Ensure 'Trustworthy' Database Property is set to 'Off'

AltaNivel 1Automatizadamssql

Descripción

The TRUSTWORTHY database option allows database objects to access objects in other databases under certain circumstances. Default: By default, this database property is OFF (is_trustworthy_on = 0), except for the msdb database in which it is required to be ON. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.
