    + How can I use the relation table in Query-by-example? +
    + Here is an example with the tables persons, towns and countries. Start + by creating this:

    + +      CREATE TABLE countries (
    +        country_code char(1) NOT NULL default '',
    +        description varchar(10) NOT NULL default '',
    +        PRIMARY KEY (country_code)
    +      ) TYPE=MyISAM;
    +
    +      INSERT INTO countries VALUES ('C', 'Canada');
    +
    +      CREATE TABLE persons (
    +        id tinyint(4) NOT NULL auto_increment,
    +        person_name varchar(32) NOT NULL default '',
    +        town_code varchar(5) default '0',
    +        country_code char(1) NOT NULL default '',
    +        PRIMARY KEY (id)
    +      ) TYPE=MyISAM;
    +
    +      INSERT INTO persons VALUES (11, 'Marc', 'S', '');
    +      INSERT INTO persons VALUES (15, 'Paul', 'S', 'C');
    +
    +      CREATE TABLE relation (
    +        src_table varchar(32) NOT NULL default '',
    +        src_column varchar(32) NOT NULL default '',
    +        dest_table varchar(32) NOT NULL default '',
    +        dest_column varchar(32) NOT NULL default '',
    +        PRIMARY KEY (src_table,src_column)
    +      ) TYPE=MyISAM;
    +
    +      INSERT INTO relation VALUES ('persons', 'town_code', 'towns', 'town_code');
    +      INSERT INTO relation VALUES ('persons', 'country_code', 'countries', 'country_code');
    +
    +      CREATE TABLE towns (
    +        town_code varchar(5) NOT NULL default '0',
    +        description varchar(30) NOT NULL default '',
    +        PRIMARY KEY (town_code)
    +      ) TYPE=MyISAM;
    +
    +      INSERT INTO towns VALUES ('S', 'Sherbrooke');
    +      INSERT INTO towns VALUES ('M', 'Montréal');
    +     +
    + Then test like this: +
