公司使用的是postgresql数据库
今天在写项目的时候，遇到了这样一个问题，自己写出的sql语句，如果一次性全部查询出来一共有24条数据，这24条数据也是按照bussinessdate进行降序排列的，显示的最近日期就是自己今天操作的，2020-06-11
但是如果自己加上分页，控制每页显示10条的化，就虽然查询出来的结果也是按照降序排列的，但是6-11号的数据就没有显示，很是奇怪，最后询问同事，解决了问题：
原先的代码：
<select id="queryScoreDetailList" parameterType="com.picc.hmbms.outinterface.scoreDetail.vo.ScoreDetailInfoQueryVo" resultMap="reMemberScoreInfo_i"> select * from (select tmp_page.* from ( select distinct tsg.member_code memberCode, row_number() OVER() as rownum, tsg.SCORE_TYPE , <!-- tsd.CONSUMEORG businessOrg, --> <!-- tsd.GRANTORG grantOrg, --> tsd.GRENT_PROJECT, to_char(tsd.insert_time,‘yyyy-MM-dd‘) insertTime, to_char(tsg.end_date,‘yyyy-MM-dd‘) endDate, tss.order_no orderNo, tsg.content, (case when tsd.consumeorg is null then tsd.grantorg else tsd.consumeorg end ) businessOrg, tsd.SYS_NO sysNo , (case when tsd.SCORE is null then 0 else round(tsd.SCORE,0) end) score, (case when tss.consumer_date is null then to_char(tsg.GRANT_DATE,‘yyyy-MM-dd hh24:mi:ss‘) else to_char(tss.consumer_date,‘yyyy-MM-dd hh24:mi:ss‘) end) businessDate, tsd.BUSINESS_TYPE businessType from t_member_score_detail tsd left join t_score_grent tsg on tsg.Member_Code = tsd.member_code and tsg.SCORE_GRENT_ID = tsd.SCORE_GRENT_ID left join t_score_settel tss on tss.Member_Code = tsd.member_code and tss.SCORE_SETTEL_ID = tsd.SCORE_SETTEL_ID <if test="memberCode != null and ‘‘ != memberCode"> where tsd.MEMBER_CODE = #{memberCode, jdbcType=VARCHAR} </if> <if test="startDate != null and ‘‘!= startDate"> AND ( to_date(to_char(tsd.GRANT_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘) <![CDATA[ >= ]]>to_date(#{startDate},‘yyyy-MM-dd‘) or to_date(to_char(tsd.CONSUME_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘)<![CDATA[ >= ]]> to_date(#{startDate},‘yyyy-MM-dd‘)) </if> <if test="endDate != null and ‘‘ != endDate"> AND ( to_date(to_char(tsd.GRANT_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘) <![CDATA[ <= ]]> to_date(#{endDate},‘yyyy-MM-dd‘) or to_date(to_char(tsd.CONSUME_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘) <![CDATA[ <= ]]> to_date(#{endDate},‘yyyy-MM-dd‘)) </if> order by businessDate desc ) tmp_page where rownum <![CDATA[ <= ]]> #{maxNum} and tmp_page.businessDate is not null) lm where rownum > #{minNum} </select>
修改之后的代码：
<select id="queryScoreDetailList" parameterType="com.picc.hmbms.outinterface.scoreDetail.vo.ScoreDetailInfoQueryVo" resultMap="reMemberScoreInfo_i"> select * from (select tmp_page.* from ( select distinct tsg.member_code memberCode, row_number() OVER (order by consumer_date ) AS rownum, tsg.SCORE_TYPE , <!-- tsd.CONSUMEORG businessOrg, --> <!-- tsd.GRANTORG grantOrg, --> tsd.GRENT_PROJECT, to_char(tsd.insert_time,‘yyyy-MM-dd‘) insertTime, to_char(tsg.end_date,‘yyyy-MM-dd‘) endDate, tss.order_no orderNo, case when tsd.score_type=‘06‘ then ‘挑战赢积分活动扣100积分‘ else tsg.CONTENT end, (case when tsd.consumeorg is null then tsd.grantorg else tsd.consumeorg end ) businessOrg, tsd.SYS_NO sysNo , (case when tsd.SCORE is null then 0 else round(tsd.SCORE,0) end) score, (case when tss.consumer_date is null then to_char(tsg.GRANT_DATE,‘yyyy-MM-dd hh24:mi:ss‘) else to_char(tss.consumer_date,‘yyyy-MM-dd hh24:mi:ss‘) end) businessDate, tsd.BUSINESS_TYPE businessType from t_member_score_detail tsd left join t_score_grent tsg on tsg.Member_Code = tsd.member_code and tsg.SCORE_GRENT_ID = tsd.SCORE_GRENT_ID left join t_score_settel tss on tss.Member_Code = tsd.member_code and tss.SCORE_SETTEL_ID = tsd.SCORE_SETTEL_ID <if test="memberCode != null and ‘‘ != memberCode"> where tsd.MEMBER_CODE = #{memberCode, jdbcType=VARCHAR} </if> <if test="startDate != null and ‘‘!= startDate"> AND ( to_date(to_char(tsd.GRANT_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘) <![CDATA[ >= ]]>to_date(#{startDate},‘yyyy-MM-dd‘) or to_date(to_char(tsd.CONSUME_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘)<![CDATA[ >= ]]> to_date(#{startDate},‘yyyy-MM-dd‘)) </if> <if test="endDate != null and ‘‘ != endDate"> AND ( to_date(to_char(tsd.GRANT_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘) <![CDATA[ <= ]]> to_date(#{endDate},‘yyyy-MM-dd‘) or to_date(to_char(tsd.CONSUME_DATE, ‘yyyy-MM-dd‘), ‘yyyy-MM-dd‘) <![CDATA[ <= ]]> to_date(#{endDate},‘yyyy-MM-dd‘)) </if> order by businessDate desc ) tmp_page where rownum <![CDATA[ <= ]]> #{maxNum} and tmp_page.businessDate is not null) lm where rownum > #{minNum} </select>
总的来说：一定要在over之后添加上排序的条件。
