我有一个PL / SQL存储过程需要返回一个RefCursor类型对象作为输出参数。
PROCEDURE usp_appnt_stts_driver_wraper2
( in_req_src_system_id IN NUMBER,
in_req_user_info IN VARCHAR2,
out_response_rec1 OUT SYS_REFCURSOR)
在SP结束时，我可以使用Select语句将 Hard Coded 值返回到我的前端。
OPEN out_response_rec1 FOR
SELECT 'data1', 'data2', 'data3', 'data 4' FROM DUAL;
这很好用。但是我需要发送我从数组中获取的数据。
Array填充如下，
FOR g_index IN g_slsnetoutbndarr.FIRST..g_slsnetoutbndarr.LAST
LOOP
out_response_rec.EXTEND;
IF g_SlsnetOutbndArr(g_index).Rectypdesc IS NOT NULL THEN
out_response_rec(g_index).Rectypdesc := g_SlsnetOutbndArr(g_index).Rectypdesc ;
out_response_rec(g_index).Recdetltcode := g_SlsnetOutbndArr(g_index).Recdetltcode;
out_response_rec(g_index).RecDetlDesc := g_SlsnetOutbndArr(g_index).RecDetlDesc ;
END IF;
END LOOP;
因此，在此代码的末尾，数组对象out_response_rec具有我需要的所有值。
但是如何在RefCursor输出参数中传输这些值？
更新1
我尝试在Package规范中创建一个新的数据类型。
TYPE SlsnetOutbndRec IS RECORD(
Rectypdesc VARCHAR2(30),
Recdetltcode NUMBER,
RecDetlDesc VARCHAR2(130));
TYPE SlsnetOutbndTabArr IS TABLE OF SlsnetOutbndRec;
最后，我尝试将数组转换为SP中的表格
OPEN out_response_rec_result FOR
SELECT * FROM TABLE (Cast(out_response_rec AS SlsnetOutbndTabArr));
但这会引发Invalid Data Type错误。 SP无法识别我创建的新数据类型。

如果要在SQL语句中使用它们（在Oracle 12之前的版本中），则需要在SQL范围（而不是PL / SQL范围）中创建类型：

然后您可以在您的程序中使用它（假设您的第三方数据类型是集合或CREATE TYPE SlsnetOutbndRec IS OBJECT(
Rectypdesc VARCHAR2(30),
Recdetltcode NUMBER,
RecDetlDesc VARCHAR2(130)
)
/
CREATE TYPE SlsnetOutbndTabArr IS TABLE OF SlsnetOutbndRec
/
）：
VARRAY如果第三方数据类型是关联数组，则：
PROCEDURE usp_appnt_stts_driver_wraper2(
in_req_src_system_id IN NUMBER,
in_req_user_info IN VARCHAR2,
out_response_rec_result OUT SYS_REFCURSOR
)
IS
out_response_rec SlsnetOutbndTabArr := SlsnetOutbndTabArr();
g_slsnetoutbndarr ThirdPartyDataType := Get_From_3rd_party_Package();
BEGIN
FOR i IN 1 .. g_slsnetoutbndarr.COUNT LOOP
IF g_SlsnetOutbndArr(i).Rectypdesc IS NOT NULL THEN
out_response_rec.EXTEND;
out_response_rec := SlsnetOutbndRec(
g_SlsnetOutbndArr(i).Rectypdesc,
g_SlsnetOutbndArr(i).Recdetltcode,
g_SlsnetOutbndArr(i).RecDetlDesc
);
END IF;
END LOOP;
OPEN out_response_rec_result FOR
SELECT *
FROM TABLE( out_response_rec );
END;
答案 1 :(得分：0)
所以在这段代码的末尾，数组对象out_response_rec全部都是 我需要的价值。
但是如何在RefCursor输出参数中传输这些值？
根据我的理解，您希望使用SYS_REFCUSOR来获取Query的输出以及collection中由另一个Procedure填充的值}。我已经为您的要求提出了一个解决方案，请参阅下面的内联解释：
--Create a Object in Place of Record since we cannot use a PLSQL scope compnenet in SQL scope in Oracle 11g and below
CREATE OR REPLACE TYPE SlsnetOutbndRec IS OBJECT
(
Rectypdesc VARCHAR2 (30),
Recdetltcode NUMBER,
RecDetlDesc VARCHAR2 (130)
);
--Create a table type of the Object
CREATE OR REPLACE TYPE SlsnetOutbndTabArr IS TABLE OF SlsnetOutbndRec;
/
--Procedure
CREATE OR REPLACE PROCEDURE combined_rslt (var OUT SYS_REFCURSOR)
AS
v_var SlsnetOutbndTabArr := SlsnetOutbndTabArr ();
l_var SlsnetOutbndTabArr := SlsnetOutbndTabArr ();
BEGIN
--Populating the collection
v_var.EXTEND;
v_var (1) := SlsnetOutbndRec ('ABC', 1, 'A');
OPEN VAR FOR
SELECT 'CDE', 2, 'B' FROM DUAL
UNION ALL -- Combining the result of collection with the result of query
SELECT *
FROM TABLE (v_var) t;
EXCEPTION
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line (SQLERRM);
END;
执行：
DECLARE
x SYS_REFCURSOR;
a VARCHAR2 (30);
b NUMBER;
c VARCHAR2 (130);
BEGIN
combined_rslt (var => x);
LOOP
FETCH x INTO a, b, c;
EXIT WHEN x%NOTFOUND;
DBMS_OUTPUT.put_line (a || ' ' || b || ' ' || c);
END LOOP;
END;
结果：
SQL> /
CDE 2 B
ABC 1 A
PL/SQL procedure successfully completed.
