Oracle存儲過程：返回多行

Question

在我的存儲過程中，它需要獲取輸入並將多行返回給前端應用程序。

但是，存儲過程會產生錯誤：

• SQL語句被忽略
• 值不足

怎么解決？

對象類型

CREATE TYPE org_rspnsble_prsns_type 
    AS OBJECT (
    "appId" varchar2, 
    "orgId" varchar2, 
    "domainId" varchar2, 
    "leadName" varchar2, 
    "personId" number
);

桌子類型

CREATE TYPE org_rspnsble_prsns_table 
AS TABLE OF org_rspnsble_prsns_type;

儲存程序

CREATE OR REPLACE PROCEDURE GetNames( appIdInput IN varchar2, orgIdInput IN varchar2, p_arr OUT org_rspnsble_prsns_table )
AS
BEGIN
    SELECT "appId", "orgId", "domainId", "leadName", "personId"
    BULK COLLECT INTO p_arr
    FROM (
        select "appId", "orgId", "domainId", "leadName", "personId"
        from tableA
    UNION
        select "appId", "orgId", "domainId", "leadName", "personId"
        from tableB
    )
    WHERE "appId" = appIdInput
    AND "orgId" = orgIdInput;
END;

我從以下位置找到了一種很好的方法： https : //asktom.oracle.com/pls/apex/ASKTOM.download_file?p_file=6551171813078805685

create or replace package types 
as 
    type cursorType is ref cursor; 
end; 
/
create or replace function sp_ListEmp return types.cursortype 
as 
    l_cursor    types.cursorType; 
begin 
    open l_cursor for select ename, empno from emp order by ename;
    return l_cursor; 
end; 
/
create or replace procedure getemps( p_cursor in out types.cursorType )
as
begin
open p_cursor for select ename, empno from emp order by ename;
end;
/

謝謝所有回答的人。

您的SELECT選擇1變量中的5列。 你必須
A）在您選擇的對象中創建：

SELECT org_rspnsble_prsns_type("appId", "orgId", "domainId", "leadName", "personId")
BULK COLLECT INTO p_arr
...

或B）將類型創建為記錄：

CREATE TYPE org_rspnsble_prsns_type 
AS RECORD (...
