Double Booking Prevention?

[Maths9876]

Hi,


Making a Database that books training sessions and want to make sure that a training session cannot occur at the same time and date as another one.
Looked everywhere and tried different methods but no luck!
Thanks.

You may get some ideas from this material in the code repository re Room Booking/availability.

Good luck.
