Comparing dates in MYSQL is not working after MYSQL upgrade

I have a query that has run for multiple years, we recently upgraded (5.0.45).  It appears that comparing using the Date() function no longer is working correctly.

Attaching the query below, the ship_dt column is a timestamp column and we are only wanting to compare the date and not the entire timestamp.

As mentioned this worked perfectly fine under 4.x

Any help would be greatly appreciated.
SELECT DISTINCT a.orderid FROM orders a WHERE a.orderstatus=2 AND DATE(a.ship_dt)='2008-06-26'

My suggestion would be to use the date_format inyour WHERE clause, since this is a timestamp you have the hh:mm:ss along with that value, you will need to strip that portion of the date/time off and just compare the '%Y-%m-%d' in your query.

try something like:

SELECT DISTING A.orderid FROM orders WHERE A.orderstatus = 2 AND DATE_FORMAT(a.ship_dt, '%Y-%m-%d')='2008-06-26'

Good luck!

I'm glad it worked for you, MySQL 5 is just more standardized. What's with the grade?
