Question

I have the following query

SELECT
    interview_content.title `title`,
    gallery_images.img_path img
FROM
    `interview`,
    `interview_content`,
    `gallery`,
    `gallery_images`
WHERE
    `gallery_images`.`id_parrent` = `gallery`.`id`
AND
    `gallery`.`id` =  `interview`.`gallery_id`
AND
    `gallery_images`.`default` = '1'
AND
    `interview`.`id` = `interview_content`.`id_parrent`
AND
    interview_content.id_lang = '2'
ORDER BY
    interview.date DESC

I need to use LEFT JOIN on gallery, gallery_images tables (to be able to get interview.title even when there is no gallery or default image)

Thanks much

UPDATE

The problem, is in second LEFT JOIN. I can’t make them to work together correctly. When i try

SELECT
    interview_content.title `title`,
    gi.img_path img
FROM
    `interview`,
    `interview_content`
LEFT JOIN `gallery` as g ON g.`id` = `interview`.`gallery_id` 
LEFT JOIN `gallery_images` as gi ON gi.id_parrent = g.`id`
WHERE
    `interview`.`id` = `interview_content`.`id_parrent`
AND
    interview_content.id_lang = '2'
ORDER BY
    interview.date DESC

it returns //Unknown column 'interview.gallery_id' in 'on clause'

Answer 1

Don’t mix ANSI-89 style and ANSI-92 style joins.

I found same question in SO, here.

So my query must look like this

SELECT
    ic.title `title`,
    gi.img_path img
FROM
    `interview` i
JOIN interview_content ic  on ic.id_parrent =  i.id AND ic.id_lang = '2'
LEFT JOIN `gallery` as g ON g.`id` = i.`gallery_id` 
LEFT JOIN `gallery_images` as gi ON gi.id_parrent = g.`id`
AND gi.`default` = '1'
WHERE
    i.`id` = ic.`id_parrent`
OPRDER BY
    `i`.`date` DESC
