Sie können so etwas tun:
SELECT
t1.post_id,
t1.meta_value AS name,
t2.meta_value AS season,
t3.meta_value AS episode
FROM
(
SELECT *
FROM the_table
WHERE meta_key = 'name'
) t1
INNER JOIN
(
SELECT *
FROM the_table
WHERE meta_key = 'season'
) t2 ON t1.post_id = t2.post_id
INNER JOIN
(
SELECT *
FROM the_table
WHERE meta_key = 'episode'
) t3 ON t1.post_id = t3.post_id
Dadurch erhalten Sie das Ergebnis:
| post_id | name | season | episode |
-------------------------------------------
| 1 | Smallville | 1 | 1 |
| 2 | Smallville | 1 | 2 |
In dieser Form ist es viel einfacher für alle Operationen.
Was Sie hinzufügen müssen, ist:
WHERE name = 'Smallville'
ORDER BY season, episode
