No, it means that you did not specify the whatisness of grandParent, parent, or
child; and/or, you have not enabled foreign_keys.

The statements work. Insertion fails.

Subject: Re: [sqlite] nested
Dear SQLIters,
I am trying to set up what I would call "nested foreign keys":
create grandParent( id PRIMARY KEY)
create parent (id PRIMARY KEY REFERENCES grandParent(id))
___
sqlite-users mailing list
sqlite-users@mailinglists.sqlite.org
These statements worked for me:
CREATE TABLE grandparent (id INTEGER PRIMARY KEY);
CREATE TABLE parent (id INTEGER PRIMARY KEY REFERENCES grandparent(id));
CREATE TABLE child (id INTEGER PRIMARY KEY REFERENCES parent(id));
The foreign key constraints work as you'd expect also.
What are you
Dear SQLiters,
I am trying to set up what I would call "nested foreign keys":
create grandParent (id PRIMARY KEY )
create parent (id PRIMARY KEY REFERENCES grandParent(id))
create child (id PRIMARY KEY REFERENCES parent(id))
SQLite complains. Does it mean that grand children are not allowed?
