Question

我编写了一个游标，用于从用户临时表中获取用户。然后它找出最新的事务（基于许多因素）并给出输出消息和其他结果。

我无法想到为某些集合中的每个用户存储这些值然后返回到前端的想法。这是我的代码。

declare @cur1_patientid uniqueidentifier
declare @cur1_dueid uniqueidentifier
declare @cur1_dueamount varchar(10)
declare @cur1_patientname varchar(50)
declare @cur1_paymentday varchar(2)
declare @cur1_monthlyamount varchar(10)
--transaction table variables start
declare @trans_id uniqueidentifier
declare @trans_date datetime
declare @trans_amount float
declare @trans_type varchar(45)
declare @trans_status varchar(45)
declare @trans_patVisitid uniqueidentifier
--transaction table variables end

--declare other variables that will be used - start
declare @output_ARB_Date datetime
declare @output_check_flag bit
declare @output_msg varchar(MAX)
declare @output_difference numeric(3)
--declare other variables that will be used - end
set @output_check_flag=0
set @output_msg=''
set @output_difference=0

declare arb_cur cursor FAST_FORWARD for
select PatientId,dueid,dueamount,patientname,paymentday,monthlyamount from #ARB_Report1 where patientId 
in ('D3658295-51B5-41DF-A1A4-E34B90EBD0F7','27F37F32-4984-47CC-B470-D086192D68FB')

open arb_cur
FETCH NEXT FROM arb_cur INTO @cur1_patientid,@cur1_dueid,@cur1_dueamount,@cur1_patientname,@cur1_paymentday,@cur1_monthlyamount

        WHILE @@FETCH_STATUS = 0        
        BEGIN
        --SELECT @cur1_patientid,@cur1_dueid --shows patientid,dueid of cursor1
            DECLARE trans_cur CURSOR  FOR 
                SELECT id,date,amount,type,status,patientVisitId FROM Transactions WHERE patientId=@cur1_patientid order by date desc
                open trans_cur
                    --fetch transaction table values in local variables
                    FETCH NEXT FROM trans_cur into @trans_id,@trans_date,@trans_amount,@trans_type,@trans_status,@trans_patVisitid                  
                    --reset the variables-start
                    set @output_check_flag=0
                    set @output_msg=''
                    set @output_difference=0
                    set @output_ARB_Date=null
                    --reset the variables-end
                    WHILE (@@FETCH_STATUS = 0)
                    begin

                    if(@trans_type='Reoccuring' and @trans_amount=@cur1_monthlyamount and @trans_patVisitid is null)
                            begin
                                if(@trans_status='Failed')
                                begin
                                    --// some code
                                end

                                else if(@trans_status='Success')
                                begin
                                    --// some code
                                end
                        select @cur1_patientid,@cur1_monthlyamount,@trans_amount,@output_ARB_Date,@output_msg,@output_difference,@cur1_dueamount
                        ------ SOME INSERT STATEMENT HERE TO STORE THESE VALUES INTO A COLLECTION FOR EVERY PATIENT------
                        break
                    end                                             

                    FETCH NEXT FROM trans_cur into @trans_id,@trans_date,@trans_amount,@trans_type,@trans_status,@trans_patVisitid                      
                    end
                CLOSE trans_cur
            DEALLOCATE trans_cur        
FETCH NEXT FROM arb_cur INTO @cur1_patientid,@cur1_dueid,@cur1_dueamount,@cur1_patientname,@cur1_paymentday,@cur1_monthlyamount
END 
CLOSE arb_cur
DEALLOCATE arb_cur
GO

在sql server中运行游标时存储多行
