Hi,
I have a table called Bookings which has two important columns;
Booking_Start_Time and Booking_End_Time. These columns are both of type
DATETIME. Given any day how can I calculate how many hours are available
between the hours of 09.00 and 17.30 so a user can see at a glance how many
hours they have unbooked on a particular day, can this be done with a query
or do I have to work it out with PHP?
Thanks for your help
