CREATE TABLE `user` (
  `iduser`  int(10) unsigned NOT NULL auto_increment,
  `name`    varchar(40) default NULL,
  PRIMARY KEY  (`iduser`),
  INDEX `name` (`name`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;

CREATE TABLE `book` (
  `idbook` int(10) unsigned NOT NULL auto_increment,
  `name`   int(10) unsigned default NULL,
  PRIMARY KEY  (`idbook`),
  INDEX `iduser` (`name`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;

CREATE TABLE `owned` (
  `idowned` int(10) unsigned NOT NULL auto_increment,
  `idbook` int(10) unsigned default NULL,
  `iduser`   int(10) unsigned default NULL,
  PRIMARY KEY  (`idbook`),
  INDEX `iduser` (`iduser`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;

INSERT INTO book ... -- nova knizka
INSERT INTO user ... -- novy uzivatel
INSERT INTO owned ... -- knizka1 pujcena uzivateli
INSERT INTO owned ... -- knizka2 pujcena uzivateli
INSERT INTO owned ... -- knizka3 pujcena uzivateli

SELECT a.iduser, a.idbook, b.name, c.name -- vyber knih pujcenych uzivatelem
FROM owned a
LEFT JOIN user b ON b.iduser = a.iduser
LEFT JOIN user c ON c.idbook = a.idbook
WHERE a.iduser=123

Napis z toho program, dej link na kod (asi jako txt soubor) v poznamce mej i create table a pak se da bavit o necem konkretnim, co si muzu u sebe spustit, vytvorit tabulky v db...

on chcel many to one a nie many to many ... a ked uz chces robit many to many tak by bolo logickejsie dat tabulky person, book (actual book), bookMeta (author, isbn, version ...)
