I would like to query as follows: DISTINCT orderby, CONCAT status and COUNT status

+----------+---------------+--------------+
| orderid  | status_concat | status_count |
+----------+---------------+--------------+
| R-R34184 | 0,1,2         | 3            |
+----------+---------------+--------------+
| R-R34185 | 0             | 1            |
+----------+---------------+--------------+

I tried several codes, any subquery, grouping, but it doesn't come together. Thanks if anyone can help.

Answer 1

That's just group by and distinct in aggregate functions group_concat() and count() :

select orderid, 
    group_concat(distinct status order by status) status_concat, 
    count(distinct status) status_count
from mytable
group by orderid

Answer 2

I think you want distinct :

select orderid, group_concat(distinct status order by status), count(distinct status)
from t
group by orderid;
