在ORA-01789中卡住:查询块的结果列数不正确

Question

我看不出问题出在哪里。它一直显示ORA-01789:查询块的结果列数不正确我最后做的一件事是添加

substrb(TO_CHAR (TO_DATE ('20130601','YYYY-MM-DD')+LEVEL- 1, 'YYYYMMDD'), -4, 2) ||'월'AS MONTH

在整个查询之后。我已经困在这里两天了.有人能帮上忙吗？

Answer 1

它是这个子选择：

SELECT 
    TO_CHAR (TO_DATE ('20130601','YYYY-MM-DD')+LEVEL- 1, 'YYYY.MM.DD') AS DAY,
    ceil( ... ) || ' WEEK' AS WEEK,
    substrb( ... ) ||'MONTH'AS MONTH
from DUAL
CONNECT BY TO_DATE('20130601', 'YYYY-MM-DD') + LEVEL - 1  <=  TO_DATE('20130830', 'YYYY-MM-DD')
UNION ALL
SELECT 'SUM', '' FROM DUAL

在UNION ALL中，两个选择在选择列表中需要相同数量的项。您向第一个月添加了月份，因此需要向第二个月添加一些内容：

SELECT 
    TO_CHAR (TO_DATE ('20130601','YYYY-MM-DD')+LEVEL- 1, 'YYYY.MM.DD') AS DAY,
    ceil( ... ) || ' WEEK' AS WEEK,
    substrb( ... ) ||'MONTH'AS MONTH
from DUAL
CONNECT BY TO_DATE('20130601', 'YYYY-MM-DD') + LEVEL - 1  <=  TO_DATE('20130830', 'YYYY-MM-DD')
UNION ALL
SELECT 
    'SUM', /*DAY*/ 
    '',    /*WEEK*/
    ''     /*MONTH*/ 
FROM DUAL

Answer 2

关于谢的回答和你对这个答案的评论--你可以像下面这样编辑查询

将字符更改为日期时，您给出的另一个错误日期格式(在'to_date‘函数中)

SELECT 
    TO_CHAR (TO_DATE ('20130601','YYYYMMDD')+LEVEL- 1, 'YYYY.MM.DD') AS DAY,
    ceil( ... ) || ' WEEK' AS WEEK,
    substrb( ... ) ||'MONTH'AS MONTH
from DUAL
CONNECT BY TO_DATE('20130601', 'YYYYMMDD') + LEVEL - 1  <=  TO_DATE('20130830', 'YYYYMMDD')
UNION ALL
SELECT 'SUM', '' as week,'' as month FROM DUAL
