While attempting to execute SQL insert statements using Oracle SQL Developer I keep generating an "Enter substitution value" prompt:
insert into agregadores_agregadores
(
idagregador,
nombre,
url
)
values
(
2,
'Netvibes',
'http://www.netvibes.com/subscribe.php?type=rss\&url='
);
I've tried escaping the special character in the query using the '\' above but I still can't avoid the ampersand, '&', causing a string substitution.

the & is the default value for DEFINE, which allows you to use substitution variables. I like to turn it off using
SET DEFINE OFF
then you won't have to worry about escaping or CHR(38).
The real answer is you need to set the escape character to '\': SET ESCAPE ON
The problem may have occurred either because escaping was disabled, or the escape character was set to something other than '\'. The above statement will enable escaping and set it to '\'.
None of the other answers previously posted actually answer the original question. They all work around the problem but don't resolve it.
add this before your request
set define off;
|| chr(38) ||
This solution is perfect.
Set the define character to something other than &
SET DEFINE ~
create table blah (x varchar(20));
insert into blah (x) values ('blah&');
select * from blah;
X
--------------------
blah&
SELECT 'Free &' || ' Clear' FROM DUAL;
insert into AGREGADORES_AGREGADORES (IDAGREGADOR,NOMBRE,URL)
values (2,'Netvibes',
'http://www.netvibes.com/subscribe.php?type=rss' || chr(38) || 'amp;url=');
select 'one'||'&'||'two' from dual
