The very basics
Infinite looping
Processing trees with recursive CTE
Processing graphs with recursive CTE
Instruction
Great job! With this kind of looping queries, it's important to always have a termination check that will end the query at some point. Let's see what happens if we forget about that.
Exercise
Look at the template. It's essentially the first example query from the previous section, but we removed the termination check. Try to run the query and find out for yourself what happens when the recursion never stops.
