In a SQL-Statement I need to query the same column three times with three different conditions.
I need the SUM of CC.HR1*WLL17.Hours displayed for all Locations but with three different conditions. I tried a subquery in the SELECT statement but then I only get the total sum and not the sum grouped by location.
SELECT WLL17.Location, (SELECT SUM(CC.HR1*WLL17.Hours) FROM WLL17 INNER JOIN CC ON WLL17.CC=CC.CC WHERE WLL17.EE = "Post Gate 60 (PV)") AS Plant
FROM WLL17 INNER JOIN CC ON WLL17.CC = CC.CC
WHERE WLL17.CC<>"Outsourced Costs"
GROUP BY WLL17.Location;
Try to follow this strategy.
SELECT WLL17.Location,
SUM(case when WLL17.EE = "Post Gate 60 (PV)" then CC.HR1*WLL17.Hours else null end) AS Plant,
SUM(case when WLL17.CC<>"Outsourced Costs" then CC.HR1*WLL17.Hours else null end) AS Location_Name1,
SUM(case when [Write condition here] then CC.HR1*WLL17.Hours else null end) AS Location_Name2
FROM WLL17 INNER JOIN CC ON WLL17.CC = CC.CC
GROUP BY WLL17.Location;

I am trying to write a query that returns an "Estimated Annual Value", and for this, I am using a Case statement. There are two inner joins involved in the query.
So, the query and gives me result when I am running this piece:
select Users.Id, Name, PhoneNumber, Email, Currency, count(*) as TotalOrders, sum(TotalCustomerAmount) as TotalOrderValue, avg(TotalCustomerAmount) as AverageOrderValue, TsCreate as RegistrationDate, max(TsOrderPlaced) as LastOrderDate, min(TsOrderPlaced) as FirstOrderDate,
CASE
When PromotionsEnabled = 0 then 'Y'
When PromotionsEnabled = 1 then 'n'
else 'undefined'
end as Promotions,
/*CASE
When ((DATEDIFF(day, max(TsOrderPlaced), min(TsOrderPlaced)) >= 6) AND (count(*) > 3)) then ((sum(TotalCustomerAmount)/(DATEDIFF(day, max(TsOrderPlaced), min(TsOrderPlaced))))*365)
Else '-'
end as EstimatedAnnualValue*/
from AspNetUsers with (nolock)
inner join Orders with (nolock) on Orders.UserId = AspNetUsers.Id and Orders.WhiteLabelConfigId = #WhiteLabelConfigId
and Orders.OrderState in (2,3,4,12)
inner join UserWhiteLabelConfigs with (nolock) on UserWhiteLabelConfigs.UserId = AspNetUsers.Id and Orders.WhiteLabelConfigId = #WhiteLabelConfigId
where AspNetUsers.Discriminator = 'ApplicationUser'
group by Users.Id, Name, Number, Currency, Email, TsCreate, PromotionsEnabled
But the problem comes when I am running this with the second CSAE statement, is it because I cannot use the aggregate function before GROUP BY? I am also thinking of using a Subquery
Looking fr some help!!
You need to use aggregation functions. For instance, if you want 'Y' only when all values are 0 or NULL:
(case when max(PromotionsEnabled) = 0 then 'Y'
when max(PromotionsEnabled) = 1 then 'N'
else 'undefined'
end) as Promotions,
I'm not sure if this is the logic you want (because that detail is not in the question). However, this shows that you can use aggregation functions in a case expression.
I am writing a report that needs to show the number of bookings taken for a location with the total value of those bookings.
How do I sum the bookings column and show only one row for the location, that includes the columns set out in the example of expected data?
