How to Escape Ampersands (&) in Oracle SQL Queries?

Oracle SQL to the righteous character (for '&')

When writing SQL queries in Oracle SQL DEVELOPER, due to the existence of special characters (such as &), users may encounter a prompt of input and replacement value. This is particularly frustrating when trying to insert data containing such characters.

One of the solutions of the special character in the Oracle SQL rotation is to use the back slope () symbol. However, in the code provided, this method seems invalid, because & still trigger string replacement.

In order to solve this problem, it is recommended to use Set Define OFF, which will disable the replacement variable. In this way, SQL Developer will no longer interpret & as replacement variables, but regards it as a literal character.

Implement this command in the code provided:

Using Set Define OFF, you can execute the SQL statement without encountering any replacement prompts, and & will be regarded as part of the URL string. This effectively allows you to insert data containing special characters into the database.

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

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