SQL Server备份报告

Question

我正在尝试创建一个报告，其中详细介绍了我们SQL Server上的最新备份。 截至目前，我已将其写出：

select 
    [Server_Name] = a.server_name, 
    [Database_Name] = a.database_name, 
    [Last_Backup] = max(a.backup_finish_date),  
    [Backup_Type] = CASE A.type
                              WHEN 'D' THEN 'FULL'
                              WHEN 'I' THEN 'Differential'
                              WHEN 'L' THEN 'Log'
                              WHEN 'F' THEN 'FileGroup'
                              WHEN 'G' THEN 'FileGroup Differential'
                              WHEN 'P' THEN 'Partial'
                              WHEN 'Q' THEN 'Partial Differential'
                  END,
    [Backup_Set] = b.name,
    [Days_Since_Last_Backup] = DATEDIFF(d,(max(a.backup_finish_Date)),GETDATE())
from msdb.dbo.backupset AS a
INNER JOIN msdb.dbo.backupset as b ON a.backup_set_id = b.backup_set_id
GROUP BY a.database_name, a.server_name, b.name, a.type
ORDER BY database_name

我想更改它，以便列显示以下内容：

Server_Name, Database_Name, Last_Full_Backup, Last_Diff_Backup, Last_Log_Backup, 
Backup_Set, Days_Since_Last_Full

为了显示Last_Full_Backup ， Last_Diff_Backup和Last_Log_Backup的日期，我认为我必须进行一些Last_Log_Backup ，但是我不确定如何操作（我对旋转不十分熟悉）。

任何帮助将不胜感激。 在此先感谢所有。

您可以做一个“手动枢纽”，例如：

SELECT 
    [Server_Name] = a.server_name, 
    [Database_Name] = a.database_name, 
    [Last_Backup]      = MAX(a.backup_finish_date),  
    [Last_Full_Backup] = MAX(CASE WHEN A.type='D' 
                                    THEN a.backup_finish_date ELSE NULL END),
    [Last_Diff_Backup] = MAX(CASE WHEN A.type='I' 
                                    THEN a.backup_finish_date ELSE NULL END),
    [Last_Log_Backup]  = MAX(CASE WHEN A.type='L' 
                                    THEN a.backup_finish_date ELSE NULL END),
    [Backup_Set] = b.name,
    [Days_Since_Last_Backup] = DATEDIFF(d,(max(a.backup_finish_Date)),GETDATE())
FROM msdb.dbo.backupset AS a
INNER JOIN msdb.dbo.backupset as b ON a.backup_set_id = b.backup_set_id
GROUP BY a.database_name, a.server_name
ORDER BY database_name
