        WHEN 'OBJECT_OR_COLUMN'
            THEN CASE 
                    WHEN minor_id = 0
                        THEN'['+OBJECT_SCHEMA_NAME(major_id) + '].' + '[' + object_name(major_id) + ']' COLLATE Latin1_General_CI_AS_KS_WS
                    ELSE (
                            SELECT object_name(object_id) + ' (' + NAME + ')'
                            FROM sys.columns
                            WHERE object_id = database_permissions.major_id
                                AND column_id = database_permissions.minor_id
                            )
                    END
        ELSE 'other'
        END + ' TO [' + database_principals.NAME + ']' COLLATE Latin1_General_CI_AS_KS_WS

WHERE database_permissions.major_id > 0
    AND permission_name IN (
        'SELECT'
        ,'INSERT'
        ,'UPDATE'
        ,'DELETE'
        ,'EXECUTE'
