script to show all the permissions for a table

I found a good script to see the permissions on a database object.

SELECT
  (
    dp.state_desc + ' ' +
    dp.permission_name collate latin1_general_cs_as + 
    ' ON ' + '[' + s.name + ']' + '.' + '[' + o.name + ']' +
    ' TO ' + '[' + dpr.name + ']'
  ) AS GRANT_STMT
FROM sys.database_permissions AS dp
  INNER JOIN sys.objects AS o ON dp.major_id=o.object_id
  INNER JOIN sys.schemas AS s ON o.schema_id = s.schema_id
  INNER JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id
WHERE 1=1
    AND o.name IN ('YOUR TABLE NAME')      -- Uncomment to filter to specific object(s)
--  AND dp.permission_name='EXECUTE'    -- Uncomment to filter to just the EXECUTEs
ORDER BY dpr.name

the script above works for a database object. however, when I add permissions on the schema where the db object is, the above script does not pick that up, for example:

grant delete on schema::dbo to [db_webUser] 
GO

so for that case I found this script here that caters for that as well:

SELECT
state_desc + ' ' + permission_name +
' on ['+ ss.name + '].[' + so.name + ']
to [' + sdpr.name + ']'
COLLATE LATIN1_General_CI_AS as [Permissions T-SQL]
FROM SYS.DATABASE_PERMISSIONS AS sdp
JOIN sys.objects AS so
     ON sdp.major_id = so.OBJECT_ID
JOIN SYS.SCHEMAS AS ss
     ON so.SCHEMA_ID = ss.SCHEMA_ID
JOIN SYS.DATABASE_PRINCIPALS AS sdpr
     ON sdp.grantee_principal_id = sdpr.principal_id
where 1=1
  AND so.name = 'ItemStock'

UNION

SELECT
state_desc + ' ' + permission_name +
' on Schema::['+ ss.name + ']
to [' + sdpr.name + ']'
COLLATE LATIN1_General_CI_AS as [Permissions T-SQL]
FROM SYS.DATABASE_PERMISSIONS AS sdp
JOIN SYS.SCHEMAS AS ss
     ON sdp.major_id = ss.SCHEMA_ID
     AND sdp.class_desc = 'Schema'
JOIN SYS.DATABASE_PRINCIPALS AS sdpr
     ON sdp.grantee_principal_id = sdpr.principal_id
where 1=1

order by [Permissions T-SQL]
GO

when I run the script above I get the following result, which includes the permission on the schema that reflects on my table.

I've got a couple of stored procedures you can use to display all of the permissions for a given database. Either for a single user/principal or for all of them. sp_dbpermissions and sp_srvpermissions.

The output for sp_dbpermissions (sp_srvpermissions is the same at a server level) looks like this

Off the page are revoke/grant/deny commands as appropriate.

FYI the example I have here was run using 'ALL' for the database parameter so it's displaying the output for all of the databases not just one.

I primarily intended them as research tools so you will find parameters that let you search out permissions directly applied to a given object (similar to your query above) or members of a given role (and the permissions for that role) etc.

Note: Minion also has an enterprise edition that does a lot of detailed data collection on permissions that might very well give you what you want. It is however a paid program. (If you can talk your management into the expense it's probably worth it)
