I have a product table and every product might be delivered, idle, shipping, preparing.
I want to show a list with the counts of products for each state, and I can see how to query for that here:
How to get multiple counts with one SQL query?
However, what does this query return, and how do I assign the return value to lets say, 4 integers, called deliveredCount, idleCount, shippingCount, preparingCount?
PS: For the record, I am using SQLite with OrmLite in Android with JAVA
EDIT: In this SO question people explain what Query to do when you want to get multiple counts, but they don't tell us what does that query return and in what format. For example:
SELECT a.distributor_id,
(SELECT COUNT(*) FROM myTable WHERE level='personal' and distributor_id = a.distributor_id) as PersonalCount,
(SELECT COUNT(*) FROM myTable WHERE level='exec' and distributor_id = a.distributor_id) as ExecCount,
(SELECT COUNT(*) FROM myTable WHERE distributor_id = a.distributor_id) as TotalCount
FROM myTable a ;
What is the return type of this and what is the format?
PS2: Someone was really quick to downvote my question because it lacked sufficient information. Then I edited it, but the downvote still remains :(
Hard to say for sure but sounds like you need to use a version of the top answer in the link you have provided.
Something like;
SELECT ProductID,
COUNT(*) AS Total,
SUM(CASE WHEN pStatus = 'delivered' THEN 1 ELSE 0 END) DeliveredCount,
SUM(CASE WHEN pStatus = 'idle' THEN 1 ELSE 0 END) IdleCount,
SUM(CASE WHEN pStatus = 'shipping' THEN 1 ELSE 0 END) ShippingCount,
SUM(CASE WHEN pStatus = 'preparing' THEN 1 ELSE 0 END) PreparingCount
FROM ProductTable
GROUP BY ProductID
This will return something like;
ProductID | DeliveredCount | IdleCount | ...
1 | 250 | 3250 | ...
You might want to try this.
SELECT
SUM(CASE WHEN Prod = 'delivered' THEN 1 ELSE 0 END) as deliveredCount,
SUM(CASE WHEN Prod = 'idle' THEN 1 ELSE 0 END) as idleCount,
SUM(CASE WHEN Prod = 'shipping' THEN 1 ELSE 0 END) as shippingCount,
SUM(CASE WHEN Prod = 'preparing' THEN 1 ELSE 0 END) as preparingCount
FROM Product
select
concat(state, "Count"),
count(*)
from product
group by state
Which would return 4 rows (assuming four unique values of state):
fooCount | 15
etc

Please help on this. Sometimes my title maybe wrong. Actually i'm unable to explain the problem in word. See below images. Image 1 is db table structure. Image 2 is what I expect result.
I used mentioned query and got result as below image. Also I need to remove 'NULL's and same URGENT_LEVEL values in one row. How i do that? Using ms-sql server.
select TRACKING_NUMBER,URGENT_LEVEL,
case when FROM_KM = '0' then Charge end as 'Under1km' ,
case when FROM_KM='1' then Charge end as '1-100KM'
from my_table
where TRACKING_NUMBER = 'TEST001'
After query
You can use conditional aggregation:
select tracking_number, urgent_level,
sum(case when to_km - from_km <= 1 then charge else 0 end) as charge_under_1,
sum(case when to_km - from_km > 1 and to_km - from_km <= 100 then charge else 0 end) as charge_1_100
from t
group by tracking_number, urgent_level;
I don't know which database you are using, but you need to use group by clause, and something similar to case expression (in oracle) as below :
select TRACKING_NUMBER
, URGENT_LEVEL
, max(case when FROM_KM = 0 and TO_KM = 1 then CHARGE end) as "UNDER 1KM"
, max(case when FROM_KM = 1 and TO_KM = 100 then CHARGE end) as "1-100KM"
from your_table
where TRACKING_NUMBER = 'TEST001'
group by TRACKING_NUMBER, URGENT_LEVEL
order by "UNDER 1KM"
;
I want to group by account number, but I am running into problems if I get multiple RATE_CD's for an account - I get a NONCOMPLIANT_CNT of 2, but I want it to be only 1 per account even if there is more than 1 RATE_CD.
