I am attempting to do a subquery which should work but I am missing something in the syntex.
I am trying:
select *
from (select * from (select *, row_number() over (partition by number,system order by number,system) as rc from [dbo].[info]) tk0 where tk0.rc =1) tkt
inner join [dbo].[QUEUES] pq
on pq.[QUEUE_NAME] = tkt.[QueueName] inner join [dbo].PLATFORMS] pl
on pl.id = pq.platform_id
and I get incorrect syntax near inner.
This works:
select *, row_number() over (partition by number,system order by number,system) as rc from [dbo].[info]) tk0 where tk0.rc =1
just missing a [ in platforms line .The below should work:
select *
from
(
select *
from
(
select
*, row_number() over (partition by number,system order by number,system) as rc
from [dbo].[info]
) tk0
where tk0.rc =1
) tkt
inner join [dbo].[QUEUES] pq
on pq.[QUEUE_NAME] = tkt.[QueueName]
inner join [dbo].[PLATFORMS] pl --correction done here
on pl.id = pq.platform_id
also you can write your where clause in join too:
select *
from
(
select
*, row_number() over (partition by number,system order by number,system) as rc
from [dbo].[info]
) tkt
inner join [dbo].[QUEUES] pq
on pq.[QUEUE_NAME] = tkt.[QueueName] and tkt.rc =1
inner join [dbo].[PLATFORMS] pl
on pl.id = pq.platform_id

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 a lenghtly query that can be shorten with the correct functionally (I beleive). Can we use existing functions such as Max Min Keep to make this query more efficient? My entire query is posted below.
For example: Can we remove the CTEs and use analytical functions such as max and min This would also elimate ranks and several joins

The following code gives me multiple lines since there can be more than one Cust_Edit_Log.Edit_Timestamp per Alarm Account. There is no other way for a duplicate to occur. How do I only get the result with the earliest Cust_Edit_Log.Edit_Timestamp date? Thank you in advance for any help you can provide.
Select

