Sql 查询以查找在其工作角色方面休了超过其合格假期的员工

我有以下列的表格：

Employee24( EMPLOYEEID, FIRSTNAME, LASTNAME, GENDER, JOBROLES);

Leave25( EMPLOYEEID,LEAVEID, LEAVETYPE, STARTDATE, ENDDATE);

JOBROLESELIGIBLELE(JOBROLES, ELIGIBLE_SICK_LEAVES, ELIGIBLE_EARNED_LEAVES)

我想写一个查询，查找在工作角色方面休了超过法定假期的员工

SELECT * 
  FROM EMPLOYEE24 
  WHERE EMPLOYEEID IN (SELECT EMPLOYEEID 
                        FROM LEAVE25 L WHERE (STARTDATE-ENDDATE)
    < (SELECT ELIGIBLE_SICK_LEAVES + ELIGIBLE_EARNED_LEAVES 
              FROM  JOBROLESELIGIBELE 
              GROUP BY JOBROLES));

这将查找超过每种休假类型的休假金额的每个用户：

请把帽子锁上！示例数据、期望的结果和术语的定义都会有所帮助。表的主键是什么？是Employee24EmployeeId、Leave25EmployeeId、LeaveId`和JobRolesEligibeleJobRoles吗？@Thorsten Kethner是的。数据模型似乎有点不对劲。我假设LEAVETYPE表示符合条件的病假、符合条件的挣得的假，并且接受的答案支持这一假设。情况不应该如此。在所有表中为不同的休假类型使用列，或为不同的休假类型使用行。不要把两者混为一谈。
