How to achieve line breaks when concatenating strings in Oracle?

In Oracle, you can use the special character ‘\n’ to represent a line break. By using the string concatenation operator ‘||’, you can combine strings with ‘\n’ to achieve a line break effect.

Here is an example:

SELECT 'Hello'|| chr(10) || 'World'
FROM dual;

In the example above, the line break is represented using chr(10), and by using the string concatenation operator ‘||’, the strings ‘Hello’, the line break, and the string ‘World’ are concatenated together to get the result with a line break.

Please note that the display of line breaks in search results may depend on the client tool you are using.
