<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>
最終輸出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);