Below is the SQL I'm playing around with, any ideas on how I can return the NONCOMPLIANT_CNT per account, and not roll up the count if there is more than 1 RATE_CD?
SELECT ID
,ACCOUNT_NBR SUM(CASE
WHEN GROUP_CD = 'RED'
AND TYPE_CD IN ('CHK')
THEN 1
ELSE 0
END) AS 'COMPLIANT_CNT'
,SUM(CASE
WHEN GROUP_CD = 'RED'
AND TYPE_CD IN (
'CN'
,'RN'
)
AND RATE_CD <> 'BLK'
THEN 1
ELSE 0
END) AS 'NONCOMPLIANT_CNT'
,SUM(CASE
WHEN GROUP_CD = 'RED'
AND TYPE_CD IN (
'CN'
,'RN'
,'CHK'
)
THEN 1
ELSE 0
END) AS 'TOTAL_CNT'
FROM DETAIL
LEFT OUTER JOIN RATE_LOOKUP ACCOUNT_NBR = ACCOUNT_NBR
GROUP BY ID
,ACCOUNT_NBR
,RATE_CD
If you only want 1 instead of how many actual, change your SUM() to MAX(). So if they have 5 entries, it would still show as at least 1, otherwise will be 0 for the given column aggregate.
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

Table structures:
Solution_Votes:
ID int
SolutionID string
Vote int
Solution:
ID int
Solution
VotesUp
VotesDown
Code:
SELECT
*,
(SELECT SUM(CASE WHEN voteUp = 1 THEN 1 ELSE 0 END)
FROM Solutions_Votes) AS VoteCountUp,
(SELECT SUM(CASE WHEN voteDown = 0 THEN 1 ELSE 0 END)
FROM Solutions_Votes) AS VoteCountDown
FROM
Solution
When I run this query it gives me the count on each row for voteUpCount and voteDownCount. I need the count to be based on the solution ID so that each solution has its count of up votes and down votes. If anybody can help it would be appreciated. Thanks in advance!
Just use conditional aggregation. In your case this is simple:
select sv.solutionid,
sum(case when sv.voteUp = 1 then 1 else 0 end) as VoteCountUp,
sum(case when sv.voteDown = 0 then 1 else 0 end) as VoteCountDown
from solutions_votes sv
group by sv.solutionid;
You only need the solutions table if some solutions have no votes and you want to include them.
EDIT:
You would include solutions in various way. Here is one:
select s.*, ss.VoteCountUp, ss.VoteCountDown
from solutions s left join
(select sv.solutionid,
sum(case when sv.voteUp = 1 then 1 else 0 end) as VoteCountUp,
sum(case when sv.voteDown = 0 then 1 else 0 end) as VoteCountDown
from solutions_votes sv
group by sv.solutionid
) ss
on s.solutionid = ss.solutionid;
I'm trying to write a query that returns the following columns:
owner_id,
number_of_concluded_bookings,
number_of_declined_bookings,
number_of_inquiries
However, the problem is that my WHERE clause messes up the query because I am querying the same table. Here is the code:
SELECT owner_id,
Count(*) AS number_of_cancelled_bookings
FROM bookings
WHERE state IN ('cancelled')
GROUP BY owner_id
ORDER BY 1;
It's easy to retrieve the columns individually, but I want all of them. Say I wanted number_of_concluded_bookings as well, that would mean I'd have to alter the WHERE clause ...
Help is greatly appreciated!
Consider conditional aggregations:
SELECT owner_id,
SUM(CASE WHEN state='concluded' THEN 1 ELSE 0 END) AS number_of_concluded_bookings,
SUM(CASE WHEN state='cancelled' THEN 1 ELSE 0 END) AS number_of_cancelled_bookings,
SUM(CASE WHEN state='declined' THEN 1 ELSE 0 END) AS number_of_declined_bookings,
SUM(CASE WHEN state='inquiries' THEN 1 ELSE 0 END) AS number_of_inquiries
FROM bookings
GROUP BY owner_id
