【问题描述】：
我刚刚开始编写 SQL 选择语句，但遇到了问题。我有一份完美运行的现有报告。但是，我被要求在结果集中添加一些字段。该文件位于具有外键关系的表中。我正在尝试将其添加到查询中，但我失败了。我可以单独编写 select 语句，它会返回正确的结果。我只是不知道如何将其添加到现有语句中。我尝试了左连接，将其添加到选择中，但结果集错误。我想添加以下内容以将信息返回给新列中的结果集，但如果为 null，则不阻止其他数据。
我想补充： 选择 sc.FACILITY_ID、ce.schd_id 来自 PA_SCHED sc、PA_CPNT_EVTHST ce 其中 sc.SCHD_ID = ce.schd_id
致以下：
select s.stud_id as studID, s.lname as lastName, s.fname as firstName, s.mi
