Grant a user the select permission on a view that references external objects

Question

Hi all,
SQL Server 2012 Enterprise Edition SP2.
I've a database (let's say SRC_DB) that contains a series of views, some of these views refercenses tables or other views in other databases (let's say EXT_DB). I'm searching the best way to grant a user permission to SELECT from that view without granting
permission to every single obejct in external databases referenced by the view.

There is a dmv that tells you all the referenced views and tables. you can use that to get the list of all the tables,views being referenced in the cross database and them scrip the to grant only on those views\tables.
the link  is here:  https://msdn.microsoft.com/en-us/library/bb677315.aspx
example from the link that woulf work for your suitation:
CREATE DATABASE db1;
GO
USE db1;
GO
CREATE PROCEDURE p1 AS SELECT * FROM db2.s1.t1;
GO
CREATE PROCEDURE p2 AS
UPDATE db3..t3
SET c1 = c1 + 1;
GO
SELECT OBJECT_NAME (referencing_id),referenced_database_name,
referenced_schema_name, referenced_entity_name
FROM sys.sql_expression_dependencies
WHERE referenced_database_name IS NOT NULL;
GO
USE master;
GO
DROP DATABASE db1;
GO
Hope it Helps!!
