For this challenge you need to create a simple SELECT statement that will return all columns from the people table WHERE their age is over 50

people table schema

  • id
  • name
  • age

You should return all people fields where their age is over 50 and order by the age descending

NOTE: Your solution should use pure SQL. Ruby is used within the test cases to do the actual testing.

 

 

Solution:

SELECT * FROM people WHERE age>50 ORDER BY age DESC
