FROM (`other_names`)
WHERE  `name`  LIKE '%Dragon Ball Z (U.S.)%'

All i want get is list of unique ids by LIKE.

Answer 1

Replace ‘and second’ with ‘UNION’. 🙂

SELECT `id`
FROM (`videos`)
WHERE  `name`  LIKE '%Dragon Ball Z (U.S.)%' 
UNION
SELECT `vid_id` as id
FROM (`other_names`)
WHERE  `name`  LIKE '%Dragon Ball Z (U.S.)%'

UNION (as opposed to UNION ALL) already returns unique items only, so you won’t need GROUP BY or SELECT DISTINCT. You could write UNION DISTINCT if you think it’s more clear, but you can omit it, since it is the default behaviour of UNION.
