Если процедура зашифрована…MsSql

Оставлю здесь код, который поможет разобраться с этой маленькой неприятностью…

надо помнить, чтобы этот скрипт сработал нужен режим администратора,а для этого
EXEC sys.sp_configure ‘show advanced options’, 1
RECONFIGURE WITH OVERRIDE
GO
EXEC sys.sp_configure ‘remote admin connections’, 1
RECONFIGURE WITH OVERRIDE
GO

—Вначале соединения в SQL документе дописываем ADMIN: и проверяем что пользователь под которым мы коннектимся является sysadmin-ом
—при подключении через DAC становится возможным выборка из любой системной таблицы и из нее

И наконец запускаем скрипт:

-- Must connect to SQL Server using the Dedicate Admin Connection, eg "admin:localhost". Verified with SQL Server 2012.
