I need to gather sums using conditional statements as well as DISTINCT
values
with a multiple GROUP BY
. The example below is a simplified version of a much much more complex query.
Because the real query is very large, I need to avoid having to drastically re-write the query.
DATA
Contracts
id advertiser_id status
1 1 1
2 2 1
3 3 2
4 1 1
A Query that's close
SELECT
COUNT( DISTINCT advertiser_id ) AS advertiser_qty,
COUNT( DISTINCT id ) AS contract_qty,
SUM( IF( status = 1, 1, 0 ) ) AS current_qty,
SUM( IF( status = 2, 1, 0 ) ) AS expired_qty,
SUM( IF( status = 3, 1, 0 ) ) AS other_qty
FROM (
SELECT * FROM `contracts`
GROUP BY advertiser_id, id
) AS temp
Currently Returns
advertiser_qty contract_qty current_qty expired_qty other_qty
3 4 3 1 0
Needs to Return
advertiser_qty contract_qty current_qty expired_qty other_qty
3 4 2 1 0
Where current_qty
is 2 which is the sum of records with status = 1
for only DISTINCT advertiser_ids
and each sum function will need the same fix.
I hope someone has a simple solution that can plug into the SUM
functions.
-Thanks!!
try this
SELECT
COUNT( DISTINCT advertiser_id ) AS advertiser_qty,
COUNT( DISTINCT id ) AS contract_qty,
(select count(distinct advertiser_id) from contracts where status =1
) AS current_qty,
SUM( IF( status = 2, 1, 0 ) ) AS expired_qty,
SUM( IF( status = 3, 1, 0 ) ) AS other_qty
FROM (
SELECT * FROM `contracts`
GROUP BY advertiser_id, id
) AS temp

EDIT:
you may look for this without subselect.
SELECT COUNT(DISTINCT advertiser_id) AS advertiser_qty,
COUNT(DISTINCT id) AS contract_qty,
COUNT(DISTINCT advertiser_id , status = 1) AS current_qty,
SUM(IF(status = 2, 1, 0)) AS expired_qty,
SUM(IF(status = 3, 1, 0)) AS other_qty
FROM (SELECT *
FROM `contracts`
GROUP BY advertiser_id, id) AS temp
