伙计们我要求列出上个月的所有日期,如下所示
20101201 20101202 20101203 20101204 20101205 .. .. .. .. .. .. .. .. 20101231@H_403_2@select TO_CHAR(TRUNC(SYSDATE,'MM')-1,'YYYYMMDD')-(level-1) as EACH_DATE from dual A connect by level < (TO_NUMBER(TO_CHAR(TRUNC(SYSDATE,'DD'))+1)@H_403_2@另请告诉我这个查询的问题,它说“缺少右括号”
SELECT /*+ PARALLEL (A,8) */ /*+ DRIVING_STATE */ TO_CHAR(TRUNC(TRUNC(SYSDATE,'MM'),'MONYYYY') "MONTH",TYPE AS "TRAFF",COLUMN,A_COUN AS "A_COUNT",COST FROM DATA_P B WHERE EXISTS ( select TO_NUMBER(TO_CHAR(TRUNC(SYSDATE,'YYYYMMDD')-(level-1)) EACH_DATE from dual A connect by level < TO_NUMBER(TO_CHAR(TRUNC(SYSDATE,'DD')+1) WHERE A.EACH_DATE = B.DATE order by EACH_DATE ASC )@H_403_2@强调文字
听起来你想要这样的东西
