iReport different query to text field

[wszystkielogizajete]

Hi I want to make reports about vulnerabilities on my computer during year something like that:

Time period[months ago]	12	11	10	9	8	7	6	5	4	3	2	1
Vulnerabilities	?	?	?	?	?	?	?	?	?	?	?	?

I have good query : SELECT sum(vulnerabilities) FROM fact_all_date
WHERE now()-fact_all_date.day < INTERVAL 'in month'  but now i have problem how to change query to include "Time period" in query for every field with question mark. Any ideas?
