Dear R-SIG-Debian,
while trying to query data from an SQLite database through RODBC on

# but the same happens with SQLite driver

RODBC performance seems slow
I've noticed that RODBC seems to be an order of magnitude slower in
retrieving rows from a table than ODBC (or JDBC) access in other tools.
I'm wondering why that is, and whether there are things I can do to
improve performance beyond what I've tried. I've checked the
documentation, and have tried the rows_at_time= and buffsize= options,
which helped a little, but it is still

RODBC missing values in integer columns
Hello,
We are having some strange issues with RODBC related to integer columns.
Whenever we do a sql query the data in a integer column is 150 actual data
points then 150 0's then 150 actual data points then 150 0's. However, our
database actually has numbers where the 0's are filled in. Furthermore,
other datatypes do not have this problem: double and varchar are correct and
do not

calloc bug in RODBC 1.1-7 and later?
I'm trying to load Affy Annotation data from an Access database into R using
RODBC. This has worked fine for quite some time. The bug seems to be
correlated to RODBC versions 1.1-7 and later.
Works fine: R 2.2.0 with RODBC 1.1-4; R 2.3.0 or R 2.4.1 with RODBC 1.1-6
Fails: R 2.3.1 with RDOBC 1.1-7; R 2.4.1 with RODC 1.1-7 or 1.1-8

2. If not, is there some more appropriate way from w/in R to pull large data sets (2-5GB) into .rda files from sql?

Question regarding S4 objects and reading in excel data with RODBC
L.S.
I am trying to get data from an excel sheet using the RODBC library, quite
like the example on page 34 of the 'Data manipulation with R' book written
by Phil Spector. It seems very straightforward, yet I get the same error
everytime I try it, with different excel sheets and trying to tweek the code
a bit. This is what I do:

RODBC Excel sqlQuery insert into
I have searched the archives for using insert into to update spreadsheets
using RODBC and have come up short. So, first off, is it possible?
I have put together a dummy xls table (c:\foo.xls)for exploring
possibilities of RODBC. Ultimately, I am interested in replacing much of
our previous use of vba macros with R ( I'd prefer elimination, but will
take what I can get ). In order to
