甲骨文PLSQL BULK收集並For循環

Question

我已經寫以下Oracle過程批量來獲取數據和在塊處理它。我正在使用有限的批量收集選項來獲取數據。但是在for循環中，我無法檢索ORD_ID。我試圖輸出使用

DBMS_OUTPUT.put_line(l_orders(indx)); 

但是，讓編譯錯誤「的論點錯號碼或類型調用‘PUT_LINE’」

create or replace PROCEDURE TESTPROC AS 

CURSOR order_id_cur IS SELECT ORD_ID FROM orders ORDER BY ORD_ID ASC; 
l_order_id VARCHAR2(100); 
TYPE orders_aat IS TABLE OF order_id_cur%ROWTYPE; 
l_orders orders_aat; 
limit_in NUMBER  :=10; 
batch_in NUMBER :=0; 


BEGIN 
    OPEN order_id_cur; 
    LOOP 
    FETCH order_id_cur 
     BULK COLLECT INTO l_orders LIMIT limit_in; 
    DBMS_OUTPUT.put_line('Batch-----'||batch_in); 
    FOR indx IN 1 .. l_orders.COUNT 
    LOOP 
     DBMS_OUTPUT.put_line(indx); 
     DBMS_OUTPUT.put_line(l_orders(indx)); 
    END LOOP; 

    EXIT WHEN l_orders.COUNT < limit_in; 
    batch_in := batch_in+1; 
    END LOOP; 
    CLOSE order_id_cur; 
END TESTPROC; 

如何才能得到裏面的ORD_ID的值ORD_ID for循環。

Answer 1

做這樣的 -

DBMS_OUTPUT.put_line(l_orders(indx).ORD_ID);

例如，

SQL> DECLARE 
    2 type t 
    3 IS 
    4 TABLE OF emp%rowtype; 
    5 a t; 
    6 BEGIN 
    7 SELECT * BULK COLLECT INTO a FROM emp; 
    8 FOR i IN 1..a.count 
    9 LOOP 
10  dbms_output.put_line (a(i).ename); 
11 END LOOP; 
12 END;

您還可以直接循環到光標像下面

FOR recc in order_id_cur 
    LOOP 
     DBMS_OUTPUT.put_line(recc.ORD_ID); 
    END LOOP;
