DELETE and TRUNCATE are SQL commands for removing data. DELETE targets specific rows, while TRUNCATE removes all rows instantly. Learn their differences here!
DELETE is a DML command that removes selected rows using a WHERE clause. It logs each deletion, allowing rollback before committing changes.
TRUNCATE is a DDL command that deletes all rows in a table instantly. It doesn’t use a WHERE clause and auto-commits changes without logging individual rows.
– DELETE uses row locks; TRUNCATE uses table locks. – DELETE supports rollback; TRUNCATE doesn’t after commit. – DELETE is slower for large datasets; TRUNCATE is faster.
Use DELETE to remove specific rows with conditions or when rollback is needed. Ideal for targeted data removal without affecting table structure.
Use TRUNCATE for clearing all rows in a table quickly, especially for temporary data or archiving purposes where rollback isn’t required.
DELETE allows selective removal and rollback. TRUNCATE is faster but removes all rows without conditions. Choose wisely based on your use case!
