Question

I’m trying to write an SQL Statement that needs to loop through a list of departments, kind of like a For Each.

Heres what I have so far.

SELECT DISTINCT AVG(salary),assigned->name
FROM edu_ucla_cs241_termproj_schema.InstructorImpl
WHERE assigned->name = 'Anthropology'

This will give me a table of
Avg Salary Department
90.15 Anthropology

However, I want to loop through each department. Can I make this query take a variable and loop through each department name?

Answer 1

Can you not use

SELECT  AVG(salary),
        assigned->name
FROM edu_ucla_cs241_termproj_schema.InstructorImpl
GROUP BY assigned->name
