I have got two tables in Sql Server 2005:

  • USER Table: information about user and so on.
  • COUNTRY Table : Holds list of whole countries on the world.
  • USER_COUNTRY Table: Which matches, which user has visited which county. It holds, UserID and CountryID. For example, USER_COUNTRY table looks like this:

  • ID -- UserID -- CountryID

  • 1 -- 1 -- 34
  • 2 -- 1 -- 5
  • 3 -- 2 -- 17
  • 4 -- 2 -- 12
  • 5 -- 2 -- 21
  • 6 -- 3 -- 19

My question is that: When a user is deleted in USER table, how can I make associated records in USER_COUNTRY table deleted directly. Maybe, by using Foreign Key Constaint?
