最近遇到这样一个案例,需要修改所有SQL Server的Database Mail的SMTP,原来的SMTP为10.xxx.xxx.xxx, 现在需要修改为192.168.xxx.xxx, 另外需要规范邮件地址,以前这类邮件ServerName@yoursqldba.com的后缀需要修改为ServerName@xxxx.com(信息做了脱敏处理)。
如果使用SSMS客户端的UI界面去修改的话, 那么多服务器一台一台去修改,不仅费时费力,而且枯燥无聊。只能使用脚本,一旦写好一个脚本,而后使用Multiple Server Query Execution(极力推荐使用这个管理、维护数据库),执行一次脚本,全部搞定。剩下的时间你可以喝喝茶、学习下新知识!
DECLARE @EmailAccount sysname; DECLARE @SmtpServer sysname; DECLARE @EmailAddress NVARCHAR(120); DECLARE @EmailSuffix NVARCHAR(32); DECLARE @NewEamilAddress NVARCHAR(120); --DECLARE @ActualEmailSuffix NVARCHAR(32)='xxxx.com'; SQL Server 2005不支持此功能,会报Cannot assign a default value to a local variable. DECLARE @ActualEmailSuffix NVARCHAR(32); DECLARE @ActualSmtpServer sysname; SET @ActualEmailSuffix='xxx.com'; SET @ActualSmtpServer='192.168.xxx.xxx'; DECLARE EmailAccount_Cursor CURSOR FAST_FORWARD FOR SELECT sa.[name] ,ss.[servername] ,sa.email_address FROM [msdb].[dbo].[sysmail_server] ss INNER JOIN [msdb].[dbo].[sysmail_account] sa ON ss.[account_id]=sa.[account_id]; OPEN EmailAccount_Cursor; FETCH NEXT FROM EmailAccount_Cursor INTO @EmailAccount, @SmtpServer,@EmailAddress; WHILE @@FETCH_STATUS = 0 BEGIN IF LTRIM(RTRIM(@SmtpServer))!=@ActualSmtpServer BEGIN EXECUTE msdb.dbo.sysmail_update_account_sp @account_name = @EmailAccount ,@mailserver_name=@ActualSmtpServer; PRINT @SmtpServer; PRINT @EmailAccount; END; SET @EmailSuffix=SUBSTRING(@EmailAddress,CHARINDEX('@',@EmailAddress)+1, LEN(@EmailAddress) -CHARINDEX('@',@EmailAddress)) IF @EmailSuffix!=@ActualEmailSuffix BEGIN SET @NewEamilAddress= REPLACE(@EmailAddress,@EmailSuffix,@ActualEmailSuffix); EXECUTE msdb.dbo.sysmail_update_account_sp @account_name = @EmailAccount ,@email_address=@NewEamilAddress ,@mailserver_name=@SmtpServer; PRINT @EmailAccount; PRINT @NewEamilAddress; END; FETCH NEXT FROM EmailAccount_Cursor INTO @EmailAccount, @SmtpServer,@EmailAddress; END CLOSE EmailAccount_Cursor; DEALLOCATE EmailAccount_Cursor;
