Обсуждение: v7.2 triggers and foreign keys
Hi,
I have two tables a and b.; b references a.
I used pgaccess to create tables.
and psql to create the triggers and foreign keys. a has sequential id, and primary key same column.
As constraints they were implicit, and cascade was off.
On delete of the of a b row, postgres also deleted the a table row.
I then created a2 and b2 with action queries. and the delete acted as expected.
Where am i going wrong with this?
Do I need to install 7.4?
Also, created tables a3 and b3, with sequential ids using pgaccess same as a and b, and the seq id's don't increment with these tables.
Thanks.

You'll need to show the table definitions (with foreign keys etc) and also trigger definitions (use "\d table_a" in psql or "pg_dump --schema-only -t tablename") -- Richard Huxton Archonet Ltd
