Coldfusion, Oracle translate problem

Question

We are using Coldfusion Server to connect to a oracle database.
When the translate function is used ie:
SELECT ejname
FROM Ej
WHERE
(Lower(translate(ejname,'h,H,I,i','e,e,e,e')) like '%#LCase(form.query)#%')
I find that using the translate function in this fashion it will mistake an 'i' for the letter e. So if form.query = 'i' it will return everything that starts with an 'e'. Anybody else have this problem?

Answer 1

First of all - this is an appliaction developed by someone
else, I'm just trying to get it to work again :( The strange thing
is that it worked fine until the oracle server was reinstalled.
I've triple checked, and there are no changes in the CF
application, the PL/SQL package or the database structure.
I'm not sure why threshold is declared differently in CF and
Oracle, but I've already tried changing it to
cf_sql_varchar, and it does not seem to make any difference.
Regarding
typ_vtx_result, this is declared in the package as shown
below.
AS
TYPE typ_vtx_result IS REF CURSOR RETURN dual%ROWTYPE;
PROCEDURE proc_vtx_search(
url IN VARCHAR2,
filename IN VARCHAR2,
shape IN VARCHAR2,
color IN VARCHAR2,
texture IN VARCHAR2,
spatial IN VARCHAR2,
threshold IN VARCHAR2,
images OUT typ_vtx_result);
END vtx;
