让我们创建两个测试程序:
CREATE OR REPLACE PROCEDURE Aaaa_Test1(
pDog SYS_REFCURSOR
) IS
TYPE tDogRec is record (objid varchar2(7), lim number, debt number);
TYPE tDog IS TABLE OF tDogRec;
vDog tDog;
BEGIN
IF pDog%ISOPEN THEN
FETCH pDog BULK COLLECT INTO vDog;
IF vDog.count >= 1 THEN
FOR i IN vDog.First..vDog.Last LOOP
Dbms_Output.Put_Line('Aaaa_Test1 = '||vDog(i).Objid);
END LOOP;
END IF;
END IF;
END; -- Aaaa_Test1 Procedure
/
CREATE OR REPLACE PROCEDURE Aaaa_Test2(
pDog SYS_REFCURSOR
) IS
TYPE tDogRec is record (objid varchar2(7), lim number, debt number);
TYPE tDog IS TABLE OF tDogRec;
vDog tDog;
BEGIN
IF pDog%ISOPEN THEN
FETCH pDog BULK COLLECT INTO vDog;
IF vDog.count >= 1 THEN
FOR i IN vDog.First..vDog.Last LOOP
Dbms_Output.Put_Line('Aaaa_Test2 = '||vDog(i).Objid);
END LOOP;
END IF;
END IF;
END; -- Aaaa_Test2 Procedure
然后让我们尝试打开游标并按顺序将其传递给这些程序:
DECLARE
Vcdogcur SYS_REFCURSOR;
BEGIN
OPEN Vcdogcur FOR
select '6518535' objid, 10000 lim,0 debt
from dual
union all
select '6518536', 0,500
from dual
union all
select '5656058', 0,899
from dual
union all
select '2180965', 5000,0
from dual
union all
select '2462902', 0,100
from dual;
Aaaa_Test1(Vcdogcur);
Aaaa_Test2(Vcdogcur);
CLOSE Vcdogcur;
END;
如您所见,我不能在第二个过程中使用已经获取的游标,因为 ORACLE 游标是向前只读的。有什么方法可以帮助解决这个任务?
我不能简单地将这些程序合二为一。需要将它们的逻辑彼此分开。
