# 3639 Sub-Queries Nested within Aggregates in SELECT Statements Can Return Incorrect Results

I have a problem with Subselects returning the same value even though they have different Where clauses.It seems to be ignoring part of the Where clause that has "texp2.expense_code='LNC".

If I omit the "/sum(income)" it returns proper values. It appears to me EDB thinks both subselects are the same and will get the value for the 2nd subselect from the cache of the 1st subselect.

select
sum((select expense_amount from Expenses texp  where 
texp.cust_id=tc.cust_id   and texp.expense_code='PRK')) / 
sum(income)  as Avg_PRK
,sum((select expense_amount from Expenses texp2 where 
texp2.cust_id=tc.cust_id  and texp2.expense_code='LNC'))/ 
sum(income)  as Avg_LNC
from customers tc
