I need to have a SQL query to calculate the percentage of courses completed by location which are different SQL tables.
Courses table has a Status = 'C' (Completed status).
select Locations.Name, ( ??? ) as PercentCompleted
from Locations inner join Candidates ON Locations.Id = Candidates.SpecifiedLocation
inner join Courses on Candidates.Id = Courses.CandidateId
Group By Locations.Name
I want the results to be:
Location PercentCompleted
Loc1 10
Loc2 50
Loc3 75
where 10, 50 and 75 are percentages of courses completed per location.
Can this be achieved with a single SQL query?
If I understand correctly, I think you can do:
select l.Name,
avg(case when co.status = 'C' then 100.0 else 0 end) as PercentCompleted
from Locations l inner join
Candidates c
on l.Id = c.SpecifiedLocation inner join
Courses co
on c.Id = co.CandidateId
group by l.name;
try like below
select Locations.Name, (sum(case when Status = 'C' then 1 else 0 end)/(select count(*)
from Candidates c where c.SpecifiedLocation=Locations.Id))*100
as PercentCompleted
from Locations inner join Candidates ON Locations.Id = Candidates.SpecifiedLocation
inner join Courses on Candidates.Id = Courses.CandidateId
Group By Locations.Name

i have 2 SQL query, i want to make both in one SQL query and get all the elements from each query only in one row.
I want to have 6 columns for the result("kunde", "GesamtdateiGrosse", "anzahlObjGesamt", "GesamtdateiGrossefertig", "anzahlObjFertig" "RestGross") and 2 lines. RestGross would then be the difference between GesamtdateiGrosse and GesamtdateiGrossefertig
SELECT
kunde.nummer AS kunde,
SUM(datei.groesse) as "GesamtdateiGrosse",
COUNT (DISTINCT objekt.id) as anzahlObjGesamt
FROM datei
INNER JOIN objekt ON datei.id_objekt = objekt.id
INNER JOIN auftrag ON objekt.id_auftrag = auftrag.id
INNER JOIN kunde ON auftrag.id_kunde = kunde.id
WHERE kunde.nummer = 777
GROUP BY kunde.nummer
UNION
SELECT
kunde.nummer AS kunde,
SUM(datei.groesse) as "GesamtdateiGrossefertig",
COUNT (DISTINCT objekt.id) as anzahlObjFertig
FROM datei
INNER JOIN objekt ON datei.id_objekt = objekt.id
INNER JOIN auftrag ON objekt.id_auftrag = auftrag.id
INNER JOIN status ON objekt.id_restorestatus = status.id
INNER JOIN kunde ON auftrag.id_kunde = kunde.id
WHERE status.name = 'fertig' AND kunde.nummer = 777
GROUP BY kunde.nummer
I expect the output 3 rown 3 column (Kunde, "GesamtdateiGrosse",anzahlObjGesamt)
This should get you close to what you want. The idea is to add another join in the first to bring in the status table, and the do conditional aggregation.
This requires that there is a 1:1 relationship between objekt and status (meaning that, for a given record in objekt, there is always one and only one record in status that satisfies condition objekt.id_restorestatus = status.id).
Consider:
SELECT
kunde.nummer AS kunde,
SUM(datei.groesse) as "GesamtdateiGrosse",
COUNT(DISTINCT objekt.id) as anzahlObjGesamt,
SUM(CASE WHEN status.name = 'fertig' THEN datei.groesse ELSE 0 END) as "GesamtdateiGrossefertig",
COUNT (DISTINCT (CASE WHEN status.name = 'fertig' THEN objekt.id END)) as anzahlObjFertig
FROM datei
INNER JOIN objekt ON datei.id_objekt = objekt.id
INNER JOIN auftrag ON objekt.id_auftrag = auftrag.id
INNER JOIN kunde ON auftrag.id_kunde = kunde.id
INNER JOIN status ON objekt.id_restorestatus = status.id
WHERE kunde.nummer = 777
GROUP BY kunde.nummer
I have a sql query that creates a label in a cab file for a shopping company. I want to include the amount of packages in an order, some have multiple.
Each returns line in my select query has an I’d and contains a package but I need to count them.
So I have:
Name Email Weight Price ID
Joe B J#.com 10 12.5. 1
Joe B J#.com 10 12.5. 1
Joe C JC#.com 10 14.5. 2
How can I count the ID’s to return a column called pieces and in this example it would be 2 for ID 1 and 1 for ID 2
Thanks
James

You can use GROUP BY with COUNT like this:
SELECT ID, COUNT(*) as count FROM tbl GROUP BY ID
What I understood from your question is that, you are looking for output like
Name Email Weight Price ID Pieces
Joe B J#.com 10 12.5. 1 2
Joe B J#.com 10 12.5. 1 2
Joe C JC#.com 10 14.5. 2 1
Using following query you should get the desired output in most of the DBMS.
