I'm quite new to SQL and I hope you can help me.
I'm trying to retrieve unique values from my table based on the latest date where specific users are selected.
This is the data:
Raw Data
And this is what I'm looking to achieve:
Desired Data
I tried to write 2 queries but unfortunately:
My 1st query would display duplicated rows for each company:
SELECT DISTINCT FilteredAppointment.regardingobjectidname ,FilteredAppointment.owneridname ,FilteredAppointment.subject ,MAX(FilteredAppointment.scheduledstart) as Date ,FilteredAppointment.location ,FilteredCcx_member.ccx_mnemonic FROM FilteredAppointment INNER JOIN FilteredAccount ON FilteredAppointment.regardingobjectid = FilteredAccount.accountid INNER JOIN FilteredCcx_member ON FilteredAccount.accountid = FilteredCcx_member.ccx_accountid WHERE FilteredAppointment.statecodename != N'Canceled' AND FilteredAppointment.owneridname IN (N'User1', N'User2', N'User3') GROUP BY FilteredAppointment.regardingobjectidname ,FilteredAppointment.owneridname ,FilteredAppointment.subject ,FilteredAppointment.scheduledstart ,FilteredAppointment.location ,FilteredCcx_member.ccx_mnemonic ORDER BY FilteredAppointment.regardingobjectidname
And my 2nd query would display one row only:
SELECT DISTINCT FilteredAppointment.regardingobjectidname ,FilteredAppointment.owneridname ,FilteredAppointment.subject ,FilteredAppointment.scheduledstart ,FilteredAppointment.location ,FilteredCcx_member.ccx_mnemonic FROM FilteredAppointment INNER JOIN FilteredAccount ON FilteredAppointment.regardingobjectid = FilteredAccount.accountid INNER JOIN FilteredCcx_member ON FilteredAccount.accountid = FilteredCcx_member.ccx_accountid WHERE FilteredAppointment.scheduledstart = (SELECT MAX(FilteredAppointment.scheduledstart) FROM FilteredAppointment WHERE FilteredAppointment.regardingobjectidname = FilteredAppointment.regardingobjectidname) AND FilteredAppointment.statecodename != N'Canceled' AND FilteredAppointment.owneridname IN (N'User1', N'User2', N'User3') GROUP BY FilteredAppointment.regardingobjectidname ,FilteredAppointment.owneridname ,FilteredAppointment.subject ,FilteredAppointment.scheduledstart ,FilteredAppointment.location ,FilteredCcx_member.ccx_mnemonic ORDER BY FilteredAppointment.regardingobjectidname
Try this:-
SELECT distinct a.date, a.company, a.companyID, a.User, a.Location, a.topic
FROM tablename a
inner join
(
Select company, companyID, User, max(date) as recent_date
from
tablename
group by company, companyID, User
) b
on a.date=b.recent_date and a.company=b.company and a.companyID=b.companyID
and a.User=b.User;
I managed to solve the issue - Thank you for the help again!
WITH apptmts AS (SELECT TOP 1 WITH TIES fa.scheduledstart,fa.location,fa.regardingobjectidname,mem.ccx_mnemonic,fa.owneridname,fa.subject FROM FilteredAppointment fa JOIN FilteredAccount acc on fa.regardingobjectid = acc.accountid JOIN FilteredCcx_member mem ON acc.accountid = mem.ccx_accountid WHERE fa.statecodename != N'Canceled' AND fa.owneridname IN (N'User1', N'User2', N'User3') ORDER BY ROW_NUMBER() OVER(PARTITION BY fa.regardingobjectidname ORDER BY fa.scheduledstart DESC) ) SELECT * FROM apptmts ORDER BY scheduledstart DESC

I have an existing query that is picking up the max date of the exdt field per below for every record for that particular item. I'm trying to add an additional MAX calculation to the sqn field, essentially picking up records with the highest exdt and sqn field together. I tried adding an additional "AND (a.sqn = (SELECT MAX(sqn) to the WHERE and it seems to not like multiple selects.
