Oracle SQL escape character (for a '&')

Question

While attempting to execute SQL insert statements using Oracle SQL Developer I keep generating an \"Enter substitution value\" prompt:

insert into agregadore         


        

Answer 1

add this before your request

set define off;

Answer 2

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.

Answer 3

|| chr(38) ||

This solution is perfect.

Answer 4

SELECT 'Free &' || ' Clear' FROM DUAL;

Answer 5

insert into AGREGADORES_AGREGADORES (IDAGREGADOR,NOMBRE,URL)
values (2,'Netvibes',
'http://www.netvibes.com/subscribe.php?type=rss' || chr(38) || 'amp;url=');

Answer 6

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).
