If the SQL Server database contains the minimum level of corruption and one can easily repair the corrupted with the Database console commands or DBCC.

When the user executes the DBCC command then the database engine creates the snapshot and brings the database in a consistent state. Sometimes the snapshot of the database is not available then in such cases the DBCC commands run the against the live server. If the corruption is due to the table then try to run the command

 DBCC Checktable (‘table_name’)

This command checks the integrity of all the pages and the structure associated with the table or the indexed view

The Syntax for the DBCC Checktable to Recover SQL Server Database Without Backup

 DBCC CHECKTABLE
 (
 table_name | view_name
 [ , { NOINDEX | index_id }
 |, { REPAIR_ALLOW_DATA_LOSS | REPAIR_FAST | REPAIR_REBUILD }
 ]
 )
 [ WITH
 { ALL_ERRORMSGS ]
 [ , EXTENDED_LOGICAL_CHECKS ]
 [ , NO_INFOMSGS ]
 [ , TABLOCK ]
 [ , ESTIMATEONLY ]
 [ , { PHYSICAL_ONLY | DATA_PURITY } ]
 [ , MAXDOP = number_of_processors ]
 }
 ]

If the corruption in the database still persist then in such case you need to run the DBCC Checkdb command with following attributes

 REPAIR_ALLOW_DATA_LOSS | REPAIR_FAST | REPAIR_REBUILD

The complete syntax of the command will be like this

DBCC CHECKDB
 [ ( database_name | database_id | 0
 [ , NOINDEX
 | , { REPAIR_ALLOW_DATA_LOSS | REPAIR_FAST | REPAIR_REBUILD } ]
 ) ]
 [ WITH
 {
 [ ALL_ERRORMSGS ]
 [ , EXTENDED_LOGICAL_CHECKS ]
 [ , NO_INFOMSGS ]
 [ , TABLOCK ]
 [ , ESTIMATEONLY ]
 [ , { PHYSICAL_ONLY | DATA_PURITY } ]
 [ , MAXDOP = number_of_processors ]
 }
 ]
 ]

But there are certain things you need to remember and taken care off such as:

1. The specified database must be in the single-user mode
2. Before attempting this method, please create the physical copies of the files associated with a database such as primary data file or .mdf, secondary data file or .ndf and complete transaction log files etc.
3. Ensure that the database state of the database is in emergency mode.

Limitations of Manual Solution 

There are certain limitations also associated with the manual solution. Some of them are:

1. REPAIR_ALLOW_DATA_LOSS | REPAIR_FAST | is not a good alternative to the recovery of the database from the well-known backup. But this can be used only as of the last or emergency resort when there is no fresh backup is available to recover data. These commands are highly supported but not considered as the best option to bring the SQL Server database to a consistent state. Because the successful execution of this command will also result in loss of data.
2. DBCC CHECKDB does not examine any disable index.
3. It does not ensure ACID properties any transaction
