Get next row if coloumn has same value - sql

Question

Good day, I'm trying to select a data. Please check my query and table first.
I have this query
select * from
(
SELECT * from
(
select distinct TOP 201233 row, b.OutletCode as 'Kode Otlet',
i.Description as 'Area',
c.Nilai,a.Nip, b.Fullname 'Nama Lengkap', f.positioncode as 'Posisi Sebelumnya',
case when a.[status]=0
then j.ApprovedDate else p.ApprovedDate
end as 'Tanggal Upgrade/Demosi Sebelumnya',
d.positioncode as 'Posisi Baru', a.tanggal as 'Tanggal Upgrade/Demosi'
from penilaian_header a
left join Employee b on a.Nip = b.Nip
left join Position f on b.PositionCode = f.PositionCode
left join Position d on a.PositionCode = d.PositionCode
left join arealeader g on g.OutletCode = b.OutletCode
left join outlet h on g.OutletCode = h.OutletCode
left join area i on i.areacode = h.areacode
left join cutoff k on a.periode = k.cutoffcode
left join
(select ROW_NUMBER() OVER(PARTITION BY KodePenilaianH ORDER BY idPenilaiand ASC) AS Row,
Nilai,KodePenilaianH from penilaian_Detail ) c on a.KodePenilaian = c.KodePenilaianH
left join
( SELECT ROW_NUMBER() OVER (PARTITION BY nip ORDER BY ApprovedDate desc) AS rownumber,
ApprovedDate, Nip FROM historyposition ) AS p on a.nip=p.nip and p.rownumber = 2
left join ( SELECT ROW_NUMBER() OVER (PARTITION BY nip ORDER BY ApprovedDate desc) AS rownumber, ApprovedDate, Nip
FROM historyposition ) AS j on a.nip=j.nip and j.rownumber = 1
where a.flag = 1 and h.AreaCode like '%%'
and Periode like '%CO-2016-9-16-15%' and a.nip = '1004863'
--and tanggal <= k.[to] and tanggal >= k.[from]
order by i.Description asc) nilai pivot ( sum(nilai) for row in ([1],[2],[3],[4],[5]) ) piv)A order by Area;
with above query i get this result
and i have this table HistoryPosition
KodeMutasiP OldPosition NewPosition ApprovedBy ApprovedDate Nip KodePenilaian
HP0000514 P007 P007 0802678 2016-09-15 1004863 PE0000787
HP0000513 P007 P007 0802678 2016-04-04 1004863 PE0000130
NULL NULL P007 NULL 2016-04-04 1004863 NULL
NULL NULL P041 NULL 2016-01-20 1004863 NULL
NULL NULL P007 NULL 2015-02-12 1004863 NULL
ok. So what i want to do is set Posisi Sebelumnya and Tanggal Upgrade/Demosi Sebelumnya in the first picture with newposition and Approveddate from the second picture.
But with this condition
if newposition and nip col in the second picture same with the second row then jump to the second, if the second same with the third then jump to the fourth, if the fourth different with the third then choose the third.
I have write the query to choose it here is my query
select * INTO #tMP from historyposition where nip = '1004863' order by approveddate desc
declare #NewPosition varchar(50), #NewPositionLast varchar(50), #ApproveDate datetime, #ApproveDateLast datetime
select top 1 #NewPositionLast = NewPosition, #ApproveDateLast=ApprovedDate from #tmp
WHILE EXISTS (SELECT * FROM #tMP)
BEGIN
select top 1 #NewPosition = NewPosition, #ApproveDate=ApprovedDate from #tmp
if (#NewPosition = #NewPositionLast)
begin
set #NewPositionLast = #NewPosition
set #ApproveDateLast = #ApproveDate
end
else
begin
break
end
delete top(1) #tMP
END
select #NewPositionLast , #ApproveDateLast
drop table #tMP
and i get this result
| P007 | 2016-04-04 00:00:00.000 |
the result is like what i expected.
so my question how to set the Posisi Sebelumnya and Tanggal Upgrade/Demosi Sebelumnya with the result of my last query.
Sorry for my bad english.
here it's my expected result .
I know it's same with the the first picture. But its not right. that because in my first query i choose the second row.
select * from
(
SELECT * from
(
select distinct TOP 201233 row, b.OutletCode as 'Kode Otlet', i.Description as 'Area',
c.Nilai,a.Nip, b.Fullname 'Nama Lengkap',
case when
l.ShortDesc IS NULL then f.ShortDesc else l.ShortDesc
end
as 'PosisiSebelumnya',
-----
z.approveddate,
------
d.ShortDesc as 'Posisi Baru', a.tanggal as 'Tanggal Upgrade/Demosi'
from penilaian_header a
left join Employee b on a.Nip = b.Nip
left join Position f on b.PositionCode = f.PositionCode
left join Position d on a.PositionCode = d.PositionCode
left join position l on a.posisisaatini = l.positioncode
left join arealeader g on g.OutletCode = b.OutletCode
left join outlet h on g.OutletCode = h.OutletCode
left join area i on i.areacode = h.areacode
left join cutoff k on a.periode = k.cutoffcode
left join
(select ROW_NUMBER() OVER(PARTITION BY KodePenilaianH ORDER BY idPenilaiand ASC) AS Row,
Nilai,KodePenilaianH from penilaian_Detail ) c on a.KodePenilaian = c.KodePenilaianH
left join (
select top(1) Nip,NewPosition, ApprovedDate
from (
select Nip,NewPosition,ApprovedDate
, grp = row_number() over(order by ApprovedDate desc) - row_number() over(partition by NewPosition order by ApprovedDate desc)
from HistoryPosition
) t
where grp = 0
order by ApprovedDate
)z on z.Nip = a.Nip
where a.flag = 1
and h.AreaCode like '%%'
and Periode like '%CO-2016-9-16-15%'
and tanggal <= k.[to] and tanggal >= k.[from] order by i.Description asc) nilai
pivot ( sum(nilai) for row in ([1],[2],[3],[4],[5]) ) piv)A order by Area;
i get this.

