(this may also be the case in mysql, when using a transactional storage engine.) typically, truncate table quickly deletes all records in a table by deallocating the data pages used by the table. [1] data truncation may occur automatically, such as when a long string is written to a smaller buffer, or deliberately, when only a portion of the data is wanted Truncate deletes all data from a table in a very fast way, deleting the data inside the table and not the table itself
