Si está de acuerdo con lista concatenada , luego usa LISTAGG que se introdujo en Oracle 11g Release 2 .
SELECT weekday, LISTAGG(Sched_hrs, ',') WITHIN GROUP (ORDER BY weekday) AS Sched_hrs
FROM table
WHERE emplid = '12345' AND weekday_name= 1
GROUP BY weekday;
Por ejemplo,
SQL> column employees format a50
SQL> SELECT deptno, LISTAGG(ename, ',') WITHIN GROUP (ORDER BY ename) AS employees
2 FROM emp
3 GROUP BY deptno;
DEPTNO EMPLOYEES
