help me write select query

i have 3 tables follows

subscriber ############################ subscr_id parent id --------- --------- 1 100 2 100 3 101 4 101

so there can more 1 subscr_id under 1 parent id (these called locations). other tables are

products ############################ subscr_id products businessline --------- -------- ------------- 1 5100 100 1 1100 200 2 3100 300

and

addons ############################ subscr_id products businessline addons --------- --------- ------------ ------ 1 5100 100 1 1 5100 100 5 1 5100 100 30 1 1100 200 5 1 1100 200 25

now have 4 parameters -1) products 2) businessline 3) addons 4) parent id users give. none of 1,2,3 mandatory.

for input parent id output true else false based on next conditions

if product given result true if 1 of locations of parent have entries products = given product input if business given result true if 1 of locations of parent have entries businessline = given business line if both business , product given result true if 1 of locations of parent have entries businessline = given business line , product = given product if addons given result true if 1 of locations of parent have entries addons = given addon in addons tables numerous conditions possible

i want write single select query

i had tried in local database based on on data. procedure follows in next procedure used notations are

subscr_id sid parent id pid businessline bl

products pro

declare given_pro number(5):=&given_pro; given_bl number(5):=&given_bl; given_addons number(5):=&given_addons; cursor cur select distinct s.pid subscriber s,product p,addons (nvl(given_pro,1)=given_pro , nvl(given_bl,1)=1 , s.sid=p.sid , a.pro=given_pro , p.pro=given_pro , a.pro=p.pro , a.sid=s.sid , p.sid=a.sid) or (nvl(given_bl,1)=given_bl , nvl(given_pro,1)=1 , a.bl=given_bl , p.bl=given_bl , s.sid=p.sid , a.bl=p.bl , a.sid=s.sid , p.sid=a.sid) or (nvl(given_bl,1)=given_bl , nvl(given_pro,1)=given_pro , a.pro=given_pro , p.pro=given_pro , a.bl=given_bl , p.bl=given_bl , s.sid=p.sid , a.pro=p.pro , a.bl=p.bl , a.sid=s.sid , p.sid=a.sid) or (nvl(given_addons,1)=given_addons , nvl(given_bl,1)=1 , nvl(given_pro,1)=1 , a.sid=s.sid); rec cur%rowtype; begin open cur; loop fetch cur rec; exit when cur%notfound; dbms_output.put_line(rec.pid ||' hello'); end loop; close cur; end;

this procedure give pid
