Count each day with SQL query - mysql

Question

I want to display a table with SQL query like this:
I have run my query:
select
tb_r_orderdata.finishtime as date ,
count(*)sum all,
sum(when status = 'SUCCESS' and issync = '1' then 1 else 0 end) sumpaid,
sum(when status = 'SUCCESS' and issync in ('3', '4') then 1 else 0 end) sumfail,
sum(when status = 'CLOSED' then 1 else 0 end) sumclose,
sum(when status = 'Null' then 1 else 0 end) sumunflag
from
tb_r_orderdata;
But when I execute it, the result is different than what I expected. The result is like this:
Thank you for any help

Answer 1

You are missing the GROUP BY and the CASE:
select tb_r_orderdata.finishtime as date ,
COUNT(*) as sumall,
SUM(CASE WHEN status='SUCCESS' AND issync='1' then 1 ELSE 0 END) as sumpaid,
SUM(CASE WHEN status='SUCCESS' AND issync in ('3','4') then 1 ELSE 0 END) as sumfail,
SUM(CASE WHEN status='CLOSED' then 1 ELSE 0 END) as sumclose,
SUM(CASE WHEN status is null then 1 ELSE 0 END) as sumunflag
from tb_r_orderdata
group by tb_r_orderdata.finishtime ;
MySQL treats booleans as integers in a numeric context, with "1" for true and "0" for false. You can simplify your query to:
select o.finishtime as date ,
COUNT(*) as sumall,
SUM(status = 'SUCCESS' AND issync = '1') as sumpaid,
SUM(status = 'SUCCESS' AND issync in ('3', '4')) as sumfail,
SUM(status = 'CLOSED') as sumclose,
SUM(status is null) as sumunflag
from tb_r_orderdata o
where tb_r_orderdata.finishtime is not NULL
group by o.finishtime ;
This also removes NULL finish times.
