Question

我想将光标插入我的自定义tableObject，但并不总是找到它。

我的记录：

create or replace type "RECORDRANKING" as object
(

  -- Attributes
  COL1 NUMBER,
  COL2 VARCHAR(50),
  COL3 NUMBER

  -- Member functions and procedures
 -- member procedure <ProcedureName>(<Parameter> <Datatype>)
)

这是对象表：

CREATE OR REPLACE TYPE "TBRANKING" AS TABLE OF RECORDRANKING;

现在我开始创建一个函数（进入包）：

CREATE OR REPLACE PACKAGE BODY PKLBOTTONI as
FUNCTION testlb
( 
p_gapup IN NUMBER, 
p_gadown IN NUMBER
)
RETURN SYS_REFCURSOR IS
cursor_ranking SYS_REFCURSOR;
position NUMBER ;
gap_ranking TBRANKING;
gaprecord RECORDRANKING;
upgap NUMBER;
downgap NUMBER;
     BEGIN
      select * into cursor_ranking from(
        select pkranking.getRanking(  100 ) from dual); 

LOOP  
FETCH cursor_ranking INTO gap_ranking;
EXIT WHEN cursor_ranking%NOTFOUND;
   INSERT INTO gap_ranking       (COL1,COL2,COL3)
   VALUES 
   (cursor_ranking.C1,
   cursor_ranking.C2,
   cursor_ranking.C3);
 END LOOP;
return gap_ranking; 
END;


END PKLBOTTONI;

我总是得到：

Compilation errors for PACKAGE BODY PKLBOTTONI

Error: PL/SQL: ORA-00942: table or view does not exist
Line: 32
Text: INSERT INTO gap_ranking

在循环中，您将同时进入＆＃34; gap_ranking＆＃34;然后尝试插入＆＃34;它再次。插入集合不是有效的语法。可以在循环中使用Fetch，也可以使用批量收集一次获取多个记录。

从您的摘录中看，您看起来没有物理数据库表，因此在PL / SQL中执行此操作的方式如下所示。

有关使用集合的更多帮助，您也可以查看下面的Oracle文档： http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/collections.htm
