Finding stored procedures having execute permission

Question

I am using SQL Server 2008 R2. I need to list out all the stored procedures that a database user (MYUSER) has execute permission.

Also, I need to list out which are the stored procedures that the user does NOT have EXECUTE permission - but can read the script of the stored procedure

Is there any SQL statement or helper function for these purpose?

REFERENCE:

1. Granting execute permission on all stored procedures in a certain database

Answer 1

Use HAS_PERMS_BY_NAME:

select name, 
    has_perms_by_name(name, 'OBJECT', 'EXECUTE') as has_execute,
    has_perms_by_name(name, 'OBJECT', 'VIEW DEFINITION') as has_view_definition
from sys.procedures

Answer 2

To check the permission for a different user, use this:

use my_db;
EXECUTE AS user = 'my_user'
SELECT SUSER_NAME(), USER_NAME();
select name, 
    has_perms_by_name(name, 'OBJECT', 'EXECUTE') as has_execute

from sys.procedures
where name = 'myprocname';
revert;

Works for my SQL Server 2012.
