使用：
select name, id
from "TEST"
where id :2
AND name :1
order by id desc
我正进入（状态 ORA: 00904 "TEST"."NAME": invalid identifier 错误，但奇怪的部分是我检查了我的测试表，它没有名称字段，但它具有名称字段，我还检查了所有从该表和所有其他约束的引用，但仍然给我同样的错误。我不知道为什么，有没有办法可以高度欢迎数据库名称名称或任何其他debuggind方法的数据库列的所有列。
DESC测试；名称null类型
ID不是零号码（11）
名称varchar2（29）
选择了2行
编辑
DESC TEST
Name Null Type
------------------------------ -------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
ID NOT NULL NUMBER(11)
NAME VARCHAR2(29)
2 rows selected
Java代码
public String searchExecute(HttpServletRequest req, javax.servlet.ServletContext ctx, String nextPage){
// ESCA-JAVA0266:

// ESCA-JAVA0266:
System.out.println("name:"+req.getParameter("s_1984"));
boolean bDisplayAll = StringUtils.stringToBoolean(req.getParameter("display_all"));
if(bDisplayAll)
// ESCA-JAVA0034:
req.setAttribute("c_display_all", "Y");
req.setAttribute("c_search_submitted", "Y");
return nextPage;

SELECT *
FROM ALL_TAB_COLS
WHERE UPPER(COLUMN_NAME) = 'NAME';
将向您展示所有称为名称的列
编辑：
根据您的评论，您难道不是错过Where子句中的操作员吗？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：
基于SQL*Plus输出，看起来您已经创建了具有低案例列名称的表。尽管这是可能的，而且有效，但通常只是艰苦的工作。我会用大写名称重新创建列。 （就像亚历克斯所说）
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
其他提示
除非您知道自己在做什么并且有信心需要的，否则不要包围具有双重引用标记的列和表名是一个好主意。
在Oracle中，数据库对象名称（包括表和列）不适合病例敏感，并且假定为上案例 除非 您将它们包含在双重报价中。
例如，如果表格创建为 TEST, ，可以称为 test, Test 或者 TesT 或者 "TEST"。但是，如果它被创建为 "Test", ，您只能将其称为 "Test" （以双重引号）。所有其他方法都会导致“无效标识符”错误。
