How to combine two queries to get one result? - sql

Question

I need two combine two queries to get one result only. Here's the first code.
SELECT FKLTI_KTRGN, COUNT(DISTINCT VIEW_PELAJAR_ENROLL.MB_NAMA) AS BIL_UG
FROM VIEW_PELAJAR_ENROLL, KOD_BANGSA, KOD_NEGERI, JANTINA, KOD_AGAMA, KOD_CACAT, TARAF_KAHWIN
WHERE KOD_KTRGN_PROGRAM = 'SARJANA MUDA'
AND MS_SESI = '2015/2016'
AND MB_BANGSA = KOD_BANGSA
AND KOD_NEGERI = MB_ASAL
AND MB_JANTINA = JAN_KOD
AND KOD_AGAMA = MB_AGAMA
AND KOD_CACAT = MB_CACAT
AND KOD_TARAF = MB_TARAF_KAHWIN
AND MS_STATUS_SEMASA IN
(SELECT SP_KOD
FROM STATUS_PELAJAR
WHERE STATUS_ENROLL = 'Y'
AND SP_TAMAT IS NULL
AND SP_KOD = MS_STATUS_SEMASA)
GROUP BY FKLTI_KTRGN
And this is the second code.
SELECT FKLTI_KTRGN, COUNT(DISTINCT PELAJAR_BIODATA.MBUT_NAMA) AS BIL_PG
FROM PELAJAR_BIODATA,KOD_NEGERI,FAKULTI,KOD_IJAZAH,PELAJAR_BUTIR_PENGAJIAN,STATUS_PENGAJIAN A,
KOD_STATUS_PELAJAR_IPS, KOD_CACAT, KOD_BANGSA, E_KOD_PENGAJIAN, JANTINA, KOD_PROGRAM
WHERE A.STAT_STATUS IN (SELECT KOD_STATUS
FROM KOD_STATUS_PELAJAR_IPS
WHERE STATUS_ENROLL='Y'
AND KOD_STATUS=STAT_STATUS)
AND A.STAT_NOMKPB=MBUT_NOMKPB
AND PBP_PROGRAM IN ('5','6')
AND MBUT_ASAL=KOD_NEGERI(+)
AND SUBSTR(A.STAT_KOD_IJAZAH,1,1)=FKLTI_KOD
AND PBP_PROGRAM=KOD_PROGRAM.KOD_PROGRAM
AND A.STAT_KOD_IJAZAH=KOD_IJAZAH_UM
AND A.STAT_NODAFTAR=PBP_NODAFTAR
AND MBUT_CACAT=KOD_CACAT
AND KOD_BANGSA=MBUT_BANGSA
AND PBP_JENIS_PENGAJIAN=KOD_JNS_PENGAJIAN
AND MBUT_JANTINA=JAN_KOD
AND MBUT_WARGA IS NOT NULL
AND MBUT_BANGSA IS NOT NULL
AND MBUT_JANTINA IS NOT NULL
AND MBUT_NEGERI IS NOT NULL
AND PBP_PROGRAM IS NOT NULL
AND A.STAT_STATUS=KOD_STATUS
AND PBP_KOD_IJAZAH IS NOT NULL
AND A.STAT_SESI||A.STAT_SEMESTER IN (SELECT MAX(B.STAT_SESI||B.STAT_SEMESTER) FROM STATUS_PENGAJIAN B
WHERE B.STAT_NODAFTAR=A.STAT_NODAFTAR
AND B.STAT_NOMKPB=A.STAT_NOMKPB
AND A.STAT_SESI||A.STAT_SEMESTER=B.STAT_SESI||B.STAT_SEMESTER)
AND A.STAT_SESI = '2015/2016'
group by FKLTI_KTRGN
This is the expected result:
This is what i get:
I've tried to use UNION but it doesn't work. Anyone can help me? I really need your help. Thank you in advance!

Answer 1

In order to use union, you need to have the same number of fields and the same field name of both query.
as in both queries of yours, the second field has different name: BIL_PG, BIL_UG

Answer 2

Try this
select * from
(SELECT FKLTI_KTRGN, COUNT(DISTINCT VIEW_PELAJAR_ENROLL.MB_NAMA) AS BIL_UG
FROM VIEW_PELAJAR_ENROLL, KOD_BANGSA, KOD_NEGERI, JANTINA, KOD_AGAMA, KOD_CACAT, TARAF_KAHWIN
WHERE KOD_KTRGN_PROGRAM = 'SARJANA MUDA'
AND MS_SESI = '2015/2016'
AND MB_BANGSA = KOD_BANGSA
AND KOD_NEGERI = MB_ASAL
AND MB_JANTINA = JAN_KOD
AND KOD_AGAMA = MB_AGAMA
AND KOD_CACAT = MB_CACAT
AND KOD_TARAF = MB_TARAF_KAHWIN
AND MS_STATUS_SEMASA IN
(SELECT SP_KOD
FROM STATUS_PELAJAR
WHERE STATUS_ENROLL = 'Y'
AND SP_TAMAT IS NULL
AND SP_KOD = MS_STATUS_SEMASA)
GROUP BY FKLTI_KTRGN)
union
select * from (SELECT FKLTI_KTRGN, COUNT(DISTINCT PELAJAR_BIODATA.MBUT_NAMA) AS BIL_PG
FROM PELAJAR_BIODATA,KOD_NEGERI,FAKULTI,KOD_IJAZAH,PELAJAR_BUTIR_PENGAJIAN,STATUS_PENGAJIAN A,
KOD_STATUS_PELAJAR_IPS, KOD_CACAT, KOD_BANGSA, E_KOD_PENGAJIAN, JANTINA, KOD_PROGRAM
WHERE A.STAT_STATUS IN (SELECT KOD_STATUS
FROM KOD_STATUS_PELAJAR_IPS
WHERE STATUS_ENROLL='Y'
AND KOD_STATUS=STAT_STATUS)
AND A.STAT_NOMKPB=MBUT_NOMKPB
AND PBP_PROGRAM IN ('5','6')
AND MBUT_ASAL=KOD_NEGERI(+)
AND SUBSTR(A.STAT_KOD_IJAZAH,1,1)=FKLTI_KOD
AND PBP_PROGRAM=KOD_PROGRAM.KOD_PROGRAM
AND A.STAT_KOD_IJAZAH=KOD_IJAZAH_UM
AND A.STAT_NODAFTAR=PBP_NODAFTAR
AND MBUT_CACAT=KOD_CACAT
AND KOD_BANGSA=MBUT_BANGSA
AND PBP_JENIS_PENGAJIAN=KOD_JNS_PENGAJIAN
AND MBUT_JANTINA=JAN_KOD
AND MBUT_WARGA IS NOT NULL
AND MBUT_BANGSA IS NOT NULL
AND MBUT_JANTINA IS NOT NULL
AND MBUT_NEGERI IS NOT NULL
AND PBP_PROGRAM IS NOT NULL

AND A.STAT_SESI||A.STAT_SEMESTER=B.STAT_SESI||B.STAT_SEMESTER)
AND A.STAT_SESI = '2015/2016'
group by FKLTI_KTRGN)