Answer 1

Your last script retrievs the row with the minimum ApprovedDate. It should be effectively the same as
SELECT ApprovedDate, NewPosition
FROM (
SELECT ROW_NUMBER() OVER (PARTITION BY NewPosition ORDER BY ApprovedDate asc) AS rownumber, ApprovedDate, NewPosition
FROM historyposition
WHERE nip = '1004863') t
WHERE rownumber = 1
Try to use this snippet in your bigger query.
EDIT
Detect first group of NewPosition when historyposition is odered by ApprovedDate desc and take first row witn min ApprovedDate in group.
with HistoryPosition as(
-- sample data
select sKodeMutasiP,OldPosition,NewPosition,ApprovedBy
,cast(ApprovedDate as DATE) ApprovedDate, Nip,KodePenilaian
from (
values
('HP0000514','P007','P007',0802678,'2016-09-15',1004863,'PE0000787')
,('HP0000513','P007','P007',0802678,'2016-04-04',1004863,'PE0000130')
,(NULL,NULL,'P007',NULL,'2016-04-04',1004863,NULL)
,(NULL,NULL,'P041',NULL,'2016-01-20',1004863,NULL)
,(NULL,NULL,'P007',NULL,'2015-02-12',1004863,NULL)
) t (sKodeMutasiP,OldPosition,NewPosition,ApprovedBy,ApprovedDate,Nip,KodePenilaian)
)
select top(1) NewPosition, ApprovedDate
from (
select NewPosition,ApprovedDate
, grp = row_number() over(order by ApprovedDate desc) - row_number() over(partition by NewPosition order by ApprovedDate desc)
from HistoryPosition
where nip = 1004863
) t
where grp = 0
order by ApprovedDate;
EDIT2
Use this snippet in OUTER APPLY instead of LEFT JOIN as it depends on other table data:
...
outer apply(
select top(1) NewPosition, ApprovedDate
from (
select NewPosition,ApprovedDate
, grp = row_number() over(order by ApprovedDate desc) - row_number() over(partition by NewPosition order by ApprovedDate desc)
from HistoryPosition hp
where hp.nip = a.nip -- other table
) t
where grp = 0
order by ApprovedDate
) npa
...

If your question is, how can I combine two result sets so that they appear in a single row, the following select can be used:
-- first select
select 1 one, 2 two, 3 three, 0 joinCondition
-- second select
select 'a' a, 'b' b, 'c' c, 0 joinCondition
-- combined
select one, two, three, a, b, c
from (select 1 one, 2 two, 3 three, 0 joinCondition) first
inner join (select 'a' a, 'b' b, 'c' c, 0 joinCondition) second
on first.joinCondition = second.joinCondition
The idea is, we add a dummy column to both selects with equal value so that it can be used to join them
