I try to connect to my DB with the following request:
import pyodbc
connectionString = "driver={Adaptive Server Enterprise};database=#DB#;Server=#Server#;port=#port#;UID=#UID#;PWD=#PWD#;"
pyodbc.connect(connectionString)
However I get the following error, as if my connection string is not correct:
Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source
name not found and no default driver specified (0)
(SQLDriverConnect)')
Which is strange, since I managed to connect to my DB in R with ROBC module.
library(RODBC)
ch = odbcDriverConnect(connection = connectionString)
Any idea what is wrong with my connection string in pyodbc ?
I resolved my problem, the request is working with 32-bits python interpreter.
It appears not to be 64bits compatible.

I want to connect via pyodbc with a AS400 Database.
I configured it via the DSN syntax and it is working, but I need it DSN less.
This my current code:
connection = pyodbc.connect(
driver='{iSeries Access ODBC Driver}',
system='192.***.***.***',
uid='U******',
pwd='p0*****')
But always I got the error:
('HY000', '[HY000] [IBM][System i Access ODBC Driver]Missing system name needed for connection. (30188) (SQLDriverConnect); [HY000] [IBM][System i Access ODBC Driver]Missing system name needed for connection. (30188)')
I already tried it with the older driver "IBM i Access ODBC Driver" but same error is comming up.
Did someone also had this error?
Thanks
in my case - I just need to use capital letters for the functions variables:
connection = pyodbc.connect(
DRIVER='{iSeries Access ODBC Driver}',
SYSTEM='192.***.***.***',
UID='U******',
PWD='p0*****')
Running into an issue between using the DSN versus non DSN with the R package ODBC.
Using the DSN, I am successfully able to make a connection to the server and away the code goes. However, using the non DSN odbc connection string, I am receiving:
Error: nanodbc/nanodbc.cpp:950: IM002: [Microsoft][ODBC Driver Manager] Data >source name not found and no default driver specified
The connection appears to be syntactically correct and all of the required fields are populated according to multiple function documentations, including: https://support.rstudio.com/hc/en-us/articles/214510788-Setting-up-R-to-connect-to-SQL-Server-
odbc_con <- dbConnect(odbc::odbc(),
Driver = "SQLServer",
Server = server,
Database = test,
Uid = 'username',
Pwd = 'password',
Port = 1433)
Both server and test are defined earlier in the code.
I have tried removing the odbc:: and just using odbc().
Using semi-colons, removing caps.
Bit stuck, any suggestions?
When I switched from a Linux to a Windows box for R (note nothing else changed) I was getting
"Error: nanodbc/nanodbc.cpp:950: IM002: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"
The ODBC connection issue was fixed by changing
Driver = "ODBC Driver 17 for SQL Server"
to
Driver = "SQL Server"
Hope this saves you some time.
I'm trying to connect to SQLite through ODBC/Windows 7 with VbScript.
Using Werner's SQLite ODBC driver (http://www.ch-werner.de/sqliteodbc) to connect to a local SQLite file (c:\test.db).
Using the connection string suggest at https://www.connectionstrings.com/sqlite3-odbc-driver
Dim dbConn : Set dbConn = CreateObject("ADODB.Connection")
ConnectionString = "DRIVER=SQLite3 ODBC Driver;Database=c:\test.db;LongNames=0;Timeout=1000;NoTXN=0; SyncPragma=NORMAL;StepAPI=0;"
dbConn.open ConnectionString
I already tried reinstalling the driver and restarting the system. The error message is always there:
Error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Code: 80004005
Source: Microsoft OLE DB Provider for ODBC Drivers
Any ideas?
Quoted from the SQLite ODBC Driver developer (Christian):
Check your installation. Version 0.992 is pretty old, current version
is 0.999. If you have a 64 bit Windows, install both 64 and 32 bit
drivers. It could be that the VB stuff is still 32 bit.
The program launching the script was 32Bit (despite the OS is 64Bit). Hence the need to install both 32 and 64Bit versions of the driver.
This is my first time connecting to Vertica. I have already connected to a MySQL database sucessfully by using RODBC library.
I have the database setup in vertica and I installed the windows 64-bit ODBC driver from https://my.vertica.com/download-community-edition/
When I tried to connect to vertica using R, I get the below error:
channel = odbcDriverConnect(connection = "Server=myserver.edu;Database=mydb;User=mydb;Password=password")
Warning messages:
1: In odbcDriverConnect(connection = "Server=myserver.edu;Database=mydb;User=mydb;Password=password") :
[RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
2: In odbcDriverConnect(connection = "Server=myserver.edu;Database=mydb;User=mydb;Password=password") :
ODBC connection failed
Can someone tell me how to fix this? Or is there any other ways to connect to vertica using R?
It may not be the fastest, but I prefer to use the Vertica JDBC driver from R. Getting the ODBC drivers working is a little messy across different operating systems. If you already have a Java Runtime Environment (JRE) installed for other applications then this is fairly straightforward.
Download the Vertica JDBC drivers for your Vertica server version from the MyVertica portal. Place the driver (a .jar file) in a reasonable location for your operating system.
Install RJDBC into your workspace:
install.packages("RJDBC",dep=TRUE)
In your R script, load the RJDBC module and create an instance of the Vertica driver, adjusting the classPath argument to point to the location and filename of the driver you downloaded:
library(RJDBC)
vDriver <- JDBC(driverClass="com.vertica.jdbc.Driver", classPath="full\path\to\driver\vertica_jdbc_VERSION.jar")
Make a new connection using the driver object, substituting your connection details for the host, username and password:
vertica <- dbConnect(vDriver, "jdbc:vertica://host:5433/db", "username", "password")
Then run your SQL queries:
myframe = dbGetQuery(vertica, "select Address,City,State,ZipCode from MyTable")
You have to use double slash in the classPath arguement in JDBC function.
for example,
vDriver <- JDBC(driverClass="com.vertica.jdbc.Driver",
classPath="C:\\Program Files\\Vertica Systems\\JDBC\\vertica-jdk5-6.1.2-0.jar")
worked for me, while just copying and pasting the route failed.
I have a ASP.NET application running in VS2008 and i have ODBC connection in web.config file.
I am using 64bit Windows 7 machine.
I am trying to connect it with my MYSQL workbench but it shows me the following error:
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not
found and no default driver specified
and i am using the following connection string :
add name="dbConnectionString" connectionString="DRIVER={MySQL ODBC 5.2w Driver};server=localhost;User Id=root;database=dbname; providerName="System.Data.Odbc"
Please let me know what i am missing ?
Thanks in advance
You need to install MyODBC which is MyODBC 5.2 in your case.. Or you can use whatever MYODBC Driver is installed.. just change your DRIVER in the connection string accordingly
