पहले इस क्वेरी को आजमाएं -
SELECT
t.*, ti1.*
FROM
themes t
JOIN theme_images ti1
ON ti1.theme_id = t.theme_id
JOIN (SELECT theme_id, MIN(image_id) image_id FROM theme_images GROUP BY theme_id) ti2
ON ti1.theme_id = ti2.theme_id AND ti1.image_id = ti2.image_id
ORDER BY
t.theme_date_last_modification DESC
LIMIT 10
एक और उपाय -
SELECT
t.*, ti.*
FROM
themes t
JOIN (SELECT * FROM theme_images ORDER BY image_id) ti
ON ti.theme_id = t.theme_id
GROUP BY
theme_id
ORDER BY
t.theme_date_last_modification DESC
LIMIT
10
फिर अपना WHERE फ़िल्टर जोड़ें।
