Answer Posted / mohammed
DROP and TRUNCATE are DDL commands, whereas DELETE is a DML
command. Therefore DELETE operations can be rolled back
(undone), while DROP and TRUNCATE operations cannot be
rolled back.It is possible to delete all rows in a table
without deleting the table. This means that the table
structure, attributes, and indexes will be intact.Indexes,
tables, and databases can easily be deleted/removed with
the DROP statement. If we only want to delete the data
inside the table, and not the table itself....
Then, use the TRUNCATE TABLE statement.
