ALTER DATABASE a SET EMERGENCY
update sysdatabases set status = 32768 where name = ‘a’
go
use a
go
DBCC checkdb (‘a’, repair_allow_data_loss)

DBCC DROPCLEANBUFFERS

DBCC FREEPROCCACHE

Dbcc REBUILD_LOG (‘a’,’S:\{my path}\MSSQL\Data\a_log.ldf’)

BUT

it gave me this error

On
update sysdatabases set status = 32768 where name = ‘a’

IT GAVE ME THE FOLLOWING ERROR
Ad hoc updates to system catalogs are not allowed

On
use a
AND
DBCC checkdb (‘a’, repair_allow_data_loss)

IT GAVE ME THE FOLLOWING ERROR
Cannot open database ‘a’ version 539. Upgrade the database to the latest version

What should i do ?

Solution 1 it worked fine for me, just is needed add to put the database in single mode before run DBCC.

This error can result from a synchronization problem between replication agents.

to repare, stop replication for the database mentionned in the error and launch sp_replrestart.
