I need to implement two variables for save the data result in a query.
I have he following query:
SELECT * FROM
(SELECT location AS Location, COUNT(*) AS Trucks FROM Truck GROUP BY location) loc
OUTER APPLY
(
SELECT
COUNT(*) AS TotalOfCampaings,
SUM(CASE WHEN cc.campaing_status = 'Complete' THEN 1 ELSE 0 END) AS CampaingsWithCompleteStatus,
SUM(CASE WHEN cc.campaing_status = 'InProcess' THEN 1 ELSE 0 END) AS CampaingsWithInProcessStatus
FROM CampaingControl cc INNER JOIN Truck t ON cc.vin = t.vin
WHERE t.location = loc.location
) stat
This query shows the next table:
|Location|Trucks|TotalOfCampaings|CampaingsWithCompleteStatus|CampaingsWithInProcessStatus
I need to add a column at the end, in the new column i need to get the percent of campaings with complete status, i tried to do something like this:
Percent = (CampaingsWithCompleteStatus / TotalOfCamapings) * 100
But i dont know how to save the values of the query to do that.
Something like this:
SELECT
loc.Location,
loc.Trunks,
stat.TotalOfCampaings,
stat.CampaingsWithCompleteStatus,
stat.CampaingsWithInProcessStatus,
(1.0 * stat.CampaingsWithCompleteStatus /stat.TotalOfCampaings) * 100 as [Percent]
FROM
(SELECT location AS Location, COUNT(*) AS Trucks FROM Truck GROUP BY location) loc
OUTER APPLY
(
SELECT
COUNT(*) AS TotalOfCampaings,
SUM(CASE WHEN cc.campaing_status = 'Complete' THEN 1 ELSE 0 END) AS CampaingsWithCompleteStatus,
SUM(CASE WHEN cc.campaing_status = 'InProcess' THEN 1 ELSE 0 END) AS CampaingsWithInProcessStatus
FROM CampaingControl cc INNER JOIN Truck t ON cc.vin = t.vin
WHERE t.location = loc.location
) stat

This question already has an answer here:
How to use an Alias in a Calculation for Another Field
(1 answer)
Closed 3 years ago.
In my query below I am counting occurrences in a table based on the Status column. I also want to perform calculations based on the counts I am returning. For example, let's say I want to add 100 to the Snoozed value... how do I do this? Below is what I thought would do it:
SELECT
pu.ID Id, pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END) AS Snoozed,
Snoozed + 100 AS Test
FROM
Prospects p
INNER JOIN
ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE
p.Store = '108'
GROUP BY
pu.Name, pu.Id
ORDER BY
Name
I get this error:
Invalid column name 'Snoozed'.
How can I take the value of the previous SUM statement, add 100 to it, and return it as another column? What I was aiming for is an additional column labeled Test that has the Snooze count + 100.
You can't use one column to create another column in the same way that you are attempting. You have 2 options:
Do the full calculation (as #forpas has mentioned in the comments above)
Use a temp table or table variable to store the data, this way you can get the first 5 columns, and then you can add the last column or you can select from the temp table and do the last column calculations from there.
You can not use an alias as a column reference in the same query. The correct script is:
SELECT
pu.ID Id, pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END)+100 AS Snoozed
FROM
Prospects p
INNER JOIN
ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE
p.Store = '108'
GROUP BY
pu.Name, pu.Id
ORDER BY
Name
MSSQL does not allow you to reference fields (or aliases) in the SELECT statement from within the same SELECT statement.
To work around this:
Use a CTE. Define the columns you want to select from in the CTE, and then select from them outside the CTE.
;WITH OurCte AS (
SELECT
5 + 5 - 3 AS OurInitialValue
)
SELECT
OurInitialValue / 2 AS OurFinalValue
FROM OurCte
Use a temp table. This is very similar in functionality to using a CTE, however, it does have different performance implications.
