如何在SQL中查找所有最常用的值？

Question

我將如何去顯示全部 SQL中最常見的值？

所以我有查詢以顯示下面最常見的值。

SELECT name, COUNT(*) AS popularity 
FROM cattwo 
GROUP BY name 
ORDER BY popularity DESC 
LIMIT 1; 

    +----------+------------+ 
    | name  | popularity | 
    +----------+------------+ 
    | cat22610 |   7 | 
    +----------+------------+ 

然而，當我顯示前10個最常用的值結果是...

SELECT name, COUNT(*) AS popularity 
FROM cattwo 
GROUP BY name 
ORDER BY popularity DESC 
LIMIT 10; 

    +----------+------------+ 
    | name  | popularity | 
    +----------+------------+ 
    | cat22610 |   7 | 
    | cat68704 |   7 | 
    | cat14153 |   7 | 
    | cat52476 |   7 | 
    | cat4556 |   7 | 
    | cat64173 |   7 | 
    | cat5586 |   7 | 
    | cat89302 |   6 | 
    | cat97131 |   6 | 
    | cat42010 |   6 | 
    +----------+------------+ 

目標是與人氣最高，以顯示所有的貓。像這樣的東西。

+----------+------------+ 
| name  | popularity | 
+----------+------------+ 
| cat22610 |   7 | 
| cat68704 |   7 | 
| cat14153 |   7 | 
| cat52476 |   7 | 
| cat4556 |   7 | 
| cat64173 |   7 | 
| cat5586 |   7 | 
+----------+------------+ 

幫助會很好。提前致謝。

Answer 1

我想這個查詢會幫助你！

SELECT NAME, COUNT(*) AS POPULARITY 
FROM CATTWO 
GROUP BY NAME 
HAVING COUNT(*) = 
     (
      SELECT COUNT(*) AS MAX_POPULARITY 
      FROM CATTWO 
      GROUP BY NAME 
      ORDER BY MAX_POPULARITY DESC 
      LIMIT 1 
     ); 

Answer 2

SELECT name, COUNT(*) AS popularity 
FROM cattwo 
GROUP BY name 
HAVING COUNT(*) = 
     (
      SELECT COUNT(*) AS popularity 
      FROM cattwo 
      GROUP BY name 
      ORDER BY popularity DESC 
      LIMIT 1 
     ) 
LIMIT 10;
