SQL Server發送郵件的存儲過程
對于DB中的資料變更,有時會有寄Mail通知相關人員的需求。下面是實現這一功能的一種方法
1.建立發Mail的存儲過程
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.調用存儲過程
對于數據變更,可再Trigger中調用這一存儲過程。也可以在SQL Server Agent中建立作業來調用,只需要傳入相應參數即可。
exec sp_send_mail '發件者Email(采用存儲過程中寫入的那個Email)','收件者列表,各Email用分號隔開','主題','內容'
注:以上存儲過程有個缺陷,即@Body定義為varchar類型,而SQL Server中varchar類型長度最大是8000。也就是說一次最多只能發送8000個字符的內容。