SELECT
5 + 5 - 3 AS OurInitialValue
INTO #OurTempTable
SELECT
OurInitialValue / 2 AS OurFinalValue
FROM #OurTempTable
Use a subquery. This tends to be more difficult to read than the above. I'm not certain what the advantage is to this - maybe someone in the comments can enlighten me.
SELECT
5 + 5 - 3 AS OurInitialValue
FROM (
SELECT
OurInitialValue / 2 AS OurFinalValue
) OurSubquery
Embed your calculations. opinion warning This is really sloppy, and not a great approach as you end up having to duplicate code, and can easily throw columns out-of-sync if you update the calculation in one location and not the other.
SELECT
5 + 5 - 3 AS OurInitialValue
, (5 + 5 - 3) / 2 AS OurFinalValue
You can't use a column alias in the same select. The column alias do not precedence / sequence; they are all created after the eval of the select result, just before group by and order by.
You must repeat code :
SELECT
pu.ID Id,pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END) AS Snoozed,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END)+ 100 AS Test
FROM
Prospects p
INNER JOIN
ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE
p.Store = '108'
GROUP BY
pu.Name, pu.Id
ORDER BY
Name
If you don't want to repeat the code, use a subquery
SELECT
ID, Name, LeadCount, Working, Uninterested,Converted, Snoozed, Snoozed +100 AS test
FROM
(SELECT
pu.ID Id,pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END) AS Snoozed
FROM Prospects p
INNER JOIN ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE p.Store = '108'
GROUP BY pu.Name, pu.Id) t
ORDER BY Name

I've a table with the following rows of data.
EngID Tower Billing Amt
100 ICS Y 5000
100 EDT Y 7777
100 ICS N 2000
and I want the result set to be consolidated by Tower & Eng ID and the amount put into the appropriate column (Invoiced or Not Invoiced) based on Billing criteria. So, below is how the final result set should look for the above table:
EngID Tower Inv Amt (Amt when Billing = Y) Non-Invoiced Amt (Billing=N)
100 ICS 5000 2000
100 EDT 7777
I'm able to get the 1st row of the result set by using the below query:
Select Temp1.Tower, Temp1. EngID, Temp2.InvoiceAmt as [Inv Amt], Temp1.InvoiceAmt AS [Non-Invoiced Amt] from
(
SELECT EngID, TOWER,BILLING, InvoiceAmt,RANK() OVER (PARTITION BY EngID, TOWER ORDER BY BILLING) AS RNK
FROM [GDF].[dbo].[Sample] ) Temp1 INNER JOIN (SELECT EngID, TOWER,Billing,InvoiceAmt, RANK() OVER (PARTITION BY EngID, TOWER ORDER BY BILLING) AS RNK
FROM [GDF].[dbo].[Sample] ) Temp2 ON
Temp1.EngID = Temp2.EngID
AND (Temp1.Tower = Temp2.Tower AND Temp1.Billing < Temp2.Billing)
However, struggling to get the second row result. My plan is to get the two rows through two separate queries and then do a union to combine the results.
One method is conditional aggregation:
select s.engid, s.tower,
sum(case when s.billing = 'Y' then amt end) as billing_y,
sum(case when s.billing = 'N' then amt end) as billing_n
from gdf.dbo.sample s
group by s.engid, s.tower;
Try this:
select engid, tower,
sum(case when billing = 'Y' then amt end) Inv_amt,
sum(case when billing = 'N' then amt end) Non_Inv_amt,
from my_table
group by
engid,
tower;
We can also do it using OUTER APPLY as below:
select A.EngID,
sum(A.Amt) as [Inv Amt (Amt when Billing = Y)],
sum(B.Amt) as [Non-Invoiced Amt (Billing=N)]
from #test A
outer apply(select b.Amt from #test B where A.EngID = b.EngID and b.tower = a.tower and B.Billing = 'n') B
where a.billing = 'y'
group by A.EngID, A.Tower
Simple LEFT JOIN:
select A.EngID,
sum(A.Amt) as [Inv Amt (Amt when Billing = Y)],
sum(B.Amt) as [Non-Invoiced Amt (Billing=N)]
from #test A
left join #test B on A.EngID = b.EngID
and b.tower = a.tower
and B.Billing = 'n'
where a.billing = 'y'
group by A.EngID, A.Tower
This code will give the desired result without any complexity.Please do find the snapshot of output from below mentioned query.Hope I solved your problem.
