Well both of them aren't even compatible to compare and 
tell the difference. They both belong to different paradigm 
of database world. Anyways, here are the definitions I 
would give you. A stored procedure is a set of sql 
statements which can be called a subroutine to access 
relational database systems. Its actually stored in a 
daatabase. They are mainly used for faster access(Pre-
compilation of SQL statements) ,Simplification of data 
management and for security.

A view as my friends have elucidated above is a virtual or 
logical table that holds result set of a pre-defined query. 
The data for these views are not stored in the database. 
There are two types of view read only and updatable. You 
can modify a read only view with an INSTEAD OF trigger.

Hope that makes sense :-)

both can never be compares, as both have totally different
approached,

Well a view is a output of a query ,and makes a virtual
image of the table,and the input parameters are not accepted.

sp is a group of sql statements that are pre-executed and it
accepts the parameters.it reduces network traffic, gives
faster performance, etc.

views & stored procedure are basically different appraches.
both have their different purposes.
 view is  a virtual table. which have no data atall.which 
difination stored in oracle system catalogue . whenever  a 
call is made  every time the defination is scanned & a new 
virtual table is made over the base table.
  while stored procedure are the precompiled statements 
which can accept arguments..
