Subject: No promany key in parent table, how to use delete cascade?
Date: Thu, 07 Nov 2002 23:19:09 -0700
Message-ID: <F1364A2DreBBsQwY6YH00000812@hotmail.com> (raw)

Dear All,

I want to dreate a delete cascade in children tables.  The primary key of 
parent table is oid, so when I create parent table, there is no apparetly 
key word "primary key".  The problem jumps out.

When I create child table using columnn constraint on delete, the SQL says:

"PRIMARY KEY for referenced table "parent" not found"

I do not need to specify the primary key since I am using oid.  How can I 
get around this problem?

Thanks.

Zhidian Du