SELECT a.item, a.cpc, dt.dsc, a.exdt, a.sqn
FROM dbo.ct AS a INNER JOIN dbo.dt ON a.cpc = dt.cpc
WHERE (a.exdt = (SELECT MAX(exdt) AS exdt FROM dbo.ct AS a
Any help would be appreciated!
Thanks.
The script to get records having max of both fields is the following
SELECT a.item, a.cpc, dt.dsc, a.exdt, a.sqn
FROM dbo.ct AS a INNER JOIN dbo.dt ON a.cpc = dt.cpc
WHERE
a.exdt = (SELECT MAX(exdt) AS exdt FROM dbo.ct )
and
a.sqn= (SELECT MAX(sqn) AS exdt FROM dbo.ct)
You can also use CTEas follows
with
cte_principal as
(SELECT a.item, a.cpc, dt.dsc, a.exdt, a.sqn
FROM dbo.ct AS a INNER JOIN dbo.dt ON a.cpc = dt.cpc),
cte_max_exdt as (SELECT MAX(exdt) AS exdt FROM dbo.ct),
cte_max_sqn as (SELECT MAX(sqn) AS exdt FROM dbo.ct)
select p.* from cte_principal p
inner join cte_max_exdt on p.exdt =cte_max_exdt.exdt
inner join cte_max_sqn pn p.sqn=cte_max_sqn.sqn
Perhaps you need subquery which is going to find max date for each item.
That is ct_max_date in my case
After that you join that subquery by max_date and item_Id
SELECT a.item, a.cpc, dt.dsc, a.exdt, a.sqn
FROM dbo.ct AS a
INNER JOIN dbo.dt ON a.cpc = dt.cpc
inner join (
select max(exdt) as max_date, ct.cpc
from dbo.ct
group by ct.dt
) as ct_max_date on a.cpc=ct_max_date.cpc and a.exdt=ct_max_date.max_date
SELECT
tblEmployeeMaster.TeamName, SUM(tblData.Quantity) AS 'TotalQuantity'
FROM
tblData
INNER JOIN
tblEmployeeMaster ON tblData.EntryByHQCode = tblEmployeeMaster.E_HQCode
INNER JOIN
tblPhotos ON tblEmployeeMaster.TeamNo = tblPhotos.TeamNo
WHERE
IsPSR = 'Y'
GROUP BY
tblPhotos.TeamSort, tblPhotos.TeamNo, tblPhotos.Data,
tblEmployeeMaster.TeamName
ORDER BY
tblPhotos.TeamSort DESC, TotalQuantity DESC
This returns
Using this statement
select TeamName, count(TeamName) AS 'Head Count'
from dbo.tblEmployeeMaster
where IsPSR = 'Y'
group by teamname
Which returns
I would like to combine these 2 queries in 1 to get the below result.
Tried union / union all but no success :(
Any help will be very much helpful.
You can simply use the sub-query as follows:
SELECT tblEmployeeMaster.TeamName, SUM(tblData.Quantity) AS 'TotalQuantity',
MAX(HEAD_COUNT) AS HEAD_COUNT, -- USE THIS VALUE FROM SUB-QUERY
CASE WHEN MAX(HEAD_COUNT) <> 0
THEN SUM(tblData.Quantity)/MAX(HEAD_COUNT)
END AS PER_MAN_CONTRIBUTION -- column asked in comment
FROM tblData INNER JOIN
tblEmployeeMaster ON tblData.EntryByHQCode = tblEmployeeMaster.E_HQCode INNER JOIN
tblPhotos ON tblEmployeeMaster.TeamNo = tblPhotos.TeamNo
-- FOLLOWING SUB-QUERY CAN BE USED
LEFT JOIN (select TeamName, count(TeamName) AS HEAD_COUNT
from dbo.tblEmployeeMaster
where IsPSR = 'Y' group by teamname) AS HC
ON HC.TeamName = tblEmployeeMaster.TeamName
where IsPSR = 'Y'
GROUP BY tblPhotos.TeamSort, tblPhotos.TeamNo, tblPhotos.Data,tblEmployeeMaster.TeamName
order by tblPhotos.TeamSort desc, TotalQuantity desc
I am trying to filter cg_group names (please check the query) and group (using: GROUP BY) the results according to last updated opportunity (using: ORDER BY opportunities.date_modified DESC).
