Fixed. See http://www.sqlite.org/src/info/dd08e5a988 and
Looks like the same suggestion as DRH already provided applies here:
your indexes on (childID, fatherID) and (childID, motherID) are
useless. You already have unique childID, adding fatherID or matherID
to it doesn't change things. Also any other table can reference only
childID, there's no need
Thanks for your quick answer!
I was trying to provide a simple example.
Here is another example to demonstrate the problem.
I am using a lot "surrogate key with propagation",
and this is why I have many composite foreign keys.
PRAGMA foreign_keys = ON;
CREATE TABLE parent(
parentID

Hello,
It seems that composite FK are not enforced on SQLite 3.6.23.1.
The following script shows that the DELETE FROM table "artist" will work, even
though
there is a composite FK from table "track" toward table "artist".
PRAGMA foreign_keys = ON;
CREATE TABLE artist(
artistidINTEGER
