oracle query help

I have enclosed sample data and also table structure. I need help in getting the query.


select dept_id,proc_code,override_goal,goal_override_date
  from table2
 where goal_override_date between '02-jan-2014' and '11-jan-2014'
   and dept_id = 10
   and proc_code = 'CP'


select DEPT_ID, PROC_CODE, DAY_SUNDAY, DAY_MONDAY,
       DAY_TUESDAY, DAY_WEDNESDAY, DAY_THURSDAY,
         DAY_FRIDAY, DAY_SATURDAY
  from table1
 where dept_id =10
 and proc_code = 'CP';  --

Table1  is kind of maintenance table.
In Table2 values can be overridden.


Requirement

Check to see if there is data in table 2 for the date range . If table2 has no value then take value from table1 for that day the date falls into. Any more clarification please ask me.
Sundays are all zeros.
 I want this data. and the sum for the date range.
