在 MS Access 中与左连接作斗争

Question

我遇到了 MS Access 的问题，因为我不太熟悉 Access SQL。 由于 Access 将左联接的条件置于联接子句之外，因此我的左联接被视为内部联接。我在这里查看了其他一些主题，但没有找到可以解决我的问题的建议。非常感谢任何帮助！

Access Visual Designer 输出的原始查询：

我如何在 Oracle SQL 中设计它以获得我想要的结果：

更新添加，我按照@jarlh尝试了以下建议，我的访问数据库崩溃而不是出错：

Ms-Access SQL 对括号可能有点挑剔；试试这个：

SELECT

          ) 
          INNER JOIN STUDENT_TYPE AS STYP 
          ON SGBS.SGBSTDN_STYP_CODE = STYP.STUDENT_TYPE_CODE
