How can I exclude a user with a specific id in MySQL

How can I exclude a user with a user_id of 1 for example from the following query below?

Here is My MySQL code.

"SELECT users.*, COUNT(*) as coun, users_comments.user_id 
FROM users_comments
INNER JOIN users ON users_comments.user_id = users.user_id
GROUP BY users_comments.user_id 
ORDER BY coun DES开发者_运维百科C
LIMIT 5"

SELECT users.*, COUNT(*) as coun, users_comments.user_id 
FROM users_comments
INNER JOIN users ON users_comments.user_id = users.user_id
WHERE users.user_id != 1 <---------------
GROUP BY users_comments.user_id 
ORDER BY coun DESC
LIMIT 5

SELECT users.*, COUNT(*) as coun, users_comments.user_id 
FROM users_comments
JOIN users ON users_comments.user_id = users.user_id
WHERE users.user_id not in(1,3) 
GROUP BY users_comments.user_id 
ORDER BY coun DESC
LIMIT 0,5
