Hello,
I'm using R 2.2.0 on a Mac and attempting to use the RODBC package to
connect to a PostgreSQL server on the local network. I can't tell
whether my problem is in R, or in ODBC setup.
I got drivers from OpenLink, created a dsn and tested it using the
iODBC application. then I load the RODBC package, use this code and
get the following error. I tried with both the odbcConnect util and
the odbcDriverConnect util. I am able to connect to the database
through other non-odbc based database programs from the Mac, so I
know it's not a Postgres setting (like no tcp/ip connections or
something).
> library(RODBC)
> channel <- odbcConnect("nfl",uid="postgres",
pwd="xxx")
Warning messages:
1: [RODBC] ERROR: Could not SQLDriverConnect
2: ODBC connection failed in: odbcDriverConnect(st, case = case,
believeNRows = believeNRows)
>
> channel2 <- odbcDriverConnect(connection="DSN=nfl, UID=postgres,
PWD=vladdy79" )
Warning messages:
1: [RODBC] ERROR: state IM002, code 0, message [iODBC][Driver Manager]
Data source name not found and no default driver specified. Driver
could not be loaded
2: ODBC connection failed in: odbcDriverConnect(connection =
"DSN=nfl, UID=postgres, PWD=xxx")
Does anyone have any suggestions?
Thanks,
Michael Greene

I've see quite a few problems which were Postgresql (sic) settings affecting the ODBC driver.> > library(RODBC) > > channel <- odbcConnect("nfl",uid="postgres", pwd="xxx") > Warning messages: > 1: [RODBC] ERROR: Could not SQLDriverConnect > 2: ODBC connection failed in: odbcDriverConnect(st, case = case, > believeNRows = believeNRows) > > > > channel2 <- odbcDriverConnect(connection="DSN=nfl, UID=postgres, > PWD=vladdy79" ) > Warning messages: > 1: [RODBC] ERROR: state IM002, code 0, message [iODBC][Driver Manager] > Data source name not found and no default driver specified.

Hi, I hope that someone can help me with the following problem with RODBC connection to a MySQL database I am running R version 2.2.0 on windows XP, and have the MySQL database registered in Windows ODBC. I have set up a web interface on my personal ISS web server using PhP to accept input values and then call Rterm with an R script to access the database and return a summary of the analysed data. This works perfectly if I run it from Rgui, or if I run Rterm from the dos prompt using the same command line arguments, but returns an RODBC error (below) when calling Rterm from the web interface 1: [RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified There appears to be some problem with recognising the database when called from the web page, even though it is not a problem at any other times. Does anyone have any suggestions as to what I can do to overcome this error Thanks for your help cheers Evan Sergeant AusVet Animal Health Services 69 Turner Cr, Orange NSW 2800 Australia Phone +61 2 6362 1598 Fax +61 2 6369 1473 Email: evan at ausvet.com.au Web site: http://www.ausvet.com.au MLA's Q Fever Register: www.qfever.org This transmission is for the intended addressee only and is confidential information.
