如何从 sp_MSforeachdb 中排除 tempdb？

Question

下面我有一个代码来获取有关服务器中每个数据库的 t-log 备份的信息。我想从这个列表中排除 tempdb。

exec sp_MSforeachdb 'SELECT server_name, sysdb.name AS DatabaseName, bkup.user_name AS [User],
ceiling(bkup.backup_size /1048576) as ''Size Meg'' ,
cast((bkup.backup_size /1073741824) as decimal (9,2)) as ''Gig'',
bkup.backup_start_date AS [Backup Started],
bkup.backup_finish_date AS [Backup Finished (Last BackUp Time)],
CAST((CAST(DATEDIFF(s, bkup.backup_start_date, bkup.backup_finish_date) AS int))/3600 AS varchar) + '' hours, ''
+ CAST(DATEDIFF(mi, bkup.backup_start_date, bkup.backup_finish_date) - (DATEDIFF(mi, bkup.backup_start_date, bkup.backup_finish_date)/60)*60 AS varchar) + '' minutes, ''
+ CAST((CAST(DATEDIFF(s, bkup.backup_start_date, bkup.backup_finish_date) AS int))%60 AS varchar)+ '' seconds'' AS [Total Time]
,DATEDIFF(DAY,CONVERT(CHAR(8),backup_finish_date,112),CONVERT(CHAR(8),expiration_date,112)) AS expiration_days
,bms.description AS [Description]
,bkup.is_damaged AS isDamaged
,bms.is_compressed AS isCompressed
,bkup.is_copy_only AS isCopyOnly
,bkup.database_creation_date AS DatabaseCreationDate
,bmf.physical_device_name AS PhysicalDeviceName
,CASE WHEN (bkup.backup_start_date is NULL OR bkup.backup_start_date < DATEADD(dd,-1,GetDate()) ) THEN ''Yes'' ELSE ''No'' END AS isOlderThan24Hours
,bkup.database_backup_lsn
,bkup.differential_base_lsn
,bkup.first_lsn
,bkup.last_lsn
,bkup.fork_point_lsn
FROM master.dbo.sysdatabases sysdb
LEFT OUTER JOIN msdb.dbo.backupset bkup ON bkup.database_name = sysdb.name
INNER JOIN msdb.dbo.backupmediafamily AS bmf ON bkup.media_set_id = bmf.media_set_id
LEFT outer JOIN sys.backup_devices AS bd ON bmf.device_type = bd.type
LEFT outer JOIN msdb.dbo.backupmediaset AS bms ON bkup.media_set_id = bms.media_set_id
--WHERE backup_finish_date = (SELECT MAX(bkup.backup_finish_date) FROM  msdb.dbo.backupset bkup WHERE sysdb.name = bkup.database_name) --Last backup
WHERE backup_finish_date > DATEADD(DAY, -1, (getdate()))  -- Last 60 days
AND bkup.type=''L''
AND sysdb.name = ''?''
ORDER BY backup_start_date DESC, backup_finish_date';

我尝试编写 'IF ''?'' NOT IN (''tempdb'') SELECT ......'，但只有一个数据库的所有结果都相同。然后我尝试编写 AND sysdb.name <> ''tempdb'''' 但它给出了一个错误：

一种可能性是检查 DB_Name = 'Tempdb'，如果是 tempdb，则结束脚本。

这是我做的一个快速测试，它似乎有效：

EXEC sp_msforeachdb 'USE [?] IF DB_Name() = ''Tempdb''BEGIN RETURN END SELECT db_Name()'

这将在每个 db 上运行代码，但如果它是 tempdb，它不会执行任何事情，因为它会返回。

众所周知，使用 sp_msforeachdb 并不总是最好的。Aaron 已经在博客中介绍了使用您可以使用的自制更换程序，您可能值得花时间去检查一下！打造更可靠和灵活的 spmsforeachdb
