Handling of SQL database labeled as suspicious/questioning

In the manager, the database is marked as suspicious (in the original version 2000, it seems to be "suspicious"), and no operation can be performed on the database. Use the following SQL:

Db1 indicates the database name.

Code
USE MASTER
GO
SP_CONFIGURE 'Allow updates', 1 RECONFIGURE WITH OVERRIDE
GO
Alter database db1 SET EMERGENCY
GO
Sp_dboption 'db1', 'single user', 'true'
GO
Dbcc checkdb ('db1', 'repair _ ALLOW_DATA_LOSS ')
GO
Alter database db1 SET ONLINE
GO
Sp_configure 'Allow updates', 0 reconfigure with override
GO
Sp_dboption 'db1', 'single user', 'false'
GO
