difference between truncate and delete

1.truncate removes rows in one execution..delete removes
rows one by one so truncate is fast..

2.truncate does not creates logs and hence canot be
rolledback and hence is a DDL stmt..DELETE creates rollback
segment hence can be rolled back and hence is a DML stmt.

3.truncate doesnot allow for conditional remove of records
(all records has to remove) DELETE allows conditonal remove
of records(where cluase etc can be used.)

4.triggers are not fired on truncate stmt but trgieers are
fired on DELETE stmt..

Answer / satya_k21

Hi,

By using truncate command we can delete all the records
in a table , but we cant delete a single record in a table.

by using delete command we can delete a entire records
or a specified record in a table..
Delete is a DML Operation but truncate is DDL Operation
let me know if it is wrong.

Regards,
Satya.k
