Overview: Microsoft SQL has made its identity these days and it is mostly used as a database management system. Users have important data there and it’s very simple to create a backup and restore the data files in the time of urgency. We have heard many cases where the users have accidentally dropped the Database, and they want to recover SQL data from a dropped table without backup.
It is necessary to recover SQL because there are several parts of the SQL server. It can be affected by data loss like a relational database, client/server, Database file, and Database Management system that manages all these parts. This database file is quite a complex and organized file that manages the data. Therefore, it plays a principal role. Relational Database is the method, the data is organized that is in the form of tables. The server system or the client works as the prime communicator and the users which are on the multiple client machines that are connected to the server accessed by a machine from a Local Area Network.
There can be several reasons which lead to data loss and users have to recover them. Let’s see a few of them
Reasons by which Users Need to Recover SQL Server Database without Backup
Sometimes the files get damaged or corrupted due to any reason
When the file of the system get corrupted
There’s also a situation when there is a failure in the Storage device
There can be various other reasons for the data loss. But these three are the main reasons. There are methods or solutions which help you in SQL data recovery. If the data loss occurred to the file, then the possibilities are low because of the complex nature of the files. If the problem is with the file system, then the system requires to get repaired. It can sometimes get automatically if the OS supports such a function. However, if there is a failure in the storage system, then most probably this issue is the hard disk’s issue. Try to find the method to make it work to recover the data
Method to Recover SQL Data from a Dropped Table Without Backup
Restoring the lost data is not a big problem if you have the backup. Here are some commands which help you to recover SQL Server database without backup.
DBCC CHECKDB (DATABASE_NAME): You have to check the entire database for restore in the command line or query manager
REPAIR_ALLOW_DATA_LOSS: Use this command to restore the data with the help of the allocation and deallocation of rows. It also removes the damaged or corrupted text, row errors, column errors, and page error. It can sound easy but is a very complex procedure and has a risk of data loss during SQL data recovery
REPAIR_FAST: This command is used for restoring procedures. As the name suggests it takes less time to restore the data, but it only can make minor changes
DBCC CHECKTABLE (TABLE_NAME): This command used in the command line or query manager to repair the corrupt database table
Both commands can only be executed if you have Microsoft SQL Server Management Studio. And for that, you need to open the system and follow the given steps to recover deleted SQL database:
Go to the Toolbar and Hit on New Query button
Then go to a new query page
Now, enter the following SQL script
EXEC sp_resetstatus [DATABASE_NAME]
ALTER DATABASE [DATABASE_NAME] SET EMERGENCY
DBCC CHECKDB ([DATABASE_NAME])
ALTER DATABASE [DATABASE_NAME] SET SINGLE_USER WITH ROLLBACK INSTANT
DBCC DATABASE ([DATABASE_NAME], REAPIR_ALLOW_DATA_LOSS)
ALTER DATABASE [DATABASE_NAME] SET MULTI_USER
Now, tap on Execute to start the repair
By using this method you can know how to recover deleted data from a table in SQL server under the guidance of a professional.
Conclusion
SQL Databases always plays an important role and recovering is the most important. In this blog, we have just discussed the method to recover SQL data from a dropped table without backup. By following the above method you can easily recover the SQL database. One should follow the steps concentrated because of the SQL script.
