I have a view created in SQL Server Management Studio that brings in certain data, I need to only select the rows with the minimum sequence. For example, in the screenshot see the job number "50773-4", I would only need to see the row with SEQ number 2. I've tried to Group by Min, but to no avail. Any help would be appreciated.
SELECT
TOP (100) PERCENT dbo.Job_Operation.Job,
MIN(dbo.Job_Operation.Sequence) AS SEQ,
dbo.Job_Operation.Work_Center,
dbo.Work_Center.Department
FROM
dbo.Job_Operation
INNER JOIN dbo.Job ON dbo.Job_Operation.Job = dbo.Job.Job
INNER JOIN dbo.User_Values ON dbo.Job.User_Values = dbo.User_Values.User_Values
INNER JOIN dbo.Work_Center ON dbo.Job_Operation.Work_Center = dbo.Work_Center.Work_Center
GROUP BY
dbo.Job_Operation.Job,
dbo.User_Values.Numeric2,
dbo.Work_Center.UVText4,
dbo.Job.Status,
dbo.Job_Operation.Status,
dbo.User_Values.Decimal1,
dbo.Job_Operation.Work_Center,
dbo.Work_Center.Department
HAVING
(dbo.Work_Center.UVText4 = 'Machining')
ORDER BY
dbo.User_Values.Decimal1 DESC,
SEQ
[enter image description here]
I would try the RANK() window function. Perhaps:
SELECT column1,
column2,
rank() OVER (PARTITION BY job ORDER BY seq) AS seq_by_job
Then use this as a nested statement, and filter on only the min rank (i.e. WHERE nested_statement.seq_by_job = 1)
here is one way :
SELECT
TOP (100) PERCENT Job,
Sequence AS SEQ,
Work_Center,
Department
FROM
( select dbo.Job_Operation.Job,
dbo.Job_Operation.Sequence,
dbo.Job_Operation.Work_Center,
dbo.Work_Center.Department,
dbo.User_Values.Decimal1 ,
ROW_NUMBER() over (partition by dbo.Job_Operation.Job,
dbo.User_Values.Numeric2,
dbo.Work_Center.UVText4,
dbo.Job.Status,
dbo.Job_Operation.Status,
dbo.User_Values.Decimal1,
dbo.Job_Operation.Work_Center,
dbo.Work_Center.Department
Order by dbo.Job_Operation.Sequence asc) rn
FROM
dbo.Job_Operation
INNER JOIN dbo.Job ON dbo.Job_Operation.Job = dbo.Job.Job
INNER JOIN dbo.User_Values ON dbo.Job.User_Values = dbo.User_Values.User_Values
INNER JOIN dbo.Work_Center ON dbo.Job_Operation.Work_Center = dbo.Work_Center.Work_Center
) tt
WHERE rn = 1
and UVText4 = 'Machining'
You can do:
with
q as (
SELECT
dbo.Job_Operation.Job,
MIN(dbo.Job_Operation.Sequence) AS SEQ,
dbo.Job_Operation.Work_Center,
dbo.Work_Center.Department,
dbo.User_Values.Decimal1
FROM
dbo.Job_Operation
INNER JOIN dbo.Job ON dbo.Job_Operation.Job = dbo.Job.Job
INNER JOIN dbo.User_Values
ON dbo.Job.User_Values = dbo.User_Values.User_Values
INNER JOIN dbo.Work_Center
ON dbo.Job_Operation.Work_Center = dbo.Work_Center.Work_Center
GROUP BY
dbo.Job_Operation.Job,
dbo.User_Values.Numeric2,
dbo.Work_Center.UVText4,
dbo.Job.Status,
dbo.Job_Operation.Status,
dbo.User_Values.Decimal1,
dbo.Job_Operation.Work_Center,
dbo.Work_Center.Department
HAVING
(dbo.Work_Center.UVText4 = 'Machining')
),
r as (
select *,
row_number() over(partition by job order by seq) as rn
from q
)
select job, seq, work_center, department
from r
where rn = 1
order by Decimal1 DESC

I have select query :
select
f.FirmaID,f.FirmaAdi,t.BelgeID,t.BelgeTuru,t.Tarih,t2.Plaka,t2.SasiNo,t4.AracMarka,t4.AracTip,case when x.Miktar=1 then 4 else x.miktar end as LastikAdet,
t3.CariKodu,t3.CariAdi,t3.CariGsm1,t3.CariGsm2,t3.CariTel1,t3.CariTel2,t3.CariAdres
from alsatr t WITH (NOLOCK)
left join Firma f WITH (NOLOCK) on f.FirmaID = t.AlsatrFirmaID
left join AracBilgi t2 WITH (NOLOCK) on t2.AracBilgiUID = t.AsAracBilgiUID and t2.AracBilgiID= t.AracBilgi
left join Cari t3 WITH (NOLOCK) on t.AsCariUID= t3.CariUID
left join Araclar t4 WITH (NOLOCK) on t4.AracID= t2.AB_AracID
outer apply
(select COUNT(1) soktak,Miktar FROM alsatD d WITH (NOLOCK)
where
d.AlsatDUID = t.AlsatrUID and d.AsStokKodu='LA-0001' group by Miktar) x
where
isnull(t3.FiloID,0) > 0
and t.Tarih between '04.30.2020' and '04.31.2020'
and t.BelgeTuru=55
and x.soktak > 0
and f.FirmaID not in (1,2,103,106,109,114)
order by t.Tarih desc, f.FirmaID desc, t.BelgeID desc
So I want to select all records between two days but I want to select one,latest record (maybe depends on last BelgeID ) on same day with same plate (plaka).
