Hi to all,
I need help to build a statement in order to select all days free from
events in a specific time range.
E.g.:
- Range(-MM-DD) from 2011-01-01 to 2011-02-01.
- Event 1 from 2011-01-02 to 2011-01-08
- Event 2 from 2011-01-06 to 2011-01-12
- Event 3 from 2011-01-18 to 2011-01-21
Thanks Simon, GREAT solution!!!
