Hi,
I have a simple table with singup timestamps
What I would like to do is to create a table as shown below that displays the counts per our for the past n dates.
I can do this with a function but is there an easy way to use recursive queries?
Counts per hour for given date
HR 2020-04-01 2020-04-02 ... 2020-04-10
00 38 33 36
01 33 26 18
02 26 36 17
03 36 18 10
04 18 17 3
05 17 10 3
06 10 3 6
07 3 3 10
. 3 6 13
. 6 10 22
. 10 13 12
22 13 22 9
