Oracle: Pattern for to_char(number) to add additional ascii characters?

Question

Using the Oracle to_char(number) function, is it possible to append ascii characters to the returned string?

Specifically, I need to add a percentage character to the returned string.

"select to_char(89.2244, '999G999G999G999G990D00') from dual" --> returns "89.22". I need a format pattern that returns "89.22%".

I am using this through reports in Application Express, so cannot simply concatenate "%" to the query, i need to put it in the number format.

Answer 1

So you can't wrap the to_char with a CONCAT?

select concat(to_char(89.2244, '999G999G999G999G990D00'),'%') from dual

Answer 2

You can't do it right in the number format.

If you are able to change NLS_CURRENCY for you session, you can do the following:

SELECT  TO_CHAR(1.2, '999G999G999G999G990D00L' /*, 'NLS_CURRENCY=%' */)
FROM    dual
