DELETE
TRUNCATE
Difference The most important difference is DELETE operations are transaction-safe and logged, which means DELETE can be rolled back. TRUNCATE cannot be done inside a transaction and can’t be rolled back. Because TRUNCATE is not logged recovering a mistakenly TRUNCATEd table is a much bigger problem than recovering from a DELETE.
DELETE will fail if foreign key constraints are broken; TRUNCATE may not honor foreign key constraints (it does for InnoDB tables). DELETE will fire any ON DELETE triggers; TRUNCATE will not.
