SQL Server :: How To Query Previous And Next Record

Id - Date - Type 1 - 2011-03-01 - 1 2 - 2011-03-02 - 0 3 - 2011-03-03 - 0 4 - 2011-03-04 - (-1) 5 - 2011-03-04 - 0
Can I somehow select the records between a record having type 1 and type -1 without using a cursor,for example the records with ids 1-4 in this example?
