In this way, create a simple data table.
create table country ( id number(2) not null, name varchar(60) not null);create table country_relation (id number(2), parentid number(2));
Insert some data

Simulate tree-like processing of Oracle neighbor models in MySQLDatabases have many processing models for hierarchies. You can design models based on your needs. Of course, the simplest and easiest model to design is the so-called adjacent model. In this regard, other databases, such as Oracle, provide the ready-made analysis method connect by, while MySQL seems a little weak in this regard. However, you can use the MySQL stored procedure to implement similar ORACLE analysis functions.Create tab