SELECT NAME,
EMAIL,
WEIGHT,
PRICE,
ID,
(SELECT Count(*)
FROM <YOUR_TABLE_NAME>
WHERE ID= OU.ID) AS Pieces
FROM <YOUR_TABLE_NAME> OU
Similar Query for MS SQL Server can be
SELECT NAME, EMAIL,WEIGHT , Price, ID,CT.Pieces
FROM <YOUR_TABLE_NAME> OU
CROSS APPLY
(
SELECT COUNT(*) AS Pieces FROM <YOUR_TABLE_NAME> IU WHERE OU.ID=IU.ID
)CT
given these relationships, how could you query the following:
The tourists (name and email) that booked at least a pension whose rating is greater than 9, but didn't book any 3 star hotel with a rating less than 9.
Is the following correct?
SELECT Tourists.name, Tourists.email
FROM Tourists
WHERE EXISTS (
SELECT id FROM Bookings
INNER JOIN Tourists ON Bookings.touristId=Tourists.id
INNER JOIN AccomodationEstablishments ON Bookings.accEstId=AccomodationEstablishments.id
INNER JOIN AccomodationTypes ON AccomodationEstablishments.accType=AccomodationTypes.id
WHERE AccomodationTypes.name = 'Pension' AND
AccomodationEstablishments.rating > 9
) AND NOT EXISTS (
SELECT id FROM Bookings
INNER JOIN Tourists ON Bookings.touristId=Tourists.id
INNER JOIN AccomodationEstablishments ON Bookings.accEstId=AccomodationEstablishments.id
INNER JOIN AccomodationTypes ON AccomodationEstablishments.accType=AccomodationTypes.id
WHERE AccomodationTypes.name = 'Hotel' AND
AccomodationEstablishments.noOfStars = 3 AND
AccomodationEstablishments.rating < 9
)
I would do this using aggregation and having:
SELECT t.name, t.email
FROM Bookings b INNER JOIN
Tourists t
ON b.touristId = t.id INNER JOIN
AccomodationEstablishments ae
ON b.accEstId = ae.id INNER JOIN
AccomodationTypes a
ON ae.accType = a.id
GROUP BY t.name, t.email
HAVING SUM(CASE WHEN a.name = 'Pension' AND ae.rating > 9 THEN 1 ELSE 0 END) > 0 AND
SUM(a.name = 'Hotel' AND ae.noOfStars = 3 AND ae.rating < 9 THEN 1 ELSE 0 END)= 0;
Your method also works, but you probably need t.id in the subqueries.
I have 2 tables
Company & products
I need to get 2 counts. One is the total count of products and the secondly count of products for sale_flg=1
This SQL does not seem to work..Tried several other ways..not able to get the expected results
SELECT A.COMPANY_NAME, COUNT(B.PRODUCT_ID) AS TOTAL_COUNT_OF_PRODUCTS,
(CASE WHEN B.SALEFLG =1 THEN 1 END) AS COUNT_OF_SALES
FROM COMPANY A LEFT JOIN
PRODUCT B
ON B.COMPANY_ID = A.COMPANY_ID
GROUP BY A.COMPANY_NAME
I think you just need a sum for the case:
SELECT C.COMPANY_NAME, COUNT(P.PRODUCT_ID) AS TOTAL_COUNT_OF_PRODUCTS,
SUM(CASE WHEN P.SALEFLG = 1 THEN 1 ELSE 0 END) AS COUNT_OF_SALES
FROM COMPANY C LEFT JOIN
PRODUCT P
ON P.COMPANY_ID = C.COMPANY_ID
GROUP BY C.COMPANY_NAME ;
If you have B.SALEFLG = 1 or 0 for you may try
Sum(B.SALEFLG) AS COUNT_OF_SALES
Or use UNION
If you use count then in else you should consider null because null is not consider in count aggregation and if you have B.SALEFLG =1 or 0 then use sum aggregation.
