I tried the following query but it didn't give me result I am looking for.
Select rs.Name, rs.Country, rs.Status, Count(*) as total from (
SELECT Name, Country, Status, Rank()
over (Partition BY Name
ORDER BY Country DESC ) AS Rank
FROM table1 ) rs WHERE Rank <= 3

Answer 1

You can use the following query:
;With CTE AS (
SELECT Name, Country, Status,
COUNT(*) OVER (PARTITION BY Name, Country) AS cnt
FROM mytable
), CTE2 AS (
SELECT Name, Country, Status,
DENSE_RANK() OVER (PARTITION BY Name ORDER BY cnt DESC, Country) AS seq
FROM CTE
)
SELECT Name, Country, Status, COUNT(*) AS Total
FROM CTE2
WHERE seq <= 3
GROUP BY Name, Country, Status
ORDER BY Name, Country
In case of the ties, the query picks the Country having the 'smallest' name in comparison to the other countries.

Answer 2

Your original query was definitely in the right direction (I even used it to figure out what output you wanted). However, your desired output is the result of several aggregations, not just a single analytic function. In the query below I first aggregate to get totals, then use rank to retain the first 3 groups. In case of ties this query picks the country which comes alphabetically first.
SELECT t.Name,
t.Country,
t.Status,
t.Total
DENSE_RANK() OVER (PARTITION BY t.Name ORDER BY t.Total DESC, t.Country) AS rn
FROM
(
SELECT Name, Country, Status, COUNT(*) AS Total
FROM table1
GROUP BY Name, Country, Status
) t
WHERE rn <= 3

Answer 3

try this one..
Select rs.Name, rs.Country, rs.Status, Count(*) as total from rs(
SELECT Name, Country, Status, Count(status) from mytable
group by status order by Count(status) desc
) rs limit 3

Answer 4

How about:
select Top 3 with ties * FROM(
select Name, country, Status
, count(*) as total
, count(*) over (Partition BY Name, Country) as rank
from mytable
group by Name, Country, Status
) i
order by i.rank desc

Answer 5

Could you please try below SQL script
;with cte as (
select *, COUNT(*) over (partition by country) cnt
from table1
), t3 as (
select distinct top 3 country, cnt
from cte order by cnt desc
)
select distinct *
from cte
inner join t3 on cte.country = t3.country
Output is as follows

Answer 6

Use below query.
;WITH CTE
AS
(
SELECT NAME,COUNTRY,ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY COUNT(COUNTRY) DESC) ROWNO FROM TBLCOUNTRY
GROUP BY NAME,COUNTRY
)
SELECT C.NAME,C.COUNTRY,C.STATUS,COUNT(C.STATUS) TOTAL FROM TBLCOUNTRY C INNER JOIN CTE ON
C.NAME=CTE.NAME AND C.COUNTRY=CTE.COUNTRY AND CTE.ROWNO<=3
GROUP BY C.NAME,C.COUNTRY,C.STATUS
ORDER BY NAME,COUNTRY DESC, STATUS DESC
