许多内部联接（SQL Server）具有更好的性能

Question

我有一个SQL Server存储过程，其中包含许多对程序功能很重要的内部联接，但它们会影响性能。

有没有其他方法可以替换连接并提高性能？

代码：

 SELECT distinct (Account.first_name + ' ' + Account.last_name) as StudentName
    FROM Account INNER JOIN  Student_Disconnection
    ON  Student_Disconnection.session_id =Account.session_id
     and Student_Disconnection.account=Account.account
    WHERE Student_Disconnection.session_id= @SessionID
    and  isnull(Student_Disconnection.account_Read,0)!=1
    End
