Question

I want to return all records that were added to the database within the last 30 days. I need to convert the date to mm/dd/yy because of display purposes.

create_date between DATE_FORMAT(curdate(),'%m/%d/%Y') AND (DATE_FORMAT(curdate() - interval 30 day,'%m/%d/%Y')) 

My statement fails to limit the records to the last 30 days – it selects all the records.

Can anyone point me in the right direction? It feels like I am close.

Thanks and have a great week.

You need to apply DATE_FORMAT in the SELECT clause, not the WHERE clause:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

Also note that CURDATE() returns only the DATE portion of the date, so if you store create_date as a DATETIME with the time portion filled, this query will not select the today’s records.

In this case, you’ll need to use NOW instead:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()
