How can you completely delete all records from a database table?

To completely delete all records from a table in a database, the SQL command usually used is:

DELETE FROM table_name;

However, if you need to quickly clear a table and rollback is not important, you can use:

TRUNCATE TABLE table_name;

The difference:

• DELETE removes records row by row and can be rolled back, but is slower.
• TRUNCATE quickly clears the table, resetting data, but usually does not support rollback and does not trigger triggers.

The choice depends on the requirements for transactional integrity and performance.
