I am using pypyodbc from within a specialized called Motionbuilder, and recently I've been getting this strange error:
pypyodbc.Error: (u'HY090', u'[HY090] [Microsoft][ODBC Driver Manager] Invalid string or buffer length')
It doesn't happen every time, only sometimes. Any ideas?

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 want to connnect to Oracle with R. I use RODBC package for this connection. Following is my code to connect
library(RODBC)
con <- odbcDriverConnect("Driver={Microsoft ODBC for Oracle};
CONNECTSTRING=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=123)(PORT=1521))(CONNECT_DATA=(SID=abc)));
uid=abc; pwd=abc;")
But I get the following error
1:
[RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
2:
ODBC connection failed
It's really strange, because I use direct connection, it doesn't require no TSN nor DSN. Also I succesfully connect to Oracle with the same Hostname, Port, SID, Username and password, using Oracle SQL Developer.
I am trying to connect R to an Oracle database. I am getting an error which I have already tried to trouble shoot but not able to find a solution.
I created a DSN and successfully tested the connection
I then tried to establish a connection in R.
con <- odbcConnect("DSNNAME", uid='ID', pwd='PWD')
But I receive an error.
Warning messages:
1: In RODBC::odbcDriverConnect("DSN=DSNNAME;UID=ID;PWD=PWD") :
[RODBC] ERROR: state IM014, code 0, message [Microsoft][ODBC Driver Manager]
The specified DSN contains an architecture mismatch between the Driver and Application
2: In RODBC::odbcDriverConnect("DSN=DSNNAME;UID=ID;PWD=PWD") :
ODBC connection failed
I have replaced my id and password with dummies.
Also I am using 64 bit R.
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.
Similar topic here: cannot connect to 64bit MsAccess database with 64bit Python 3.6.ODBC Driver Error
Someone asked me to create a Shiny UI to allow them to read and write from their Microsoft Access database, created with MS Office 2010.
I was following this guide to connect to the Access DB with RODBC and -- while I can open this database in Access itself -- I get the following error from R:
> channel <- odbcConnectAccess("AD_Users.accdb")
Error in odbcConnectAccess("AD_Users.accdb") : `
odbcConnectAccess is only usable with 32-bit Windows
So, I found this solution and gave it a try:
> channel <- odbcDriverConnect("AD_Users.accdb")
Warning messages:
1: In odbcDriverConnect("AD_Users.accdb") :
[RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
2: In odbcDriverConnect("AD_Users.accdb") :
[RODBC] ERROR: state 01S00, code 0, message [Microsoft][ODBC Driver Manager] Invalid connection string attribute
3: In odbcDriverConnect("AD_Users.accdb") : ODBC connection failed
> channel <- odbcDriverConnect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=AD_Users.accdb")
Warning messages:
1: In odbcDriverConnect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=AD_Users.accdb") :

2: In odbcDriverConnect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=AD_Users.accdb") :
ODBC connection failed

but as you can see, there were some pretty serious warnings. It doesn't seem to work.
Is there any other work-around?
I am using 32-bit R when I receive these warnings and even though they're warnings and not technically errors, the database connection is unsuccessful.
Update
This seems to establish a successful connection, though I've been unable to query data from it thusfar:
channel <- odbcConnectDbase("AD_Users.accdb")
I use odbcConnectAccess2007 in RODBC and don't have any issues connecting to Access databases when using 64-bit windows. However, you should check the package manual (link to pdf) to make sure that you have the appropriate drivers installed on your computer. Once you have the right drivers you should be good to go!
