MySQL: Delete all rows older than 10 minutes

Question

I have a timestamp field in my table. How do I delete records older than 10 minutes old?

Tried this:

DELETE FROM locks WHERE time_created < DATE_SUB(          


        

Answer 1

The answer is right in the MYSQL manual itself.

"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"

Answer 2

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)
