Sort Error - failed to parse query

Question

I'm using APEX 2.2.1 .
I have a very detailed report, I wanted to implement a sorting feature into it, where you can click on the title and it'll sort asc or desc. Well Through reading my trusty Oracle manual I decided that a sort option would be the way to go.
The detailed report had all the columns I wanted to be sortable enabled, and I ran it and I get :
failed to parse SQL query:
ORA-00911: invalid character
I have gone down to only having one column checked with sort, and the Sort Sequence is set. No matter how I set this up I get the error. I then decided I'd put in a simple query into a report, to see if it worked at all:
select * from super_user; - this return 2 columns and 2 rows.
I get the same error when I try and enable sorting on this... What am I doing wrong?

Answer 1

Literally 2 seconds after posting this I re-read it and saw that I have a semicolon after my query. I thought to myself "Self - how could it amend any sorting info if you're doing this?"
I removed the semicolon and it worked.
