Filter data by interval time (between) in mysql

Oftentimes we need to filter or select data in mysql by the interval time, luckily mysql provide an INTERVAL query, here is how we do it.

For example you search for data that made in this week

SELECT * FROM `tableName` WHERE created_at < NOW() - INTERVAL 1 WEEK  

the unit is flexible, you can change WEEK, to day, hour, month even year
