i am working with a table similar to the one below:

-------------------------------
person | amount
-------------------------------
p1 | 100
p1 | 150
p1 | 600
p1 | 100
p1 | 300
p1 | 200
p1 | 50
p1 | 100

i want to get any row or combination of rows where the [amount] field adds up to 300
eg:
( 300 ) or (100,100,100) or (100,200) or (100,50,150) etc

is there any function available that can achieve this?

i would really appreciate any assistance.

No, there is not.

As this is a classical (but not obvious) homework, post what you tried.

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version with 4 decimals.

Post a working Test case: create table and insert statements along with the result you want with these data.

Regards
Michel
