Thank you. I have changed chromium's copy of sqlite to contain the above
version of the code, so we're closer to upstream now.

Hi
I have a table that contains 6 columns of integers, 2 of these columns
are indexed. There are about 10 Million rows of data in the table.
every now and again I need to add more rows, between about a thousand
and a million at a time. I want the process to be as quiick as
possible (although I kno
If the database is corrupted, then this is really bad. If you don't have a
backup of your file, then it's almost not really possible to repair the
database. As far as I know...
You could open the database in an editor and try to pick some data, that
was left in the database.

Michael,
In this particular instance my questions were posed rhetorically to the OP
after I had given his trigger a little more thought. But I can be lazy, for
sure, so if you don't mind I'll keep your rebuke ready to hand for the next
time it's deserved, which should be soon as it's hot and humid
You could've tested this in the time it took for you to get answer:
File x.sql
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE t (i integer);
INSERT INTO "t" VALUES(1);
CREATE TABLE c(i integer);
CREATE TRIGGER t1 before insert on t begin insert into c values((select
count(*) from t));e

Is a to-be-inserted row supposed to be included among the counted rows in a
BEFORE INSERT trigger? Could you end up with 5 rows? What happens if you
make this an AFTER trigger?

Could your trigger be running into the syntax restriction described below?
I'm not sure if the restriction actually applies to your circumstance -- not
sure whether LIMIT and ORDER BY are invalid *anywhere* in a statement in a
trigger that deletes a row, i.e. invalid also in a subquery, as you have

Dear sqlite developers,
I have noticed that the .dump command quotes the table name on INSERT
commands, but does not quote them on CREATE TABLE commands.
Import operations using the generated SQL into Postgresql fails unless one
manually edits the SQL to quote mixed case or upper case table names
