Does this seem right?
druid=> SELECT COUNT(*) FROM acctrans;
count
----- 0
(1 row)
druid=> SELECT client_id, SUM(tramount) FROM acctrans GROUP BY client_id;
client_id|sum
---------+--- |
(1 row)
If there are no rows in the table then shouldn't the result be no rows
when GROUP BY is used? Further, What about this?
druid=> SELECT SUM(tramount) FROM acctrans;
sum
---
(1 row)
Shouldn't that be 0.00?
What will the NUMERIC or DECIMAL types do in these situations? It
looks like INTEGER has the same behaviour as MONEY (which tramount is.)
