 ## Add a database to the availability group
 
-Ensure that the database you add to the availability group is in the full recovery model and has a valid log backup. If this is a test database or a newly created database, take a database backup. On the primary [!INCLUDE [ssnoversion-md](../../includes/ssnoversion-md.md)], run the following Transact-SQL script to create and back up a database called `db1`:

If your database is a test database or a newly created database, take a database backup. On the primary [!INCLUDE [ssnoversion-md](../../includes/ssnoversion-md.md)], run the following [!INCLUDE [tsql-md](../../includes/tsql-md.md)] (T-SQL) script to create and back up a database called `db1`:
 
 ```sql
 CREATE DATABASE [db1];
-ALTER DATABASE [db1] SET RECOVERY FULL;

 BACKUP DATABASE [db1]

 ### Verify that the database is created on the secondary servers
 
 On each secondary [!INCLUDE [ssnoversion-md](../../includes/ssnoversion-md.md)] replica, run the following query to see if the `db1` database was created and is synchronized:
 
 ```sql
-SELECT * FROM sys.databases WHERE name = 'db1';
+SELECT * FROM sys.databases
+WHERE name = 'db1';
+GO
+
+SELECT DB_NAME(database_id) AS 'database',
+    synchronization_state_desc
+FROM sys.dm_hadr_database_replica_states;
 GO
-SELECT DB_NAME(database_id) AS 'database', synchronization_state_desc FROM sys.dm_hadr_database_replica_states;
 ```
