I am trying to use pyodbc with sql server. However I am getting the following error:
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified (0)
(SQLDriverConnect)').
This is my connection code
odbc_conn_str= 'DRIVER= {Microsoft Access Driver (*.mdb)}; DBQ=%s' %db_file
conn= pyodbc.connect(odbc_conn_str)
You are saying you are trying to connect to an SQL server but using a Microsoft Access Driver. Only use a Microsoft Access Driver if connecting to an Access Database/File.
Try the following, this is why I use to connect to a Microsoft SQL Server:
sql_connection = pyodbc.connect('DRIVER={SQL Server};SERVER=IPADDRESS\SQLSERVERINSTANCE;DATABASE=DBNAME;UID=USERNAME;PWD=PASSWORD;Trusted_Connection=no;')
Microsoft have a doc on setting up pyodbc for Microsoft SQL Server: https://learn.microsoft.com/en-us/sql/connect/python/pyodbc/python-sql-driver-pyodbc?view=sql-server-ver15

I have a python script that is using sqlAlchemy to connect to a SQL Server DB. We moved the DB from a local server in the closet to AWS.
When running from a mac, I have:
'DRIVER=/usr/local/lib/libtdsodbc.so',
and that works for both closet and AWS
on a Windows machine, for the closet the connection contained:
'DRIVER=SQL Server',
which gives the error message:
(pyodbc.Error) ('HY000', '[HY000] [Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context (0) (SQLDriverConnect); [HY000] [Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context (0)')
searching around, tells me that maybe I need a new driver, so:
https://github.com/mkleehammer/pyodbc/wiki/Connecting-to-SQL-Server-from-Windows recommends:
'DRIVER={{ODBC Driver 18 for SQL Server}}'
(Because I'm formatting into the connection string, so I need to escape the {})
gives:
sqlalchemy.exc.DBAPIError: (pyodbc.Error) ('IM012', '[IM012] [Microsoft][ODBC Driver Manager] DRIVER keyword syntax error (0) (SQLDriverConnect)')
alternatively,
'DRIVER=ODBC Driver 18 for SQL Server',
gives:
(pyodbc.InterfaceError) ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
This SQLAlchemy engine works:
Engine(mssql+pyodbc://cam-tls1:1433/services_vars?driver=SQL Server)
This one does not:
Engine(mssql+pyodbc://P-CEP-SQL:1433/services_vars?driver={ODBC Driver 18 for SQL Server})
it gives a syntax error on the DRIVER keyword...
Do I need to download a new library? or do I need to specify the driver differently?
I'm still not exactly sure how I was SUPPOSED To find this out, but this works:
'DRIVER=ODBC+Driver+17+for+SQL+Server',
even though 18 appears to be current, it doesn't work for 18. but it does work for 17.
Ran print(pyodbc.drivers()) and it printed the list of available drivers... running a SQL container in docker I'm trying to manipulate the database from a python script
connector = pyodbc.connect('Driver={ODBC Driver 18 for SQL Server};' 'Server=cbbcb967dacb;' 'Database=testdb;' 'UID=sa;' 'PWD=Working#2022' 'Trusted_Connection=yes;')
connector.execute()
cursor = connector.cursor()
cursor.execute('SELECT * FROM inventory')
for i in cursor:
print(i)
The error I get is:
pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 18 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [53]. (53) (SQLDriverConnect); [08001] [Microsoft][ODBC Driver 18 for SQL Server]Login timeout expired (0); [08001] [Microsoft][ODBC Driver 18 for SQL Server]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. (53)')
But the ODBC Driver is installed
The exception suggests a network error, cbbcb967dacb looks like the hostname of the container, you might want to try its IP address directly or localhost if you ran SQL Server in docker as per the documentation.
Are you able to telnet cbbcb967dacb 1433 ?
Based on the discussion in the comments, if your docker container is running and was started as per the MSSQL tutorial, the following connection string should work:
"DRIVER={ODBC Driver 18 for SQL Server};SERVER=localhost;UID=SA;PWD={Working#2022};DATABASE=testdb;"
This question has been asked before (see link below) but I'm still having issues even though both my Python and MS Office are 64-bit. After ensuring both are 64-bit, I tried running the following code:
conn = pyodbc.connect(r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=Q:\Data Requests\Boarding.accdb;')
but still got the following error:
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
Also of note, I am able to connect and pull data into Python from my SQL server just fine using this code:
conn = pyodbc.connect('Driver={SQL Server};'
'Server=ENTSNR;'
'Database=EMData;'
'Trusted_Connection=yes;')
PYODBC--Data source name not found and no default driver specified
I am trying to connect to SQL Server 2008 R2 using pyodbc.
This is my code snippet:
conn_strng = ['Driver={SQL Server Native Client
11},'Database=db_name','uid=user','pwd=password','trusted_source=yes']
cnxn = pyodbc.connect(';'.join(conn_strng))
I get the following error:
('IM002', '[IM002] [Microsoft] [ODBC Driver Manager] Data Source name not found or no default driver specified (0) (SQLDriverConnect)')
I have installed the SQL Server ODBC Driver 11. I am using Windows Sever 2012. I have searched in Stackoverflow and tried by changing the Driver string and other string formatting (i.e. no space etc.) but no luck.
Do I need to specify port as well?
Please help.
Ok. So I have found out a solution. Below is the correct connection string
Driver={SQL Server} #<--Note that it is different than earlier
Database=db_name
uid=user
pwd=password
trusted_source=no #<--if we set this 'yes' then it will try to connect the DB with windows login. This was causing error
I think it is better to use Driver={SQL Server} for a safer side.
I am trying to connect to a Teradata database using the following python snippet:
con = pyodbc.connect("Provider = Teradata; DBCNAME = teradata-dev,
database = mydatabase UID = myuserid, PWD = mypassword")
Database, UID, and PWD hold non-dummy values. The data source is defined in "32-bit ODBC administrator"
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)')
I have no problem connecting using R's RODBC packge. What am I doing wrong?
OS: Windows 7 professional 64 bit
Teradata Driver: 32 bit, version 14.10.00.00
Python: 32 bit, Python 2.7.10 | Anaconda 2.3.0
UPDATE:
I've tried a different connection string:
"sConn=ODBC;Driver={Teradata};DSN=teradata-dev;database=mydatabase;
UID=myusername;PWD=mypassword"
and now I get the following error:
pyodbc.Error: ('28000', '[28000] [Teradata][ODBC Teradata Driver] Not
enough information to log on (0) (SQLDriverConnect); [28000]
[Teradata][ODBC Teradata Driver] Not enough information to log on (0)')
UPDATE #2:
I got it to work correctly by using the DSN directly.
"DSN = dsninODBC;USN = myusername;PWD = mypassword"
