I know my question is not very logical but I have the folowing chalenge:
HeadTab (Uniq_Id N(10)
Name C(30)
Tax N(18,2))
TrsTab (Uniq_Id N(10)
MonthlyDesc C(20)
Amount N(18,2))
What I want is the following select * from headtab inner join Trstab on uniq_id = Uniq_id
the issue is that I want to see the tax field only once per name other related should be 0...(Eventhough I have many lines in the details tab).
Thank you for any help
If you give the query a row number to determine the first row for each Name you can use a case statement to select which value you want for Tax.
SELECT
ht.Uniq_ID,
ht.NAME,
(CASE WHEN ROW_NUMBER() OVER (PARTITION BY ht.NAME ORDER BY ht.Uniq_ID) = 1 THEN ht.Tax ELSE 0 END) Tax,
tt.*
FROM
headtab ht
INNER JOIN Trstab tt ON ht.uniq_id = tt.Uniq_id

I'm wondering if there is a way to have a complete select statement and if no row is returned to return a row with a default value in a specific field (SQL Server)? Here's a generic version of my SQL to better explain:
SELECT COUNT(CASE WHEN CAST(c.InjuryDate as DATE)>DATEADD(dd,-60, getdate ()) THEN b.InjuryID end) InjuryCount, a.PersonID
FROM Person_Info a
JOIN Injury_Subject b on b.PersonID=a.PersonID
JOIN Injury_Info c on c.InjuryID=b.InjuryID
WHERE EXISTS (SELECT * FROM Hospital_Record d WHERE d.PersonID=b.PersonID and d.InjuryID=b.InjuryID) --There could be multiple people associated with the same InjuryID
GROUP BY a.PersonID
If NOT EXISTS (SELECT * FROM Hospital_Record d WHERE d.PersonID=a.PersonID) THEN '0' in InjuryCount
I want a row for each person who has had an injury to display. Then I'd like a count of how many injuries resulted in hospitalizations in the last 60 days. If they were not hospitalized, I'd like the row to still be generated, but display '0' in InjuryCount column. I've played with this a bunch, moving my date from the WHERE to the SELECT, trying IF ELSE combos, etc. Could someone help me figure out how to get what I want please?
It's hard to tell without an example of input and desired output, but I think this is what you are going for:
select
InjuryCount = count(case
when cast(ii.InjuryDate as date) > dateadd(day,-60,getdate())
then i.InjuryId
else null
end
)
, p.PersonId
from Person_Info p
left join Hosptal_Record h on p.PersonId = h.PersonId
left join Injury_Subject i on i.PersonId = h.PersonId
and h.InjuryId = i.InjuryId
left join Injury_Info ii on ii.InjuryId = i.InjuryId
group by p.PersonId;
I have written a query that returns the list of all customers that have ever made a purchase with the company I work for. The person for whom I am getting the data would like to know if a specific criteria is true for any of these orders.
select L.ParentLocation,
[Number of Orders] = count(distinct(T.Order))
from Table1 L
join Table2 T
on L.Location = T.Location
group by L.ParentLocation
However, the issue is complicated because I am already grouping by ParentLocation, and each ParentLocation has many normal Locations. So I am counting the number of unique orders at the location level, then grouping them by the ParentLocation.
I want to return 'TRUE' in the query if a field 'OrderDesc' contains "Toys" in ANY of the orders by ANY of the Locations owned by a ParentLocation. Is there a way to do this?
NOTE: Table2 contains the OrderDesc column.
Thanks for reading!
select
L.ParentLocation,
[Number of Orders] = count(distinct(T.Order)),
has_toys = max(case when t.OrderDesc like '%toys%' then 'TRUE' else '' end)
from Table1 L
inner join Table2 T
on L.Location = T.Location
group by
L.ParentLocation
SELECT TOP 1000 p.Title,p.Distributor, SUM(r.SalesVolume) AS VolumeOfSales,
CAST(SUM(r.CustomerPrice*r.SalesVolume) as decimal (18,0)) AS ValueOfSales,
CAST (AVG(r.CustomerPrice) as decimal (18,1)) AS AvgPrice,
p.MS_ContentType AS category ,Min(c.WeekId) AS ReleaseWeek
from Product p
INNER JOIN RawData r
ON p.ProductId = r.ProductId
INNER JOIN Calendar c
ON r.DayId = c.DayId
WHERE c.WeekId BETWEEN ('20145231') AND ('20145252')
AND p.Distributor IN ('WARNER', 'TF1', 'GAUMONT')
AND p.VODEST IN ('VOD', 'EST')
AND p.ContentFlavor IN ('SD', 'HD', 'NC')
AND p.MS_ExternalID1 IN ('ADVENTURE/ACTION', 'ANIMATION/FAMILY', 'COMEDY')
AND p.MS_ContentType IN ('FILM', 'TV', 'OTHERS')
AND r.CountryId = 1
GROUP BY p.Title,p.Distributor,p.MS_ContentType
ORDER BY VolumeOfSales DESC, ValueOfSales DESC
I want to madify the above query so that only the column ReleaseWeek is independent of the where clause WHERE c.WeekId BETWEEN ('20145231') AND ('20145252')
The result that I dervive looks like:
`Title Distributor VolumeOfSales ValueOfSales AvgPrice category ReleaseWeek
Divergente M6SND 94038 450095 4.0 Film 20145233`
However what I really want is the ReleaseWeek to be the first value in the column c.WeekId corresponding to that Titlein the database and not the first one between ('20145231') AND ('20145252') What is the best way to modify it? Any leads would be greatful.
