In the DBA world it’s necessary to pickup permissions for an object for all objects when he\she deploys the code. During deployment if the code has DROP and CREATE then it’s obvious that what ever permission you have assigned to that object will get lost so as a first step you need to script out permissions for the objects. You can get similar information using sp_helprotect procedure but you need to manually write the grant script from the output and you can’t use it for multiple or all objects. This is where I felt to write a script which can fetch all the permission related information for an object or for all the objects using sys.database_permissions dmv.