Enclose your query inside a CTE and use ROW_NUMBER() window function:
WITH cte AS (
<your query here>
)
SELECT
t.FirmaID, t.FirmaAdi, t.BelgeID, t.BelgeTuru, t.Tarih, t.Plaka, t.SasiNo, t.AracMarka,
t.AracTip, t.LastikAdet, t.CariKodu, t.CariAdi, t.CariGsm1, t.CariGsm2, t.CariTel1,
t.CariTel2, t.CariAdres
FROM (
SELECT *, ROW_NUMBER() OVER (PARTITION BY Tarih, Plaka ORDER BY BelgeID DESC) rn
FROM cte
) t
WHERE t.rn = 1
Hi I'm trying to hide the TotalRank Column that gets displayed during my results because I only needed it in this query to help sort items. I don't need this information displayed.
SELECT TOP 15 G.CharacterName, G.JobCode, G.PvPExp, D.PVPWin, D.PVPLose, D.PVPGiveUp, RANK() OVER (ORDER BY TotalRank ASC ) as TotalRank
FROM PvPRanking as G
INNER JOIN PVPScores as D
ON G.CharacterID = D.CharacterID
You can use th following
SELECT TOP 15 G.CharacterName, G.JobCode, G.PvPExp, D.PVPWin, D.PVPLose, D.PVPGiveUp
FROM PvPRanking as G
INNER JOIN PVPScores as D
ON G.CharacterID = D.CharacterID
ORDER BY RANK() OVER (ORDER BY TotalRank ASC )
You can create and alias to the resulting table and select everything from it except for the total rank column.
SELECT t1.CharacterName, t1.JobCode, t1.PvPExp, t1.PVPWin, t1.PVPLose, t1.PVPGiveUp
FROM
(SELECT TOP 15 G.CharacterName, G.JobCode, G.PvPExp, D.PVPWin, D.PVPLose, D.PVPGiveUp,
RANK() OVER (ORDER BY TotalRank ASC ) as TotalRank
FROM PvPRanking as G
INNER JOIN PVPScores as D
ON G.CharacterID = D.CharacterID) AS t1
I have 3 tables and trying to get the data out without having many duplicates. Please check on the image that I sent. This is the desired result. Thanks.
I tried:
EDIT:
All this does is Grab all records from Parts then all the records from Assemblies then all the records in Materials. So the return records is HUGE. Here is the standard SQL Statement that connects these tables together.
SELECT impPartID, impShortDescription, uimpConfigPartID as ConfigID,
imaPartID, immPartID FROM Parts
Left Outer Join PartAssemblies on IMAMETHODID = IMPPARTID and
IMAPARENTASSEMBLYID = 0
Left Outer Join PartMaterials on IMMMETHODID = IMPPARTID and
IMMMETHODASSEMBLYID = 0
So I tried this
Select p.impPartID, p.impShortDescription, p.uimpConfigPartID as ConfigID,
a.imaPartID as Assem, m.immPartID as Materials
from (select p.*, row_number() over (order by (select null)) as seqnum
from parts p where uimpConfigPartID <> ''
) p full join
(select a.*, row_number() over (order by (select null)) as seqnum
from assemblies a
) a
on a.IMAMETHODID = p.impPartID and a.seqnum = p.seqnum full join
(select m.*, row_number() over (order by (select null)) as seqnum
from materials m
) m
on m.IMMMETHODID = coalesce(a.IMAMETHODID, p.impPartID) and
m.seqnum = coalesce(a.seqnum, p.seqnum)
One method uses row_number(), union all and group by:
select p.partid, a.descassembly, m.descmaterial
from (select p.*, row_number() over (order by (select null)) as seqnum
from parts p
) p full join
(select a.*, row_number() over (order by (select null)) as seqnum
from assemblies a
) a
on a.partid = p.partid and a.seqnum = p.seqnum full join
(select m.*, row_number() over (order by (select null)) as seqnum
from materials m
) a
on m.partid = coalesce(a.partid, p.partid) and
m.seqnum = coalesce(a.seqnum, p.seqnum);
JOIN public.match m ON (s.stadium_id = m.stadium_id)
group
AS (
)
SELECT round_number
,stadium_name
,spectators
FROM (
SELECT round_number
,stadium_name
,spectators
,RANK() OVER (
PARTITION BY round_number ORDER BY spectators DESC
) AS rank1
FROM t1
) AS s1
WHERE rank1 = 1
<br>
Any smaller query than this?
