I have been running Python script using my desktop at work that successfully connects to a remote desktop server and outputs data in SQL via pyodbc.connect.
I am looking to migrate this code to a separate remote desktop PC recently installed at work and I get the following error:
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
The code I am using is:
cnxn = pyodbc.connect("Driver={SQL Server Native Client 11.0};"
"Server=AUBAMTRAS01-DEV;"
"Database=ForwardTrading;"
"Username=xxxxxxxx;"
"Password=yyyyyyyy;"
"Trusted_Connection=yes;")
cursor = cnxn.cursor()
cursor.execute('SELECT distinct(Commodity) from ForwardCurvesOilAndGas')
for row in cursor:
print('row = %r' % (row,))
Data source name not found and no default driver specified
This means you need to install the SQLDriverConnect driver on your second machine.
SOLVED - Driver required was 'SQL Server' not 'SQL Server Native Client 11.0'

Recently I'm trying to connect to a SQL Server though pyodbc but I'm having some troubles with the connection string. I already tried as suggested on this previous question: Pyodbc error Data source name not found and no default driver specified paradox, creating a .dsn file and trying to implement the procedure's output on the string, but stil get the same error message: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')
This is what I'm doing so far:
conn = pyodbc.connect('DRIVER={ODBC Driver 13 for SQL Server};
'WSID={BRRIO-xxxx};'
'APP={Microsoft® Windows® Operating System};'
'Trusted_Connection=Yes;'
'SERVER=BRRIO-xxxx\xxx;'
'Database=xxx_Data;'
'UID="xxxx";'
'PWD="xxxx";'
)
and this is what my .dsn file looks like:
DRIVER={ODBC Driver 13 for SQL Server};
WSID={BRRIO-xxxx};
APP={Microsoft® Windows® Operating System};
Trusted_Connection=Yes;
SERVER=BRRIO-xxxx\xxx
Any help is really appreciated!
For anyone who's having some troubles with this, I found the solution following the steps here: https://www.sqlserverlogexplorer.com/database-does-not-exist-access-denied/
Basically for me it was a firewall problem, where the port 1433 was blocked. Also, make sure you are using the correct driver for you case (pyodbc.drivers(), as suggested by #Gord Thompson) and check for remote server connections on yours SQL Server (SQL Server Management Studio > Go to SQL Server instance property > Connections > check Allow remote connection to this server).
I'm trying to connect to an Azure SQL Server instance from a laptop with Jupyter installed. Fairly new at this but having issues which are probably simple to resolve.
I've installed 64bit Python 3.7, Jupyter and AMD64 v17 pyodbc via pip. However when I'm trying to connect via Jupyter I just get either connection or driver issues, not quite sure.
Below is the code I'm trying to run to connect and return a simple top 10 rows query.
import pyodbc
server = 'xxxsqlserver.database.windows.net'
database = 'xxx.dbo.table'
username = 'user'
password = 'password'
driver='{ODBC Driver 17 for SQL Server}'
cnxn = pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
cursor.execute("SELECT TOP 10 * FROM xxx.dbo.table")
row = cursor.fetchone()
while row:
print (str(row[0]) + " " + str(row[1]))
row = cursor.fetchone()
Below is the error message I get:
InterfaceError Traceback (most recent call
last) in
5 password = 'password'
6 driver='{ODBC Driver 17 for SQL Server}'
----> 7 cnxn = pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+
password)
8 cursor = cnxn.cursor()
9 cursor.execute("SELECT TOP 10 * FROM xxx.dbo.table")
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified (0)
(SQLDriverConnect)')
If I change the driver to 13 I get a different error
InterfaceError: ('28000', '[28000] [Microsoft][ODBC Driver 13 for SQL
Server][SQL Server]Login failed for user \'user\'. (18456)

Feels like the driver isn't doing something quite right or I've got a misalignment somewhere. Note I didn't install any version 13 drivers but do have SSMS installed which put some in, and this connects to the Azure platform just fine.
Any ideas?
Thanks.
Hi there from the looks of things, this may be because your ODBC drivers are not installed properly. It is mostly likely because your are not formatting the string properly. So, here is a comprehensive list of what you need to do:
Install the correct ODBC drivers to connect with SQLServer
This depends on your operating system of course, if you have MacOS, you can go ahead and install it using homebrew like so:
brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
brew install msodbcsql17 mssql-tools
If you do not know what homebrew is, please take a look at the homebrew official website. If this is not your operating system, then take a look at OS specific instructions in this guide.
Once you have done this, make sure to follow the instructions at the end of the installation, where they tell you what changes you need to make to your dotfiles in order to get ODBC working properly.
Make sure to get the connection string properly. The connection string is located in the "Connection Strings" section of your SQLServer database, and under ODBC:
Once you have the connection string, use fstrings or the .format() function on a string to replace the section of the string that says Pwd={your_password_here}
This should do the trick. However, if it does not then you need to check whether you have the correct username, password and table. If you are sure that they are correct, then you might want to contact Support, since they might have changed the requirements for drivers to be a specific version for your database.
