oracle 过程中忽略的语句

Question

我正在尝试创建 return table 的过程。为此，我创建了如下的对象和过程。但它给了我编译时错误，

CREATE TYPE INTERN_OBJECT AS OBJECT
( companyTitle VARCHAR2(100),
  schoolName VARCHAR2(30),
  RANK NUMBER(3),
  NUM_INTERNS NUMBER(3));

CREATE TYPE INTERN_TAB AS TABLE OF INTERN_OBJECT;

CREATE OR REPLACE FUNCTION INTERN_DATA_Function RETURN INTERN_TAB
IS
  r_INTERN_TAB INTERN_TAB;
  r_index number := 0;
BEGIN
  r_INTERN_TAB := INTERN_OBJECT();
  FOR r IN (select company.title AS title ,school.name AS name ,RANK AS RANK ,count(SID) AS NO_OF_INTERN from school join student on school.SCHID = student.SCHOOLID JOIN INTERN on student.SID = INTERN.SID JOIN COMPANY ON INTERN.CMPID = COMPANY.CMPID GROUP BY company.title,school.name,RANK ORDER BY count(SID) DESC)
  LOOP
          r_INTERN_TAB.extend;
      r_index := r_index + 1;  
      r_INTERN_TAB(r_index):= INTERN_TAB(r.title, r.name ,r.RANK , r.NO_OF_INTERN);
    END LOOP;
  return r_INTERN_TAB;
END;

当我点击运行时出现以下错误：

ERROR at line 11: PL/SQL: Statement ignored
1. CREATE OR REPLACE FUNCTION INTERN_DATA_Function RETURN INTERN_TAB
2. IS
3.   r_INTERN_TAB INTERN_TAB;

我不知道问题在哪里。请帮助我。

您需要在每个语句后添加一个 /，特别是如果您运行上面的脚本 SQL*Plus:

CREATE TYPE INTERN_OBJECT AS OBJECT
( companyTitle VARCHAR2(100),
  schoolName VARCHAR2(30),
  RANK NUMBER(3),
  NUM_INTERNS NUMBER(3));
/

CREATE TYPE INTERN_TAB AS TABLE OF INTERN_OBJECT;
/

CREATE OR REPLACE FUNCTION INTERN_DATA_Function RETURN INTERN_TAB
IS
  r_INTERN_TAB INTERN_TAB;
  r_index number := 0;
BEGIN
  r_INTERN_TAB := INTERN_OBJECT();
  FOR r IN (select company.title AS title ,school.name AS name ,RANK AS RANK ,count(SID) AS NO_OF_INTERN from school join student on school.SCHID = student.SCHOOLID JOIN INTERN on student.SID = INTERN.SID JOIN COMPANY ON INTERN.CMPID = COMPANY.CMPID GROUP BY company.title,school.name,RANK ORDER BY count(SID) DESC)
  LOOP
          r_INTERN_TAB.extend;
      r_index := r_index + 1;  
      r_INTERN_TAB(r_index):= INTERN_TAB(r.title, r.name ,r.RANK , r.NO_OF_INTERN);
    END LOOP;
  return r_INTERN_TAB;
END;
