Delete is DML statement which can delete data from table
which needs to be commited afterwards. But it doesn't free
memory area occupied by the data in the table.Where clause
can be used.
Truncate is DDL statement which is auto commit. It not only
deletes all data from table, but it also frees the memory
area occupied the data in the table. where clause is not
permitted. Works faster than delete statement
