Execute privilege at the database level

[Kyle Murphy]

I have created a user and assigned the Execute privilege at the DATABASE level.

When attempting to CALL any stored procedure under this database, I would expect the database-level Execute privilege to allow execution on this procedure. Instead, I am forced to give Execute privilege to each Stored Proc individually for it to work. This is a real pain.

What is the purpose of the Execute privilege at the DATABASE level? I would expect each stored procedure to inherit the database-level Execute privilege, thus preventing me to have to explicitly give Execute permissions at the stored proc level.
