Question

我需要从表REPORT_VIEW_PAGE中获取标题，计数和百分比。这很好。

SELECT DISTINCT TITLE, COUNT(TITLE) AS tot, ROUND(COUNT(TITLE)/(
SELECT COUNT(*) FROM REPORT_VIEW_PAGE), 4) AS per
FROM REPORT_VIEW_PAGE 
WHERE DAYCOUNT > '0'
GROUP BY TITLE
ORDER BY TITLE ASC

但是，如果尝试检索ID和TYPE，如

SELECT DISTINCT TITLE, ID, TYPE, COUNT(TITLE) AS tot, ROUND(COUNT(TITLE)/(
SELECT COUNT(*) FROM REPORT_VIEW_PAGE), 4) AS per
FROM REPORT_VIEW_PAGE 
WHERE DAYCOUNT > '0'
GROUP BY TITLE
ORDER BY TITLE ASC

我收到错误：

  

ORA-00979：不是GROUP BY表达式   00979. 00000 - ＆＃34;不是GROUP BY表达式＆＃34;   *原因：
  *动作：行错误：12列：24

任何人都可以提供帮助。

Answer 1

您需要按其他列进行分组

SELECT TITLE, ID, TYPE, COUNT(TITLE) AS tot, ROUND(COUNT(TITLE)/(
SELECT COUNT(*) FROM REPORT_VIEW_PAGE), 4) AS per
FROM REPORT_VIEW_PAGE 
WHERE DAYCOUNT > '0'
GROUP BY TITLE, Id, TYPE
ORDER BY TITLE ASC
