I have a phonenumber field like:
**phonenumbers**
0729643482
0723412678
0734231567
0745297334
0729643482
0720606706
0729643482
0720606706
There are thousands of entries. I wanted to get top 10 phonenumbers with greatest count. this can be displayed as
**phonenumber count**
0729643482 3
0720606706 2
.
.
.
(entry 10) 1
From some of the few related questions i understand i can use rank() then group by but i have never done this before. Here is what i have:
select phonenumber,cnt FROM
(select phonenumber, cnt, rank() over (partition by phonenumber order by cnt desc) rnk
from (select distinct phonenumber, count(phonenumber) cnt
from ozekiout
group by phonenumber
order by phonenumber, count(phonenumber) desc)
)
where rnk = 1;
You don't need the rank function, you can use a normal count with TOP 10
:
SELECT TOP 10 phonenumber, [count] = COUNT(*)
FROM ozekiout
GROUP BY Phonenumber
ORDER BY [count] DESC;
If you want to include more than 10 results if there are ties eg
Phonenumber count
01111111111 18
01111111112 15
01111111113 15
01111111114 14
01111111115 13
01111111116 13
01111111117 12
01111111118 12
01111111119 10
01111111120 10
01111111121 10
01111111122 10
.... CUT OFF
01111111122 9
you can use:
SELECT TOP 10 WITH TIES phonenumber, [count] = COUNT(*)
FROM ozekiout
GROUP BY Phonenumber
ORDER BY [count] DESC;
尝试这个 :
select phonenumber,Count(*) as count from ozekiout group by phonenumber order by count desc limit 10;
SELECT TOP 10 phonenumber, [count] = COUNT(*) FROM ozekiout GROUP BY Phonenumber ORDER BY [count] DESC;
Works ryt....thank you guys
