Answer 1

select emp_type, emp_status, course_attended, 1 as order1, 1 as order2
from employee e
union all
select emp_type, emp_status, sum(course_attended), 1 as order1, 0 as order2
from employee e
group by emp_type, emp_status
union all
select emp_type, '' as emp_status, sum(course_attended), 0 as order1, 0 as order2
from employee e
group by emp_type

order by emp_type, emp_status, order1, order2

Answer 2

您提出的任何输出格式在SQL中都有点困难。你可以试试下面的内容，然后根据你在PLSQL中的要求重新构建结果。

SELECT EMP_TYPE ||'--'||EMP_STATUS||'--'||EMP_NAME,SUM(COURSE_ATTENDED) FROM
(SELECT 1 EMP_ID ,'AAA' EMP_NAME,'On Roll' EMP_TYPE, 'A' EMP_STATUS, 2 COURSE_ATTENDED FROM dual
UNION ALL
SELECT 2 ,'BBB', 'Contractor' , 'A' , 4 FROM dual
UNION ALL
SELECT 3 , 'CCC' , 'On Roll', 'I' , 1 FROM dual
UNION ALL
SELECT 4 , 'CDS' , 'Contractor' , 'I' , 7 FROM dual
UNION ALL
SELECT 5 , 'Ada' , 'On Roll' , 'A' , 2 FROM dual
UNION ALL
SELECT 6 , 'BfB' , 'Contractor' , 'A' , 2 FROM dual)
GROUP BY GROUPING SETS ((EMP_TYPE),(EMP_TYPE,EMP_STATUS),(EMP_TYPE,EMP_STATUS,EMP_NAME));
