2. Query to Identify when the Stored Procedure was last run
   SELECT b.name, a.last_execution_time
    FROM  sys.dm_exec_procedure_stats a
    INNER  JOIN sys.objects b ON a.object_id = b.object_id
    WHERE  Db_name(a.database_id) = 'Databasename'
    ORDER  BY a.last_execution_time DESC

3. Query to Identify user permissions
CREATE PROC [dbo].[usp_DBA_List_User_Role_Permissions]

@database nvarchar(128)=null,
@user varchar(20)=null,
@dbo char(1)=null,

@datawriter char(1)=null,
@denyread char(1)=null,
@denywrite char(1)=null
)

declare @dbname varchar(200)
declare @mSql1 varchar(8000)
