嵌套循环游标

Question

我有这个SP它假设通过传递UserIDs和SectionIDs为学生添加部分ID 它工作正常，但我需要做的是修改它以给出结果

--split function return table contain 2 columns ID and vItem
ALTER PROC [dbo].[StudentDistribution] --'1,3,16,17,18,19','1,2,3',1,1   
(
@pUserID varchar(8000),
@pSectionID varchar(8000),
@pClassID int,
@pModifiedBy int    
)
as

DECLARE @vCntr int  
DECLARE @vSectionCounter int
DECLARE @vCapacity int 
DECLARE @vCurrentStudent int
DECLARE @vCurrentCapacity int

SET @vSectionCounter = (select count(vItem) from split(@pSectionID,','))
SET @vCntr = (select count(*) from split(@pUserID ,','))
SET  @vCapacity = (select sum(Capacity) from SectionsClasses where ClassID=@pClassID and SectionID in (select vItem from split(@pSectionID,',')))
SET @vCurrentStudent = (select sum(CurrentNumber) from SectionsClasses where ClassID=@pClassID and SectionID in (select vItem from split(@pSectionID,',')))

SET @vCurrentCapacity=@vCapacity-@vCurrentStudent


    IF  EXISTS (SELECT 'true' from SectionsClasses where ClassID!=@pClassID and SectionID in (select vItem from split(@pSectionID,',')))
    BEGIN
        IF @vCntr >  @vCurrentCapacity
        BEGIN
            print('Operation cannot complete; the number of student exceeds capacity')
            return
        END
    END


DECLARE FetchStudent Cursor  SCROLL for
select vItem ,rank() OVER (order by FirstName )AS Sorted from split(@pUserID,',') INNER JOIN Users ON UserID=vItem

DECLARE @vUserID  int
DECLARE @vSecID int
DECLARE @vUI int
--Used to CHECK Capacity



        --BEGIN TRAN
        Open FetchStudent
        Fetch NEXT From FetchStudent into @vUserID,@vUI
        WHILE  @@FETCH_STATUS = 0
        BEGIN 
            --Section Cursor
            DECLARE FetchSection Cursor  SCROLL for
            select vItem 
            from split(@pSectionID,',') 
            INNER JOIN SectionsClasses ON SectionsClasses.ClassID=@pClassID AND SectionsClasses.SectionID=vItem
                        WHERE CurrentNumber < Capacity

                OPEN FetchSection
                    Fetch NEXT From FetchSection into @vSecID
                    WHILE @@FETCH_STATUS = 0
                    BEGIN

                    print('#####')
                    PRINT(@vUserID)
                    PRINT(@vSecID)
                    PRINT('userID is ' + cast(@vUI as varchar ))
                    print('#####')

                    --Increase current numer of student in section by 1
                    UPDATE SectionsClasses SET CurrentNumber = CurrentNumber+1
                    WHERE SectionID=@vSecID and ClassID=@pClassID

                    Fetch NEXT From FetchSection into @vSecID
                    break
                    END
                    Close FetchSection
                    Deallocate FetchSection
        Fetch NEXT From FetchStudent into @vUserID,@vUI
        END

我需要修改它才能给我这个结果

如果我传递@ pUserID ='1,2,3,4'和@ pSectionID ='1,2'

然后结果是 1 1 2 2 3 1 4 2 。 。

任何人都可以帮忙吗？
