如何基于两个不同的列进行ORDER BY

Question

我有一个5列的表.当我列出表格时,我想按一列排序,以便将类型组合在一起,然后按字母顺序排列,以便于查找.

是否可以ORDER通过两个不同的列？

这是我目前的选择:

$query_rs_cms = "SELECT * FROM games ORDER BY type ASC";

我想我正在寻找的是:

SELECT * 
   FROM games 
ORDER BY type THEN ORDER BY title ASC";

Answer 1

您可以通过列名称或返回的列号指定ORDER BY.

所以你可以这样做:

SELECT * FROM games ORDER BY Type, Title

或类似的东西:

SELECT Type, Title, Column1, Column2 FROM games ORDER BY 1, 2

你也可以做升序和降序.因此,如果您想要类型降序但标题升序:

SELECT * FROM games ORDER BY Type DESC, Title ASC

Answer 2

SELECT * FROM games ORDER BY type, title

Answer 3

ORDER BY type, title

你可以做点什么

ORDER BY type DESC, title ASC

如果你需要的话.
