Ivan G :
Table:
id | value
---+-----------
1 | Monday
2 | Tuesday
3 | Tuesday
4 | Wednesday
I need it to display like:
value | count | id1 | id2
----------+-------+-----+-----
Monday | 1 | 1 |
Tuesday | 2 | 2 | 3
Wednesday | 1 | 4 |
But using the Group By function will not work for obvious reasons ("id" is not contained in either the aggregate function or the GROUP BY clause).
However, I still need this done and I have exhausted my knowledge of juggling the variables into temp tables. Need this on SSMS, Any help is appreciated, thank you.
Gordon Linoff :
You just want string aggregation. Here is a typical method:
select value, count(*), string_agg(id, ',') as ids
from t
group by value;
If you want the values in two columns, you can use MIN() and MAX():
select value, count(*),
min(id) as id1, coalesce(max(id), min(id)) as id2
from t
group by value;
