sqlserver中关于排序取数据的问题 ?12345SELECT * FROM (SELECT *,row_number() OVER (PARTITION BY wok.flag_3 ORDER BY wok.createtime desc) rownum FROM (select workh.corp_code,workh.corp_name,workh.begin_date, workh.createtime, workh.flag_1,workh.flag_2,workb.main_id,workb.production_quantity,workb.spare_capacity, workb.equipment_code,workb.flag_3 from imp_workorderh workh right join imp_workorderb workb on workb.main_id = workh.id where workh.teachingplanid = '0000AA10000000016F6U') wok ) h WHERE h.rownum = 1）此查询是按时间倒序排列后然后取出rownum为1 的数据，具体情况可以根据实际需求修改
