[SOLVED] Timestamp, date and calculations

[jakeoh]

Hi,

 

I want to have mySQL return users that went to my site in the last 7 days. When a user logs in or uses the website, the 'timestamp' column in the database is updated with the current timestamp.

 

The MySQL query I have so far to get the list of active users in the past 7 days is as follows:

 

$q = "SELECT username, first_name, last_name FROM ".TBL_USERS." WHERE timestamp > (UNIX_TIMESTAMP() - '604800000') ORDER BY timestamp DESC,username";

 

This query however get the users that were active more than 7 days ago.

 

What is wrong with it? How would you build your query?

Sorry, I somehow thought timestamp was calculated in milliseconds.

 

Using 604800 instead of 604800000 solved it.

You really should be using INTERVAL 7 DAY for this.
