如何在 SQL 中显示 ALL 最常见的值？

所以我有查询在下面显示最常见的值。

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

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

但是，当我显示前 10 个最常见的值时，结果是......

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 |
    +----------+------------+

目标是展示所有人气最高的猫。像这样的东西。

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

我想这个查询会对你有所帮助！

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
        );
