如何利用SQL Server来发送电子发邮件？

在SQL Server中，提供了通过Exchange或Outlook收发邮件的扩展存储过程。

下面简单地介绍一下：

一、启动SQL Mail：

xp_startmail @user,@password
其中，@user和@password都是可选的。
     也可打开Enterprise Manager中的Support Services，在SQL Mail上单击右键打开右键菜单，然后按Start来启动

二、停止SQL Mail
    xp_stopmail
    也可用上述方法中的菜单里的Stop来停止

三、发送邮件
    xp_sendmail {[@recipients =] 'recipients [;...n]'}
        [,[@message =] 'message']
        [,[@query =] 'query']
        [,[@attachments =] attachments]
        [,[@copy_recipients =] 'copy_recipients [;...n]'
        [,[@blind_copy_recipients =] 'blind_copy_recipients [;...n]'
        [,[@subject =] 'subject']
        [,[@type =] 'type']
        [,[@attach_results =] 'attach_value']
        [,[@no_output =] 'output_value']
        [,[@no_header =] 'header_value']
        [,[@width =] width]
        [,[@separator =] 'separator']
        [,[@echo_error =] 'echo_value']
        [,[@set_user =] 'user']
        [,[@dbuse =] 'database']

 参数说明：

四、阅读邮件收件箱中的邮件
    xp_readmail [[@msg_id =] 'message_number'] [, [@type =] 'type' [OUTPUT]]
        [,[@peek =] 'peek']
        [,[@suppress_attach =] 'suppress_attach']
        [,[@originator =] 'sender' OUTPUT]
        [,[@subject =] 'subject' OUTPUT]
        [,[@message =] 'message' OUTPUT]
        [,[@recipients =] 'recipients [;...n]' OUTPUT]
        [,[@cc_list =] 'copy_recipients [;...n]' OUTPUT]
        [,[@bcc_list =] 'blind_copy_recipients [;...n]' OUTPUT]
        [,[@date_received =] 'date' OUTPUT]
        [,[@unread =] 'unread_value' OUTPUT]
        [,[@attachments =] 'attachments [;...n]' OUTPUT]]
        [,[@skip_bytes =] bytes_to_skip OUTPUT]
        [,[@msg_length =] length_in_bytes OUTPUT]
        [,[@originator_address =] 'sender_address' OUTPUT]]

    参数说明：

五、处理下一个邮件：
    xp_findnextmsg [[@msg_id =] 'message_number' [OUTPUT]]
        [,[@type =] type]
        [,[@unread_only =] 'unread_value']]

六、删除邮件：
    xp_deletemail {'message_number'}
    如果不指定邮件编号则删除收件箱中的所有邮件

七、自动处理邮件：
    sp_processmail [[@subject =] 'subject']
        [,[@filetype =] 'filetype']
        [,[@separator =] 'separator']
        [,[@set_user =] 'user']
        [,[@dbuse =] 'dbname']
