mysql - 我可以在加入 2 个表后添加 AND 吗？

Question

这是一个合法的 MySql 查询吗？（更准确地说，是我加入 2 个表并添加 AND 条件的部分。）

LEFT JOIN release_artwork ON release_artwork.album_id = album.album_id AND release_artwork.position = 1

这是完整的查询：

SELECT album.album_id, album.title, country.country_id, artwork.thumb_filename, artwork.thumb_width, artwork.thumb_height
FROM song
JOIN album ON song.published_album = album.album_id
LEFT JOIN country ON album.country_id = country.country_id
LEFT JOIN release_artwork ON release_artwork.release_id = album.album_id AND release_artwork.position = 1
LEFT JOIN artwork ON artwork.artwork_id = release_artwork.artwork_id
WHERE song.song_id = 1

我可以AND在加入 2 个表后立即添加吗？

Answer 1

这是完全合法的。我不认为它会抛出任何错误
