Hello all,
I am working with a query that does some counts. I've hit a brick wall and can't get passed trying to figure out how I can make the query show percentages %.
Here is the query:
select "COUNTRY",
count ("MSS") "COUNT_MSS"
FROM (
SELECT DISTINCT
ms.journal_id||ms.yr_of_issue||ms.ms_sequence_no||ms.check_char MSS,
m.RVIEWNUM_INIT_INITSET||M.RVIEWNUM_INIT_SITE||M.RVIEWNUM_INITSEQ "NAME_ID",
NVL(a.country,'USA') "COUNTRY"
FROM mscript ms, reviewms m, address a, journal j
WHERE (m.first_return between '01/01/2003' and '12/31/2003'
or m.second_return between '01/01/2003 and '12/31/2003'
or m.second_return between '01/01/2003 and '12/31/2003')
and ms.journal_id = j.journal_id
and M.MSNUMBER_JCO! DE = ms.journal_id
and M.MSNUMBER_YRISSUE = ms.yr_of_issue
and M.MSNUMBER_MS_SEQNO = ms.ms_sequence_no
and M.MSNUMBER_CKCHAR = ms.check_char
and m.RVIEWNUM_INIT_INITSET = a.namekey_init_initset(+)
and M.RVIEWNUM_INIT_SITE = a.namekey_init_site(+)
and M.RVIEWNUM_INITSEQ = a.namekey_initseq(+)
and a.addtype_addrstyp in ('m', 'p')
and a.addtype_typeno = 1
and (a.addr_end_date is null
or a.addr_end_date > sysdate)
and (first_recommend not in ('1','2','3','4','5','6','7','8','9','F','P','N','S','u')
or second_recommend not in ('1','2','3','4','5','6','7','8','9','F','P','N','S','u'))
order by 1)
GROUP BY ROLLUP(COUNTRY)
And the output:
COUNTRY COUNT_MSS
AUSTRALIA 1
AUSTRIA 2
BELGIUM 4
CANADA 20
CHILE 1
CHINA 3
CZECH REPUBLIC 1
DENMARK 4
ENGLAND 10
46
Is there a way I can also display a percentage column, that is the percentage of the total in the same SQL statement?
As always thanks so much!
Viktor
Will this work? (ran a simple test case that worked, although this may not):
select country,count_mss,round((count_mss/decode(overall_total,0,1,overall_total))*100)||'%' pct
from (
select "COUNTRY",
count ("MSS") over (partition by "MSS") "COUNT_MSS",
count("MSS") over () overall_total
FROM (
SELECT DISTINCT
ms.journal_id||ms.yr_of_issue||ms.ms_sequence_no||ms.check_char MSS,
m.RVIEWNUM_INIT_INITSET||M.RVIEWNUM_INIT_SITE||M.RVIEWNUM_INITSEQ "NAME_ID",
NVL(a.country,'USA') "COUNTRY"
FROM mscript ms, reviewms m, address a, journal j
WHERE (m.first_return between '01/01/2003' and '12/31/2003'
or m.second_return between '01/01/2003 and '12/31/2003'
or m.second_return between '01/01/2003 and '12/31/2003')
and ms.journal_id = j.journal_id
and M.MSNUMBER_JCO! DE = ms.journal_id
and M.MSNUMBER_YRISSUE = ms.yr_of_issue
and M.MSNUMBER_MS_SEQNO = ms.ms_sequence_no
and M.MSNUMBER_CKCHAR = ms.check_char
and m.RVIEWNUM_INIT_INITSET = a.namekey_init_initset(+)
and M.RVIEWNUM_INIT_SITE = a.namekey_init_site(+)
and M.RVIEWNUM_INITSEQ = a.namekey_initseq(+)
and a.addtype_addrstyp in ('m', 'p')
and a.addtype_typeno = 1
and (a.addr_end_date is null
or a.addr_end_date > sysdate)
and (first_recommend not in ('1','2','3','4','5','6','7','8','9','F','P','N','S','u')
or second_recommend not in ('1','2','3','4','5','6','7','8','9','F','P','N','S','u'))
order by 1)
GROUP BY ROLLUP(COUNTRY))
(not sure how it will react to a 'group by rollup..' though.