WITH Mycte
AS
(
Select ENGID,Tower,Case When Billing='Y' Then ISNULL(SUM(Amt),0) END AS Inv_Amt,
Case When Billing='N' Then ISNULL(SUM(Amt),0) END AS Non_Inv_Amt from #Sample
group by ENGID,Tower,Billing
)
Select ENGID,Tower,SUM(Inv_Amt) AS Inv_Amt,SUM(Non_Inv_Amt) AS Non_Inv_Amt from mycte
group by ENGID,Tower
Promt please.
I have an query: SELECT MAX(FPS.EndDateKey) WHERE FPS.EndDateKey <>-2
I need to receive quantity of lines of this query in other query:
SELECT INVS.ParticipantKey, MIN(CASE WHEN FPS.EndDateKey <> -2 AND FPS.EndDateKey > FPS.DefinedEndDateKey
AND FPS.EndDateKey > #PeriodEndDateKey AND FPS.DefinedEndDateKey < #PeriodEndDateKey
THEN 1
ELSE 0
END) as InRunout,
MAX(CASE WHEN DP.AccountKey = 6 THEN 1 ELSE 0 END) as HasHSA,
MAX(FPS.StartDateKey) as MostCurrentEnrollment,
CASE WHEN EXISTS(SELECT MAX(FPS.EndDateKey) WHERE FPS.EndDateKey <>-2) THEN 1 ELSE 0 END AS CurrentPlanYear
FROM SupportFile.InvoicableSubscription as INVS
INNER JOIN Evolution1.FactProductSubscription as FPS ON FPS.SubscriptionKey = INVS.SubscriptionKey AND FPS.StartDateKey = INVS.StartDateKey
INNER JOIN Evolution1.DimProduct as DP ON DP.ProductKey = FPS.ProductKey
GROUP BY INVS.ParticipantKey, FPS.EndDateKey
How I am able to do it? Prompt please. Thanks
You can achieve this via a subquery:
Psuedo code:
Select Name, description,
(select max(field) from table2) as maxtable2
from table 1
I have a inventory table with a condition i.e. new, used, other, and i am query a small set of this data, and there is a possibility that all the record set contains only 1 or all the conditions. I tried using a case statement, but if one of the conditions isn't found nothing for that condition returned, and I need it to return 0
This is what I've tried so far:
select(
case
when new_used = 'N' then 'new'
when new_used = 'U' then 'used'
when new_used = 'O' then 'other'
end
)as conditions,
count(*) as count
from myDB
where something = something
group by(
case
when New_Used = 'N' then 'new'
when New_Used = 'U' then 'used'
when New_Used = 'O' then 'other'
end
)
This returns the data like:
conditions | count
------------------
new 10
used 45
I am trying to get the data to return like the following:
conditions | count
------------------
new | 10
used | 45
other | 0
Thanks in advance
;WITH constants(letter,word) AS
(
SELECT l,w FROM (VALUES('N','new'),('U','used'),('O','other')) AS x(l,w)
)
SELECT
conditions = c.word,
[count] = COUNT(x.new_used)
FROM constants AS c
LEFT OUTER JOIN dbo.myDB AS x
ON c.letter = x.new_used
AND something = something
GROUP BY c.word;
try this -
DECLARE #t TABLE (new_used CHAR(1))
INSERT INTO #t (new_used)
SELECT t = 'N'
UNION ALL
SELECT 'N'
UNION ALL
SELECT 'U'
SELECT conditions, ISNULL(r.cnt, 0) AS [count]
FROM (
VALUES('U', 'used'), ('N', 'new'), ('O', 'other')
) t(c, conditions)
LEFT JOIN (
SELECT new_used, COUNT(1) AS cnt
FROM #t
--WHERE something = something
GROUP BY new_used
) r ON r.new_used = t.c
in output -
new 2
used 1
other 0
You can do it as a cross-tab:
select
sum(case when new_used = 'N' then 1 else 0 end) as N,
sum(case when new_used = 'U' then 1 else 0 end) as U,
sum(case when new_used = 'O' then 1 else 0 end) as Other
from myDB
where something = something
How can I improve the SQL query below (SQL Server 2008)? I want to try to avoid sub-selects, and I'm using a couple of them to produce results like this
StateId TotalCount SFRCount OtherCount
---------------------------------------------------------
AZ 102 50 52
CA 2931 2750 181
etc...
