How to perform a Linq2Sql query on the following dataset
- by Bas
I have the following tables:
Person(Id, FirstName, LastName)
{
(1, "John", "Doe"),
(2, "Peter", "Svendson")
(3, "Ola", "Hansen")
(4, "Mary", "Pettersen")
}
Sports(Id, Name)
{
(1, "Tennis")
(2, "Soccer")
(3, "Hockey")
}
SportsPerPerson(Id, PersonId, SportsId)
{
(1, 1, 1)
(2, 1, 3)
(3, 2, 2)
(4, 2, 3)
(5, 3, 2)
(6, 4, 1)
(7, 4, 2)
(8, 4, 3)
}
Looking at the tables, we can conclude the following facts:
John plays Tennis
John plays Hockey
Peter plays Soccer
Peter plays Hockey
Ola plays Soccer
Mary plays Tennis
Mary plays Soccer
Mary plays Hockey
Now I would like to create a Linq2Sql query which retrieves the following:
Get all Persons who play Hockey and Soccer
Executing the query should return: Peter and Mary
Anyone has any idea's on how to approach this in Linq2Sql?
