Importing and creating relationships in base [closed]
So I have an .xlsx file I need to import into Base. It has two tables and I need to create a relationship between the two tables. I can import the file just fine by opening it in Calc first, saving it, then connecting to it when I open Base. However, when I try to create a relationship I get the error "This database does not support relations."
What do I need to do? What am I doing wrong?
