Given the lack of details it is very difficult to offer much assistance here. I don't really understand why you have the subquery at all. I would also recommend that use the newer join styles instead of the old styles. It is much easier to read and less likely to produce accidental cartesian products. Additionally I would suggest to use meaningful aliases instead of just numbering them.
This query should produce the same thing as the first query you posted. It is however a lot shorter and a lot easier to read.
SELECT sc.SUBCASE_NUMBER, SUM(otl.DURATION/60) AS TOTAL_DURATION
FROM SUBCASE sc
JOIN ONSITE_TIME_LOG otl on sc.SUBCASE_OBJID = otl.SUBC_ONSITE2SUBCASE
WHERE
LEFT(sc.SUBCASE_NUMBER, 7) IN
(
'2049356',
'2049462',
'2057852',
'2057877',
'2057897',
'2057930',
'2057948',
'2057963',
'2057984',
'2057996',
'2058015',
'2058032',
'2058049',
'2066771'
)
OR sc.SUBCASE_TITLE LIKE '%CITS%Audit%'
GROUP BY sc.SUBCASE_NUMBER
ORDER BY sc.SUBCASE_NUMBER
Now I realize I haven't actually helped with your issue. Are you doing this in Oracle or SQL?
