左JOIN語法錯誤

Question

我收到此查詢systax錯誤。

SELECT 
    e.post_id as id, e.start as start_date, 
    p.post_title, 
    c.name as category 
FROM 
    wp_ai1ec_events as e LEFT_JOIN wp_term_relationships as t ON e.post_id = t.object_id 
    LEFT_JOIN wp_term_relationships as t ON e.post_id = t.object_id 
    LEFT_JOIN wp_terms as c ON c.term_id = t.term_taxonomy_id 
    LEFT_JOIN wp_posts as p ON p.ID = e.post_id 
GROUP BY e.post_id 

其實我可能甚至不需要左連接在這種情況下，因爲所有要重視一個行...

Error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LEFT_JOIN wp_term_relationships as t ON e.post_id = t.object_id LEFT_JOIN w' at line 6 

任何幫助，將不勝感激。謝謝。

Answer 1

有一個在LEFT JOIN

LEFT_JOIN無底線應該是LEFT JOIN
