遊標提取聲明，呼籲第一行repetedly

Question

嗨，

我創建了簡單的SELECT語句的遊標它只有10行 當我去後打印，而@@ FETCH_STATUS = 0，那麼它遞歸調用 僅第一行，執行沒有停止。 我不知道爲什麼越來越只顯示第一行repetedly光標不移動到第二行

Here below is my code 

    declare cur_data cursor for 

select DISTINCT pkd.boxnumber from packagedetail pkd 
inner join PalletDetail pld on pld.boxnumber=pkd.boxnumber 
INNER JOIN TRACKING T ON T.BOXNUM=PKD.SCANBOXID 
where pkd.shipmentlocation='NYWH' AND pld.shipmentnumber='SH0675535' 

declare @boxnumber NVARCHAR(50) 

open cur_data 

fetch next from cur_data into @boxnumber 
while @@fetch_status=0 
begin 

print @boxnumber 

END 
close cur_data 
deallocate cur_data

你必須有一個取...下一while循環也在裏面......

... 
open cur_data 
fetch next from cur_data into @boxnumber 
while @@fetch_status=0 
BEGIN 
    print @boxnumber 
    fetch next from cur_data into @boxnumber 
END 
...
