Hi,
I have an INSERT that looks like
INSERT INTO T
SELECT ...
which I'm running numerous times a second that generally does nothing
because the SELECT returns no rows. Unfortunately, I've found that
SQLite still does numerous disk writes anyway in this situation.
Is my only option to eliminate the INSERT by using a SELECT first to
check if there are no rows? Something like:
CREATE TEMPORARY VIEW V AS
SELECT ...
SELECT COUNT(*) FROM V;
/* If > 0 */
INSERT INTO T SELECT * FROM V;
?
Thanks,
