Question

I have a select query in MySQL shown below:
This query executes and produces results in the form of a table

Current | Past1  | Past2  | Past 3  |  Past4
   200     600      800      000         88
-----------------------------------------------

I would like to transpose these results to get information in the form: Therefore I would like the reults to be (transposed)

Current    200
Past1      600
Past2      800
Past3      000
Past4       88

Can this be done using a SQL statement in oracle or do I need a PL SQL procedure for this. If a PL SQL can you provide some sample reference to it.

select
sum(case
    when CPT_ORIGINATED > SUBDATE(DATE(NOW()),30) THEN 1 else 0
    end) as Current,
sum(case
    when CPT_ORIGINATED > SUBDATE(DATE(NOW()),60) AND CPT_ORIGINATED < SUBDATE(DATE(NOW()),30) THEN 1 else 0
    end) as Past1,
sum(case
    when CPT_ORIGINATED > SUBDATE(DATE(NOW()),90) AND CPT_ORIGINATED < SUBDATE(DATE(NOW()),60) THEN 1 else 0
    end) as Past2,
sum(case
    when CPT_ORIGINATED > SUBDATE(DATE(NOW()),120) AND CPT_ORIGINATED < SUBDATE(DATE(NOW()),90) THEN 1 else 0
    end) as Past3,
sum(case
    when CPT_ORIGINATED > SUBDATE(DATE(NOW()),150) AND CPT_ORIGINATED < SUBDATE(DATE(NOW()),120) THEN 1 else 0
    end) as Past4
from `cpt-prod`
where CPT_STATE <> 'Closed'

Answer 1

How about something like this:

select 'Current' As TimePeriod,
sum(case when CPT_ORIGINATED > SUBDATE(DATE(NOW()),30) THEN 1 else 0
    end) as CountOfThings,
from `cpt-prod`
where CPT_STATE <> 'Closed'
UNION ALL
SELECT 'Past1' AS TimePeriod,
sum(case when CPT_ORIGINATED > SUBDATE(DATE(NOW()),60) AND CPT_ORIGINATED < SUBDATE(DATE(NOW()),30) THEN 1 else     0
    end) as CountOfThings,
from `cpt-prod`
where CPT_STATE <> 'Closed'

and so on for each row?
