MySQL查询LEFT JOIN缺失值

Question

我的查询由于某种原因遗漏了大多数值的ISRC代码。包含ISRC CODE的两个记录是由于连接而出现的记录。这些查询的$artist_name = "Brady Hartvigsen"

$result = mysqli_query($con,"SELECT * 
        FROM isrc_codes i
        LEFT JOIN contributors c on i.ISRC_CODE = c.ISRC_CODE
        WHERE i.TRACK_ARTIST = '" . $artist_name . "' 
        OR c.CONTRIBUTOR = '" . $artist_name . "' 
        ORDER BY i.ISRC_CODE DESC");

这给了我这个输出

ISRC代码/歌曲/艺术​​家/贡献者/百分比

使用此代码，我可以使用ISRC CODEs输出，但不会在该人是其贡献者的轨道上输出

$result = mysqli_query($con,"SELECT * 
        FROM isrc_codes 
        WHERE TRACK_ARTIST = '" . $artist_name . "' 
        OR CONTRIBUTOR = '" . $artist_name . "' 
        ORDER BY ISRC_CODE DESC");

ISRC代码表

贡献者表

出于某种原因，它将ISRC代码放在[0]中但不放在[ISRC_CODE]

中
