Much like in this answer, how can I achieve the same thing in SQL?
I want to group the data first by site, then by date and then have a count that shows number of bookings on that date.
The result would be something like this:
Site1   2021-03-04      9
Site1   2021-03-05      5
Site1   2021-03-06      4
Site2   1900-01-01      1
Site2   2020-12-30      1
Site2   2021-01-04    325
Site2   2021-01-05    520