I think you can just use window functions:
select ms.*
from (select m.round_number, s.stadium_name, m.no_spectators,
row_number() over (partition by m.round_number order by m.no_spectators desc) as seqnum
from public.stadium s join
public.match m
on s.stadium_id = m.stadium_id
) ms
where seqnum = 1
order by m.round_number;
I don't see why aggregation would be needed for the inner query.
You can use a subquery to get the max first
select m.round_number, s.stadium_name, MaxSpec
from public.stadium s
JOIN public.match m ON (s.stadium_id = m.stadium_id)
JOIN
(
select m.round_number, MAX(m.no_spectators) as MaxSpec
from public.stadium s
JOIN public.match m ON (s.stadium_id = m.stadium_id)
group by m.round_number
)a on m.no_spectators = a.MaxSpec
Just one more way to skin this cat. Throw your MAX(no_spectators) into a WHERE clause.
SELECT
m.round_number,
s.stadium_name,
m.no_spectators
FROM
PUBLIC.stadium s
JOIN
PUBLIC.match m
ON s.stadium_id = m.stadium_id
WHERE
m.no_spectators = (SELECT MAX(no_spectators) FROM PUBLIC.match);
That should do for an intro class.
I have the following View which seems to work quickly enough but when I look at the Execution Plan, it shows the Top N Sort in the second query taking ~90% due to it being repeated for every row in the first query.
Should I be adding an Index to the Loan table to help the ORDER BY clause?
CREATE VIEW [dbo].[ResourceItemStatus] AS
SELECT
i.ID AS ItemID,
i.ResourceID,
i.DateAdded,
i.LocationID,
i.OwnerID,
i.Barcode,
i.MissingReasonID,
i.DateRemoved,
ll.PatronID,
ll.ID AS LoanID,
ll.IssueDateTime,
ll.DueDate,
ll.ReturnDateTime,
ll.LoanTypeID,
ll.RenewalCount,
ll.DeleteSummary,
ll.ReturnStatusID,
ll.FineID,
(SELECT COUNT(*) FROM Loan WHERE Loan.ItemID = i.ID) AS LoanCount,
(SELECT COUNT(*) FROM Item WHERE Item.DateRemoved IS NULL AND Item.ResourceID = i.ResourceID) AS AvailableItemCount
FROM Item i
OUTER APPLY
(
SELECT TOP 1
l.ID,
l.ItemID,
l.PatronID,
l.IssueDateTime,
l.DueDate,
l.ReturnDateTime,
l.LoanTypeID,
l.RenewalCount,
l.DeleteSummary,
l.ReturnStatusID,
l.FineID
FROM Loan l
WHERE l.ItemID = i.ID
ORDER BY l.IssueDateTime DESC, l.ID DESC
) AS ll
Try Windowed Aggregates instead of Scalar Subqueries/Outer Apply:
SELECT
i.ID AS ItemID,
i.ResourceID,
i.DateAdded,
i.LocationID,
i.OwnerID,
i.Barcode,
i.MissingReasonID,
i.DateRemoved,
ll.PatronID,
ll.ID AS LoanID,
ll.IssueDateTime,
ll.DueDate,
ll.ReturnDateTime,
ll.LoanTypeID,
ll.RenewalCount,
ll.DeleteSummary,
ll.ReturnStatusID,
ll.FineID,
coalesce(ll.LoanCount, 0)
COUNT(case when Item.DateRemoved IS NULL then 1 end)
over (partition by ResourceID) AS AvailableItemCount
FROM Item i
LEFT JOIN
(
SELECT
l.ID,
l.ItemID,
l.PatronID,
l.IssueDateTime,
l.DueDate,
l.ReturnDateTime,
l.LoanTypeID,
l.RenewalCount,
l.DeleteSummary,
l.ReturnStatusID,
l.FineID,
COUNT(*) over (partition by ItemId) AS LoanCount,
row_number()
over (partition by ItemId
order by l.IssueDateTime DESC, l.ID DESC) as rn
FROM Loan l
) as ll
on ll.ItemID = i.ID
and ll.rn = 1
