SQL DROP DATABASE Statement

The DROP DATABASE statement in SQL is used to delete an entire database. This is a powerful and destructive command; it permanently removes the database, including all its tables, data, and associated objects. Always back up your data before using this command.

DROP DATABASE: Definition and Usage

DROP DATABASE is used for completely removing a database. This is typically done when a database is no longer needed or when a database needs to be completely reset. This action cannot be easily undone, so it is essential to have backups if you need to preserve the data.

Syntax

DROP DATABASE database_name;
      

Example
