Opis
The cross db ownership chaining option controls cross-database ownership chaining across all databases at the instance (or server) level. Both value and value_in_use must equal 0. Default: By default, this option is disabled (0). 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.
