PersistentObject::ezcPersistentSequenceGenerator
Class ezcPersistentSequenceGenerator
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. Use ezcPersistentNativeGenerator for those!
For none auto_increment databases:
- CREATE TABLE test ( id integer unsigned not null, PRIMARY KEY (id ));
- CREATE SEQUENCE test_seq START 1;
This class reads the parameters:
- sequence - The name of the database sequence keeping track of the ID. This field should be ommited for databases supporting auto_increment.
