Question

So.. here is the thing.. Im trying to get a report based on this table on Mysql.
Table have these columns
statusvalue submitdate employeeNumber
2 2016-11-17 17:49:05 2
1 2016-11-17 17:49:11 4
3 2016-11-17 17:49:16 4
4 2016-11-17 17:50:58 2
5 2016-11-17 17:51:07 5
Status 0 = Pending
1= Started
2=inprogress
3= cancelled
4= terminated
5=unknown
now i need to select data as below
date day pending started inprogress cancelled terminated total
2017-04-17 Monday 0 1 4 0 1 6
2017-04-16 Sunday 0 1 4 0 1 6
so far i can get the date and the day
select date(submitdate) as subdate, case weekday(date(submitdate))
WHEN 0 then 'PENDING'
WHEN 1 then 'STARTED'
WHEN 2 then 'INPROGRESS'
WHEN 3 then 'CANCELLED'
WHEN 4 then 'TERMINATED'
WHEN 5 then 'UNKNOWN' END as submitdate
from tb_status t1 where employeenumber=15 group by subdate order by subdate ;
however not quite sure how to do a count based on status.. any help would be greatly appreciated.

Answer 1

You just need a basic pivot query here. Aggregate over the submission date, and then tally the various types of status as you go along.
SELECT
DATE(submitdate) AS subdate,
WEEKDAY(submitdate) AS day,
SUM(CASE WHEN WEEKDAY(DATE(submitdate)) = 0 THEN 1 END) AS PENDING,
SUM(CASE WHEN WEEKDAY(DATE(submitdate)) = 1 THEN 1 END) AS STARTED,
SUM(CASE WHEN WEEKDAY(DATE(submitdate)) = 2 THEN 1 END) AS INPROGRESS,
SUM(CASE WHEN WEEKDAY(DATE(submitdate)) = 3 THEN 1 END) AS CANCELLED,
SUM(CASE WHEN WEEKDAY(DATE(submitdate)) = 4 THEN 1 END) AS TERMINATED,
SUM(CASE WHEN WEEKDAY(DATE(submitdate)) = 5 THEN 1 END) AS UNKNOWN
FROM tb_sattus t1
WHERE employeenumber = 15
GROUP BY DATE(submitdate)
ORDER BY subdate
Note that your current query is not correct, because you are selecting string literals based on the status. Instead, in my query the various status types appear as column names, with the counts you want instead being selected.

Give this a try:
SELECT
`submitDate` as `date`,
DATE_FORMAT(`submitDate`,'%a') as `day`,
SUM(if(`statusvalue` = 0,1,0)) as `pending`,
SUM(if(`statusvalue` = 1,1,0)) as `started`,
SUM(if(`statusvalue` = 2,1,0)) as `inprogress`,
SUM(if(`statusvalue` = 3,1,0)) as `cancelled`,
SUM(if(`statusvalue` = 4,1,0)) as `terminated`,
SUM(if(`statusvalue` = 5,1,0)) as `unknown`,
SUM(if(NOT `statusvalue` IN (0,1,2,3,4,5),1,0)) as `invalid`,
COUNT(`statusvalue`) as `total`
FROM `tbstatus`
GROUP BY `submitDate`
ORDER BY `submitDate`;
