Hey, Loredana.
Hi Oliveiros! Nice to "see" you again!
Please advice me,
you need to sum for a certain pair (Theme, receiver) the number that
appears on count for every record whose date is in dates column, is this
correct?
Yap.
But in what record's dates column? On all of them? Or just the dates column
of the records that have that (Theme , Receiver) ?
Suppose I have
3| CRIS | rec1 | date1 | (date1,date2)
3| CRIS | rec1 | date2 | (date1,date3)
What would be your intended sum?
3 ? 6 ?
3
date2 is not on dates column for that record, but it is on the first...
Could you please show me an example of what would be the correct output
for ex for ,
CRIS | +40741775622 ?
And For
LIA | +40741775621 ?
Let's take a look at the following data:
count | theme | receiver | date

We can see that for LIA if we sum the count per day we have the following:
theme date count
LIA 2007-06-01 00:00:00+00 4
LIA 2007-06-02 00:00:00+00 2
LIA 2007-06-03 00:00:00+00 2
LIA 2007-06-04 00:00:00+00 2
Also for CRIS:
theme date count
CRIS 2007-06-01 00:00:00+00 3
CRIS 2007-06-02 00:00:00+00 1
CRIS 2007-06-03 00:00:00+00 1
CRIS 2007-06-04 00:00:00+00 3
With the following query
SELECT SUM(B.count),
A.theme,
A.receiver,
A.dates
FROM view_sent_messages A
INNER JOIN view_sent_messages B
ON A.theme=B.theme
AND A.receiver=B.receiver
AND B.date=ANY (A.dates)
GROUP BY A.theme,A.receiver, A.dates;
I obtain the following result:
sum | theme | receiver | dates
-----+----------+---------------------+--------------------------------------------------------------------------------

We can see that for example for the first row, the sum 8 it is correctly
calculated because if we sum the count for the days from dates column.
If we take a look at the fourth row we can see that the sum it is not
correct: it should be taken values for the count only for the date
2007-06-04.
The same problem it is at the eigth row.
