Question

不确定为什么它一直说缺少右括号，它强调了（*）处的错误。请帮忙，谢谢。

   SELECT FIRST, LAST 
    FROM OFFICERS
    WHERE OFFICER_ID IN (SELECT OFFICER_ID FROM CRIME_OFFICERS COUNT(*) as TotalReportsOfficer                  
    GROUP BY OFFICER_ID

    HAVING TotalReportsOfficer > ((SELECT COUNT(CRIME_ID) from CRIME_OFFICERS))/ (SELECT COUNT(OFFICER_ID) from OFFICERS));

错误：ORA-00907：缺少右括号   00907. 00000 - “缺少右括号”   *原因：
  *动作：行错误：3列：66

更新：我想找出每位官员所拥有的报告数量，然后比较每一位官员，以找出哪些人员的数量大于平均报告数量。

Answer 1

嗨，您可以使用以下查询

SELECT OF.FIRST, OF.LAST  FROM OFFICERS OF
    INNER JOIN (SELECT OFFICER_ID, COUNT(*) AS TotalReportsOfficer FROM OFFICERS
    GROUP BY CRIME_OFFICERS) COF
    ON (OF1.OFFICER_ID =COF.OFFICER_ID )
    HAVING COF.TotalReportsOfficer > ((SELECT COUNT(CRIME_ID) from CRIME_OFFICERS)/(SELECT COUNT(OFFICER_ID) from OFFICERS))

Answer 2

因为你在FROM之后有COUNT（*）;这不是Oracle SQL语法（或者，实际上是任何SQL语法）。

如果你想分享这个查询的目的（你用简单的英语想要做什么），也许我们可以帮助你找到一个有效的解决方案。你想在那里做什么？

SQL Oracle在计数中缺少右括号？
