把’ 需要修复的数据表的名称’更改为执行DBCC CHECKDB时报错的数据表的名称 exec sp_dboption @dbname,'single user','false'
