"Contains one row per database in the instance of Microsoft SQL Server."
select * from sys.databases;
If the caller of sys.databases is not the owner of the database and the database is not master
or tempdb, the minimum permissions required to see the corresponding row are
ALTER ANY DATABASE or VIEW ANY DATABASE server-level permission,
or CREATE DATABASE permission in the master database. If a database is not ONLINE
or AUTO_CLOSE is set to ON, the values of some columns may be NULL. If a database is
OFFLINE, the corresponding row is not visible to low-privileged users.
To see the corresponding row if the database is OFFLINE, a user must have at least the
ALTER ANY DATABASE server-level permission or the CREATE DATABASE permission
in the master database.
