Is there a way to connect to MySQL database with Windows Authentication in Python? It is enabled on MySQL server, I login into it with Microsoft MySQL Server Management Studio no problem. However, usual setup:
import MySQLdb
db = MySQLdb.connect(host="sampleserver\\demo",
db="sample")
doesnt seem to work. In fact, host is not even recognized. Our DBA didnt give me a endpoint aside from that host. It works for the Management Studio.

As per suggestion in the answer, tried connecting with the connection string method with pyodbc library.
import pyodbc
cnxn = pyodbc.connect("DRIVER={SQL Server};"
"SERVER=server_name\\demo;"
"DATABASE=sample;"
"UID=auth_windows")
Double backslash, I'm escaping the backsalsh in the server name
Getting fairly long error message:
Error: ('28000', "[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'auth_windows'. (18456) (SQLDriverConnect);
[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'auth_windows'. (18456)")
When I tried to add IntegratedSecurity=yes, I also get:
[01S00] [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute (0)
This is the connection string you need to use:
Server=myServerAddress;Database=myDataBase;IntegratedSecurity=yes;Uid=auth_windows;
This option is available from Connector/NET version 6.4.4, but please note that is requires the Windows Native Authentication Plugin must to be installed.
Based on Jaco's answer but pyodbc library requires slightly different string, or it will produce unrecognized attribute error:
Server=myServerAddress;Database=myDataBase;Trusted_Connection=yes;Uid=auth_window;

I am receiving a very common error while trying to connect Microsoft SQL Server using pyodbc. I've tried the solutions suggested here before, but none of them solved my problem.
import pyodbc
conn = pyodbc.connect('Driver={SQL Server};'
'Server= server_name;'
'Database= database_name;'
'UID= user_id;'
'PWD= password;')
InterfaceError: ('28000', "[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]
Login failed for user ' '. (18456) (SQLDriverConnect); [28000] [Microsoft][ODBC SQL Server Driver]
[SQL Server]Login failed for user ' '. (18456)")
When I connect the database via Microsoft SQL Server Management Studio 18 app, below is how I connect. I copy and paste server name, login, and password information to my Python code as shown above. My OS is Windows 10. When I call select ##version, I get Microsoft SQL Server 2014 (SP3-GDR) (KB4583463)...
Admittedly my python skills are not the best but I'm suspicious of all the single quotes in your connection string.
In the error message Login failed for user ' ' is that blank value for the use what you actually see or have you stripped that out? If that's what you actually see then I think your connection string is malformed.
Refer to the sample here for how to build out a connection string.
I am looking for a solution for inserting CSV file to SQL Server and for inserting data to SQL Server I faced with below error.
I read lot about this issue and did several changes but nothing happened and still I can't import csv to relative table. I can't understand why this error also happened?
Microsoft SQL has been installed on my local computer:
conn = pyodbc.connect('Driver=SQL Server; Server=ServerName\MSSQLSERVER; Database=DBName;Trusted_Connection=yes ; UID=Administrator')
Error:
pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][DBMSLPCN]Invalid connection. (14) (SQLDriverConnect); [08001] [Microsoft][ODBC SQL Server
Driver][DBMSLPCN]ConnectionOpen (ParseConnectParams()). (14)')
For anyone who faced with above problem,If you want to connect to sql server with SQL Authentication, the format will be changed as below:
pyodbc.connect('Driver={SQL Server}; Server=ServerName;
Database=DBName; UID=UserName; PWD= {Password};')
I'm unable to connect to SQL-server using pyodbc module in python, my connection string is like this.
pyodbc.connect(driver=driv,host=server,database=db,trusted_connection="yes",user=user,password=pasw)
I'm hitting an error like this
Error: ('28000', '[28000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (18452) (SQLDriverConnect); [28000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (18452)')
The version of sql server I'm having is,
Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64) Oct 19 2012
13:38:57 Copyright (c) Microsoft Corporation Standard Edition
(64-bit) on Windows NT 6.2 (Build 9200: )
which I had got by running SELECT ##VERSION query.
