详解 Mysql查询结果顺序按 in() 中ID 的顺序排列

实例代码：

 
    select style_num_id ,style_id,style_title,style_pic FROM gb_style where online = 1 AND is_hide = 0 and style_num_id in 
     
     #{styleNumId} 
     
    ORDER BY FIELD 
     
      #{styleNumId} 
     
   

最终输出sql如下:

select style_num_id ,style_id,style_title,style_pic FROM gb_style where online = 1 AND is_hide = 0 and style_num_id in (1,3,2,5) 
order by field (style_num_id,1,3,2,5);
