SQL-返回编号最高的标题

Question

I want to return from my database the title with the most eps. With the following code I do get all the titles back.

SELECT titel, MAX(aantalafleveringen) FROM imdb.tvserie GROUP BY titel;

Hope that somebody can explain me what I'm doing wrong.

Answer 1

smth like his:

SELECT distinct titel, MAX(aantalafleveringen) over (partition by titel) 
FROM imdb.tvserie
ORDER BY max desc
LIMIT 1
;

Answer 2

Use Order by and Limit

SELECT titel,
       Max(aantalafleveringen) AS max_aantalafleveringen
FROM   imdb.tvserie
GROUP  BY titel
ORDER  BY max_aantalafleveringen DESC -- orders the result in descending order
LIMIT 1 -- filters the first record

Answer 3

If you want the maximum of maximum per groups , you just really want the global maximum.

This is equivalent with the other answers, but much more simple:

SELECT   titel, aantalafleveringen
FROM     imdb.tvserie
ORDER BY aantalafleveringen DESC
LIMIT    1
