   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;
