Hi,
I am doing an IT-traineeship in which I have done some SQL foundation course.
Since I wanted to make my skills better, I decided to start working on a project at home.
I have an excel (Mac Numbers) sheet in which I have all my monthly/yearly expenses (rent, internet, gas, water, etc.) and I want to build it into a database which I will first manually update, and later build an app around it.
The point I am not getting is the following:
How can I design my tables (or queries) so I can get an overview for all months, without filling in my rent for each month. In the picture is an example. I have set the rent on January 2019, and set an increase from June 2019 on. How can I tell SQL I want to have the rent from January for each month, until it changes (June)?
I thought by adding a 'Recursive' column I could do something with that, but that doesn't seem very useful..
Thanks in advance!!
Patrick
