[sql]insert ignore into mixups select item from mixrelations where item not in (select id from mixups)[/sql] [sql]delete from mixnoups where id in (select id from mixups)[/sql] Как можно в эти запросах заменить not in на join ? Спасибо!
[sql]insert ignore into mixups select item from mixrelations left join mixups on mixups.id=mixrelations.item where mixups.id is null[/sql] вроде так
