Selecting the most popular destination of my database on mysql - mysql

Question

I've created 3 tables:
CREATE TABLE participe
(
IDadherent INTEGER,
IDsortie INTEGER,
CONSTRAINT pk2 PRIMARY KEY (IDadherent, IDsortie)
);
CREATE TABLE sortie
(
IDsortie INTEGER PRIMARY KEY,
jour DATE,
Latitude_sortie FLOAT,
Longitude_sortie FLOAT
);
CREATE TABLE adherent
(
IDadherent INTEGER PRIMARY KEY,
nom VARCHAR(30),
prenom VARCHAR(30)
);
TL;DR:
Table 1) Adherent (this is the people potentially going to a set of destinations with adherentID as a primary key)
Table 2) Sortie (this is the table with the potential destinations with destinationID as a primary key)
Table 3) Participe (this table links both primary keys: AdherentID and destinationID
If I select the content of the table "participe" I get something like this:
+----------+------------+
| IDsortie | IDadherent |
+----------+------------+
| 5 | 1 |
| 5 | 3 |
| 5 | 5 |
| 4 | 2 |
| 3 | 1 |
| 3 | 4 |
| 3 | 5 |
| 2 | 3 |
| 2 | 5 |
| 1 | 1 |
| 1 | 2 |
| 1 | 3 |
| 0 | 6 |
+----------+------------+
I've attempted to order the above table and get a new table with the most popular destinations (IDsortie), expecting to get something like this:
+----------+----------------+
| IDsortie | Numeroadherent |
+----------+----------------+
| 5 | 3 |
| 4 | 1 |
| 3 | 3 |
| 2 | 2 |
| 1 | 3 |
| 0 | 1 |
+----------+----------------+
In order to achieve that glorious table I've used these queries (and failed miserably):
SELECT IDsortie, IDadherent
FROM participe
ORDER BY IDsortie DESC;
SELECT COUNT(IDsortie)
FROM participe
GROUP BY IDadherent
ORDER BY COUNT(IDadherent) ASC;
SELECT COUNT(IDsortie)
FROM
(SELECT COUNT(*) AS IDsortie
FROM participe
GROUP BY IDadherent) AS Results
One of the mysql mods has very kindly redirected me to other similar questions but I don't understand their answers, could someone please walk e through this (sorry for the inconvenience).

Answer 1

It looks like you want a single query:
SELECT IDsortie, COUNT(*) as Numeroadherent
FROM participe
GROUP BY IDsortie DESC
ORDER BY IDsortie DESC;
I'm not quite sure what your queries have to do with answering the question. Hence, it is unclear what your confusion is. The answer to your question is a simple GROUP BY query.

Answer 2

Try using the below query,
SELECT IDSortie
, COUNT(IDSortie) [Numeroadherent]
FROM Participe
GROUP
BY IDSortie
ORDER
BY IDSortie;
