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

I want write hive query such that it I can see count of null values of each column
You can use this SQL - this will give you total count, null and not null count.
SELECT
count(*) total_cnt,
sum(case when data_col is null then 1 else 0 end) null_cnt,
sum(case when data_col is null then 0 else 1 end) nonnull_cnt
From mytable
I have a table contain records as per below image. I want to do a count for each status and am able to do that by selecting each type of status. Which I will needs to exec 4 query to get the result. I would like to know how can I achieve that by using single query statement? Any advices or suggestion is welcome and highly appreciated. Thanks in advance.
WITH CTE(NO,STATUS)AS
(
SELECT 1,'OPEN' UNION ALL
SELECT 2,'OPEN'UNION ALL
SELECT 3,'BILLED'UNION ALL
SELECT 4,'CANCELLED'UNION ALL
SELECT 5,'BILLING'UNION ALL
SELECT 6,'BILLED'UNION ALL
SELECT 7,'CANCELLED'UNION ALL
SELECT 8,'BILLING'UNION ALL
SELECT 9,'CONFIRM'UNION ALL
SELECT 10,'IN PROGRESS'UNION ALL
SELECT 11,'OPEN'UNION ALL
SELECT 12,'CONFIRM'
)
SELECT
SUM(CASE WHEN C.STATUS='BILLED'THEN 1 ELSE 0 END)AS BILLED,
SUM(CASE WHEN C.STATUS='BILLING'THEN 1 ELSE 0 END)AS BILLING,
SUM(CASE WHEN C.STATUS='CANCELLED'THEN 1 ELSE 0 END)AS CANCELLED,
SUM(CASE WHEN C.STATUS NOT IN ('CANCELLED','BILLING','BILLED')THEN 1 ELSE 0 END)AS UNBILL
FROM CTE AS C
CTE is an example you have provided. Please replace reference to it with reference to your table
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
I am including a SQLFiddle to show as an example of where I am currently at. In the example image you can see that simply grouping you get up to two lines per user depending on their status and how many of those statuses they have.
http://sqlfiddle.com/#!3/9aa649/2
The way I want it to come out is to look like the image below. Having a single line per user with two totaling columns one for Fail Total and one for Pass Total. I have been able to come close but since BOB only has Fails and not Passes this query leaves BOB out of the results. which I want to show BOB as well with his 6 Fail and 0 Pass
select a.PersonID,a.Name,a.Totals as FailTotal,b.Totals as PassTotals from (
select PersonID,Name,Status, COUNT(*) as Totals from UserReport
where Status = 'Fail'
group by PersonID,Name,Status) a
join
(
select PersonID,Name,Status, COUNT(*) as Totals from UserReport
where Status = 'Pass'
group by PersonID,Name,Status) b
on a.PersonID=b.PersonID
The below picture is what I want it to look like. Here is another SQL Fiddle that shows the above query in action
http://sqlfiddle.com/#!3/9aa649/13
Use conditional aggregation if the number of values for status column is fixed.
Fiddle
select PersonID,Name,
sum(case when "status" = 'Fail' then 1 else 0 end) as failedtotal,
sum(case when "status" = 'Pass' then 1 else 0 end) as passedtotals
from UserReport
group by PersonID,Name
Use conditional aggregation:
select PersonID, Name,
sum(case when Status = 'Fail' then 1 else 0 end) as FailedTotal,
sum(case when Status = 'Pass' then 1 else 0 end) as PassedTotal
from UserReport
group by PersonID, Name;
With conditional aggregation:
select PersonID,
Name,
sum(case when Status = 'Fail' then 1 end) as Failed,
sum(case when Status = 'Passed' then 1 end) as Passed
from UserReport
group by PersonID, Name
I am having trouble formulating a query to get the desired output.
This query involves one table and two columns.
First column bld_stat has 4 different values Private, public, Public-Abandoned, Private-Abandoned the other column bld_type, single_flr, multi_flr, trailer, Whs.
I need to get results that look like this:
So far I can get the first two columns but after that I have not been able to logically get a query to work
SELECT bld_stat, COUNT(grade) AS single_flr
FROM (SELECT bld_stat,bld_type
FROM bld_inventory WHERE bld_type = 'single_flr') AS grade
GROUP BY bld_stat,bld_type,grade
The term you are going for is pivoting. I think this should work...no need for the subquery, and I've changed your group by to only bld_stat
SELECT bld_stat,
sum(case when bld_type = 'singl_flr' then 1 else 0 end) AS single_flr,
sum(case when bld_type = 'multi_flr' then 1 else 0 end) AS multi_flr,
sum(case when bld_type = 'trailer' then 1 else 0 end) AS trailer,
sum(case when bld_type = 'whs' then 1 else 0 end) AS WHS
FROM bld_inventory
GROUP BY bld_stat
