Help with Update SQL

Question

Hi,
I have the following SQL and I need your help.
declare
i_howMany number;
begin
i_howMany := ?;
update NumberRange
set lastNumberAssigned = lastNumberAssigned + i_howMany
where rangeType = ? and lastNumberAssigned < maxNumber
returning (lastNumberAssigned - i_howMany + 1), lastNumberAssigned into ?, ?;
end;
Is it possible to refactor the above SQL to return a ResultSet with 2 Number fields, i.e. fromNumber and toNumber?

Hi,
The table NumberRange has the following fields and data.
This table is used to store the number sequences for Booking ID, Invoice ID, etc.
Note that I can't use Oracle Sequences as the values are maintained by external parties, and a change to Oracle Sequences would mean a re-write of the application functionality.
NumberRange
rangeType maxNumber lastNumberAssigned
'Booking' 20000 500
'Invoice' 10000 10
There are 2 input parameters:
- i_howMany - this is used to get a range of numbers (i.e. from & to numbers) from NumberRange
- rangeType - this is used to identify the rangeType, e.g. Booking.
There are 2 output fields that contain the assigned number range (which I want to be returned in a ResultSet)
- fromNumber
- toNumber
For example:
1st parameter (i_howMany) = 5
2nd parameter (rangeType) = 'Booking'
Output fields (based on the above example) will be:
- fromNumber = 501
- toNumber = 505
I just want the 2 output fields to be in a ResultSet as the calling program will be expecting the result in a ResultSet.
