Description
TRUNCATE quickly removes all rows from a
table. It has the same effect as an unqualified
DELETE but since it does not actually scan the
table it is faster. This is most useful on large tables.
TRUNCATE cannot be executed inside a transaction
block (BEGIN>/COMMIT> pair), because there is
no way to roll it back.
Usage
Truncate the table bigtable:
TRUNCATE TABLE bigtable;