Select Statement Below:
SELECT
Locations.Description as LocationsDesc,
Locations.LocationGUID,
Venues.VenueName,
Venues.VenueGUID,
count (Bookings.BookingID) as Bookings,
Departments.DepartmentName,
Departments.DepartmentGUID,
sum(SalesTransactionDetails.NetDetailValue) as NetDetailValue,
sum(SalesTransactionDetails.DetailValue) as DetailValue,
SUM(CASE When Salestransactionlines.itemtype = 1 Then SalesTransactionDetails.NetDetailValue Else 0 End ) as RentalFee,
SUM(CASE When Salestransactionlines.itemtype = 2 Then SalesTransactionDetails.NetDetailValue Else 0 End ) as ExtraFee,
SalesTransactions.SalesTransactionGUID
FROM BookingLinesDetails
INNER JOIN Bookings ON BookingLinesDetails.BookingGUID=Bookings.BookingGUID
INNER JOIN Locations ON BookingLinesDetails.LocationGUID=Locations.LocationGUID
INNER JOIN Venues on Venues.Venueguid = Locations.Venueguid
INNER JOIN SalesTransactionDetails ON BookingLinesDetails.BookingLinesDetailGUID=SalesTransactionDetails.BookingLinesDetailGUID
INNER JOIN SalesTransactionLines ON SalesTransactionDetails.SalesTransactionLineGUID=SalesTransactionLines.SalesTransactionLineGUID
INNER JOIN SalesTransactions ON SalesTransactionLines.SalesTransactionGUID=SalesTransactions.SalesTransactionGUID
INNER JOIN Departments on Departments.DepartmentGUID = Locations.DepartmentGUID
WHERE
BookingLinesDetails.StartDateTime >= dbo.InzDateOnly(#pFromDate) and
BookingLinesDetails.StartDateTime < DateAdd(day,1,dbo.inzDateOnly(#pToDate)) and
Departments.DepartmentGUID in (Select GUID from dbo.InzSplitGUID(#DepartmentID)) and
(#IncludeAllLocationGroupsInVenues <> 0 or (#IncludeAllLocationGroupsInVenues = 0 )) and
Venues.VenueGUID in (Select GUID from dbo.InzSplitGUID(#VenueID)) and
salesTransactions.Status = 1 and -- remove cancelled
salestransactions.receiptonly = 0
GROUP BY
Locations.Description,
Locations.LocationGUID,
Venues.VenueName,
Venues.VenueGUID,
Departments.DepartmentName,
Departments.DepartmentGUID,
SalesTransactions.SalesTransactionGUID
The output is currently:
Desired output is:

Location - Deck Room 348A43F12 7DAD77BE 33 Aquatics Centre 2059.46 2162.5 0
I have attempted several versions of Count and sum. I believe I need to make the query a derived table and then select from that, but am not sure how to go about it, even if that is the answer.
Thank you in advance.
I am trying to get the number of customers by their types and groups all in line as such:
GroupName | GroupNotes | Count(Type1) | Count(Type2) | Count(Type3)
but instead I can only get the groupid ,the typeid and the number of types in the group by using the following query
SELECT
CustomersGroups.idCustomerGroup , Customers.type , COUNT(*)
FROM
CustomersGroups
inner Join CustomersInGroup on CustomersGroups.idCustomerGroup = CustomersInGroup.idCustomerGroup
inner Join Customers on Customers.idCustomer = CustomersInGroup.idCustomer
Group by
CustomersGroups.idCustomerGroup, Customers.type
is there a way to show them in a single line , (and show the name of the group?)
This is a "pivot" query. Some databases directly support pivot syntax. In all, you can use conditional aggregation.
Perhaps more importantly, you should learn to use table aliases. These make queries easier to write and to read:
select cg.idCustomerGroup,
sum(case when c.type = 'Type1' then 1 else 0 end) as num_type1,
sum(case when c.type = 'Type2' then 1 else 0 end) as num_type2,
sum(case when c.type = 'Type3' then 1 else 0 end) as num_type3
from CustomersGroups cg inner Join
CustomersInGroup cig
on cg.idCustomerGroup = cig.idCustomerGroup inner Join
Customers c
on c.idCustomer = cig.idCustomer
Group by cg.idCustomerGroup;
I have a sql statement with many inner join tables, as you can see below I have many conditional SUM statements , these sums are giving me wrong (very large) numbers as the inner join is repeating the same values in my source select pool. I was wondering id there is a way to limit these sum conditions lets say to EMPLIDs. The code is :
SELECT
A.EMPL_CTG,
B.DESCR AS PrName,
SUM(A.CURRENT_COMPRATE) AS SALARY_COST_BUDGET,
SUM(A.BUDGET_AMT) AS BUDGET_AMT,
SUM(A.BUDGET_AMT)*100/SUM(A.CURRENT_COMPRATE) AS MERIT_GOAL,
SUM(C.FACTOR_XSALARY) AS X_Programp,
SUM(A.FACTOR_XSALARY) AS X_Program,
COUNT(A.EMPLID) AS EMPL_CNT,
COUNT(D.EMPLID),
SUM(CASE WHEN A.PROMOTION_SECTION = 'Y' THEN 1 ELSE 0 END) AS PRMCNT,
SUM(CASE WHEN A.EXCEPT_IND = 'Y' THEN 1 ELSE 0 END) AS EXPCNT,
(SUM(CASE WHEN A.PROMOTION_SECTION = 'Y' THEN 1 ELSE 0 END)+SUM(CASE WHEN A.EXCEPT_IND = 'Y' THEN 1 ELSE 0 END))*100/(COUNT(A.EMPLID)) AS PEpercent
FROM
EMP_DTL A INNER JOIN EMPL_CTG_L1 B ON A.EMPL_CTG = B.EMPL_CTG
INNER JOIN
ECM_PRYR_VW C ON A.EMPLID=C.EMPLID
INNER JOIN ECM_INELIG D on D.EMPL_CTG=A.EMPL_CTG and D.YEAR=YEAR(getdate())
WHERE
A.YEAR=YEAR(getdate())
AND B.EFF_STATUS='A'
GROUP BY
A.EMPL_CTG,
B.DESCR
ORDER BY B.DESCR
I already tried moving D.YEAR=YEAR(getdate()) to the where clause. Any help would be greatly appereciated
The probable reason of your very large numbers is probably due to the result of Cartesian product of joining A -> B, A -> C and A -> D where tables C and D appear to have multiple records. So, just example... if A has 10 records, and C has 10 for each of the A records, you now have 10 * 10 records... Finally, join that to D table with 10 records, you now have 10 * 10 * 10 for each "A", thus your bloated answers.
