SQL Server發送郵件的存儲過程

對於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.

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

對於資料變更，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。

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。
