How do you use AVG in sql to manage grouped output? For example:
Given a SQL Table Employee
Name Salary City
John Doe 15000 Seattle
Jane Doe 30000 Redmond
Tim Wayne 25000 Seattle
Write a SQL query that would return the average salary per city in the format shown below:
City Salary
Seattle 20000
Redmond 30000
Select City, AVG(Salary) from Employee where ... I don't know the rest
Where city == city or something like that?
