我正在为网站的一部分创建一个新的 Oracle 包。当我运行包时，我得到六个结果，当我直接运行 SQL 时，我得到八个结果。我现在对所有内容都进行了硬编码，因此 SQL 没有任何动态。因为我使用的是精确的硬编码 SQL，所以我不明白它们是如何得到不同的结果的。

PACKAGE RESULTS:
    BEGIN
    DBMS_OUTPUT.ENABLE (1000000);
    INTERNET.Appt.GetAppointments(:p_OpenAppointments);
    END;

CREATE OR REPLACE PACKAGE INTERNET。"Appt" AS 类型 ResultSet 是引用游标；

procedure GetAppointments(
    p_Appointments OUT ResultSet );

结束申请；/

procedure GetAppointments(
        p_Appointments OUT ResultSet )
    IS
        v_sql varchar2(5000);
    BEGIN

OPEN p_Appointments FOR
