编译后出现错误：

Error(18,1): PL/SQL: SQL Statement ignored
Error(33,7): PL/SQL: ORA-00904: : invalid identifier

Answer 1

您尝试从SQL调用PROCEDURE。这是不允许的（因为它没有意义）。将package_info1更改为

function package_info1(param1 NUMBER, param2 NUMBER, param3 NUMBER)
    return number;

包标题中的

和

function package_info1(param1 NUMBER, param2 NUMBER, param3 NUMBER)
    return number IS
  v_is_incentivized  VARCHAR2(20);
  BEGIN
    SELECT is_incentivized
      INTO v_is_incentivized
      FROM package pk
     WHERE pk.id = 1;

    DBMS_OUTPUT.put_line('hi');
    RETURN 1;
  END;

在包体中，它将编译。不过，我真的建议你重命名你的PACKAGE表 - 这个名字会让你痛苦不已。

错误：PL / SQL：ORA-00904 ::无效的标识符
