MySql using correct syntax for the over clause

Question

What is the correct syntax to get the over clause to work in mysql?

I would like to see the total sms's sent by each user without grouping it with the group by clause.

SELECT 
    username, 
    count(sentSmsId) OVER (userId) 
FROM 
    sentSmsTable,
    userTable
WHERE
    userId = sentUserId;

Answer 1

MySQL 8 has got the window functions! Therefore, you can write your query in it like this:

SELECT username, 
       count(sentSmsId) OVER (partition by userId) 
FROM sentSmsTable
JOIN userTable ON userId = sentUserId;

There is no OVER clause in MySQL that I know of, but here is a link that might assist you to accomplish the same results:
