I am trying to connect to my database on MS SQL Server 2016 using pyodbc via the below python script from my laptop (on Windows 10) and planning to have the code deployed in a Linux RHEL 6.4 server.
conn=pyodbc.connect('Driver={SQL Server};'
'Server=DB_Instance;'
'Database=DB_Name;'
'UID=user_name;'
'PWD=password;'
'Trusted_Connection=no;');
At my laptop, SQL Server (version: 10.00.17763.01) and SQL Server Native Client 11.0 (version: 2011.110.7493.04) are already available.
While executing the python script from my laptop, I am getting the below error message.
pyodbc.operationalError: ('08001', '[08001] [Microsoft] [ODBC SQL Server Driver][DBNETLIB]SSL Security error (18) (SQLDriverConnect); [08001] [Microsoft] [ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (SECDoClientHandshake()). (772)')
As per the organization standard, TLS 1.0 is disabled on the windows server where the SQL Server is installed in the network. Since I am accessing the database via python script, we cannot temporarily enable TLS 1.0. I am looking for a direction. Any help is greatly appreciated!!
Gord Thompson pointed Guna in the right direction in the comments:
Can you try using ODBC Driver 17 for SQL Server and see if that works for you?
– Gord Thompson
Guna said that this worked:
I was facing different set of errors. While adding the port number in addition to the server name, the problem got resolved. The ODBC Driver name also needs to be updated. conn=pyodbc.connect('Driver={ODBC Driver 17 for SQL Server};' 'Server=DB_Instance,port;' 'Database=DB_Name;' 'UID=user_name;' 'PWD=password;' 'Trusted_Connection=no;');

PROBLEM: -
When trying to perform password change for MSSQL server, you get the following error message:-SSL Security error
SOLUTION: -
It's likely an issue with the version of the SQL Native Client driver being used to establish the connection.
Please Download & install "ODBC Driver 13 for SQL Server" on the CPM servers.
https://www.microsoft.com/en-us/download/confirmation.aspx?id=50420
Download 32 bit driver : x86\msodbcsql.msi
Install as usual
Edit MSSQL Platforms to change the connection command from
Driver={SQL Server};Server=%ADDRESS%;Database=%DATABASE%;Uid=%USER%;Pwd=%LOGONPASSWORD%;
to
Driver={ODBC Driver 13 for SQL Server};Server=%ADDRESS%;Database=%DATABASE%;Uid=%USER%;Pwd=%LOGONPASSWORD%;
Restart the CPM service to pick up the platform changes & retest

I am getting a strange error with Python condo environments and PyODBC. I have multiple Conda environments, I am able to connect from one of the environment (from a Linux machine) to SQL Server hosted on Azure but not from the other one. Both Python environments have version 3.7.7 of Python and version 4.0.0 of Pyodbc. Code is exactly the same and connection string uses SQL Server 17 driver.
conn_str='DRIVER={ODBC Driver 17 for SQL Server};SERVER=' +server+';Authentication=ActiveDirectoryPassword;DATABASE='+database+';UID='+self.user_name+';PWD='+self.password
Error is :
pyodbc.OperationalError: ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0) (SQLDriverConnect)')
As you can see above, the issue might be DNS-related. In the
connection string, try using an IP address instead of the hostname,
or check your DNS setup.
Try downgrade to ODBC driver 13 and have a try. For that version 17
needs to be uninstalled.
Try using connect from SQL Authentication instead of Active Directory
Password.
The SQL Server ODBC drivers for Linux from Microsoft are unable to determine instance names.
I am trying to connect to a database, from a Windows 10, that is on another pc in the same local network using the pyodbc module. The external pc is a Windows Server 2003 and it has a database Microsoft SQL Server 2005. I am not sure how the connection string has to be, I have tried with the following code:
import pyodbc
DRIVER = "{ODBC Driver 11 for SQL Server}" # supports SQL Server 2005 through 2014
SERVER = "192.168.100.101" # the ip of the windows server 2003
PORT = "1433" # I am not sure if this parameter is needed
DATABASE = "database_name" # name of the database
USER = "user"
PASS = "psw"
string_connection = f"DRIVER={DRIVER};SERVER={SERVER};PORT={PORT};DATABASE={DATABASE};UID={USER};PWD={PASS}"
cnxn = pyodbc.connect(string_connection)
cursor = cnxn.cursor()
cursor.close()
cnxn.close()
But when I run the code above I get the following error:
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
Data source name not found and no default driver specified
This error message indicates the driver specified in the connection string is not installed on the client machine. Run odbcad32.exe on the Win10 machine and click the drivers tab to view the list of installed ODBC drivers.
