Views and columns in views...

Howdy,
I'm using Oracle-7 with Powerbuilder, and am running into problems with selecting from Views. From the PB Database administrator, I create a View; the View is actually a join across a couple of tables. Then, when I query the View and use a column from the View in a WHERE clause, I get an "Invalid column name" message. What am I doing wrong? Here's an example of the situation:
CREATE VIEW MyView (Column1, Column2, Column3) AS
SELECT TableA.Column1, TableA.Column2, TableB.Column3
FROM TableA, TableB
WHERE TableA.JoinCol = TableB.JoinCol
Then, selecting from this view as follows:
SELECT *
FROM MyView
works successfully, but
SELECT *
FROM MyView
WHERE Column1="somevalue"
returns with an "Invalid Column Name" message.
Any idea what's wrong here, or is this a limitation of Oracle's implementation of Views?
Thanks for any responses,