Now, how to resolve. I have taken your "C" and "D" tables and "Pre-Aggregated" those counts based on the join column basis. This way, they will each have only 1 record with the total already computed at that level, joined back to A table and you lose your Cartesian issue.
Now, for table B, it appears that is a lookup table only and would only be a single record result anyhow.

I am using TOAD for Oracle. While i implement some sql queries i encountered these problem:
I am using a few tables that each of them has approx. 10M rows for a select query. 2 tables have over 70M rows data.
Let's say i have;
a TRANSACTION table (prim. key: SQ_TRANSACTION_ID)
a TRANSACTION_DETAIL table (foreign keys: RF_TRANSACTION_ID,
RF_PRODUCT_ID)
a PRODUCT table (prim. key: SQ_PRODUCT_ID)
My select query is like;
SELECT TR.TRANSACTION_ID,
SUM(CASE WHEN PR.CD_PRODCUT_TYPE = 'A'
THEN TRD.CS_INVOICE_PRICE ELSE 0 END) A_PRODUCT_TOTAL,
SUM(CASE WHEN PR.CD_PRODCUT_TYPE <> 'A'
THEN TRD.CS_INVOICE_PRICE ELSE 0 END) B_PRODUCT_TOTAL
FROM TRANSACTION TR,
TRANSACTION_DETAIL TRD,
PRODUCT PR
WHERE TR.SQ_TRANSACTION_ID = TRD.RF_TRANSACTION_ID
AND TRD.RF_PRODUCT_ID = PR.SQ_PRODUCT_ID
GROUP BY TR.TRANSACTION_ID,
CASE WHEN PR.CD_PRODCUT_TYPE = 'A' THEN TRD.CS_INVOICE_PRICE ELSE 0 END,
CASE WHEN PR.CD_PRODCUT_TYPE <> 'A' THEN TRD.CS_INVOICE_PRICE ELSE 0 END
Is there a way to split this query into two or more parts with referenced each other by using their foreign/primary keys? I mean like splitting into two parts that first part fetches A_PRODUCT_TOTAL and second part fetches B_PRODUCT_TOTAL. Each part's transaction id should match at the result data.
A direct translation of your query would be:
SELECT TR.TRANSACTION_ID, SUM(TRD.CS_INVOICE_PRICE) A_PRODUCT_TOTAL
FROM TRANSACTION TR join
TRANSACTION_DETAIL TRD
on TR.SQ_TRANSACTION_ID = TRD.RF_TRANSACTION_ID join
PRODUCT PR
on TRD.RF_PRODUCT_ID = PR.SQ_PRODUCT_ID
WHERE PR.CD_PRODCUT_TYPE = 'A'
GROUP BY TR.TRANSACTION_ID,
CASE WHEN PR.CD_PRODCUT_TYPE = 'A' THEN TRD.CS_INVOICE_PRICE ELSE 0 END
However, I suspect that you don't want the second clause in the group by, because each transaction would be split into reows where the invoice price is the same:
SELECT TR.TRANSACTION_ID, SUM(TRD.CS_INVOICE_PRICE) A_PRODUCT_TOTAL
FROM TRANSACTION TR join
TRANSACTION_DETAIL TRD
on TR.SQ_TRANSACTION_ID = TRD.RF_TRANSACTION_ID join
PRODUCT PR
on TRD.RF_PRODUCT_ID = PR.SQ_PRODUCT_ID
WHERE PR.CD_PRODCUT_TYPE = 'A'
GROUP BY TR.TRANSACTION_ID;
The query for 'B' would be similar.