SELECT
StateId,
COUNT(*) AS TotalCount,
(SELECT COUNT(*) AS Expr1 FROM Property AS P2
WHERE (PropertyTypeId = 1) AND (StateId = P.StateId)) AS SFRCount,
(SELECT COUNT(*) AS Expr1 FROM Property AS P3
WHERE (PropertyTypeId <> 1) AND (StateId = P.StateId)) AS OtherCount
FROM Property AS P
GROUP BY StateId
HAVING (COUNT(*) > 99)
ORDER BY StateId
This may work the same, hard to test without data
SELECT
StateId,
COUNT(*) AS TotalCount,
SUM(CASE WHEN PropertyTypeId = 1 THEN 1 ELSE 0 END) as SFRCount,
SUM(CASE WHEN PropertyTypeId <> 1 THEN 1 ELSE 0 END) as OtherCount
FROM Property AS P
GROUP BY StateId
HAVING (COUNT(*) > 99)
ORDER BY StateId
Your alternative is a single self-join of Property using your WHERE conditions as a join parameter. The OtherCount can be derived by subtracting the TotalCount - SFRCount in a derived query.
Another alternative would be to use the PIVOT function like this:
SELECT StateID, [1] + [2] AS TotalCount, [1] AS SFRCount, [2] AS OtherCount
FROM Property
PIVOT ( COUNT(PropertyTypeID)
FOR PropertyTypeID IN ([1],[2])
) AS pvt
WHERE [1] + [2] > 99
You would need to add an entry for each property type which could be daunting but it is another alternative. Scott has a great answer.
If PropertyTypeId is not null then you could do this with a single join. Count is faster than Sum. But is Count plus Join faster than Sum. The test case below mimics your data. docSVsys has 800,000 rows and there are about 300 unique values for caseID. The Count plus Join in this test case is slightly faster than the Sum. But if I remove the with (nolock) then Sum is about 1/4 faster. You would need to test with your data.
select GETDATE()
go;
select caseID, COUNT(*) as Ttl,
SUM(CASE WHEN mimeType = 'message/rfc822' THEN 1 ELSE 0 END) as SFRCount,
SUM(CASE WHEN mimeType <> 'message/rfc822' THEN 1 ELSE 0 END) as OtherCount,
COUNT(*) - SUM(CASE WHEN mimeType = 'message/rfc822' THEN 1 ELSE 0 END) as OtherCount2
from docSVsys with (nolock)
group by caseID
having COUNT(*) > 1000
select GETDATE()
go;
select docSVsys.caseID, COUNT(*) as Ttl
, COUNT(primaryCount.sID) as priCount
, COUNT(*) - COUNT(primaryCount.sID) as otherCount
from docSVsys with (nolock)
left outer join docSVsys as primaryCount with (nolock)
on primaryCount.sID = docSVsys.sID
and primaryCount.mimeType = 'message/rfc822'
group by docSVsys.caseID
having COUNT(*) > 1000
select GETDATE()
go;
