如何将参数分配给要作为输出通过电子邮件发送的查询？

Question

我正在尝试将查询结果作为电子邮件正文通过电子邮件发送。我正在使用 2 个存储过程来完成此操作。第一个存储过程是一个示例电子邮件代码，因为 SQL Server 2000 没有像 SQL Server 2005 和 SQL Server 2008 那样的内置发送邮件功能。

这是我目前对存储过程的了解：我声明@Body，然后将@Body 分配给运行以下查询的存储过程getpaidout1929 (Exec @Body = sp_getpaidout1929)。

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName
FROM            Paid_Out_Tb
WHERE        (Store_Id = 1929) AND (Paid_Out_Amount > 50) AND (Paid_Out_Datetime BETWEEN CONVERT(DATETIME, '2012-06-01 00:00:00', 102) AND CONVERT(DATETIME, 
                         '2012-06-30 00:00:00', 102)) 

然后我执行存储过程。

Exec sp_SQLNotify ‘to@who.com', ‘who@who.com, ‘test’

它发送电子邮件但有0作为正文消息。

Create PROCEDURE [dbo].[sp_SQLNotify] 
   @From varchar(100) ,
   @To varchar(100) ,
   @Subject varchar(100)=" "

您是否检查过syntax 以执行存储过程？如果你这样做：

exec @foo = dbo.SomeProc

然后@foo 包含过程的返回状态，在这种情况下为零表示成功。

SQL 2000 确实有built-in email，因此您可以将存储过程执行字符串作为@query 参数传递，以避免必须自己将结果集转换为标量值。

您还应该考虑使用 Perl、PowerShell 等语言的外部脚本，因为使用纯 TSQL 方法格式化和通过电子邮件发送数据既不简单也不灵活。
