SELECT does not work in View

Question

I have a select that runs well alone, but when i want to create a view with this select, i get the error "ORA-00933: SQL command not properly ended".
The select is of form
select
col1 as "one",
null as "two",
UNIONALL
select
abc as "one",
def as "two",
order by "one", "two"
the select alone works as expected. i also enclosed the select in "select * from ( ... )" and moved the order by outside. but it still has this error.
if i leave out the order by, the view creation works. but why? the select itself also works with the order by ...?

Answer 1

1) In Oracle 8 you could not use NULL as a column. You have to put to_char(null) or to_number(null). But in 9i you can use null without translation function. Also you can use ORDER BY, in 9i, in a view.
I did all what you said, on my 9i database, and it worked properly. So, I do not "obtain" that error.
2) Try to create the view without using double quote for aliases, even though it is correct what you've done.
3) Maybe is a stupid advice, but I dare:
Are you sure you haven't a comma(or something like this) before the order by clause. The explanation for this message error, in Oracle 8, is:
"ORA-00933: SQL command not properly ended
Cause: The SQL statement ends with an inappropriate clause. For example, an ORDER BY clause may have been included in a CREATE VIEW or INSERT statement.ORDER BY cannot be used to create an ordered view or to insert in
a certain order. Also, an improper SQL ending occurs if IN clause is used with only one argument (IN(X), for example). An IN clause must have two or more
arguments.
Action: Correct the syntax by removing the inappropriate clauses. It may be possible to duplicate the removed clause with another SQL statement. For example, to order the rows of a view, do so when querying the view and not
when creating it. This error can also occur in SQL*Forms applications if a continuation line is indented. Check for indented lines and delete these spaces."
