In SQLite some constraints are checked per row, not per statement.

We might be - though I assume the OP implicated only deferred
constraints - since immediate constraints will fail on

oblems, (I
tried to find a way to do it myself through the sqlite3 sources but I
couldn't find my way through the virtual machine with the available
documentation).

Before restructuring a database schema always use:
PRAGMA
ed to flag the error, it
doesn't throw a dice to do it.

Thanks for reply !
Thank you for your solution I think it improves the actual situation !

The actual situation is better than nothing but it's still frustrating !

This would not help if that last constraint is no longer violated at the
end of the transaction.

Fair enough !
But even then could it have let's say a place for record the last foreign key
violation ?
Only one place will be better than nothing, it can be overwritten every time
a foreign key is found and at least we could have a message like this:
"FOREIGN KEY constraint failed (x :
Hello !
I know this was discussed here before several times, but it seems that still
we have poor solution for this on sqlite:
FOREIGN KEY constraint failed
I have some databases with lots of foreign keys and I sometimes I need to
change the structure of some tables and I get this message
nothing but it's still frustrating !

No it doesn't, actually. SQLite keeps a counter of FK violations and
resolutions, and if that counter is zero at the the end of the
transaction, then it knows that no FK constraints have failed. If the
counter is
let me know.

Hi all!
I have just recently discovered the strengths of foreign keys but now,
I've been banging my head against the wall for a couple of days.
I just can't figure out what is causing the error or how to get around it.
Here's the specs (simplified) of my DB;
create table if not exists a (id