You can try below code:
SELECT A.COMPANY_NAME, COUNT(B.PRODUCT_ID) AS TOTAL_COUNT_OF_PRODUCTS,
count(CASE WHEN B.SALEFLG =1 THEN 1 else null END) AS COUNT_OF_SALES
FROM COMPANY A LEFT JOIN
PRODUCT B
ON B.COMPANY_ID = A.COMPANY_ID
GROUP BY A.COMPANY_NAME
OR try this:
SELECT A.COMPANY_NAME, COUNT(B.PRODUCT_ID) AS TOTAL_COUNT_OF_PRODUCTS,
sum(B.SALEFLG) AS COUNT_OF_SALES
FROM COMPANY A LEFT JOIN
PRODUCT B
ON B.COMPANY_ID = A.COMPANY_ID
GROUP BY A.COMPANY_NAME
This SQL server query is working.
Company Table and Product Table
Company Table CompanyID is join with Product table and sales_flg add in product table .
sales_flg = 1 record display in CntSalesflg
select Comp.CompID as CompID, COUNT(Pro.ProductID) as CntProdustID,
SUM(CASE WHEN Pro.SalesflagID = 1 THEN 1 ELSE 0 END) as CntSalesflg
from Product as Pro
inner join Company as Comp on Pro.CompID = Comp.CompID
GROUP by Comp.CompID
I have 3 queries that I want to combine. 1 query is for total sales, 1 is for canceled orders, and 1 is for orders that don't include specific product types. Just need the total sales $$ to output in a table format as they are now. The only thing that changes between the 3 is the where statement. Thanks!
Edit: I realize I said "Just need the total sales $$" ... what I meant was I just need the sales $$ for each query in one table. So $x, $y, $z ... x is the total sales, y is the sales dollars that got cancelled, and z is the sales dollars for the specific items.
SELECT Sum((Items.Total+Items.Shipping)*OrderDetails.Quantity) AS Total
FROM Promo INNER JOIN (Orders INNER JOIN (Items INNER JOIN OrderDetails ON Items.ItemCode = OrderDetails.ItemCode) ON Orders.OrderNumber = OrderDetails.OrderNumber) ON Promo.Promo = Orders.Promo
WHERE ((Promo.OfferType)='Sale') AND ((Items.Date) Between '6/1/2010' And '12/31/2011');
SELECT Sum((Items.Total+Items.Shipping)*OrderDetails.Quantity) AS Canceled
FROM Promo INNER JOIN (Orders INNER JOIN (Items INNER JOIN OrderDetails ON Items.ItemCode = OrderDetails.ItemCode) ON Orders.OrderNumber = OrderDetails.OrderNumber) ON Promo.Promo = Orders.Promo
WHERE (((Promo.OfferType)='Sale') AND ((Items.Date) Between '6/1/2010' And '12/31/2011') AND ((Items.Status)="Canceled"));
SELECT Sum((Items.Total+Items.Shipping)*OrderDetails.Quantity) AS BadItems
FROM Promo INNER JOIN (Orders INNER JOIN (Items INNER JOIN OrderDetails ON Items.ItemCode = OrderDetails.ItemCode) ON Orders.OrderNumber = OrderDetails.OrderNumber) ON Promo.Promo = Orders.Promo
WHERE (((Promo.OfferType)='Sale') AND ((Items.Date) Between '6/1/2010' And '12/31/2011') AND ((Items.ProductType)<>2) AND ((Items.ProductType)<>6));
Thanks!
If you want the results on 1 row:
SELECT Total, Canceled, BadItems
FROM Query1, Query2, Query3
And if you want the results in 1 column, use a UNION:
Query1
UNION
Query2
UNION
Query3
Updated to reflect question clarification:
SELECT Sum(CASE WHEN Items.Status <> 'Canceled' AND Items.ProductType = 4 THEN (Items.Total+Items.Shipping)*OrderDetails.Quantity ELSE 0 END) AS Total ,
Sum(CASE WHEN Items.Status = 'Canceled' AND Items.ProductType = 4 THEN (Items.Total+Items.Shipping)*OrderDetails.Quantity ELSE 0 END) AS Canceled,
Sum(CASE WHEN Items.ProductType <> 4 THEN (Items.Total+Items.Shipping)*OrderDetails.Quantity ELSE 0 END) AS BadItems,
FROM Promo INNER JOIN (Orders INNER JOIN (Items INNER JOIN OrderDetails ON Items.ItemCode = OrderDetails.ItemCode) ON Orders.OrderNumber = OrderDetails.OrderNumber) ON Promo.Promo = Orders.Promo
WHERE ((Promo.OfferType)='Sale') AND ((Items.Date) Between '9/1/2010' And '12/31/2010');
try to use a procedure which will accept three values as input which will suite your were statements and it will give results in one table as want. if you are stuck let me know , i will help.
