SQL Server发送邮件的存储过程
对于DB中的资料变更，有时会有寄Mail通知相关人员的需求。下面是实现这一功能的一种方法
1.建立发Mail的存储过程
CREATE PROCEDURE [dbo].[sp_send_mail]
@From varchar(100) ,
@To varchar(2000) ,
@Subject varchar(2000)=" ",
@Body varchar(4000) =" ",
@BCC varchar(4000) =" "
/******************************************
This stored procedure takes the parameters and sends an e-mail. All the mail configurations are hard-coded in the stored procedure. Comments are added to the stored procedure where necessary. References to the CDOSYS objects are at the following MSDN Web site: http://msdn.microsoft.com/library/default.asp?url=/ library/en-us/cdosys/html/_cdosys_messaging.asp
*******************************************/
AS Declare @iMsg int
Declare @hr int
Declare @source varchar(255)
Declare @description varchar(500)
Declare @output varchar(2000)
--***** Create the CDO.Message Object *****
EXEC @hr = sp_OACreate 'CDO.Message', @iMsg OUT
--*****Configuring the Message Object *****
-- This is to configure a remote SMTP server.
-- Replace MailServerName by the name or IP of your SMTP Server.
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/smtpserver").Value', 'xxxserver'
-- http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdosys/html/_cdosys_schema_configuration_sendusing.asp
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/smtpserverport").Value','25'
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate").Value','1'
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/sendusing").Value','2'
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/smtpaccountname").Value','admin@xxx.com'
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/sendusername").Value','admin@xxx.com'
EXEC @hr = sp_OASetProperty @iMsg, 'Configuration.fields ("http://schemas.microsoft.com/cdo/configuration/sendpassword").Value','admin123'
-- This is to configure the Server Name or IP address.
-- Save the configurations to the message object.
EXEC @hr = sp_OAMethod @iMsg, 'Configuration.Fields.Update', null
-- Set the e-mail parameters.
EXEC @hr = sp_OASetProperty @iMsg, 'To', @To
EXEC @hr = sp_OASetProperty @iMsg, 'From', @From
EXEC @hr = sp_OASetProperty @iMsg, 'Subject', @Subject
EXEC @hr = sp_OASetProperty @iMsg, 'Bcc', @Bcc
-- If you are using HTML e-mail, use 'HTMLBody' instead of 'TextBody'.
EXEC @hr = sp_OASetProperty @iMsg, 'HTMLbody', @Body
--EXEC @hr = sp_OASetProperty @iMsg, 'TextBody', @Body
EXEC @hr = sp_OAMethod @iMsg, 'Send', NULL
-- Sample error handling.
IF @hr <>0
select @hr
BEGIN
EXEC @hr = sp_OAGetErrorInfo NULL, @source OUT, @description OUT
IF @hr = 0
BEGIN
SELECT @output = ' Source: ' + @source
PRINT @output
SELECT @output = ' Description: ' + @description
PRINT @output
END
ELSE
BEGIN
PRINT ' sp_OAGetErrorInfo failed.'
RETURN
END
END
-- Do some error handling after each step if you have to.
-- Clean up the objects created.
EXEC @hr = sp_OADestroy @iMsg
2.调用存储过程
对于数据变更，可再Trigger中调用这一存储过程。也可以在SQL Server Agent中建立作业来调用，只需要传入相应参数即可。
exec sp_send_mail '发件者Email(采用存储过程中写入的那个Email)','收件者列表，各Email用分号隔开','主题','内容'
注：以上存储过程有个缺陷，即@Body定义为varchar类型，而SQL Server中varchar类型长度最大是8000。也就是说一次最多只能发送8000个字符的内容。