I've also encountered the same error while connecting to Azure SQL database.
The error disappeared once the driver name was changed from DRIVER={ODBC Driver 17 for SQL Server} to DRIVER={SQL Server}, for example:
import pyodbc
server = '<sql-server-name>.database.windows.net'
database = '<database>'
username = '<username>'
password = '<password>'
driver='{SQL Server}'
cnxn = pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
cursor.execute("SELECT TOP 10 * FROM dbo.allOrders")
row = cursor.fetchone()
while row:
print (str(row[0]) + " " + str(row[1]))
row = cursor.fetchone()
I'm trying to connect to an oracle database with Pyodbc:
pyodbc.connect('{Microsoft ODBC for Oracle};Server=serverxzy.com:1234;Uid=myusername;Pwd=pass123')
I get the following error message:
pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
Any suggestions how to fix it would be appreciated. I'm specifically interested in getting pyodbc to work and NOT cx_Oracle.
You have to use the proprietary library for Oracle, cx_Oracle, and you must have the Oracle client and SDK installed.
Once this is all set up you can simply:
import cx_Oracle
conn_str = 'USER/PASS#HOSTNAME:PORT/ALIAS'
conn = cx_Oracle.connect(conn_str)
Then you can create a cursor with the conn object:
c = conn.cursor()
And then you can execute SQL:
c.execute(SQL)
Consider specifying the DRIVER in connection string:
pyodbc.connect('DRIVER={Microsoft ODBC for Oracle};Server=serverxzy.com:1234;
Uid=myusername;Pwd=pass123')
I'm trying to do access the remote MS-SQL database from my OS X machine, with help of pyodbc and python. When I try to execute, it's showing an error like this
Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')
The code I've written is:
import pyodbc
def createdatabase():
driver = 'SQL Server'
server = '00000000'
db1 = 'Vodafone'
tcon = 'yes'
uname = 'user'
pword = 'pwd'
cnxn = pyodbc.connect(driver='{SQL Server}', host=server,database=db1,trusted_connection=tcon, user=uname, password=pword)
cursor = cnxn.cursor()
This may not be your only problem, but the pyodbc.connect() string needs to be formed with semicolons like this:
DRIVER={FreeTDS};SERVER=yoursqlserver.com;PORT=1433;DATABASE=yourdb;UID=youruser;PWD=yourpass;TDS_Version=7.2;
You'll also have to read up on setting up FreeTDS and unixODBC from a Mac. If you're specifying SQL Server instead of FreeTDS, I'm guessing you haven't set up your configuration in freetds.conf, odbc.ini and odbcinst.ini, which are required for connecting to SQL Server from non-Windows machines.
I've read all the faq pages from the python odbc library as well as other examples and managed to connect to the DSN, using the following code:
cnxn = pyodbc.connect("DSN=DSNNAME")
cursor = cnxn.cursor()
cursor.tables()
rows = cursor.fetchall()
for row in rows:
print row.table_name
but for everything else I keep getting this error:
Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
I know that I can pull up my data using Microsoft Access by going through the following steps: Creating a new database, clicking the external data tab, Click More and select ODBC database, use the Link to the data source by creating a linked table, in the Select data source window choosing Machine Data source and select NAME2 which has a System type, press okay and choose the table acr.Table_one_hh, then select the fields in the table that I want to look at like City, State, Country, Region, etc. When I hover over the table name it shows the DSN name, Description, Trusted Connection = Yes, APP, Database name and the table name.
I've attempted two methods, first
cnxn = pyodbc.connect('DRIVER={SQL Server Native Client 10.0};SERVER=mycomputername;DATABASE=mydatabase;Trusted_Connection=yes;')
cursor = cnxn.cursor()
which gives an error:
Error: ('08001', '[08001] [Microsoft][SQL Server Native Client 10.0]Named Pipes Provider: Could not open a connection to SQL Server [2]. (2) (SQLDriverConnect); [HYT00] [Microsoft][SQL Server Native Client 10.0]Login timeout expired (0); [08001] [Microsoft][SQL Server Native Client 10.0]A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online. (2)')
I tried
cnxn = pyodbc.connect("DSN=DSNNAME, DATABASE=mydatabase")
cursor = cnxn.cursor()
cursor.execute("""SELECT 1 AS "test column1" from acr.Table_one_hh""")
cursor.tables()
rows = cursor.fetchall()
for row in rows:
print row.table_name
which gave an error
Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
I managed to solve my issue. My code did not really change.
cnxn = pyodbc.connect("DSN=BCTHEAT")
cursor = cnxn.cursor()
cursor.execute("select * from acr.Table_one_hh")
row = cursor.fetchall()
then I wrote the results into a csv file.
