对这段代码感到疯狂。任何人都可以让我走上正轨吗？我正在使用SQL Develope 3.1.07。感谢。

当我运行它时，它会返回此错误：

ORA-00904：“PHA”。“PO_HEADER_ID”：标识符无效   00904. 00000 - “％s：无效标识符”   *原因：

Answer 1

问题是你的左连接。可能缺少一列;你加入的那个。

以下是您收到的错误的详细信息： https://www.techonthenet.com/oracle/errors/ora00904.php

Answer 2

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

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;

no rows selected

00904. 00000 - “％s：无效标识符”
