Hi everybody,

I have the following table:

I want to add up the count column grouped by theme and receiver for the dates included in the dates column.
So I have the following query:

       SELECT SUM(A.count),
   A.theme,
                 A.receiver,
                     A.dates
FROM my_table A
INNER JOIN my_table B
              ON A.theme=B.theme
            AND A.receiver=B.receiver
AND A.date=ANY(B.dates)
GROUP BY A.theme,A.receiver, A.dates;

The result of the query is:

sum | theme | receiver |                                     dates

The result is wrong. I don't know what it is wrong at my query.
Please help.

Best,
