Hi,

I need help to insert date into two tables when tables have primary and foreign key relationship using php. I tried simple INSERT query but foreign key colum is storing NULL.

Regards

Nasreen

This is more SQL than PHP, how did you create your constraints?

Did you set insert on CASCADE?

do you mean that you have a primary key on table a with an fk to table b? a=
nd 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 tabl=
e 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

What's your SQL query string, Nasreen?
