用这段代码发疯了。任何人都可以让我走上正轨吗？我正在使用 SQL 开发 3.1.07。谢谢。

当我运行它时，它会返回这个错误：

【解决方案1】：

问题在于将旧的 Oracle 语法与 ANSI 连接语法混合在一起；例如，假设您有这些表：

create table t1(n1 number);
create table t2(n2 number);
create table t3(n3 number);

这就是你得到的：

SQL> select *
  2  from t1,t2
  3    left join t3 on t3.n3 = t1.n1
  4  where t1.n1 = t2.n2;
  left join t3 on t3.n3 = t1.n1
                          *
ERROR at line 3:
ORA-00904: "T1"."N1": invalid identifier


SQL> select *
  2  from t1
  3    inner join t2 on t1.n1 = t2.n2
  4    left join t3 on t3.n3 = t1.n1;

感谢您的回复。那我应该怎么做才能修复代码？谢谢。
好办法：完全切换到ANSI语法。捷径：编辑LEFT JOIN 部分并使用(+) 运算符进行外连接。我强烈推荐第一选择。
另外，请考虑一些工具（例如 Toad for Oracle）可以自动将查询从一种语法切换到另一种语法
谢谢 Aleksej。今天早上将检查 Toad，并尝试使用 ANSI 重写代码。
ANSI 代码工作起来很漂亮。感谢您的帮助 Aleksej。

【解决方案2】：

问题是你的左连接。可能缺少一列；你正在加入的那个。