When I used query without use group by it returns the following results:
SELECT cg_groups.name
FROM cg_groups
JOIN cg_groups_cstm ON cg_groups_cstm.id_c = cg_groups.id
JOIN accounts_cstm ON cg_groups.name = accounts_cstm.client_group_c
JOIN accounts ON accounts.id = accounts_cstm.id_c
JOIN accounts_opportunities ON accounts.id = accounts_opportunities.account_id
JOIN opportunities ON accounts_opportunities.opportunity_id = opportunities.id
WHERE cg_groups.deleted='0' AND cg_groups_cstm.status_c='1' AND opportunities.deleted='0'
ORDER BY opportunities.date_modified DESC
Results:
ABC Group
ABC Group
CBC Group
ABC Group
XYZ Group
But I want to group this to following order:
ABC Group
CBC Group
XYZ Group
To do that I added GROUP BY cg_groups.name
SELECT cg_groups.name
FROM cg_groups
JOIN cg_groups_cstm ON cg_groups_cstm.id_c = cg_groups.id
JOIN accounts_cstm ON cg_groups.name = accounts_cstm.client_group_c
JOIN accounts ON accounts.id = accounts_cstm.id_c
JOIN accounts_opportunities ON accounts.id = accounts_opportunities.account_id
JOIN opportunities ON accounts_opportunities.opportunity_id = opportunities.id
WHERE cg_groups.deleted='0' AND cg_groups_cstm.status_c='1' AND opportunities.deleted='0'
GROUP BY cg_groups.name
ORDER BY opportunities.date_modified DESC
But now I get this error:
Msg 8127, Level 16, State 1, Line 10
Column "opportunities.date_modified" is invalid in the ORDER BY clause because it is not contained in either an aggregate function or the GROUP BY clause.
Someone please help me to solve this issue, thank you.
Use ROW_NUMBER to find the most recently updated record for each group:
WITH cte AS (
SELECT cg_groups.name, o.date_modified,
ROW_NUMBER() OVER (PARTITION BY o.date_modified DESC) rn
FROM cg_groups cg
INNER JOIN cg_groups_cstm cgc
ON cgc.id_c = cg.id
INNER JOIN accounts_cstm ac
ON cg.name = ac.client_group_c
INNER JOIN accounts a
ON a.id = ac.id_c
INNER JOIN accounts_opportunities ao
ON a.id = ao.account_id
INNER JOIN opportunities o
ON ao.opportunity_id = o.id
WHERE cg.deleted = '0' AND cgc.status_c = '1' AND o.deleted = '0'
)
SELECT name
FROM cte
WHERE rn = 1
ORDER BY date_modified DESC;
Note that this may not be exactly what you want. This answer returns a single record per name group which is the most recently updated for that group. It then orders all results descending, but maybe you want ascending.
