Didn't get your humor here ;-)
But please answer a question: can we somehow create relationship where we can
provide args in runtime, so this is possible:
3 COALESCE(t2.lang, t1.lang) AS lang,
4 COALESCE(t2.title, t1.title) AS title,
5 COALESCE(t2.body, t1.body) AS body,
7 entry AS t1
8 LEFT JOIN
9 entry_t AS t2
11 t1.id = t2.transof AND t2.lang = 'ru'
12 ORDER BY
14 LIMIT 5
Question is about line #11 and ``AND t2.lang = 'ru'".
