What is Difference Between delete and Truncate?..

Answer / nandini sett

Both delete and Trunate are DML or Data Manupilating
Language.
Both statements --- Delete table_name and Truncate table
table_name --- deletes all rows.
Truncate Table works faster than delete.
Truncate table does not support where clause and truncate
doe not fire a trigger. When truncate is used the deleted
rows are not entered in transaction log.

Answer / rajesh

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
