Querying SQL Views

 If you create a view such as
  CREATE VIEW TestView

AS Select * FROM customers_table WHERE CustomerID between 213 AND 3443 

 
Each time you want to select from the view - is the View going to perform the WHERE clause on the customers_table, or not?
Or does the view already have the virtual rows?, meaning it does not have to perform a where clause  (WHERE CustomerID between 213 AND 3443) on the customers_table, and just performs an inner join with the rows it already has?
