Need SQL Query only... Not PL/SQL.

Hi

I have ta table with the following col and values:

Table: T1
==========
Co1 Col2
----------
A 10
B 15
C 20
D 05
E 30
F 15
G 25
----------
My criteria is:
================
print all the records from table
where sum(col2) is <=45

It means: logic is something like
col2:=record1+record2+record3+....
Col2:=10+15+20=45
If total of the Col2 is upto 45, i need to print, other wise comeout.

So the sample output should be:
Co1 Col2
----------
A 10
B 15
C 20
=====================

I know that we can write the PL/SQL to get the output using CURSOR.
But, i need to write this Query only by SQL.

Could some one assist me in this regards.

Thanks
Anandharaj
