I have mssql in my windows host machine, and ubuntu in VMware. I try to connect this mssql from virtual machine with pyodbc module in python.
import pyodbc
server = '192.168.0.19'//host ip
database = 'mytestdb'
username = 'sa'
port = "1433"
password = 'mypassword'
cnxn = pyodbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER='+server+';PORT='+port+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
remote connection to my mssql instance is already enabled and I can login using same credentials so what might be problem here?
Try SERVER and PORT in one variable like this:
server = '192.168.0.19, 1433' and remove PORT.
If that doesn't work, try {SQL Server} in DRIVER.

Using the SQL Server Management Studio (SSMS) Express, I can find the database and connect without problems.
But when I use pyodbc to connect to the same server using:
import pyodbc
Server = r"xxxER\xxxSQLSERV"
db = "xxxDB"
user = "xxx"
password = "xxxx"
conn = pyodbc.connect('DRIVER={SQL Server};SERVER='+server + ';DATABASE=' + db +';UID=' + user + ';PWD=' + password)
By Using Pyhton in my local i am able to connect but when i am trying in linux server getting below error
pyodbc.OperationalError: ('HYT00', u'[HYT00] [unixODBC][Microsoft][ODBC Driver 13 for SQL Server]Login timeout expired (0) (SQLDriverConnect)')
i tried with ODBC Driver 17 for SQL Server too but facing the same issue.Can any one please suggest me on this.
Microsoft's SQL Server ODBC drivers for Linux are unable to resolve instance names. You can use the free sqlserverport module to get the corresponding port number and use that to connect.
Try removing the instance from server and set it as
Server = "xxxER"
or if you have a port number append it as
Server = "xxxER,portNo"
I have this problem and solved my problem in here.
Just add version.
conn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server + ';DATABASE=' + db +';UID=' + user + ';PWD=' + password)
If not work change version 17 to 13 if not to 11 .
List versions of ODBC.
Check your mssql network config, my problem was there.
Enable port 1433 for all IPs.
Now is working with IP and host name.
I am using SSH Tunnel with remote server port forward to localhost,1433. This pyodbc connection intermittently fails if using the approach:
cnxn = pyodbc.connect('driver={ODBC Driver 17 for SQL Server};Server=localhost, 1433;'...
Replacing localhost with 127.0.0.1 seems to be working all the time
cnxn = pyodbc.connect('driver={ODBC Driver 17 for SQL Server};Server=127.0.0.1, 1433;'
Incidentally also did same using Ruby and FreeTDS, and Localhost,1433 worked all the time.. Must be something inside the pyodbc package or their approach that sometimes drop some info to make the DBMS on server fail to respond/timeout
This worked for me:
mssql://DRIVER={ODBC Driver 17 for SQL Server};SERVER={server_address,PORT};DATABASE=<my_database>;UID=<my_username>;PWD=<my_password>
I am trying to connect to my GearHost Database in python, I followed the instructions here on GearHost. My python code looks like:
from mysql.connector import connection
server = 'den1.mssql6.gear.host'
db = 'testmenow'
user = 'testmenow'
psword = 'TEST!!'
cnxn = connection.MySQLConnection(host=server, user=usr, password=psword, database=db)
cursor = cnxn.cursor()
cnxn.close()
I get the following error:
mysql.connector.errors.InterfaceError: 2003: Can't connect to MySQL server on 'den1.mssql6.gear.host:3306' (10061 No connection could be made because the target machine actively refused it)
I have also tried to connect to GearHost through mysql workbench, as instructed in GearHost's instruction page, which also cannot connect to the database:
Connecting to MySQL server ...
Can't connect to MySQL server on 'den1.mssql6.gear.host' (10060)
This is what my GearHost shows:
Tried (unsuccessfully)
Messing with and without a port number, as mentioned here: Issue connecting to gearhost database
Trying connecting through MySQL workbench
Considering the conversation here: Cannot Connect to Database Server mysql workbench , but does not seem applicable to my circumstances.
Different SQL packages in python, including mysql-python and mysql-connector-python
Question
Am I missing something obvious that is preventing me from connecting to GearHost, either with python or mysql workbench?
UPDATE
as #SMor pointed out, I had mistaken MSSQL for MySQL - I was able to successfully connect to my database using:
import pyodbc
server = 'den1.mssql6.gear.host'
db = 'testmenow'
usr = 'testmenow'
psword = 'TEST!!'
cnxn = pyodbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER='+server+';'
'DATABASE='+db+';UID='+usr+';PWD=' + psword)
cursor = cnxn.cursor()
I'm using MySQLdb for python, and I would like to connect to a database hosted on an other PC on the same network/LAN.
I tried the followings for host:
192.168.5.37
192.168.5.37:3306
http://192.168.5.37
http://192.168.5.37:3306
None of the above work, I always get the
2005, Unknown MySQL server host ... (0)
What might be the problem?
Code:
db = MySQLdb.connect(host="192.168.5.37", user = "root" passwd = "password", db = "test1")
You can use MySQL Connector/Python, a standardized database driver for Python.
You must provide username, password, host, database name.
import mysql.connector
conn = mysql.connector.connect(user=username, password=password,
host="192.168.5.37",
database=databaseName)
conn.close()
You can download it from: https://dev.mysql.com/downloads/connector/python/
The IP you posted are local IPs
Give it a try with your external IP (for example on this website)
https://www.whatismyip.com/
If it works with the external IP, then it's maybe a misconfiguration of your firewall.
