查看执行计划，发现ID=3处为 SORT UNIQUE ，而SQL语句并没有DISTINCT关键字，难道SQL进行自动改写了？
为了确认自己想法，我进行以下手动改写，把半连接手动改写成内连接：
改写之前，先确认表与表之间的关系：
select count(*),count(distinct DAILYAUDITNO) from MM_DAILYREPORT_DETAIL_TD;
COUNT(*) COUNT(DISTINCTDAILYAUDITNO)
-------- -----------------------
5111081 441898
select count(*),count(distinct DAILYAUDITNO) from MM_DAILYREPORT_TD;
COUNT(*) COUNT(DISTINCTDAILYAUDITNO)
-------- -----------------------
441940 441940
--表MM_DAILYREPORT_TD与表MM_DAILYREPORT_DETAIL_TD是1:N的关系，所以改写时候，需要先去重，再连接。
SELECT D.DAILYAUDITNO, D.TRANSTOACC
FROM PB_DOIC.MM_DAILYREPORT_TD D
INNER JOIN (SELECT DISTINCT DAILYAUDITNO
FROM PB_DOIC.MM_DAILYREPORT_DETAIL_TD
WHERE BUSINESSONE || BUSINESSTWO NOT IN
('604988', '605988', '606988', '607988')
AND BUSINESSTWO != '991') TD
ON D.DAILYAUDITNO = TD.DAILYAUDITNO
WHERE D.REPORTSTATUS = '4'
AND D.TRANSTOACC IN ('00', 'B1')
AND NOT EXISTS
(SELECT 1

WHERE E.DAILYAUDITNO = D.DAILYAUDITNO
AND E.BUSINESSONE || E.BUSINESSTWO NOT IN

AND E.BUSINESSTWO != '991'
