详解 mysql/' target='_blank'>mysql查询结果顺序按 in() 中ID 的顺序排列

实例代码：

<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:

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);
