RODBC: sqlUpdate doesn't handle properly POSIXct field?
Hello all!
Can someone confirm whether there is a bug or not?
I was trying to use sqlUpdate in place of sqlSave as data set I import has duplications. However I get errors while using fast=FALSE argument to safely update/ignore duplicates:

RODBC and schemas
I have found that the "schema.table" syntax used in Postgresql (and
Oracle) does not work directly with RODBC.
This works
library(RODBC)
con<-odbcConnect("mydb")
d<-sqlQuery(con,"select * from meso.trees")
However this does not.
d<-sqlFetch(con,"meso.trees")

New RODBC: a problem with sqlSave
Till yesterday I was more than satisfied by RODBC, specifically by
sqlSave which I had been happily using in a daily crontab R batch job
regularly updating a postgresql db for as long as one year. In this R-
batch I was able to save records into indexed tables *** even though
*** they already existed. in this case sqlSave simply neglected those
rows of the input table that were offending the

Problem with RODBC sqlSave
Hi,
I'm able to establish a successful odbc connection using RODBC 1.3-2 on Win

RODBC: problem saving a new table in an "Excel database"
Hi
I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows

I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I

some helpful tips on using RODBC
Hey everyone,
I don't have a question. Instead some helpful advice with things I've
learned from trying to connect 'R' to databases using RODBC.
ROBDC is a very handy tool that, once you have everything fixed up
nicely, is a great way to have scripts run fairly autonomously, safe in the
knowledge that data isn't accidentally messed up. But I was fairly ignorant

SAS and RODBC
I am using R-2.10.1 binary from CRAN on a WinXP Pro system. I also use SAS v9.2 on the same box. I just started using the SAS ODBC driver that comes with version 9 of SAS. I have been able to set up an ODBC source for SAS datasets using the driver, and then with RODBC I am able to read a sample SAS dataset.
