问题描述

I need to find records containing html code such as '&nbsp' But when I try to run the select * from table_name where column like '&nbsp%' I got prompt asking for the value of nbsp. 我需要查找包含html代码的记录，例如'＆nbsp'但是当我尝试运行select * from table_name where column like '&nbsp%'我得到了nbsp的值。 I guess the database thinks that nbsp is a parameter. 我想数据库认为nbsp是一个参数。 I am wondering if the is an escape character so that I can tell the database that "&" is part of my query string. 我想知道是否是一个转义字符，以便我可以告诉数据库“＆”是我的查询字符串的一部分。 I tryed '\\&nbsp' but didn't work. 我尝试'\\ n'但是没有用。

My environment is Oracle 9i with sqlplus client. 我的环境是带有sqlplus客户端的Oracle 9i。

Thanks. 谢谢。

反斜杠应该可以工作，但我认为你需要开始查询

SET ESCAPE ON
