I hope I can explain this clearly. I have two queries I'm running in a
report.
The first one is:
select dr.store_id,
store.suffix,
store.sort_id,
year as data_year,
(dr.layaway_starting_balance
+
dr.layaway_net_change)
as
layaway_balance,
(dr.loan_starting_balance
+
dr.loan_net_change)
as
loan_balance,
dr.inventory_starting_balance
+
inventory_net_change
as
inventory,
(dr.loan_starting_number
+ dr.loan_number_change) as number_loan,
(dr.loan_starting_balance + dr.loan_net_change)
/(dr.loan_starting_number + dr.loan_number_change) as loan_balance_avg
from daily_runbalance dr
join store on
(dr.store_id = store.store_id)
where dr.date = '2006-06-30'
and dr.store_id = 4
and store.store_id = 4
The second is very long so I'll just post the relevant pieces.
select dr.store_id,
store.short_name,
store.sort_id,
ds.year as data_year,
sum(ds.pulled_loan_total) as loan_pulls,
sum(ds.renew_loan_amount) as loan_renewals,
from daily_runbalance dr
join daily_summary ds on (dr.store_id =
ds.store_id and dr.date = ds.date)
join cash on (dr.store_id = cash.store_id and
dr.date = cash.date)
join store on (dr.store_id = store.store_id)
where dr.date between '2006-04-01' and
'2006-06-30'
and dr.store_id = 4
group by dr.store_id, store.sort_id,
store.short_name, ds.year
As you can see the two queries have different time frames. The first
one has one date, the second one has a range of dates.
What I'm trying to accomplish is to get two percentages. Both have one
element from one table divided by an element in the other table.
sum(ds.pulled_loan_total)/sum(dr.loan_starting_balance +
dr.loan_net_change)*100 as pulls_percent,
and
(sum(ds.renew_loan_amount)/sum(dr.loan_starting_balance +
dr.loan_net_change))*100 as renew_percent,
No matter which query I place them in it gives me the wrong data because
of the time frames. How can I get the correct data?
Thanks
