do you mean that you have a primary key on table a with an fk to table b? and on table b you have a primary key and an fk to table a? if so, you've created a circular referential integrity constraint. The table deadlocks since the values must exist in the other (tables a and b) table. There are several solutions: 1. if the db supports it, use deferred constraints (check the docs) 2. remove one of the FK constraints from one of the tables Bastien > From: thiago.pojda@xxxxxxxxxxxxxxxxxx> To: nasreen_laghari@xxxxxxxxx; php-db@xxxxxxxxxxxxx> Date: Tue, 26 Feb 2008 09:17:30 -0300> Subject: RES: [PHP-DB] INSERT query with Primary and foreign key> > This is more SQL than PHP, how did you create your constraints?> > Did you set insert on CASCADE?> > -----Mensagem original-----> De: Nasreen Laghari [mailto:nasreen_laghari@xxxxxxxxx] > Enviada em: segunda-feira, 25 de fevereiro de 2008 22:15> Para: php-db@xxxxxxxxxxxxx> Assunto: INSERT query with Primary and foreign key> > Hi,> > I need help to insert date into two tables when tables have primary and> foreign key relationship using php.
