详解 Mysql查询结果顺序按 in() 中ID 的顺序排列

实例代码：

?

1 2 3 4 5 6 7 8 9 10

< select id= "queryGBStyleByIDs" resultMap= "styleMap" >      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      <foreach collection= "styleNumIDs" item= "styleNumId" separator= "," open = "(" close = ")" >       #{styleNumId}      </foreach>      ORDER BY FIELD      <foreach collection= "styleNumIDs" item= "styleNumId" separator= "," open = "(style_num_id," close = ")" >        #{styleNumId}      </foreach>    </ select >

最终输出sql如下:

?

1 2	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);