Below is the traceback. I've read all the other SO threads, googled for over two hours, and cannot figure this out. Here is what I have tried:
Both SQL Authentication and Windows Authentication versions of the connection string.
Using the SQL Server name (text) and also the IP Address of the server
Including and Excluding port 1443 (the default tcp/ip port for the SQL server)
Creating new rules in Windows Firewall to allow both inbound/outbound TCP at port 1443

here are some examples of what I've tried for the connection string:
conn = pyodbc.connect('Trusted_Connection=yes', driver = '{SQL Server}',server = '1.1.1.1,1443', database = 'master')
then
conn = pyodbc.connect(driver='{SQL Server}', server='1.1.1.1,1443', database='master', uid='xyz\login', pwd='pwd'
then I also tried both of the above with the name of the server (text) rather than the IP address. I have no idea how to get this to work at this point.
Have you confirmed you have connectivity between the servers? Try telnet -
telnet serverName 1433
If that connects then you can focus on issues with Python or the connection string.
In your connection string change it to use the PORT parameter instead of the ,1433. Something like -
SERVER=1.1.1.1;PORT=1433;
I would also say you might be better off passing the whole string. Here is what I do on Linux using FreeTDS typically -
self.db_connection = pyodbc.connect("DRIVER=FreeTDS;SERVER=1.1.1.1;PORT=1433;DATABASE=myDB;UID=myUser;PWD=myPass;TDS_Version=8.0;")
CONNECTION FROM WINDOWS TO MS SQL SERVER DATABASE:
Here you have an example I use myself to connect to MS SQL database table with a Python script:
import pyodbc
server = 'ip_database_server'
database = 'database_name'
username = 'user_name'
password = 'user_password'
driver = '{SQL Server}' # Driver you need to connect to the database
port = '1433'
cnn = pyodbc.connect('DRIVER='+driver+';PORT=port;SERVER='+server+';PORT=1443;DATABASE='+database+';UID='+username+
';PWD='+password)
cursor = cnn.cursor()
If you are trying to connect from a Windows device to the DB, go to ODBC Data Source Administrator from Windows, and check if you have installed the driver:
Where is the ODBC data source administrator in a Windows machine.
The image is in spanish, but you only have to click on 'Drivers' tab, and check if the driver is there as in the image.
CONNECTION FROM LINUX/UNIX TO MS SQL SERVER DATABASE:
If you are working in Linux/Unix, then you shoud install a ODBC manager like 'FreeTDS' and 'unixODBC'. To configure them, you have some examples in the following links:
Example: Connecting to Microsoft SQL Server from Linux/Unix
Example: Installing and Configuring ODBC
I'm using ActivePython 2.7.2.5 on Windows 7.
While trying to connect to a sql-server database with the pyodbc module using the below code, I receive the subsequent Traceback. Any ideas on what I'm doing wrong?
CODE:
import pyodbc
driver = 'SQL Server'
server = '**server-name**'
db1 = 'CorpApps'
tcon = 'yes'
uname = 'jnichol3'
pword = '**my-password**'
cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=server;DATABASE=db1;UID=uname;PWD=pword;Trusted_Connection=yes')
cursor = cnxn.cursor()
cursor.execute("select * from appaudit_q32013")
rows = cursor.fetchall()
for row in rows:
print row
TRACEBACK:
Traceback (most recent call last):
File "pyodbc_test.py", line 9, in <module>
cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=server;DATABASE=db1;UID=uname;PWD=pword;Trusted_Connection=yes')
pyodbc.Error: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. (17) (SQLDriverConnect); [01000] [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()). (53)')
You're using a connection string of 'DRIVER={SQL Server};SERVER=server;DATABASE=db1;UID=uname;PWD=pword;Trusted_Connection=yes', you're trying to connect to a server called server, a database called db1, etc. It doesn't use the variables you set before, they're not used.
It's possible to pass the connection string parameters as keyword arguments to the connect function, so you could use:
cnxn = pyodbc.connect(driver='{SQL Server}', host=server, database=db1,
trusted_connection=tcon, user=uname, password=pword)
I had the same error message and in my case the issue was the [SQL Server] drivers required TLS 1.0 which is disabled on my server. Changing to the newer version of the SNAC, SQL Server Native Client 11.0 fixed the problem.
So my connection string looks like:
cnxn = pyodbc.connect(driver='{SQL Server Native Client 11.0}',
host=server, database=db1, trusted_connection=tcon,
user=uname, password=pword)
I had faced this error due to another reason.
It was because my server had a "port" apart from the address.
I could fix that by assigning the following value to "Server" parameter of the connection string.
"...;Server=<server_name>,<port#>;..."
Note that it is a 'comma' and not 'colon'/'period'
cnxn = pyodbc.connect(driver='{SQL Server}', host=server, database=db1,
user=uname, password=pword)
print(cnxn)
I removed "Trusted_Connection" part and it worked for me.
Different security risks exist with either method. If you use Sql Server authentication you expose your userid/password in the code. But at least you process with the same credentials. If you use Windows authentication you have to insure all the possible users are setup with the right permission in the Sql server. With Sql authentication you can setup just one user but multiple people can use that one Sql User permissions wise.
I had the same issue today. I was using localhost in the connectionstring. Got rid of the issue by replacing localhost woth 'server name',. My db and application are running in the same machine.
If you don't have server name
go to Sql server management studio and execute below query, which will give you the server name.
SELECT ##SERVERNAME
The connection string look as below
conn = pyodbc.connect('Driver={SQL Server};'
'Server=myServerName;'
'Database=mydb;'
'Trusted_Connection=yes;')
