Question

我们编写了一个存储过程，该过程使用SQL Server的send_dbmail功能向潜在用户发送电子邮件，并附上注册详情。

此存储过程效果很好。

我们目前唯一的问题是用户还希望索取他们忘记密码的副本。

我可以编写另一个存储过程来处理这个问题吗？但是，有没有办法修改下面的存储过程，以便它识别请求的模式？

例如，目前用户创建了一个帐户，帐户的详细信息存储在tblLogin表中。

此存储过程会抓取帐户信息，将其存储在通知表中，最后将此帐户的详细信息发送给刚刚注册的用户。

同样，我们希望在用户使用Forgotten Password功能来请求密码时处理相同的存储过程。

如何根据所请求的内容修改存储过程发送电子邮件？

换句话说，如果tblLogin表中存储的数据用于new account创建，则存储过程应该抓取它并向用户发送包含详细信息的电子邮件。

如果数据是forgotten password，则存储过程也应仅通过电子邮件发送该信息。

这可以使用下面的存储过程吗？

很抱歉，如果我在这里遗漏了一些内容，但看起来你只需要一个IF-ELSE语句，它将在一个案例中发送一条消息，另一条消息则另外发送消息......

如何修改存储过程以便它可以根据请求模式处理请求？
