Hi! I have two tables: CREATE TABLE `pokoje` ( `nrpok_p` char(10) NOT NULL default '', `nip_h` int(10) NOT NULL default '0', `lozka_p` char(2) default NULL, `tv_p` char(1) default NULL, `lazienka_p` char(1) default NULL, `cena_p` int(10) default NULL, `zaliczka_p` int(10) default NULL, PRIMARY KEY (`nrpok_p`,`nip_h`), KEY `nip_h_index` (`nip_h`,`nrpok_p`), FOREIGN KEY (`nip_h`) REFERENCES `hotele` (`nip_h`) ON DELETE CASCADE ) TYPE=InnoDB;
CREATE TABLE `rezerwacje` ( `id_r` int(10) NOT NULL default '0', `pesel_k` int(11) default NULL, `nip_h` int(10) NOT NULL default '0', `nrpok_p` char(10) NOT NULL default '', `data_r` date default NULL, `od_r` date default NULL, `do_r` date default NULL, `cena_r` int(10) default NULL, `zaliczka_r` int(5) default NULL, `zaplac_r` char(1) default NULL, `wplaczal_r` char(1) default NULL, PRIMARY KEY (`id_r`), KEY `nip_h_index` (`nip_h`,`nrpok_p`) ) TYPE=InnoDB; Now, when I try: alter table rezerwacje add foreign key (nip_h,nrpok_p) references pokoje(nip_h,nrpok_p); I get: ERROR 1005: Can't create table './test/#sql-932_4.frm' (errno: 150) Why? -- _/ _/ _/_/_/ ----- Rafał Jank [EMAIL PROTECTED] ----- _/ _/ _/ _/ _/ Wirtualna Polska SA http://www.wp.pl _/_/_/_/ _/_/_/ ul.
