Deletes all rows of tables present in the specified dataset. If the dataset
does not contains a particular table, but that table exists in the database,
the database table is not affected. Table are truncated in
reverse sequence.
This operation has the same effect of as
TruncateTableOperation .
TruncateTableOperation is faster, and it is non-logged, meaning it cannot be
rollback. DeleteAllOperation is more portable because not all database vendor
support TRUNCATE_TABLE TABLE statement.
