Prior to upgrading to Windows 10, I was using RODBC to establish a connection within RStudio to a MS Access database.
After upgrading to Windows 10, my workflow is halted when I try to make the same connection to the same MS Access database.
db <- "//svr/userdatabases/database.accdb"
Make a connection to the database
con2 <- odbcConnectAccess2007(db)
[RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifiedODBC connection failed>
I have confirmed that the database is located in the correct path (db).
Several sources have suggested that there is an issue with LD_LIBRARY_PATH, but I do not know how to implement the solutions discussed in these threads:
https://support.rstudio.com/hc/en-us/community/posts/200654626-odbcDriverConnect-works-in-R-but-not-RStudio
https://support.rstudio.com/hc/en-us/community/posts/211021467-Can-t-connect-to-SQL-database-using-RODBC-through-Rstudio-but-can-using-R-in-shell-
How do I implement the solution described in the second link? Specifically, how do I I had create a file "~/.Renviron" and add the following line:
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/nz/lib64/
According to that link, my issue is the ld library path within my rsession is not the same as my bash.
You might be missing the driver for the correct bit version of your database for RStudio to make the system connection. If your system connection works in R, but not R Studio, installing the correct driver from https://www.microsoft.com/en-us/download/confirmation.aspx?id=23734 might solve your issue.

I've been trying to connect RStudio to a DB2 database and have been receiving the following error
rror: nanodbc/nanodbc.cpp:950: IM003: Specified driver could not be loaded due to system error 1114:
A dynamic link library (DLL) initialization routine failed.
(IBM DB2 ODBC DRIVER - DB2COPY1, C:\PROGRA~1\IBM\SQLLIB\BIN\DB2CLIO.DLL).
I've been using this code
connection<-DBI::dbConnect(odbc::odbc(),Driver="IBM DB2 ODBC DRIVER - DB2COPY1",
Server = "NRDCWIP6",uid="nxxx",pwd="Wxxx")
which has been working well for a different database (SQL server). I'm working in Windows 10 and don't have a lot of information about the database itself since it's managed by an IT group that's quite busy. I'm still quite new to connecting R to databases as well. I do know that the platform for the DSN is 32-bit, but when I look under the User DSN tab, it is listed as 32/64 bit.
I know 1114 is a rather well known error, but I'm not sure where the problem is and I've tried numerous variations of this code. Anything will help!
Here may be the answer for this situation:
Specified driver could not be loaded due to system error 1114

Here is the key note from above:
Resolving The Problem
Launch the odbcad32.exe from the Windows/SysWOW64/ folder and ensure that you have the current driver for the database version you are connecting to, specified in the Data Source that is being used in the map
Hope this helps.
I am using an R Script which connects to a local Access database. For that, I used the 'odbc' package in R and created an odbc Driver in Windows. It works well on my machine.
The issue I have is, that it can't connect to the database when running the script on a foreign computer with different language settings than English. Both machines are running Windows 64-bit with Access and R on 64-bit. Running following Code:
library(odbc)
con <- dbConnect(odbc::odbc(), "AccessDB")
results in following error message:
Error in connection_info(ptr) : nanodbc/nanodbc.cpp:1072:
I didn't find a solution yet, I am thinking of using another database.
I received the same error today on a setup that usually works. After downgrading the odbc-package to 1.1.6, it works fine again.
I try to do a simple connect to an Oracle database via DBI and ROracle package following instructions from R to Oracle Database Connectivity: Use ROracle for both Performance and Scalability.
When I test the connection via Windows7 > ODBC Data Source Administrator (32bit), the connection is successful. It uses the installed Oracle client OraClient11g_home1 which resides in C:\oracle\Client112_32. ORACLE_HOME environment variable is set to C:\oracle\Client112_32.
I am guessing it may be connected to some 32bit/64bit issue? But even after quite some research I did not find any solution. I also tried running the same in R 32bit but fails as well. BTW, the connection via SQL Developer is also successful.
drv <- DBI::dbDriver("Oracle")
#>Error: Couldn't find driver Oracle. Looked in:
#>* global namespace
#>* in package called Oracle
#>* in package called ROracle
I've had this issue as well. I found that loading the ROracle library beforehand fixes the problem.
library("ROracle")
drv <- DBI::dbDriver("Oracle")
I don't know why though.
Building on user11227405 answer: it is actually enough to load ROracle without attaching it on the search path; library() does both instead:
loadNamespace("ROracle")
drv <- DBI::dbDriver("Oracle")
that might be preferred e.g. in packages, where changing the search path should be avoided
I have an old software running on XP. When I run it on another pc the following error arises
odbc driver manager, data source name not found and no default driver specified.
How do I get around this problem?
Note: on the old system I checked in administrative tools in data source is has foxpro drivers.
Technically that message looks like a failed attempt to create an ODBC connection via DSN ("Data Source Name") which does not exist. VFP Command Window example:
? SQLCONNECT("DsnDoesNotExist")
AERROR(laErrors)
DISPLAY MEMORY LIKE laErrors
If the original maintainer of your software did not provide any "setup" documentation, you can find the Name of the required Data Source in the source code, either as code line(s) using Vfp's SqlConnect()function, or as a "Connection" object stored in a Vfp myDatabase.DBC
If you have not got the source code, you can try to find the related "User DSN" or "System DSN" in the Windows "ODBC Data Source Administrator" of the old PC.
That DSN would contain the required connection string including driver info, e.g. "PostgreSQL" or "MS SQL Native Client", etc.
If the new system is a 64bit version, you'd need to use the 32bit version of the administration tool (usually C:\WINDOWS\SysWOW64\odbcad32.exe) in order to recreate the DSN there.
FWIW, Vfp itself does not necessarily need a "DSN" for ODBC connections - if you've got the source code, see the SqlStringConnect() function in the VFP documentation or try a web search
Hi I was trying to connect to a table in MS-Access(2007) with perl. but each time I execute, I receive an error an failed: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (SQL-IM002).
Recently when I tried double clicking on the Driver in ODBC datasource administrator I found the error The setup routines for the microsoft access driver(*.mdb,*.accdb) ODBC driver could not be found. Please reinstall the driver. I tried installing drivers but still I get the same error.
Please guide me with my problem.
In a 64-bit system ,by default all the datas are linked on to the 32-bit. so we need to explicitly move datas from 64 to 32-bit.
