Question

我已经编写了这段代码，以显示单个学生的费用支付，待定等，但实际上它应该适用于整个班级的学生。我尝试了很多，但不能为全班做这件事。这该怎么做？忽略@studentID，我只想要@ClassID。

ALTER PROCEDURE [Accounts].[GetUserPaymentsPartialRecord] 
    @StudentId INT= 14,
    @classID int=1 
AS
BEGIN



    declare @accID int
    set @accID= (select st.Account_ID from School.StudentInformation ST where st.StudentID = @StudentId and st.ClassToWhichAdmitted_ID= @classID)

    declare @className varchar(50)
    Set @className= (Select c.ClassName from School.Classes c 
                     Inner Join School.StudentInformation si 
                     ON si.ClassToWhichAdmitted_ID= c.ClassID where si.StudentID= @StudentId) 

    declare @transactions varchar(max)
    Set @transactions=(select convert(varchar,Convert(decimal(10,0),t.Credit))+', ' AS 'data()'  from Accounts.Transactions T 
    where t.Account_ID = (@accID)
    and
    t.Credit>0 
    AND 
    t.IsReversed=0
    AND 
    t.InvoiceNumber in(Select inv.InvoiceNumber from Accounts.Invoices inv where inv.Student_ID= @StudentId) 
    AND 
    Particulars Like '%Received%'
    FOR XML PATH(''))

    declare @PayableAmount money
    set @PayableAmount = (select sum(i.Amount+ i.Fine) from Accounts.Invoices I where I.Student_ID= @StudentId and i.Class_ID = @classID )              


    declare @TotalAmountPaid money
    Set @TotalAmountPaid= (Select sum(t.Credit) from Accounts.Transactions T 
    where t.Account_ID = (@accID)
    and
    t.Credit>0 
    AND 
    t.IsReversed=0 
    AND 
    t.InvoiceNumber in(Select inv.InvoiceNumber from Accounts.Invoices inv where inv.Student_ID= @StudentId) 
    AND 
    t.Particulars Like '%Received%'
    group by t.Account_ID)


    declare @PendingAmount money
    Set @PendingAmount= (@PayableAmount - @TotalAmountPaid)

    SELECT st.StudentName, st.StudentRegisterationNo,@className as ClassName, 
            @transactions as Paid, Convert(decimal(10,0),@TotalAmountPaid) as TotalPaid,
            @PayableAmount, @PendingAmount as 'PendingAmount' FROM School.StudentInformation ST 
    where st.StudentID= @StudentId



END

您可以尝试将上述程序（学生和班级）简单地移动到可以在班级查询的表格集

参见下面的示例程序：

<header></header> 
<div class="page-container">

<div class="left-column">left</div>
<div class="center-column">center</div>
<div class="right-column">right</div>

</div>
<footer></footer>

如何显示一组人的输出而不是一个人？
