select statement

Hi Guru's

I need your help to build sql statement. Please help. I have a table contain two columns.

COL_1 COL_2
2 10
7 5
8 15
10 20
9 25

I want a query which should check the range(COL_1) first and then return the least (COL_2) within that range of COL_1.

For Example If I give input for COL_1 as 5 it should return me value of COL_2 5.

I am using Oracle 8i.

Thanks In Advance.

set serveroutput on
create or replace procedure rangs(range number) is
range1 number;
range2 number;
range3 number;
begin
select max(col1) into range2 from rang;
select min(col2) into range1 from rang;
if range >= range1 and range <= range2 then
select min(col2) into range3 from rang where col2 <= range;
end if;
dbms_output.put_line('least value in col2:'||range3);
end;

let me know if this what ur looking at

regards

Thank you very much. I know this can be done in PL/SQL. Actually I am looking for a single select statement. Can it be done?

Thanks In Advance.

please be more clear

TWO values should define a range, shouldn't they?
If the input is 5 what's the second limit?

With two limits the thing looks easy:

Code:

---

select min(col_2) from the_table
where col_1 between :lower_limit and :upper_limit

---

Is that you expect?
