Need help in building MYSQL query to count two content from single row/table

Question

I\'m trying to get count of two set of data which is listed under same table name, with specific date range.

Table \'Event\'

u_id event  Create
123  F_lo         


        

Answer 1

Query

SELECT t.`Create`, 
SUM(CASE WHEN t.`F_log` > 0 THEN 1 ELSE 0 END) as `F_log`,
SUM(CASE WHEN t.`C_log` > 0 THEN 1 ELSE 0 END) as `C_log` FROM(
    select `u_id`, `Create`,
    SUM(CASE WHEN `event` = 'F_log' THEN 1 ELSE 0 END) AS `F_log`,
    SUM(CASE WHEN `event` = 'C_log' THEN 1 ELSE 0 END) AS `C_log`
    FROM `Event`
    GROUP BY `u_id`, `Create`
)t
GROUP BY t.`Create`;

Answer 2

select to_char(cast(created as date),'YYYY-MM-DD') as Report_date, count(distinct(case when event_type in ('Flash C Log') then user_id else 0 end)) as Flash_Log, count(distinct(case when (event_type = 'Client C Log') then user_id else 0 end)) as Client_Log from events e where created between '25-SEP-16' and '27-SEP-16' group by to_char(cast(created as date),'YYYY-MM-DD') order by to_char(cast(created as date),'YYYY-MM-DD');

Answer 3

The COUNTs has to be done in separate subqueries. This should work.

SELECT DISTINCT E.created,F.flash,C.client
FROM events E
LEFT JOIN (
    SELECT created,COUNT(DISTINCT user_id) as flash
    FROM events
    WHERE event_type LIKE 'Flash C log'
    GROUP BY created
) F
ON F.created = E.created
LEFT JOIN (
    SELECT Created,COUNT(DISTINCT user_id) as client
    FROM events
    WHERE event_type LIKE 'Client C log'
    GROUP BY created
) C
ON C.created = E.created
WHERE E.created BETWEEN '2016-09-25' AND '2016-09-27'

Fiddle with results

EDIT: As of your comments, I have made a question that adds a column of the distinct combined userids with clients and flash logs for each date. I added a little data to that fiddle to test.

SELECT DISTINCT E.created,F.flash,C.client,FC.combined
FROM events E
LEFT JOIN (
    SELECT created,COUNT(DISTINCT user_id) as flash
    FROM events
    WHERE event_type LIKE 'Flash C log'
    GROUP BY created
) F
ON F.created = E.created
LEFT JOIN (
    SELECT Created,COUNT(DISTINCT user_id) as client
    FROM events
    WHERE event_type LIKE 'Client C log'
    GROUP BY created
) C
ON C.created = E.created
LEFT JOIN (
    SELECT Created,COUNT(DISTINCT user_id) as combined
    FROM events
    WHERE event_type LIKE 'Client C log' OR event_type LIKE 'Flash C log'
    GROUP BY created
) FC
ON FC.created = E.created
WHERE E.created BETWEEN '2016-09-25' AND '2016-09-27'
