SQL and DateTime - How do I select all rows that have existed for a specific time period?

I have a table with a row named time of type DATETIME.

How can I select all rows which 'live' no more than 5 days?

Or in other words, how can I grab data which has timestamp开发者_JAVA技巧 not more then 5 days ago?

My request:

SELECT * 
FROM `stats` 
WHERE `domain` = 'test.com' AND DATEADD(NOW(), interval -5 day) > 'accept_date'

accept_date is the real name of a row. So , with that code I got:

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') > 'accept_date' LIMIT 0, 30' at line 1

It depends on the RDBMS but in MySQL it would be

where date_add(now(), interval -5 day) > time

or

where datediff(now(), time) < 5

The first means "120 hours have passed since", the second means "5 calendar days have passed since".

time is a terrible column name, by the way. Time of what?

'accept_date' is not the name of a column - it's a character literal.

You want

AND DATE_ADD(NOW(), interval -5 day) > accept_date

(note the missing single quotes ' around the column name)

GETDATE() is DB specific, yet:

select * from TABLE where (GETDATE() - time) <= 5
