---原始数据

-- 以下结果是运行：（将连续的数据通过RN展示表示是一组数据）

 SELECT OCCUR_DATE,SITE_NO,VOUH_NO,ACCOUNT, TRUNC(T.OCCUR_DATE-ROW_NUMBER() OVER(PARTITION BY T.ACCOUNT ORDER BY T.OCCUR_DATE)) RN
       FROM  TEMP_225 T

 /*求出连续三天都符合条件的数据，如果有一天不连续，即不取出*/

最终语句

 SELECT ACCOUNT,OCCUR_DATE,START_DATE,SITE_NO,END_DATE,AMOUNT,TX_NUM FROM(
   SELECT ACCOUNT,sysdate OCCUR_DATE,MIN(OCCUR_DATE) START_DATE ,MIN(SITE_NO)SITE_NO ,MAX(OCCUR_DATE) END_DATE,TO_NUMBER(SUM(VOUH_NO)) AMOUNT,COUNT(1)TX_NUM FROM (
     
      SELECT OCCUR_DATE,SITE_NO,VOUH_NO,ACCOUNT, TRUNC(T.OCCUR_DATE-ROW_NUMBER() OVER(PARTITION BY T.ACCOUNT ORDER BY T.OCCUR_DATE)) RN
       FROM TEMP_225 T
      )GROUP BY ACCOUNT,RN
  HAVING COUNT(1)>=3
