select * from table_name where column like '&nbsp'

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. I guess the database thinks that nbsp is a parameter. I am wondering if the is an escape character so that I can tell the database that "&" is part of my query string. I tryed '\&nbsp' but didn't work.

My environment is Oracl开发者_JS百科e 9i with sqlplus client.

Thanks.

Have a look at this:

SQL Plus FAQ

e.g.

SET ESCAPE '\'
SELECT '\&abc' FROM dual;

Easier way:

SET DEFINE OFF

See: SET DEFINE

The backslash should work, but I think you need to start your query with

SET ESCAPE ON

In PL/SQL, you would use:

BEGIN select <Column> from <Table_name> into <Variable> where <Column> LIKE '\&nbsp\%' ESCAPE '\'; END /
