How to recover deleted data in SQL Server

There are several methods to recover deleted data in SQL Server.

1. Using backup files: If a backup was done before deleting data, you can restore the database to the state it was in before the data was deleted.
2. Utilizing the Transaction Log: The transaction log in SQL Server records all operations in the database, including delete operations. The information in the transaction log can be used to recover deleted data by restoring the database to a transaction log backup point prior to the delete operation.
3. Using third-party tools: There are some third-party tools that can help recover deleted data, such as ApexSQL Log, Redgate SQL Log Rescue, etc. These tools can analyze transaction logs, find deleted data, and restore it to the database.

Regardless of the method used, it is important to take recovery measures promptly after deleting data to prevent it from being overwritten or erased, resulting in irretrievable loss.
