What is the Cause of Deletion or Corruption of Table Data?

Corruption or deletion of the table data in SQL Server can be caused due to a myriad of reasons, however, these are the most prominent ones-

This can be caused due to sudden loss of computer power during which work was being done on the SQL Server. This will result in a corrupt database and even a whole deleted database.
2. Software Bugs
In some cases, the SQL Server program itself has internal bugs that interfere with your database files, and thus, cause corruption or deletion.
3. Data Migration
Database files and table records are especially vulnerable at the time of transfer from one server to another. Special care should be taken while transferring the data. Or better yet, it would be wise to use a migration tool to avoid any errors.
4. Malware & Viruses
In the 21st century, viruses are notorious for causing huge damages to organizations in terms of lost or stolen data. Database Administrators are no exception. Malware like the infamous Ransomeware is known to lock away important database files until a “ransom” is paid. Administrators should keep their machines protected.
