This should do it:

UPDATE Bookings
SET
Booking_Start_Date = CONCAT(DATE_FORMAT(Booking_Start_Date, 
'%Y-%m-%d'), '09:00:00'),
Booking_End_Date = CONCAT(DATE_FORMAT(Booking_End_Date, '%Y-%m-%d'), 
'17:30:00');

If you are using version 4.1.1 or newer the DATE_FORMAT function could 
be replaced by:
DATE(Booking_Start_Date)

HELP With UPDATE Query in mySQL:

Hi,

I have two columns in my Bookings table of type DATETIME -
Booking_Start_Date and Boking_End_Date. How can i update every row so that
all of the times for Booking_Start_Date are 09.00 and all of the times for
Booking_End_Date are 17.30, without affecting any of the dates?
Thanks for your help
