谢谢

将显示名为NAME的所有列

编辑：

根据您的评论，您是否缺少WHERE子句中的运算符？即=

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

编辑2：

基于SQL*Plus输出，看起来您已经创建了具有小写列名的表。虽然这是可能和有效的，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：

我想

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

应该可以用

除非您知道自己在做什么并且确信自己需要它，否则最好不要用双引号括住列和表名

在Oracle中，数据库对象名称（包括表和列）不区分大小写，除非包含在双引号中，否则采用大写

例如，如果一个表被创建为TEST，那么它可以被称为TEST、TEST或TEST或TEST。

但如果它被创建为Test，您将只能用双引号将其称为Test。所有其他方法都将导致无效标识符错误。

从测试中选择name，id，其中id:2和name:1 order by id desc是我尝试运行的查询。此外，该应用程序是数据库驱动的，并且有许多表在这方面相互关联。这是清楚的还是需要我进一步澄清？如果我理解正确，您仍然需要添加equals运算符。您得到的错误与列无关。。。这是因为您的SQL语句不正确。您需要将=添加到WHERE子句中。您是说列名在所有的\u tab\u列中都显示小写？这意味着您在创建表时将其用双引号括起来。通常Oracle对对象名不区分大小写，但您可以强制它以不同的方式进行操作—不确定您为什么要这样做。从错误消息中可以看到，它在内部将其转换为大写。所以您可以从测试中选择name，id，其中id=：2和name=：1？但是你似乎让自己的生活变得很艰难。你可以重新命名这些专栏吗？ALTER TABLE TEST将列id重命名为id；ALTER TABLE TEST将列名重命名为name；符合事实的这可能是短期的痛苦，但长期的收益？这取决于你需要修改多少代码，但如果从长远来看这能让它变得更容易，那可能是值得的。根本不确定Java/SP与SQL的关系；我有一种可怕的感觉，尽管完全没有证据，框架可能正在用绑定变量做自己的事情。我想知道args[]；您似乎只给它一个数字值，我假设它是id，所以它可能找不到name的值，框架正在破坏发送到Oracle的实际查询。有点牵强，但可以尝试省略名称/：2检查并查看它的功能。享乐
