com.github.damiansheldon.jdbc.support.incrementer.MySQLMultipleTableMaxValueIncrementer

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer

public class MySQLMultipleTableMaxValueIncrementer
extends org.springframework.jdbc.support.incrementer.AbstractColumnMaxValueIncrementer

Inspired by MySQLMaxValueIncrementer, support generate primary key for multiple table.

create table tab (id int unsigned not null primary key, text varchar(100));
        create table tab_sequence (tab varchar(255) not null, value int not null);
        insert into tab_sequence values("tab", 0);
