Mysql JOIN和WHERE问题

Question

有人可以帮我解决这个问题吗？

SELECT a.filename AS thumbpath, b.filename AS imagepath, name 
FROM gallerythumbs AS a WHERE gallery = 1 
JOIN galleryimages AS b 
USING(id) ORDER BY id DESC 
LIMIT $start, $per_page 

我有3个画廊的数据被添加到msqyl表。每个画廊都会将1，2或3放入画廊字段中。

我在哪里，就把这行

WHERE gallery = 1 

感谢您寻找

WHERE走后FROM（毕竟JOIN S）

FROM 
    gallerythumbs AS a 
    JOIN galleryimages AS b USING (id) 
WHERE 
    gallery = 1 

USING(id)在这种情况下可能不正确。您可能想使用类似ON (a.id = b.galleryid)的东西。
