Truncate command is a DDL statement.
DDL ststements can't be rollback. Truncate statement can't be rollback.
In DDL statement we can't use WHERE. In truncate also we can't use WHERE.

DELETE is a DML statement we can rollback as well as we can use WHERE.

Truncate is DDL command, not a DML command
When we issue Truncate on a database table, the records are deleted from the table, and structure remains same. Once we issue truncate on a table, the records will not restored again.
Truncate is a DDL command, and all DDL command by default auto committed. i.e once we apply DDL commands we cannot apply commit or rollback on it. That is the reason Truncate is DDL command.
