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;
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:

Hope this helps.
MySQL does not currently support window functions, so over() will only yield syntax errors (or garbage, if it's accepted regardless).
MySQL Doesn't have window functions until the most recent release: MySQL 8 (release in April, 2018). MS SQL Server also accepts OVER clause.
The syntax is:
function(col1) OVER (PARTITION BY col2 ORDER BY col3)
