A problem with "=" in my query

Question

Hi all,
I tried to compare two elements in my database:
select * from table where upper(col1) ='CARRE';
it does return columns contain 'carré' because of the "é". Can somebody help me. Is there a parameter to set in oracle so that my query return what I want?

Answer 1

I used a copy-paste to get it into my insert statement (I use SQLTools as my editor: www.sqltools.net)
But the whole thing I suggest doesn't make any sense.... If you look at the Where condition, you'll see why.
I thought it worked the same as this:
create table t
(x varchar2(20))
insert into t
values ('große');
commit;
select Upper (x), Nls_Upper (x, 'nls_sort=xgerman')
  from t
GROßE GROSSEBut it doesn't...
If I use
insert into t
values ('carré')
select Upper (x), Nls_Upper (x, 'nls_sort=xfrench')
  from t
/this is the result:
CARRÉ CARRÉThe last character, the "é" gets turned into an "É", so the whole NLS_ works differently than I though. That's what you get when you jump to conclusions. My mistake.
