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

I would like to set up a Windows XP environment with R and MySQL.
This set-up was recommended by a friend who uses this set up, but I
have been unable to get RJDBC to work. I have installed all of the
software today (June 2 2008), first deleting and then replacing old
versions of software.
The error is as follows:

I am trying to get the RJDBC and rJava .5to work on both my windows xp

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:

Creating a data table (frame?) from a SQL Statement?
Please always cc the list... the group usually has better answers than any one person, and I don't do private consulting on the net. For future reference, there is also an r-sig-db mailing list where this question really belongs.
Since I almost never use jdbc, I would need a reprex (hint you are ignoring my advice... a good way to get ignored), which this still isn't. There is probably

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.

R and/or REngine kills Java
Hi all,
I am using R and JRI under Windows XP Pro. I am posting this question
here since the reason might be R related (since I am running an R
script) but there is also a very good chance that it is JRI only
(since I am using the JRI interface to activate the script) -- in
which case I want to apologize for misplacing this message.
I have a method that instantiates an REngine object every time