put opportunities.date_modified in selection and group by then you can use that in order by
SELECT opportunities.date_modified,cg_groups.name
FROM cg_groups
JOIN cg_groups_cstm ON cg_groups_cstm.id_c = cg_groups.id
JOIN accounts_cstm ON cg_groups.name = accounts_cstm.client_group_c
JOIN accounts ON accounts.id = accounts_cstm.id_c
JOIN accounts_opportunities ON accounts.id = accounts_opportunities.account_id
JOIN opportunities ON accounts_opportunities.opportunity_id = opportunities.id
WHERE cg_groups.deleted='0' AND cg_groups_cstm.status_c='1' AND opportunities.deleted='0'
GROUP BY cg_groups.name,opportunities.date_modified
ORDER BY opportunities.date_modified DESC
but for your result you can try like below just use distinct
SELECT distinct cg_groups.name
FROM cg_groups
JOIN cg_groups_cstm ON cg_groups_cstm.id_c = cg_groups.id
JOIN accounts_cstm ON cg_groups.name = accounts_cstm.client_group_c
JOIN accounts ON accounts.id = accounts_cstm.id_c
JOIN accounts_opportunities ON accounts.id = accounts_opportunities.account_id
JOIN opportunities ON accounts_opportunities.opportunity_id = opportunities.id
WHERE cg_groups.deleted='0' AND cg_groups_cstm.status_c='1' AND opportunities.deleted='0'
order by cg_groups.name
no group by need as you have not used any aggregate function
how about just adding distinct right after your SELECT statement .
Select distinct ... from ...
I need to select reviews for product, but unique by user (i.e. one review from user).
With my code, I select all reviews, and I can see few reviews left by one user.
SELECT
tr.reviewText, tr.reviewDate, tr.reviewRating,
u.userName AS userName,
u.userFirstName AS userFirstName, u.userSurname AS userSurname,
u.countryId AS countryId
FROM
tblReviews tr
INNER JOIN
tblOrderProduct op ON op.orderProductId = tr.orderProductId
AND op.productOptionId IN (SELECT productOptionId
FROM tblProductOption
WHERE productSubCuId = 111
AND productOptionActive = 1)
LEFT JOIN
tblOrder o ON o.orderId = op.orderId
LEFT JOIN
tblUser u ON u.userRandomId = o.userRandomId
WHERE
tr.reviewsStatusId = 2
ORDER BY
tr.reviewRating DESC, tr.reviewDate DESC
OFFSET 0 ROWS FETCH NEXT 100 ROWS ONLY
Can I get just one review from each user?
Maybe I need select userId -> group results by userId and select one per group? [I tried to do so, but I didn't succeed :( ]
You can use row_number to number the reviews and select any one like below:
;with per_user_one_review
as
(SELECT tr.reviewText, tr.reviewDate, tr.reviewRating,
u.userName as userName,
u.userFirstName as userFirstName, u.userSurname as userSurname,
u.countryId as countryId, row_number() over (partition by u.userRandomId order by tr.reviewDate desc) rn
FROM tblReviews tr
INNER JOIN tblOrderProduct op
ON op.orderProductId = tr.orderProductId
AND op.productOptionId IN (
SELECT productOptionId FROM tblProductOption
WHERE productSubCuId = 111 AND productOptionActive = 1
)
LEFT JOIN tblOrder o ON o.orderId = op.orderId
LEFT JOIN tblUser u ON u.userRandomId = o.userRandomId
WHERE tr.reviewsStatusId = 2
ORDER BY tr.reviewRating DESC, tr.reviewDate DESC
OFFSET 0 ROWS FETCH NEXT 100 ROWS ONLY
)
select * from per_user_one_review where rn = 1
It will pick the latest review (reviewDate desc) from the user.
If you need the last review you could use a join with the suquery for max review date grouped by orderProductId
(and as a suggestion you could use a inner join instead of a IN clasue based on a subquery)
select tr.reviewText
, tr.reviewDate
, tr.reviewRating
, u.userName
, u.userFirstName
, u.userSurname
, u.countryId
from tblReviews tr
INNER JOIN (
select max(reviewDate) max_date, orderProductId
from tblReviews
group by orderProductId
) t1 on t1.orderProductId = tr.orderProductId and t1.max_date = tr.reviewDate
INNER JOIN tblOrderProduct op ON op.orderProductId = tr.orderProductId
INNER JOIN (
SELECT productOptionId
FROM tblProductOption
WHERE productSubCuId = 111 AND productOptionActive = 1
) t2 ON op.productOptionId = t2.productOptionId
LEFT JOIN tblOrder o ON o.orderId = op.orderId
LEFT JOIN tblUser u ON u.userRandomId = o.userRandomId
WHERE tr.reviewsStatusId = 2
ORDER BY tr.reviewRating DESC, tr.reviewDate DESC
OFFSET 0 ROWS FETCH NEXT 100 ROWS ONLY

I have seen a few threads about this topic but I can't find one that involves multiple joins in the query. I can't create a VIEW on this database so the joins are needed.
