If a database is not ONLINE, or AUTO_CLOSE is set to ON and the database is closed, 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.
Columns that are relevant to Active Geo-Replication for SQL Database: is_ready_only, state, and state_desc.

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. The database to which the caller is connected can always be viewed in sys.databases.
By default, the public role has the VIEW ANY DATABASE permission, allowing all logins to see database information. To block a login from the ability to detect a database, REVOKE the VIEW ANY DATABASE permission from public, or DENY the VIEW ANY DATABASE permission for individual logins.
In SQL Database, this view is available in the master database and in user databases. In the master database, this view returns the information on the master database and all user databases on the server. In a user database, this view returns information only on the current database and the master database.
Use the sys.databases view in the master database of the SQL Database server where the new database is being created. After the database copy starts, you can query the sys.databases and the sys.dm_database_copies views from the master database of the destination server to retrieve more information about the copying progress.
The following example returns a few of the columns available in the sys.databases view.
SELECT name, user_access_desc, is_read_only, state_desc, recovery_model_desc FROM sys.databases;
The following example queries the sys.databases and sys.dm_database_copies views to return information about a database copy operation.
Applies to: Azure SQL Database
