How Do I Escape the Ampersand (&) Character in Oracle SQL Inserts?

Handling ampersands in Oracle SQL Developer

In Oracle SQL Developer, when using the SQL insert statement to insert special characters (such as &) into a string, you may be prompted to "Enter a replacement value". This is because the & character triggers the substitution variable function.

For example:

<code class="language-sql">insert into agregadores_agregadores
(
 idagregador,
 nombre,
 url
)
values
(
 2,
 'Netvibes',
 'http://www.netvibes.com/subscribe.php?type=rss\&amp;url='
);</code>

In this query, the & character breaks string replacement. You may have tried escaping the & character using ', but this was not successful.

The workaround is to disable the default DEFINE function, which assigns substitution variables to the & character. Execute the following command in SQL Developer:

<code class="language-sql">SET DEFINE OFF</code>

By doing this, you can bypass replacement and include the & character directly in the string without escaping or using the CHR(38) function.
