如何使用group by和order by

Question

如何将照片库分组并按字母顺序按升序排序？ 我的代码：

$getid = $_SESSION['idSession'];

$sql = mysqli_query($mysqli, "
SELECT name_gallery
     , folder
     , img
     , id_client 
  FROM alboom 
 WHERE id_adm = '$getid' 
 GROUP 
    BY id_client 
 ORDER 
    BY name_gallery ASC
");

我的表格结构 table struct

我的输出= test gallery01, test gallery02, test gallery03, test gallery04, test gallery05;

我应该如何处理我的代码以按字母顺序对图像进行排序？

Answer 1

我对mysql知之甚少，但它几乎与Oracle相似

SELECT name_gallery      ，文件夹      ，img      ，id_client   从alboom  WHERE id_adm ='$ getid'  组     按名称_gallery      ，文件夹      ，img      ，id_client  订购     按名称_gallery “）;

ASC不需要按升序排序。
