Запрос ссылок на хранимую процедуру в MS SQL Server

Мне нужно найти ссылки на все хранимые процедуры в недокументированной базе данных. Некоторые ссылки не работают, поэтому что-то вроде ниже будет выдавать ошибки 

SELECT 
    DB_NAME()       AS REFERENCING_DB,
    t.SCHEMA_NAME   AS REFERENCING_SCHEMA,
    t.OBJECT_NAME   AS REFERENCING_OBJECT,
    t.type_desc     AS REFERENCING_TYPE_DESC,
    --,'' AS SEPERATOR1
    CASE 
       WHEN ISNULL(ref.referenced_database_name, DB_NAME()) = '' 
          THEN '?' 
          ELSE ISNULL(ref.referenced_database_name, DB_NAME()) 
    END AS [REFERENCED_DB],
    ref.referenced_schema_name  AS REFERENCED_SCHEMA,
    ref.referenced_entity_name  AS REFERENCED_OBJECT,
    ref.referenced_minor_name   AS REFERENCED_MINOR_OBJECT,
    obj.type_desc               AS REFERENCED_TYPE_DESC,
    ref.referenced_class_desc   AS REFERENCED_CLASS_DESC,
    ref.is_caller_dependent     AS REFERENCED_IS_CALLER_DEPENDENT
FROM 
    (SELECT 
         o.name AS OBJECT_NAME, o.TYPE_DESC, s.name AS SCHEMA_NAME
     FROM
         sys.objects o
     LEFT JOIN 
         sys.schemas s on o.schema_id = s.schema_id
    ) t 
CROSS APPLY 
    sys.dm_sql_referenced_entities('[' + t.SCHEMA_NAME + '].[' + t.OBJECT_NAME + ']', 'OBJECT') ref
LEFT JOIN 
    sys.objects obj ON ref.referenced_id = obj.object_id

Ошибка:

Сообщение 942, Уровень 14, Состояние 4, Строка 231
База данных «BlahBlahBlah» не может быть открыта, потому что она находится в автономном режиме.

Любая помощь в решении этой проблемы или идеи по инструментам для поиска зависимостей в SQL Server было бы полезно знать!