This is a query that I've been using:
select serial_number, DAQ.qtag_no, min(TOH.start_time), order_number, DAQ.creation_time, qtag_status, ar_code, pro_foundin, pro_category, root_cause, remark from UNIT U
left JOIN WORK_ORDER WO ON WO.order_key = U.order_key
left join TRACKED_OBJECT_HISTORY TOH on TOH.tobj_key = U.unit_key
WHERE U.creation_time > '01/01/2012' AND U.creation_time < '07/20/2012'
AND order_number NOT LIKE '[R]%'
group by serial_number, qtag_no, order_number, DAQ.creation_time, qtag_status, ar_code, pro_foundin, pro_category, root_cause, remark
order by serial_number
Right now I get 3280 results.
In this setup, there are different stations, such as "Assembly," "Diagnostics," etc. My goal for the min(TOH.start_time) column is to return the first start time at the Assembly station, but currently it's returning the first start time at ANY station. However, if I add another WHERE clause to specify the station (TOH.op_name = 'Assembly'), it limits the number of results (down to 2700). I'd like to keep the 3280 results and instead for units not scanned in to the Assembly station, return NULL for min(TOH.start_time) column. I tried using the case function, but that requires me to include TOH.op_name in the group by clause, which I'm not looking for. Thanks!
You should just be able to add your condition to the left join I think, like this:
select serial_number,
DAQ.qtag_no,
min(TOH.start_time),
order_number,
DAQ.creation_time,
qtag_status,
ar_code,
pro_foundin,
pro_category,
root_cause,
remark
from UNIT U
left
JOIN WORK_ORDER WO
ON WO.order_key = U.order_key
left
join TRACKED_OBJECT_HISTORY TOH
on TOH.tobj_key = U.unit_key
and TOH.op_name = 'Assembly'
WHERE U.creation_time > '01/01/2012' AND U.creation_time < '07/20/2012'
AND order_number NOT LIKE '[R]%'
group by serial_number, qtag_no, order_number, DAQ.creation_time, qtag_status, ar_code, pro_foundin, pro_category, root_cause, remark
order by serial_number
I have 2 tables, that look like:
CustomerInfo(CustomterID, CustomerName)
CustomerReviews(ReviewID, CustomerID, Review, Score)
I want to search reviews for a string and return CustomerInfo.CustomerID and CustomerInfo.CustomerName. However, I only want to show distinct CustomerID and CustomerName along with just one of their CustomerReviews.Reviews and CustomerReviews.Score. I also want to order by the CustomerReviews.Score.
I can't figure out how to do this, since a customer can leave multiple reviews, but I only want a list of customers with their highest scored review.
Any ideas?
This is the greatest-n-per-group problem that has come up dozens of times on Stack Overflow.
Here's a solution that works with a window function:
WITH CustomerCTE (
SELECT i.*, r.*, ROW_NUMBER() OVER (PARTITION BY CustomerID ORDER BY Score DESC) AS RN
FROM CustomerInfo i
INNER JOIN CustomerReviews r ON i.CustomerID = r.CustomerID
WHERE CONTAINS(r.Review, '"search"')
)
SELECT * FROM CustomerCTE WHERE RN = 1
ORDER BY Score;
And here's a solution that works more broadly with RDBMS brands that don't support window functions:
SELECT i.*, r1.*
FROM CustomerInfo i
INNER JOIN CustomerReviews r1 ON i.CustomerID = r1.CustomerID
AND CONTAINS(r1.Review, '"search"')
LEFT OUTER JOIN CustomerReviews r2 ON i.CustomerID = r2.CustomerID
AND CONTAINS(r1.Review, '"search"')
AND (r1.Score < r2.Score OR r1.Score = r2.Score AND r1.ReviewID < r2.ReviewID)
WHERE r2.CustomerID IS NULL
ORDER BY Score;
I'm showing the CONTAINS() function because you should be using the fulltext search facility in SQL Server, not using LIKE with wildcards.
I voted for Bill Karwin's answer, but I thought I'd throw out another option.
It uses a correlated subquery, which can often incur performance problems with large data sets, so use with caution. I think the only upside is that the query is easier to immediately understand.
select *
from [CustomerReviews] r
where [ReviewID] =
(
select top 1 [ReviewID]
from [CustomerReviews] rInner
where rInner.CustomerID = r.CustomerID
order by Score desc
)
order by Score desc
I didn't add the string search filter, but that can be easily added.
I think this should do it
select ci.CustomterID, ci.CustomerName, cr.Review, cr.Score
from CustomerInfo ci inner join
(select top 1*
from CustomerReviews
where Review like '%search%'
order by Score desc) cr on ci.CustomterID = cr.CustomterID
order by cr.Score