The Query
SELECT
p.Price
,s.Type
,s.Symbol
, MAX(d.Date) Maxed
FROM AdventDW.dbo.FactPrices p
INNER JOIN dbo.DimSecurityMaster s
ON s.SecurityID = p.SecurityID
INNER JOIN dbo.DimDateTime d
ON
p.DateTimeKey = d.DateTimeKey
GROUP BY p.Price ,
s.Type ,
s.Symbol
ORDER BY s.Symbol
The query works but does not produce distinct results. I am using Order by to validate the results, but it is not required once I get it working. I The result set looks like this.
Price Type Symbol Maxed
10.57 bfus *bbkd 3/31/1989
10.77 bfus *bbkd 2/28/1990
100.74049 cbus 001397AA6 8/2/2005
100.8161 cbus 001397AA6 7/21/2005
The result set I want is
Price Type Symbol Maxed
10.77 bfus *bbkd 2/28/1990
100.74049 cbus 001397AA6 8/2/2005
Here were a few other StackOverflow threads I tried but couldn't get t work with my specific query
How can I SELECT rows with MAX(Column value), DISTINCT by another column in SQL?
SQL Selecting distinct rows from multiple columns based on max value in one column
If you want data for the maximum date, use row_number() rather than group by:
SELECT ts.*
FROM (SELECT p.Price, s.Type, s.Symbol, d.Date,
ROW_NUMBER() OVER (PARTITION BY s.Type, s.Symbol
ORDER BY d.Date DESC
) as seqnum
FROM AdventDW.dbo.FactPrices p INNER JOIN
dbo.DimSecurityMaster s
ON s.SecurityID = p.SecurityID INNER JOIN
dbo.DimDateTime d
ON p.DateTimeKey = d.DateTimeKey
) ts
WHERE seqnum = 1
ORDER BY s.Symbol;
You should use a derived table since you really only want to group the DateTimeKey table to get the MAX date.
SELECT p.Price ,
s.Type ,
s.Symbol ,
tmp.MaxDate
FROM AdventDW.dbo.FactPrices p
INNER JOIN dbo.DimSecurityMaster s ON s.SecurityID = p.SecurityID
INNER JOIN
( SELECT MAX(d.Date) AS MaxDate ,
d.DateTimeKey
FROM dbo.DimDateTime d
GROUP BY d.DateTimeKey ) tmp ON p.DateTimeKey = tmp.DateTimeKey
ORDER BY s.Symbol;
/*
this is your initial select which is fine because this is base from your original criteria,
I cannot ignore this so i'll keep this in-tact. Instead from here i'll create a temp
*/
SELECT
p.Price
, s.Type
, s.Symbol
, MAX(d.Date) Maxed
INTO #tmpT
FROM AdventDW.dbo.FactPrices p
INNER JOIN dbo.DimSecurityMaster s
ON s.SecurityID = p.SecurityID
INNER JOIN dbo.DimDateTime d
ON p.DateTimeKey = d.DateTimeKey
GROUP BY p.Price ,
s.Type ,
s.Symbol
ORDER BY s.Symbol
SELECT innerTable.Price, innerTable.Symbol, innerTable.Type, innerTable.Maxed
FROM (
SELECT
ROW_NUMBER () OVER (PARTITION BY t1.Symbol, t1.Type, t1.Maxed ORDER BY t1.Maxed DESC) as row
, *
FROM #tmpT AS t1
) AS innerTable
WHERE row = 1
DROP TABLE #tmpT
