PersistentObject: ezcPersistentNativeGenerator

[ Tutorial ] [ Class tree ] [ Element index ] [ ChangeLog ] [ Credits ]

Class: ezcPersistentNativeGenerator

Generates IDs based on the PDO::lastInsertId method. [source]
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 ));
