数据页故障，索引页故障

use db_tank
dbcc checkdb
--报错如下
由index ID 3可以得知，其为非聚集索引页出了问题

1、初步尝试　　

--切换单用户模式

alter database db_tank
set single_user with rollback IMMEDIATE

dbcc checkdb('db_tank',repair_rebuild) --尝试无损修复

select object_name(477960779) --根据object_id来找到故障对象
use db_tank
select count(1) from db_tank..Sys_Users_Goods where isexist=1 --61364953
dbcc checktable('Sys_Users_Goods',repair_allow_data_loss)

--

alter database db_tank
set multi_user with rollback IMMEDIATE

select * from db_tank_copy..sys_users_goods where itemid = 872981282 dbcc checktable('sys_users_goods',repair_allow_data_loss) -------------- USE master; GO DECLARE @SQL VARCHAR(3000); SET @SQL = ''; SELECT @SQL = @SQL+'; KILL ' + RTRIM(SPID) FROM [sys].[sysprocesses] AS sps WHERE [sps].[dbid] = DB_ID('db_tank'); SET @SQL = SUBSTRING(@SQL, 2, LEN(@SQL)); EXEC(@SQL); GO
