Join two tables based on relationship defined in third table

Question

I have two tables Activity and Action. One or more actions can be performed for an activity. And the relationships between Activity and Action is given in a third table call

Answer 1

SELECT ActivityText AS Activity, ActionText AS ApplicableAction
  FROM Activity 
  JOIN ActivityAction on Activity.ActivityId = ActivityAction.ActivityID
  JOIN Action on Action.ActionId = ActivityAction.ActionID

You have IDs in Action table and when you join table ActivityAction on ActivityId key then you are able to join activity table
