RJDBC and multiple classpaths
Corect me if this is not the right place to post this.
I have a mdbdriver.jar (to access an MSAccess file) under Linux. I bought
the license from http://www.csv-jdbc.com/ guys. The driver work fine when
tested with DBVisualizer or another JDBC thing.
The problem is that driver needs 3 other more jar files to work. Under R I
have tried this and does not work:

RJDBC in Ubuntu
Hi,
I'm working with R on Cassandra and need to install RJDBC on my Ubuntu
virtual machine. The traditional commands (install.packages(RJDBC, dep=TRUE)
and library(RJDBC)) don't work: they throw an error that they can't find the
package. I tried installing it using the Rkward GUI, but can't write to any
of the pre-set directories because of permissions issues. When I try running

append rows to Sybase datatable using RJDBC
Hi,
Does anyone have experience using RJDBC library to write to Sybase
datatable? The jdbc driver I am using is jConnect 6.0. I can
successfully write into a new datatable, but have problem appending rows
to existing one. It either complains "Table *** already exists" or
simply overwrite the existing one. Here is the example.

Using SQL "IN" with RJDBC or RMySQL
Hello,
The code below works fine up until I try to use the "IN" statement in
the last line. The proper SQL format is:
SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5)
But, I think I may be getting something like:
SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5)
Which makes no sense in SQL. I think it may be just a matter of string
massaging, but I'm not

RJDBC vs RMySQL vs ???
I am running a simple SQL SELECT statement that involvs 50k + data
points using R and the RJDBC interface. I am facing very slow response
times in both the RGUI and the R console. When running this SQL
statement directly in a SQL client I have processing times that are a
lot lot faster (which means that the SQL statement itself is not the
problem).
Did any of you compare RJDBC vs RMySQL or is
