Integrating the two parts of a union select statement...

Question

Hi everybody ,
I have a query such as the one follows...:
SELECT TMHMA , DATES , COUNT(EXETASI)
FROM PARAGG_LAB_TESTS_LOCAL_MS PAR_TESTS_MS , PARAGG_LAB_TESTS_LOCAL PAR_TESTS_DET
WHERE PAR_TESTS_MS.BARCODE=PAR_TESTS_DET.BARCODE
GROUP BY TMHMA , DATES
UNION
SELECT TMHMA , DATES , SUM(NUM_TESTS)
FROM NUM_TESTS_PROFILE ,
PARAGG_LAB_PROFILES_LOCAL_MS PAR_PROFILE_MS , PARAGG_LAB_PROFILES_LOCAL PAR_PROFILE_DET
WHERE PAR_PROFILE_MS.BARCODE=PAR_PROFILE_DET.BARCODE AND
PAR_PROFILE_DET.PROFILE=NUM_TESTS_PROFILE.CODE_PROFILE
GROUP BY TMHMA , DATES
Is this possible to integrate the two parts of the above union sql statement into one (without using union) and compute the result of COUNT(EXETASI)+SUM(NUM_TESTS)..????
Thanks , a lot
Simon

Hi , Jameel
it is not correct because the columns more than one table has the columns TMHMA and DATES . To indicate this , i rewrite the query...
SELECT PAR_TESTS_MS.TMHMA , PAR_TESTS_MS.DATES , COUNT(EXETASI)
FROM PARAGG_LAB_TESTS_LOCAL_MS PAR_TESTS_MS , PARAGG_LAB_TESTS_LOCAL PAR_TESTS_DET
WHERE PAR_TESTS_MS.BARCODE=PAR_TESTS_DET.BARCODE
GROUP BY TMHMA , DATES
UNION
SELECT PAR_PROFILE_MS.TMHMA , PAR_PROFILE_MS.DATES , SUM(NUM_TESTS)
FROM NUM_TESTS_PROFILE ,
PARAGG_LAB_PROFILES_LOCAL_MS PAR_PROFILE_MS , PARAGG_LAB_PROFILES_LOCAL PAR_PROFILE_DET
WHERE PAR_PROFILE_MS.BARCODE=PAR_PROFILE_DET.BARCODE AND
PAR_PROFILE_DET.PROFILE=NUM_TESTS_PROFILE.CODE_PROFILE
GROUP BY TMHMA , DATES
and the results
TMHMA DATES COUNT(EXETASI)
11 19/8/2005 1
11 15/9/2005 4
11 15/9/2005 57
11 16/9/2005 58
11 10/10/2005 4
11 10/10/2005 72
11 14/10/2005 3
11 14/10/2005 160
11 7/4/2006 2
11 7/4/2006 53
11 8/4/2006 2
11 8/4/2006 61
11 9/4/2006 2
11 9/4/2006 31
209 30/4/2006 3
209 30/4/2006 31
209 8/5/2006 4
209 8/5/2006 31
88 20/10/2005 2
88 20/10/2005 59
and the expected results.....
TMHMA DATES COUNT(EXETASI)
11 19/8/2005 1
11 15/9/2005 61
11 16/9/2005 58
11 10/10/2005 76
11 14/10/2005 163
11 7/4/2006 55
11 8/4/2006 63b]
11 9/4/2006 [b]33
209 30/4/2006 34
209 8/5/2006 35
88 20/10/2005 61