I have this query:
SELECT t_ticket.ticketID, t_ticket.addedDate, t_ticket.question,
t_ticket.code, t_ticket.priority, t_actionTicket.addedDateAction, t_actionTicket.title
FROM t_actionTicket INNER JOIN
t_ticket ON t_actionTicket.ticketID_FK = t_ticket.ticketID INNER JOIN
(SELECT ticketID_FK, MAX(addedDateAction) AS maxDate
FROM t_actionTicket AS t_actionTicket_1
WHERE (t_actionTicket.userID_FK <> #userid)
GROUP BY ticketID_FK) AS b ON t_actionTicket.ticketID_FK = b.ticketID_FK AND t_actionTicket.addedDateAction = b.maxDate
WHERE (t_ticket.supporterID_FK IN
(SELECT supporterID
FROM t_Supporter
WHERE (userID_FK = #userid)))
I want to return just the latest record in t_actionTicket table for each row in t_ticket table that t_actionTicket.userID_FK <> #userid.
but I have this error:
The multi-part identifier "t_actionTicket.userID_FK" could not be
bound.
Problem in your query is
FROM t_actionTicket AS t_actionTicket_1
WHERE t_actionTicket.userID_FK <> #userid -- here
You cannot use t_actionTicket alias name inside inner join select query. You need to use t_actionTicket_1. It is possible only in sub-query
Try this better way of doing it
;WITH cte
AS (SELECT t_ticket.ticketID,
t_ticket.addedDate,
t_ticket.question,
t_ticket.code,
t_ticket.priority,
t_actionTicket.addedDateAction,
t_actionTicket.title,
Row_number()
OVER(
partition BY ticketID_FK
ORDER BY addedDateAction DESC) RN
FROM t_actionTicket
INNER JOIN t_ticket
ON t_actionTicket.ticketID_FK = t_ticket.ticketID
WHERE t_ticket.supporterID_FK IN (SELECT supporterID
FROM t_Supporter
WHERE userID_FK = #userid))
SELECT *
FROM cte
WHERE rn = 1
You can write this logic using row_number() instead of additional nested queries:
SELECT t.ticketID, t.addedDate, t.question, t.code, t.priority,
ta.addedDateAction, ta.title AS Expr1
FROM t_Ticket t INNER JOIN
(SELECT ta.*,
ROW_NUMBER() OVER (PARTITION BY ta.ticketID_FK ORDER BY ta.addedDateAction DESC) as seqnum
FROM t_actionTicket ta
) ta
ON t.ticketId = ta.ticketId_FK and ta.seqnum = 1
WHERE t.supporterID_FK IN (SELECT supporterID
FROM t_Supporter
WHERE userID_FK = #userid
);
Note that table aliases make the query easier to write and to read.
Try this query
SELECT t_ticket.ticketID, t_ticket.addedDate, t_ticket.question,
t_ticket.code, t_ticket.priority, t_actionTicket.addedDateAction, t_actionTicket.title
FROM t_actionTicket
INNER JOIN t_ticket ON t_actionTicket.ticketID_FK = t_ticket.ticketID
INNER JOIN (SELECT ticketID_FK, MAX(addedDateAction) AS maxDate
FROM t_actionTicket AS t_actionTicket_1
WHERE (t_actionTicket_1.userID_FK <> #userid)
GROUP BY ticketID_FK) AS b ON t_actionTicket.ticketID_FK = b.ticketID_FK AND t_actionTicket.addedDateAction = b.maxDate
WHERE (t_ticket.supporterID_FK IN
(SELECT supporterID
FROM t_Supporter
WHERE (userID_FK = #userid)))
It should return some fields from the SystemTable and the LoadStatus column of the latest record in the ProcessHistory table. The relationship is 1 to many:
SELECT ST.[SystemDetailID], ST.[SystemName], LH.LatestLoadStatus
FROM [SystemTable] AS ST
LEFT OUTER JOIN
(
SELECT LHInner.LoadStatus AS LatestLoadStatus, LHInner.SystemDetailID FROM [dbo].[LoadHistory] AS LHInner
WHERE LHInner.LoadHistoryID in
(
SELECT LatestLoadHisotoryID FROM
(
SELECT MAX(LoadHistoryID) as LatestLoadHisotoryID, SystemDetailID FROM [dbo].[LoadHistory]
GROUP BY SystemDetailID
) l
)
) AS LH ON ST.SystemDetailID = LH.SystemDetailID
Thanks,
This is a greatest-n-per-group query.
One Approach
SELECT ST.[SystemDetailID],
ST.[SystemName],
LH.LatestLoadStatus
FROM [SystemTable] AS ST
OUTER APPLY (SELECT TOP 1 *
FROM [dbo].[LoadHistory] LH
WHERE ST.SystemDetailID = LH.SystemDetailID
ORDER BY LoadHistoryID DESC) LH
You can also use row_number
WITH LH
AS (SELECT *,
ROW_NUMBER() OVER (PARTITION BY SystemDetailID
ORDER BY LoadHistoryID DESC) RN
FROM [dbo].[LoadHistory])
SELECT ST.[SystemDetailID],
ST.[SystemName],
LH.LatestLoadStatus
FROM [SystemTable] AS ST
LEFT JOIN LH
ON LH.SystemDetailID = ST.SystemDetailID
AND LH.RN = 1
SELECT ST.[SystemDetailID], ST.[SystemName], LH.LatestLoadStatus
FROM [SystemTable] AS ST
INNER JOIN [dbo].[LoadHistory] AS LH
ON ST.SystemDetailID = LH.SystemDetailID
AND LH.LoadHistoryID IN
(SELECT MAX(LoadHistoryID) as LoadHistoryID
FROM [dbo].[LoadHistory]
GROUP BY SystemDetailID )
