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 我做的最后一件事是添加

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

在整个查询之后。我已经被困在这两天了......有人可以帮忙吗？

它的这个子选择：

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 aUNION ALL中，您需要两个选择的选择列表中的项目数量相同。您在第一个中添加了 MONTH，因此您需要在第二个中添加一些内容：

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

关于谢回答和您对此回答的评论——您可以像下面这样编辑查询

在将 char 更改为日期时，您还给出了错误的日期格式（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
