我的示例代码。

在 where 条件内的 case 语句中，当我等同于变量时，我收到以下错误：

ORA-00905-缺少关键字

我不明白我哪里出错了。

我什至尝试将完整的 case 语句等同于变量，它没有给出所需的输出。

谁能帮我？

我编辑了你的代码，使用stackoverflow的语法高亮，错误变得很明显。您缺少 ' 就行了：

(:LV_ACTN = '3' OR :LV_ACTN = '4') THEN X' END) IS NOT NULL

好的线路是：

(:LV_ACTN = '3' OR :LV_ACTN = '4') THEN 'X' END) IS NOT NULL
