Today we will show how to repair corrupted MS SQL database.
In MS SQL Studio run new query:
1. dbcc checkdb(‘DB-NAME’) with no_infomsgs
DB-NAME is a name of your corrupted database. If this is completed without any errors then the database does not need to be repaired.
2. Alter database DB-NAME set SINGLE_USER
Before we begin repairing the database, the database must be set in single user mode.
3. dbcc checkdb(‘DB-NAME’,REPAIR_REBUILD)
There are number of repair model usually we use first REPAIR_REBUILD. When everything is ok go to step 5.e (multi user mode) If not, go to next step.
4. dbcc checkdb(‘DB-NAME’,REPAIR_ALLOW_DATA_LOSS)
This command may cause data loss. When everything is ok go to step 5.e (multi user mode) If not, go to next step.
