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.
This is one of the question asked by my friend and it seems very simple. I had a discussion with him and said that whatever the transaction it has started it will succeeded, however what I told him is not correct. I told him I’ll test it out and the answer which I gave it to him is partially correct. If the transaction gets completed with in begin tran (before commit or rollback) you can close the transaction even if the permission is revoked however if the transaction is not completed within begin tran then it will fail stating that the user don’t have access.
