How do I ignore ampersands in a SQL script running from SQL Plus?

I have a SQL script that creates a package with a comment containing an ampersand (&). When I run the script from SQL Plus, I am prompted to enter a substitute value for the string starting with &. How do I disable this feature so that SQL Plus ignores the ampersand?

Solution 1:

This may work for you:

set define off

Otherwise the ampersand needs to be at the end of a string,

'StackOverflow &' || ' you'

EDIT: I was click-happy when saving... This was referenced from a blog.

Solution 2:

If you sometimes use substitution variables you might not want to turn define off. In these cases you could convert the ampersand from its numeric equivalent as in || Chr(38) || or append it as a single character as in || '&' ||.

Solution 3:

I resolved with the code below:

set escape on

and put a \ beside & in the left 'value_\&_intert'