To remediate, you can either change the connection string to use an already installed SQL Server ODBC driver, or install the ODBC Driver 11 for SQL Server from here.
Be aware that Windows Server 2003 and SQL Server 2005 have been out of support for several years. The oldest support Windows server version is 2012 and SQL 2012 is the oldest SQL version as of this writing. I suggest you migrate to newer versions.
I am trying to get a python script to deploy to Cloud Foundry which uses pyobdc to connect to sql server and execute commands. My pyobdc connection statement looks like so:
warehouse_connection = pyodbc.connect(f'Driver={DRIVER}'
f';Server={SERVER}'
f';Database={DATABASE}'
f';UID={USERNAME}'
f';PWD={PASSWORD}'
';Trusted_Connection=no')
warehouse_cursor = warehouse_connection.cursor()
The driver I am using is ODBC Driver 17 for SQL Server and I have the odbcinst.ini file which looks like so:
[ODBC Driver 17 for SQL Server]
Description=Microsoft ODBC Driver 17 for SQL Server
Driver=/home/vcap/deps/0/apt/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.6.so.1.1
UsageCount=1
My script works fine on my local machine so I know the access account info is up to date and I have other scripts that use that driver which work fine, but when I try to deploy to Cloud Foundry I get the following error:
pyodbc.OperationalError: ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout
expired (0) (SQLDriverConnect)')
I tried changing the trusted connection variable, made sure my apt/environment was up to date, I am not sure what I am missing. Is there in issue with pyodbc in Cloud Foundry or am I getting something wrong?
Thanks.
In case anyone comes back an looks at this, it turns out all we needed to do was open up firewall access from that cloud foundry space and then it worked. Posted this a while ago and realized I should probably answer it.
I had written code to connect to a DB2 server using Python that was working fine until my company had me upgrade the IBM DB2 Driver to 11.5. Now, its no longer working and I'm getting the following error message:
SQLCODE=-30082n: [IBM][CLI Driver] SQL30082N Security processing failed with reason "15" ("PROCESSING FAILURE"). SQLSTATE=08001
I verified that I have the right password. Also, I confirmed that I still have access to the Database by going through the ODBC Manager in Windows and testing a connection that way. I've checked several pages here on Stackoverflow and other sites and nothing seems to work. Most of the issues people are having on this site involve different error messages.
Here is the original code using the ibm_db module:
import ibm_db
import ibm_db_dbi
con = ibm_db_dbi.Connection(ibm_db.connect("ABC1011","rsmith","Passw123"))
When that stopped working i tried connecting using pyodbc as a connection:
import pyodbc
cnxn = pyodbc.connect('DRIVER={IBM DB2 ODBC DRIVER - DB2COPY2};Database=ABC1011;UID=rsmith; PWD=Passw123')
Again, I already verified in the ODBC Datasource Administrator (64-bit) that I am using the correct password, I have the correct database, and that I am using the correct driver's name. Does anyone know what else I may need to include to get a connection to work?
Thank you.
I am having issues connecting to an Azure database from a Virtual Machine running Ubuntu 16.04. This VM is in Google cloud. I get the following error
pypyodbc.Error: (u'IM002', u'[IM002] [unixODBC][Driver Manager]Data source
name
not found, and no default driver specified')
This code works fine locally on my PC in a Jupyter notebook. I have added the Google Cloud VM's IP address to the let it through the Azure firewall- so that doesn't appear to be the cause of the error. I have observed that I can replicate the original error message in Jupyter notebook if I change the driver "SQL Server Native Client" from 11.0 to 13.0
This all points to driver issues. A similar issue has been discussed here
With the problem being linked to "not defining that driver in the "/etc/odbcinst.ini" file."
My odbcinst.ini file contains the following information:
[ODBC Driver 13 for SQL Server]
Description=Microsoft ODBC Driver 13 for SQL Server
Driver=/opt/microsoft/msodbcsql/lib64/libmsodbcsql-13.1.so.8.0
UsageCount=1
My odbc.ini file contains no information.
If I change my connection string in my code to "Driver={SQL Server Native Client 13.0" I get the same error. My other thought was to run with a version 11 of the driver. However there doesn't appear to be one for Ubuntu (only SUSE & RedHat Linux).I am new to this subject area- so feeling stuck. Any suggestions on a next logical step to resolve the connection issue.
Regards
Mike
