Ib yam li ntawd, kuv yuav kho kuv cov ntaub ntawv li cas hauv hom xwm txheej ceev?
Txhawm rau hloov cov xwm txheej database rau hom xwm txheej kub ntxhov, khiav cov lus nug hauv qab T-SQL:
- ALTER DATABASE dbName SET EMERGENCY.
- DBCC CHECKDB('dbName')
- ALTER DATABASE dbName SET SINGLE_USER nrog ROLLBACK tam sim ntawd.
- DBCC CHECKDB (dbName, REPAIR_ALLOW_DATA_LOS)
