RODBC and Oracle 11g Issue.....

I am running CentOS release 5.3. This is the 64 bit version.

R Version is "R version 2.10.0 (2009-10-26)"
RODBC version is "1.3-1"

I have installed unix-odbc version unixODBC-2.2.14, and configured it (odbcinst.ini and odbc.ini).

I've got the 11.1 Oracle instant client installed, and configured (and all the environment variables set).

iSQL works:

[ruser at akoyavsrv05 instantclient_11_2]$ isql -v OracleLocal parts parts

SQLRowCount returns -1
7 rows fetched

as does sqlplus:

[ruser at akoyavsrv05 instantclient_11_2]$ ./sqlplus parts/parts at VSRV06

But R does not seem to want to work:

R version 2.10.0 (2009-10-26)
Copyright (C) 2009 The R Foundation for Statistical Computing
ISBN 3-900051-07-0

[...]

Type 'q()' to quit R.

library(RODBC)
channel <- odbcConnect("OracleLocal", uid="parts", pwd="parts")
sqlQuery(channel, "select distinct segment from parts", errors=TRUE)

character(0)

sqlTables(channel)

Any ideas? The sqlQuery should return 7 rows, right?

Thanks in advance
