Apakah ada kueri T-SQL yang menunjukkan datetime pemulihan terakhir untuk database tertentu?
Apakah ada kueri T-SQL yang menunjukkan datetime pemulihan terakhir untuk database tertentu?
Jawaban:
Ini akan mencantumkan semua pemulihan "terbaru" untuk setiap basis data di server Anda:
WITH LastRestores AS
(
SELECT
DatabaseName = [d].[name] ,
[d].[create_date] ,
[d].[compatibility_level] ,
[d].[collation_name] ,
r.*,
RowNum = ROW_NUMBER() OVER (PARTITION BY d.Name ORDER BY r.[restore_date] DESC)
FROM master.sys.databases d
LEFT OUTER JOIN msdb.dbo.[restorehistory] r ON r.[destination_database_name] = d.Name
)
SELECT *
FROM [LastRestores]
WHERE [RowNum] = 1
restorehistory
dapat dibersihkan oleh sp_delete_backuphistory
.
Script yang dapat digunakan adalah:
declare @DB sysname = 'MyDB';
select * from msdb.dbo.restorehistory where destination_database_name = @DB;
tabel utama untuk tujuan ini adalah msdb..restorehistory
SELECT [rs].[destination_database_name] ,
[rs].[restore_date] ,
[bs].[backup_start_date] ,
[bs].[backup_finish_date] ,
[bs].[database_name] AS [source_database_name] ,
[bmf].[physical_device_name] AS [backup_file_used_for_restore]
FROM msdb..restorehistory rs
INNER JOIN msdb..backupset bs ON [rs].[backup_set_id] = [bs].[backup_set_id]
INNER JOIN msdb..backupmediafamily bmf ON [bs].[media_set_id] = [bmf].[media_set_id]
ORDER BY [rs].[restore_date] DESC
Ini akan memberi Anda tanggal refresh terbaru untuk DB Anda:
use [msdb]
select top 1 * from restorehistory
where destination_database_name='DB_NAME'
order by restore_history_id desc
Menambahkan informasi penting tentang Nama Pengguna OS dan Nama Mesin:
Select Destination_database_name,
restore_date,
database_name as Source_database,
Physical_device_name as Backup_file_used_to_restore,
bs.user_name,
bs.machine_name
from msdb.dbo.restorehistory rh
inner join msdb.dbo.backupset bs
on rh.backup_set_id=bs.backup_set_id
inner join msdb.dbo.backupmediafamily bmf
on bs.media_set_id =bmf.media_set_id
ORDER BY [rh].[restore_date] DESC
Apakah ada kueri T-SQL yang menunjukkan datetime pemulihan terakhir untuk database tertentu?
Hai, saya telah membuat skrip di bawah ini yang dapat memberi Anda informasi lebih rinci tentang kueri Anda.
Permintaan untuk mendapatkan informasi "Pemulihan Terbaru" tentang database spesifik:
