Question

Hi all,
I have a query
SELECT schedule_id ,COLUMN_VALUE,player_team_coach,current_player_team_id
FROM stat_totals where SCHEDULE_ID = '20040809NFL--WASHINGTON0' AND COLUMN_ID ='FPLKICK_PR_YARD';
this returns me
schedule_id column_value player_team_coach team_id
20040809NFL--WASHINGTON0     11     13373     8831
20040809NFL--WASHINGTON0     15     1953480     8831
20040809NFL--WASHINGTON0     46     2026423     8810
for a given schedule there are only two teams playing.whenever team_id = 8831, i need 8810 column_values which is equal to 46
and whenever team_id = 8810 , i have to sum up all the column_values of 8831 which is 11+ 15=26 .
My output must look like the one below.
schedule_id sum( column_value) player_team_coach
     8831     46 13373
     8831     46 1953480
     8810     26 2026423

Hi,
I have got three tables named stat_totals,schedules, teams
stat_totals has the following columns schedule_id,stat_type_id ,column_id, player_team_coach(player_id),league_id,column_value,current_player_team_id
schedules has the following columns schedule_id,schedule_date,home_team_id,visitor_team_id,league_id,season_id
teams has the following columns team_id,team_name,location_id,division_id,league_id
select player_team_coach,current_player_team_id current_team_id,HOME_TEAM_ID,VISITOR_TEAM_ID,c.team_id,
SUM(to_number(column_value, '9999')) pr_yard,
0 avg_yds_unit from stat_totals a, schedules b, teams c
where a.schedule_id = b.schedule_id and a.stat_type_id = 'PPG'
and a.column_id = 'FPLKICK_PR_YARD' and b.league_id = 'NFL'
and a.SCHEDULE_ID = '20040809NFL--WASHINGTON0'
-- and b.schedule_date between '01-DEC-2007' and '31-DEC-2007'
and b.game_status_id = 143
and a.current_player_team_id in (
select CASE WHEN a.current_player_team_id = HOME_TEAM_ID THEN visitor_team_id
when a.current_player_team_id = visitor_team_id then HOME_TEAM_ID
else 0 end team_id from stat_totals a, schedules b, teams c
where a.schedule_id = b.schedule_id and a.stat_type_id = 'PPG'
and a.column_id = 'FPLKICK_PR_YARD' and b.league_id = 'NFL'
and a.SCHEDULE_ID = '20040809NFL--WASHINGTON0'
-- and b.schedule_date between '01-DEC-2007' and '31-DEC-2007'
and b.game_status_id = 143 and a.current_player_team_id = c.team_id
and a.current_player_team_id = c.team_id -- and c.primary_conf_id = 5
group by player_team_coach, current_player_team_id,HOME_TEAM_ID,VISITOR_TEAM_ID,c.team_id
player_id          current_team_id   home_team_id  visitor_team_id   c.team_id    column_value
*13373 8831 8831 8810 8831 11*
*2026423 8810 8831 8810 8810 46*
*1953480 8831 8831 8810 8831 15*
whenever current_player_team_id = home_team_id then i need to total the opposing teams column_values
in the above example for current_team_id = 8831 ,the opposing team is 8810, so we need to sum up all the column_nalues of 8810 which is equivalent to 46.
similarly for current_team_id = 8810 the opposing team is 8831 , so we need to sum up all the column_nalues of 8831 which is equivalent to 26.
My output has to look like this
player_id          current_team_id   home_team_id  visitor_team_id   c.team_id    column_value
*13373 8831 8831 8810 8831 46*
*2026423 8810 8831 8810 8810 26*
*1953480 8831 8831 8810 8831 46*
