创建 Oracle 过程

2021-12-24 00:00:00 oracle stored-procedures plsql ora-06512

我正在尝试创建一个过程并且它创建时没有错误.但是，当我尝试运行它时，我会收到以下错误.请指教

I am trying to create a procedure and it created without error. However when I try to run it then I will get following error. Please advise

SQL> begin
  2   Update_STUD_Fin ( '1011');
  3  end;
  4  /
begin
*
ERROR at line 1:
ORA-06511: PL/SQL: cursor already open
ORA-06512: at "ORAIN.UPDATE_STUD_FIN", line 3
ORA-06512: at "ORAIN.UPDATE_STUD_FIN", line 8
ORA-06512: at line 2

程序是

SQL> CREATE OR REPLACE PROCEDURE Update_STUD_Fin ( AIDY_CODE IN VARCHAR2 ) IS
  2    CURSOR PublicationC IS
  3      SELECT SGidm from SGB
  4       WHERE SGCODE_EFF ='201030';
  5  BEGIN
  6    OPEN PublicationC;
  7  
  8    FOR PublicationR IN PublicationC
  9    LOOP
 10      DBMS_OUTPUT.PUT_LINE( PublicationR.SGidm );
 11    END LOOP;
 12  
 13    close PublicationC;
 14   
 15  END;
 16  /

Procedure created.

推荐答案

您不能显式地打开游标，也不能在隐式 FOR 循环中使用它.您可以选择隐式(FOR 循环)或显式(OPEN/FETCH/CLOSE).

You cannot explicity OPEN the cursor and also use it in an implicit FOR loop. You much choose either implicit (FOR loop) or explicit(OPEN/FETCH/CLOSE).
