Manual methods to restore SQL database without backup

If you are experienced with SQL Server commands, you can try the commands below to restore the deleted SQL database:

  • DBCC CHECKDB (DATABASE_NAME): Check the entire database for repair on the command line or query.
  • REPAIR_ALLOW_DATA_LOSS: Repair data by assigning and releasing rows. (This command removes damaged text, line errors, page and column errors that can lead to data loss.)
  • REPAIR_FAST: Repair the data in a quick process, but only minor changes are made.
  • DBCC CHECKTABLE (TABLE_NAME): Recover a damaged database table from the command line or from the query manager.

Note: This manual way can only be carried out within Microsoft SQL Server Management Studio.

In addition, You can also run MS SQL Server Management Studio in your system and follow the steps below to restore the deleted SQL database:

Step 1. Go to the toolbar and click the “New Query” button.

Step 2. On a new query page, enter the following SQL command:

EXEC sp_resetstatus [DATABASE_NAME];

Step 3. Click “Run” to start the recovery process.

Wait patiently for the process to complete. The longer the process takes, the greater the damage to the server in the database.

So, if the process doesn’t work well, you still need to turn to an automated method or SQL repair tool for help.
