Are you using the 'schema' attribute of the <Table> element? You should be.
I have a feeling that you're doing funny stuff like putting '"."' in table
names - if so, that's bound to confuse things.

Apparently I screwed up the previous message because i attached a file...
Sorry about that, Anyway, here it goes again without attachment... (In case
that the message is duplicate I am Double sorry, I'm just new here and need
help)
Julian, thanks for the response, unfortunately I am still having problems, I
now don't have the problem with the '>' delimiter. What I did was create a
new cube definition, very simple so I can test it. I modified the xml so it
includes de Database name, but none of the .xml worked. Teradata is not case
sensitive so that isn't a problem, but the query that mondrian is creating
is not working, Maybe I added the DB name in too may places (I added in
every 'Table' and 'Table name' field). I modified the query from the
modified definition so that it would work in teradata, the 'correct' query
would be:
select sum("GC_LiDEr_WRK"."TBL_CUBO_CLIENTES_MCL_3000"."MONTO_CHEQUE") as
"m0"
from "TBL_CUBO_CLIENTES_MCL_3000"
Instead of the original:
select sum("GC_LIDER_WRK"."TBL_CUBO_CLIENTES_MCL_3000"."MONTO_CHEQUE") as
"m0" from "GC_LIDER_WRK"."
TBL_CUBO_CLIENTES_MCL_3000" as "GC_LIDER_WRK"."TBL_CUBO_CLIENTES_MCL_3000"
I hope you can help me a bit more, I feel I'm getting close. Thanks a
million.
PS: I dont think it matters, but the JDBC driver I use in cube designer is
older that the one in Design Studio, for some reason the new one does not
connect in CD and the old one doesn't connect in DS.
PSS: Apparently I can't attach files here and to post the entire error logs
+ the definitions would be a bother to everyone, If more information is
needed just ask.

Two errors here. First, it can't find the object. Have you maybe spelled the
table in lowercase in your schema file, and it is uppercase in Teradata; or
perhaps it needs to be qualified by a schema name in teradata. Turn on SQL
tracing (mondrian.trace.level=1) and see what SQL mondrian generates, then
try running that SQL using teradata's command line.
Second, when you changed the schema.xml file you made it into invalid XML. I
think you forgot to terminate the <Level> element with />. Maybe you tried
to put comments inside the Level element?

Subject: [Mondrian] I need help conecting to Teradata
Hello, I've been using Mondrn with Pentaho BI Suite and for some reason I
can't connect to Teradata with Mondrian, I can make reports using my DB, the
problem only comes with Mondrian. Here's what I do:
I use Cube Designer to design and publish a cube, at this point I have no
problem accesing the data from Teradata, I can use the graphic interface
perfectly. In Cube designer I have to use the JDBC drivers version
03.01.00.102, If I use newer ones I can't connect... So far so good
Now to actually SEE the cube, The JDBC drivers defined in Jboss are version
12.0, here the version 3.01.00.102 simply don't work. So, I go to
localhost/samples/analysis and when I click on a SampleData cube I can see
it perfectly, but, a Teradatya cube... NOTHING, The only thing I see is the
message from Jboss that goes like this:
10:23:15,865 INFO [STDOUT] , exec+fetch 47 ms, 0 rows

(...And a lot more)
Which seems to be because the name of the Database itself is nowehre to be
found, it just references the tables. So, my natural instinct suggest me to
change the .xml and add the reference to the table... at this point I get
the following error:

PLEASE, at this point Im desesperate, I've searched every forum I've found
and I found nothing to help me, We have a lot of hope in this platform, but
at this point it's begining to be a lot of trouble. HELP!!
Thanks.

I have attached the code after I integrated it with the head revision. It is
in the format produced by the packChange utility, so it should be easy to
re-integrate with head in future.
Packchange is described here:
http://p4web.eigenbase.org/open/util/index.html
and can be downloaded from here:
http://p4web.eigenbase.org/open/util/bin/
It runs on linux and windows/cygwin.
