使用：

  select name, id 
    from "TEST" 
   where id :2 
     AND name :1 
order by id desc

我收到ORA: 00904 "TEST"."NAME": invalid identifier错误，但奇怪的部分是我检查了我的测试表，它没有 NAME 字段，但它有 name 字段，我还检查了从该表和所有其他约束创建的所有引用，但它仍然给出我同样的错误。我不知道为什么，有没有一种方法可以检查数据库的所有列以获取 NAME 列名或任何其他推荐的调试方法将受到高度欢迎。

描述测试；名称空类型

id NOT NULL NUMBER(11)
名称 VARCHAR2(29)

SELECT *
FROM   ALL_TAB_COLS
WHERE  UPPER(COLUMN_NAME) = 'NAME';

将显示所有名为 NAME 的列

编辑：

根据您的评论，您是否缺少 WHERE 子句中的运算符？即=

select name, id
from   "TEST"
where  id :2      -- Surely you mean: id = :2
AND name :1       -- Surely you mean: name = :2
order by id desc

编辑2：

根据 SQL*Plus 输出，看起来您已经创建了具有小写列名的表。虽然这是可能且有效的，但通常只是艰苦的工作。我会用大写名称重新创建列。（正如亚历克斯所说）

编辑 3：

我认为...

SELECT "id", "name"
FROM   TEST
WHERE  "id" = :1
AND    "name" = :2
ORDER BY "id" desc;

应该管用

最好不要用双引号将列名和表名括起来，除非您知道自己在做什么并且确信自己需要它。

在 Oracle 中，数据库对象名称（包括表和列）不区分大小写并且假定为大写，除非您将它们包含在双引号中。

例如，如果一个表创建为TEST，它可以被称为test、Test或TesT或"TEST"。但是如果它被创建为"Test"，您将只能将其称为"Test"（在双引号中）。所有其他方式将导致“无效标识符”错误。
