我们编写了一个存储过程，它使用 SQL Server 的 send_dbmail 功能向潜在用户发送电子邮件，其中包含他们的注册详细信息。

这个存储过程很好用。

我们目前唯一的问题是用户还想索取一份他们忘记的密码的副本。

我可以写另一个存储过程来处理这个吗？但是，有没有办法修改下面的存储过程，使其识别请求的模式？

例如，当前用户创建了一个帐户，该帐户的详细信息存储在tblLogin表中。

此存储过程获取帐户信息，将其存储在 Notifications 表中，最后将该帐户的详细信息通过电子邮件发送给刚刚注册的用户。

Forgotten Password同样，当用户使用该功能请求密码时，我们希望处理相同的存储过程。

如何根据请求修改存储过程发送电子邮件？

换句话说，如果存储在tblLogin表中的数据用于new account创建，则存储过程应该获取它并向用户发送一封包含详细信息的电子邮件。

如果数据用于forgotten password，则存储过程也应该只通过电子邮件发送该信息。

这可以通过下面的存储过程实现吗？

抱歉，如果我在这里遗漏了一些东西，但这看起来你只需要一个 IF - ELSE 语句，它会在一种情况下发送一条消息，否则会发送另一条消息......</p>
