发送电子邮件到特定的细分和框架

Question

我有两个数据库表，电子邮件和设备。

Email(User will subscribe and select what segment and framework they want)
=====
ID , EMAIL, NAME , SEGMENT ,FRAMEWORK

Equipment(equipment name with all details)
=========
EQUIPMENT ID , COM_STATE , SEGMENT ,FRAMEWORK

有许多segment和framework值：如何向特定segment和framework发送电子邮件？

mail.To.Add(emailnam); #email to send  
mail.Body = (emailboyd); #email equipmentid with particular segment and framework  

很难解释。我尝试连接表，但很难将一个电子邮件与许多设备ID合并。

Answer 1

你可以使用if for email然后收集所有信息。这应该很容易 从数据库查询然后检查

if(email=='')
{
  if (segment='')
 {  }
}
