Скачать или смотреть Difference between DELETE, DROP & TRUNCATE in SQL

In SQL, DROP, DELETE, and TRUNCATE are used to manage data, but each serves a different purpose:

1. DROP: Permanently deletes the entire table structure and all its data from the database. It cannot be rolled back and the table needs to be recreated if needed again.


2. DELETE: Removes specific rows from a table based on a condition. It can be rolled back if used within a transaction and does not affect the table structure.


3. TRUNCATE: Quickly removes all rows from a table, resetting it to empty. It's faster than DELETE, but unlike DROP, the table structure remains intact.



Use these commands carefully depending on your data management needs!
