最後の完全バックアップの日付、サイズ、場所のT-SQLクエリ

以下のT-SQLクエリを使用して、最後の完全データベースバックアップの日付を決定し、バックアップファイルのサイズと場所も返します。私の問題は、バックアップがなかった、またはバックアップ履歴がないデータベースのデータをまったく返さないことです。理想的には、バックアップ履歴があるかどうかに関係なく、すべてのデータベースが返されるようにクエリを変更したいと思います。以下のクエリを変更してこれに対応する方法を誰かにアドバイスできますか？

WITH LastBackUp AS
(
SELECT  bs.database_name,
        bs.backup_size,
        bs.backup_start_date,
        bmf.physical_device_name,
        Position = ROW_NUMBER() OVER( PARTITION BY bs.database_name ORDER BY bs.backup_start_date DESC )
FROM  msdb.dbo.backupmediafamily bmf
JOIN msdb.dbo.backupmediaset bms ON bmf.media_set_id = bms.media_set_id
JOIN msdb.dbo.backupset bs ON bms.media_set_id = bs.media_set_id
WHERE   bs.[type] = 'D'
AND bs.is_copy_only = 0
)
SELECT 
        database_name AS [Database],
        CAST(backup_size / 1048576 AS DECIMAL(10, 2) ) AS [BackupSizeMB],
        backup_start_date AS [Last Full DB Backup Date],
        physical_device_name AS [Backup File Location]
FROM LastBackUp
WHERE Position = 1
ORDER BY [Database];

最初にデータベースのリストをクエリする必要があります（sys.databasesにあります）。次にそれをクエリに結合します。

WITH LastBackUp AS
(
SELECT  bs.database_name,
        bs.backup_size,
        bs.backup_start_date,
        bmf.physical_device_name,
        Position = ROW_NUMBER() OVER( PARTITION BY bs.database_name ORDER BY bs.backup_start_date DESC )
FROM  msdb.dbo.backupmediafamily bmf
JOIN msdb.dbo.backupmediaset bms ON bmf.media_set_id = bms.media_set_id
JOIN msdb.dbo.backupset bs ON bms.media_set_id = bs.media_set_id
WHERE   bs.[type] = 'D'
AND bs.is_copy_only = 0
)
SELECT 
        sd.name AS [Database],
        CAST(backup_size / 1048576 AS DECIMAL(10, 2) ) AS [BackupSizeMB],
        backup_start_date AS [Last Full DB Backup Date],
        physical_device_name AS [Backup File Location]
FROM sys.databases AS sd
LEFT JOIN LastBackUp AS lb
    ON sd.name = lb.database_name
    AND Position = 1
ORDER BY [Database];

複数のファイルにバックアップするとどうなりますか？このスクリプトはそれをすべて表示します。
