我正在创建一个有关获取输出值的过程。输出值在另一个过程中调用,并存储在数组中。
procedure get_value_temp
(
v_name_id in out varchar2,
v_event_id out varchar2
)
is
begin
select s.name_id,d.event_id into v_name_id ,v_event_id from aokk_kala_appreg_stage s inner join aokk_kala_appreg_det d
on s.name_id=d.name_id where s.name_id=v_name_id;
--return;
end;
以下是另一个过程。
declare
V_ARRAY MYTABLETYPE;
name_id varchar2(100);
BEGIN
V_ARRAY:=get_value_temp(220);--get output value and store in array.
FOR I IN V_ARRAY.FIRST .. V_ARRAY.LAST
loop
dbms_output.put_line(V_ARRAY(I));
END LOOP;
end;
请帮助我了解如何在数组中获取存储过程的输出值。

例如,假设您有此表:
create table myTab(n number, v varchar2(100));
insert into myTab(n, v) values (1, 'one');
insert into myTab(n, v) values (2, 'two');
insert into myTab(n, v) values (2, 'TWO');
您可以构建类似以下的过程
create or replace procedure myProc (p_n IN number, po_mytabletype OUT mytabletype) is
begin
select v
bulk collect into po_mytabletype
from myTab
where n = p_n;
end;
如果您这样称呼:
declare
v_mytabletype mytabletype;
begin
myProc(2, v_mytabletype);
for i in v_mytabletype.first .. v_mytabletype.last loop
dbms_output.put_line (v_mytabletype(i));
end loop;
end;
您得到:
two
TWO

根据我对您的要求的理解,这是示例代码演示,如果不符合您的要求,请分享更多详细信息。
CREATE OR REPLACE PROCEDURE get_value_temp(v_name_id IN VARCHAR2,
o_events_for_nameid OUT sys_refcursor) IS
BEGIN
open o_events_for_nameid
for select s.event_id from
(SELECT 'A' name_id, '1' event_id FROM dual UNION
SELECT 'A' name_id, '2' event_id FROM dual UNION
SELECT 'C' name_id, ' 3' event_id FROM dual UNION
SELECT 'D' name_id, '4' event_id FROM dual UNION
SELECT 'D' name_id, '5' event_id FROM dual UNION
SELECT 'E' name_id, '6' event_id FROM dual) s WHERE s.name_id = v_name_id;
END;
/
drop type mytabletype;
/
CREATE OR REPLACE TYPE mytabletype AS TABLE OF VARCHAR2(200); -- this is nested table definition
/
现在测试代码...
DECLARE
v_nested_table mytabletype := mytabletype();
o_events_for_nameid SYS_REFCURSOR;
BEGIN
get_value_temp(v_name_id => 'A',
o_events_for_nameid => o_events_for_nameid);
FETCH o_events_for_nameid BULK COLLECT
INTO v_nested_table;
FOR i IN v_nested_table.first .. v_nested_table.last
LOOP
dbms_output.put_line(v_nested_table(i));
END LOOP;
END;
