ORACLE PL/SQL: 调用多参数存储过程函数（DML查询）

Question

这里有新 PL/SQL 人。我有一个（已成功编译）PL/SQL 功能块，它通过向其添加一个新术语来在我的数据库中操作 table：

create or replace FUNCTION add_new_term
    (TERM_ID_IN IN NUMBER, TERM_IN IN VARCHAR2, IS_METATERM_IN IN NUMBER)
    RETURN VARCHAR2
IS
    add_term CV_TERMS.TERM_NAME%TYPE; --TERM_NAME is VARCHAR2 type
BEGIN
    INSERT INTO CV_TERMS (TERM_ID, TERM_NAME, IS_METATERM)
    VALUES (TERM_ID_IN, TERM_IN, IS_METATERM_IN);
    dbms_output.put_line('New term successfully added to CV_TERMS table: ' || TERM_IN);
    RETURN add_term;
EXCEPTION
    WHEN DUP_VAL_ON_INDEX THEN
        raise_application_error (-20001, 'You have tried to insert a duplicate term.');
    WHEN OTHERS THEN    
        raise_application_error (-20002, 'An error has occurred inserting a term - '|| SQLCODE ||' -ERROR- '|| SQLERRM);
END add_new_term;

我像调用存储过程一样调用这个函数：

DECLARE
  add_term_success cv_terms.term_name%type;
BEGIN
  add_term_success := add_new_term(cv_terms_pk.NEXTVAL, 'TESTTT', 0);
END;

SQL开发人员告诉我程序已成功完成，但是该术语尚未添加到 table。我独立创建了序列 cv_terms_pk（它不在 table CV_TERMS' SQL 中）。它需要在那里吗？我传递不当吗？还是我的 add_term 声明有问题？想法？

在 DML INSERT 之后，您必须提交事务。

create or replace FUNCTION add_new_term
(TERM_ID_IN IN NUMBER, TERM_IN IN VARCHAR2, IS_METATERM_IN IN NUMBER)
RETURN VARCHAR2 IS
add_term CV_TERMS.TERM_NAME%TYPE; --TERM_NAME is VARCHAR2 type

BEGIN INSERT INTO CV_TERMS(TERM_ID, TERM_NAME, IS_METATERM VALUES (TERM_ID_IN, TERM_IN, IS_METATERM_IN); COMMIT; ---LINE ADDED ...
