Question

How will the MySql statement look like? For example:

SELECT * FROM users WHERE ……. ???

Is it going to be time less than – milliseconds? How can I put the current time ?

Answer 1

SELECT COUNT(*) FROM users 
WHERE TO_DAYS(NOW()) - TO_DAYS(`date_registered`) <= 7

This query is or may be suboptimal for your specific case because there is very little known about the structure of your database. For more information please refer to the manual.
