similar to: dbHasCompleted() always returns TRUE for POSTGRES Database with RJDBC?

All, In the following, when I just enter R from UNIX and make a connection to Oracle database, dbHasCompleted(rs) is TRUE. This shouldn't have happened since I haven't fetched any thing. Help will be appreciated. -MY --------------------------------------------------------------------- MyUnixMachine% R R : Copyright 2003, The R Development Core Team Version 1.7.0 (2003-04-16) R is

I'm trying to use RSQLite statement to cycle through a large database in "chunks" via the fetch(...,n=20000). As far as I can tell, however, it keeps re-fetching the same beginning set of rows -- any ideas what might be wrong with the following code? The select statement is pulling from multiple tables. I apologize in advance -- the DB is about 4gb so I can't make it easily

Hello, I have trouble installing and loading the RMySQL package on OS X 2.8. The package seems to install from source fine (using R package manager from within the R environment). I have the following error when I try to load the package: loading package: RMySQL Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

I'm having trouble getting RMySQL to load. I was able to build it and install it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37. I've read many postings about this but have not found a mention of my particular problem (some closely related). I get the "unable to load shared library, no such file" error, but all the files do exist, RMySQL.so and

Dear R experts, I try to extract certain child nodes from an XML document and construct a table in which the parent node names are the columns and the child id values, joined in a list, are the cell content. If I first apply an XPath query to extract all above parent nodes, then iterate over those nodes and again apply a XPath query to select their child nodes, I get *ALL* matching child nodes

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

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

Hi, I use RMySQL to connect to MySQL server where I have a couple of stored procedures.

Rjdbc consistently gives me an execution error with postgresql 9.0s JDBC4 driver.
