delete from database after time

[gavin.sibley]

I am trying to find a way of deleting entries from a database after a certain time, and also when there is another field in the database set to 0.

 

i have got so far with the code (will delete when other field is at 0) but nothing happens when i try to add in the time. my code im trying to use is below

 

mysql_query("DELETE FROM temp_users WHERE book_stage='0' and WHERE time() > [creation+60]");

 

creation being the name of the field in the database that holds the unix time stamp.

 

i need the entry to be deleted one hour after it was created if the book_stage hasnt been changed to 1 during this hour.

 

many thanks,

gavin

I think you want to setup another PHP script and run a cron job. The database table will not update itself without something enacting on it.

mysql_query("DELETE FROM temp_users WHERE book_stage='0' and WHERE time() > [creation+60]");

 

A proper query only has the WHERE keyword once.

 

DELETE FROM temp_users 
WHERE condition_1
AND condition_2
AND condition_3

 

The book_stage condition looks OK (although if it is an integer field, I would not use quotes around it).

 

For the time condition, you need to use mySql functions, or do the calculation in PHP and insert the value. Using the mySql functions would be the preferred method.

 

CURRENT_TIME > DATE_ADD(creation, INTERVAL 60 MINUTE)
