SQLITE_LOCKED is an immediate return (that is, it returns immediately, it is
not subject to automatic retries or timeouts or the busy/wait handler -- it is
an error indication, not necessarily a transient condition).
You may use the sqlite3_unlock_notify API (assuming that you have compiled
(For those playing along at home, SQLITE_LOCKED is a special-case version of
SQLITE_BUSY. You get it only when the competing access attempts come from the
same connection (multi-tasking) or different connections sharing the same
cache.)

No. I've not part of the development team but I think it's quite complicated.
Also, the fact that there's already a function which does what you want makes
it unlikely
A manual INSERT demonstrates the same behavior, actually. Using your Tc
table:
sqlite> insert into Tc values ('12');
Error: CHECK constraint failed: Tc
The thing about .import is that, instead of guessing what type each value
it reads is, they're all just bound to an insert statement as strings.
Hi Simon,
Thanks! Indeed I thought about a similar solution but it seems a little
contrived.
Do you think it would be possible to add a function that does what I need?
How is the design coordinated? Where should I post my RFC?
Cheers,
Simone

It's not simple but if you are actually trying to execute that statement, you
can register an authorizer function.
Hi All,
I am already afraid that the answer to the question will be "no", but it
will save a lot of development effort on my side, so is worth to ask.
Given a statement, is there any way to know if it is an UPDATE, DELETE,
INSERT, SELECT or something else?
Thanks,
Simone

Wow! Thanks. I did not know these choices. Now I do. ;-)

Greetings.
I have this table,
create table a (a, b, c);
insert into a values (1, 2, 3);
insert into a values (2, 3, 4);
insert into a values (3, 4, 5);
insert into a values (4, 5, 6);
insert into a values (5, 6, 7);
insert into a values (6, 7, 8);
and I also have this table,
create
That's the error I got too. Now fixed here:
