Is it possible to completely clear the contents of a table by using the DELETE command, removing all records from it?

The SQL command DELETE allows you to remove all records from a table if no WHERE condition is specified. For example:

DELETE FROM table_name;

This query will delete all rows, but the table structure and its indexes will remain.

However, if you want to completely clear a table and reset associated counters (such as auto-increment), the TRUNCATE TABLE command is often used:

TRUNCATE TABLE table_name;

TRUNCATE works faster and frees space, but it does not support conditions and usually does not trigger triggers.

In summary, DELETE can remove all records, but for a complete table reset and state reset, it is better to use TRUNCATE.
