I have a duedate column(datetime format) that specifies the due date of a ticket, now i need to get 'Due today' tickets base on the comparison between now() with duedate. i.e 2010-04-29 02:00 vs 2010-04-29 10:00 would return true in this matter.

MySQL has the ability to compare two different dates written as a string expression. When you need to compare dates between a date column and an arbitrary date, you can use the DATE() function to extract the date part from your column and compare it with a string that represents your desired date.
The right way to compare date only values with a DateTime column is by using <= and > condition. This will ensure that you will get rows where date starts from midnight and ends before midnight e.g. dates starting with '00:00:00.000' and ends at "59:59:59.999".
To count the difference between dates in MySQL, use the DATEDIFF(enddate, startdate) function. The difference between startdate and enddate is expressed in days.
The NOW() function returns the current date and time. Note: The date and time is returned as "YYYY-MM-DD HH-MM-SS" (string) or as YYYYMMDDHHMMSS.
Use DATE(NOW()) to compare dates
DATE(NOW()) will give you the date part of current date and DATE(duedate) will give you the date part of the due date. then you can easily compare the dates
So you can compare it like
DATE(NOW()) = DATE(duedate)
OR
DATE(duedate) = CURDATE()

Compare date only instead of date + time (NOW) with:
CURDATE()
