Dear List, Java Exception error while reading large data in R from DB using RJDBC. I am trying to read large data from DB table(Vectorwise), using RJDBC connection. I have tested the connection with small size data and was able to fetch DB tables using same connection(conn as in my code). Please suggest where am i going wrong or alternate option to solve such issues while reading large DB

Hi Timo, Hi list, I finally got along to test the current dovecot 1.2 with our Kolab Server. And I'm very excited to see all the cool ACL and shared name spaces stuff upstream, thanks a lot Timo! Anyway I just stumbled across a new bug using our metadata-plugin (which in turn uses the dict back end): Making a few annotations requests after another it stops working. dovecot.log sais

Has anybody used RJDBC to read tables from an MS Access mdb file? I know how to do it with RODBC, and I have used RJDBC with SQL Server. I am, however interested now in this particular combination. Is it possible? -- View this message in context: http://n4.nabble.com/RJDBC-with-MS-Access-tp1470599p1470599.html Sent from the R help mailing list archive at Nabble.com.

Hello Simon, Hello everyone, I have a problem with retrieving database-queries chunkwise. In my query (Postgresql-Database, Postgres-Version 9.1) dbHasCompleted seems to always return TRUE. dbGetQuery works for smaller tables, but not for the whole query, since then a Heap-Overflow-Error will occur (and a Error: "java.lang.OutOfMemoryError: GC overhead limit exceeded" when trying to

Hello, I seem to have issues with setting the driver: My code: library(RJDBC) getStatic <- function() { # set driver driverClass <- JDBC("com.ibm.db2.jcc.DB2Driver","someClassPath.jar","'") conn <- dbConnect(driverClass,"serverName") etc etc } I get this error > data <-getData()

I need help. I'm trying to connect with an Oracle DBMS and MySQL DBMS, I'm using RJDBC package. My code is the next: library('rJava') library('DBI') library('RJDBC') //Mysql drv <- JDBC("com.mysql.jdbc.Driver","C:\\Temporal\\mysql-connector-java-3.0.9-stable-bin.jar","'") conn <- dbConnect(drv,

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. I am trying to append 'data' to the existing

After installing RJDBC on RedHat Linux and using it successfully with mySQL JDBC driver i am trying to use it with Oracle database. I use the JDBC driver that works fine elsewhere (use it in DBVizualizer). However, when i try to load the driver, drv<-JDBC("oracle.jdbc.driver.OracleDriver", "/home/az05625/DBdrivers/ojdbc6.jar", identifier.quote="`") it gives me

Rjdbc consistently gives me an execution error with postgresql 9.0s JDBC4 driver. It's probably something trivial so am including my code below: library("RJDBC") param <- 249 param2 <- 188129 postgres <- JDBC("org.postgresql.Driver", ".m2/repository/postgresql/postgresql/9.0-801.jdbc4/postgresql-9.0-801.jdbc4.jar") con <- dbConnect(postgres,

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: > library(RJDBC) Loading required

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

Trying to install the above two packages via the "install.packages("package_name")" command and the "R CMD INSTALL file.tar.gz". I receive the following error either way "sh: ./configure: /bin/sh: bad interpreter: Permission denied". I have tried to chmod and chown permissions and also ran dos2unix in hopes that there is a CRLF in some of the tar.gz files,

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
