Mysql自定义排序依据和字母排序依据: [英] Mysql custom order by and alphabetical order by:

问题描述

我正在使用以下查询:

$query = "SELECT * FROM `$table[$a]` ORDER BY FIELD(typeof,'pdf','swf','img','web')";

选择并自定义我的mysql查询，它工作得很好，除了每个typeof中有多个文件，我现在想按字母顺序对它们进行排序，但仍保留其typeof顺序.有道理吗?

to select and customly order my mysql query, it works great except there are multiple files within each typeof and I now want to order them alphabetically yet retaining their typeof order. Make sense?

推荐答案

SELECT * FROM `$table[$a]` 
ORDER BY 
  FIELD(typeof,'pdf','swf','img','web'), --first order by type
  filename  --then by filename
