3-5
5-7
7-9
9-11
11-1
If all you want is just the unique timing then use:
SELECT timing from class_Table group by timing
Unless there's other information you are trying to get from this query. Is there any additional info you can give us?

Let suppose there four entries in table as shown below.I want only Row 1 and 2 in resultset.
The vice versa case of 1 and 2 in Row 3 and 4 should be excluded. Please suggest a query for that
Pk Col1 Col2 Col3 Col4
1 A B 20 30
2 E D 40 50
3 B A 20 30
4 D E 40 50
WHERE Col1 < Col2 immediately comes to mind. Actually, that would give you rows 1 and 4, but I presume that's good enough for yuor purposes.

In my table 2 columns are there. Name and Marks. Something like this.
Name Marks
---------- -----------
AAA 50
BBB 48
CCC 54
AAA 52
DDD 55
BBB 60
AAA 66
I need to retrieve from the table something like below
Name No.of.attempts Max Mark
------- ---------------- ------------
AAA 3 66
BBB 2 60
CCC 1 54
DDD 1 55
You should do like:
select name,count(name) as no_of_attempts,max(marks)
from table_name
group by name
fddle demo here
you can do it like this
select name,COUNT(name) as nameCount,MAX(markes) as marks from #abc group by name

Assuming you do talk about SQL (as implied by count and distinct):
select country_isocode,
sum(part_gold) as part_gold,
sum(part_silver) as part_silver,
sum(part_bronze) as part_bronze
from the_table
group by country_isocode;