I had used SQL Server Native Client 11.0 as driver. One thing I noticed is that in sql server management studio I used SQL server authentication instead of windows authentication. But here, by the error message it seems it is trying windows authentication instead. Is there any way I can use SQL server authentication instead of windows authentication here? I guess that would solve this problem.
With the more recent versions of Microsoft's ODBC driver for SQL Server, Trusted_Connection=yes takes precedence, so the connection will attempt to use Windows authentication even if UID= and PWD= are supplied. If you want to use SQL Server authentication then simply use Trusted_Connection=no and supply the UID= and PWD= for the SQL Server login.
You are trying to connect to it from another domain controller then you will get this error when IntegratedSecurity = True, by default
Integrated security means simply - use your windows credentials for login verification to SQL Server. So, if you are logged in to a different domain controller then it will fail. In the case where you are on two different domain controllers then you have no choice but to use
IntegratedSecurity = false
So you can try this:
conn = pyodbc.connect(
r'DRIVER={SQL Server Native Client 11.0};
SERVER=localhost;
Integrated_Security=false;
Trusted_Connection=yes;
UID=user;
PWD=password;
DATABASE= db')
I used the pyodbc and pypyodbc python package to connect to SQL server.
Drivers used anyone of these ['SQL Server', 'SQL Server Native Client 10.0', 'ODBC Driver 11 for SQL Server', 'ODBC Driver 13 for SQL Server'].
connection string :
connection = pyodbc.connect('DRIVER={SQL Server};'
'Server=aaa.database.windows.net;'
'DATABASE=DB_NAME;'
'UID=User_name;'
'PWD=password')
now I am getting error message like
DatabaseError: (u'28000', u"[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user
But I can connect to the server through the SQL server management studio.
its on SQL Server Authentication, Not Windows Authentication.
Is this about python package and driver issue or DB issue??? how to solve?
You can add Trusted_Connection=NO; in your connection string after the password
I see you have no port defined in your script.
The general way to connect to a server using pyodbc ${DBName} ${DBUser} ${DBPass} ${DBHost} ${DBPort}, where DBName is your database name, DBUser is the username used to connect to it, DBPass is the password, DBHost is the URL of your database, and DBPort is the port you use to connect to your DB.
I use MS SQL so my port is 1433, yours might be different.
I've had this issue just today, and that fixed it.
The problem is not driver issue, you can see the error message is DatabaseError: Login failed for user, it means this problem occurs if the user tries to log in with credentials that cannot be validated. I suspect you are login with your windows Authentication, if so, use Trusted_Connection=yes instead:
connection = pyodbc.connect('DRIVER={SQL Server};Server=aaa.database.windows.net;DATABASE=DB_NAME;Trusted_Connection=yes')
For more details, please refer to my old answer about the difference of SQL Server Authentication modes.
I think problem because of driver definition in your connection string. You may try with below.
connection = pyodbc.connect('DRIVER={SQL Server Native Client 10.0}; Server=aaa.database.windows.net; DATABASE=DB_NAME; UID=User_name; PWD=password')
I applied your connection string and updated it with my server connections details and it worked fine.
Are you sure your are passing correct user name and password ?
Login failed implies connection was established successfully, but authentication didn't pass.
I'm having issues connecting to a working SQL\Express database instance using Robot Framework's DatabaseLibrary.
If I use either Connect To Database with previously defined variables or Connect To Database Using Custom Params with a connection string, I get the following results:
pyodbc: ('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)')
pymssql:: InterfaceError: Connection to the database failed for an unknown reason.
The connection string I'm using is the following: 'DRIVER={SQL Server};SERVER=localhost\SQLExpress;UID=sa;PWD=mypass;DATABASE=MyDb'
I copied several examples from guides and tutorials and all of them yield the same result, so my guess is that there is something wrong on my end, but I just can't figure out what. I can access the database using the Microsoft SQL Server Management Studio just fine, so the database is running.
Any guidance will be greatly appreciated!
I was able to connect using #Goralight approach: Connect To Database Using Custom Params pymssql ${DBConnect} where ${DBConnect} contained database, user, Password, host and port
