TRUNCATE -- Empty a table
TRUNCATE [ TABLE ] name
The name of the table to be truncated.
Message returned if the table is successfully
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 effective on large tables.
Truncate the table bigtable:
TRUNCATE TABLE bigtable;
There is no TRUNCATE in SQL92.
