【问题描述】:
我是 PL/SQL 的新手,正在尝试使用 CURSOR。我想验证一个插入过程,所以我写了另一个过程来这样做。
CREATE OR REPLACE PROCEDURE verify_insert
IS
CURSOR map_cur IS
SELECT Page_ID_NBR, Page_Type, Page_Dcpn FROM SSC_Page_Map;
map_rec map_cur%ROWTYPE;
BEGIN
OPEN map_cur;
FOR map_rec in map_cur
LOOP
DBMS_OUTPUT.PUT_LINE('ID: ' || map_cur.Page_ID_NBR || ' ' || 'Type' || map_cur.Page_Type || ' ' || 'Description' || map_cur.Page_Dcpn);
END LOOP;
CLOSE map_cur;
END;
SHOW ERRORS PROCEDURE verify_insert;
我收到以下消息
[Warning] ORA-24344: success with compilation error
19/44 PLS-00225: subprogram or cursor 'MAP_CUR' reference is out of scope
19/5 PL/SQL: Statement ignored
(47: 0): Warning: compiled but with compilation errors
我也看到了
Errors for PROCEDURE VERIFY_INSERT
LINE/COL ERROR
-------- -----------------------------------------------------------------
19/44 PLS-00225: subprogram or cursor 'MAP_CUR' reference is out of sco
19/5 PL/SQL: Statement ignored
正如我所写的,我是新手,正在尝试从Oracle PL/SQL Programming (Feuerstein) 和网络拼凑 PL/SQL 知识。走到一起,但没有我想要的那么快。
