PersistentObject::ezcPersistentNativeGenerator

Class ezcPersistentNativeGenerator

Generates IDs based on the PDO::lastInsertId method.

It is recommended to use auto_increment id columns for databases supporting it. This includes MySQL and SQLite. Other databases need to create a sequence per table.

auto_increment databases:

  1.   CREATE TABLE test
  2.   ( id integer unsigned not null auto_increment, PRIMARY KEY (id ));
