关于oracle sqldeveloper：sql code not working in oraclesqldeveloper: Invalid Character error

sql code not working in oraclesqldeveloper: Invalid Character error

我编写了一个代码来查找特定数字的几个项目，但它一直说这是一个"无效字符"。"ORA-00911：无效字符

00000 - "invalid character"
*Cause: identifiers may not start with any ASCII character other than
letters and numbers. $#_ are also allowed after the first
character. Identifiers enclosed by doublequotes may contain
any character other than a doublequote. Alternative quotes
(q'#...#') cannot use spaces, tabs, or carriage returns as
delimiters. For all other contexts, consult the SQL Language
Reference Manual.
*Action: Error at Line: 14 Column: 23"

我的大脑被炸毁了，我不确定问题出在哪里。

需要帮助。谢谢。
