union

(SELECT e.ENAME 'NAME', SUM(l.HOURS) 'HOURS APPROVED' FROM labors l, emps e

WHERE l.EmpsID = e.EmpsID AND APPROVED = 'A' AND l.EmpsID = 'AGIUCL01'

AND l.DATE_WORK BETWEEN '2016-10-30' AND '2016-11-05')

AND l.EmpsID = 'AGIUCL01'

AND l.DATE_WORK BETWEEN '2016-10-30' AND '2016-11-05'

Query:

`SELECT e.ENAME 'NAME',`

SUM(CASE WHEN l.APPROVED='N' THEN l.HOURS ELSE 0 END) 'HOURS ENTERED',

SUM(CASE WHEN l.APPROVED='A' THEN l.HOURS ELSE 0 END) 'HOURS APPROVED',

SUM(CASE WHEN l.APPROVED='R' THEN l.HOURS ELSE 0 END) 'HOURS REJECTED'

FROM labors l ,emps e

where l.DATE_WORK BETWEEN '2016-10-30' AND '2016-11-05' and

e.TERM_DATE < e.REHIRE_DATE

or e.TERM_DATE IS NULL

group by (e.empsid)

You can use conditionals in the `SUM`

:

```
SELECT e.ENAME 'NAME',
SUM(CASE WHEN APPROVED='N' THEN l.HOURS ELSE 0 END) 'HOURS ENTERED',
SUM(CASE WHEN APPROVED='A' THEN l.HOURS ELSE 0 END) 'HOURS APPROVED',
SUM(CASE WHEN APPROVED='R' THEN l.HOURS ELSE 0 END) 'HOURS REJECTED'
FROM labors l, emps e
WHERE l.EmpsID = e.EmpsID
AND l.EmpsID = 'AGIUCL01'
AND l.DATE_WORK BETWEEN '2016-10-30' AND '2016-11-05'
```
