I am trying to query MS SQL Server from a client with below connection string.
connStr='Driver={SQL Server};Server=Svr1;Database=testDB;User Id=DOMAIN1\User1;Password=test123;'
When I logged in to the client as a domain user, say DOMAIN1\User2 it works fine.
But in production environment, my script will be running as a service under admin account. Hence, when I try to execute the same script when logged in as local admin in same client machine, I get the below error
pyodbc.InterfaceError: ('28000', '[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication. (18452) (SQLDriverConnect); [28000] [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute (0); [28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication. (18452); [28000] [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute (0)')
When I search for this error, many of the solutions are related to password expiry cases. Is there some attribute I can add to connection string to make this query work? I tried adding IntegratedSecurity=False, but it didn't work.
I am trying to access SQL Server 14.0.2027.2 using Python PyODBC module.

I have a flask application that connects to a database on SQL Server which I am running on windows. I am using an Active Directory Service account for establishing the connection and this is how my connection string is -
# connect_db function is used to connect with the database for read and write purposes
def connect_db():
connection = pyodbc.connect(r"Driver={SQL Server Native Client 11.0};Server=server,port;Database=db;UID=domain\username;PWD=password;", autocommit=True)
return connection
Here is the error message -
pyodbc.InterfaceError: ('28000', "[28000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'domain\\username'. (18456) (SQLDriverConnect); [28000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'domain\\username'. (18456)")
Looks like the string is not escaping the \ in the UID I have tried \\ and also used r' as a raw string at the beginning of the string but it does not work.
I cannot use runas as I would like the web application to be deployed on a server in the future. When I use the same account on SSMS I am able to login successfully.
I have recently joined a new company and I have a project where I am trying to connect a Microsoft SQL Server to Power BI to automate a report and I am running into some issues. I have successfully connected the server to a SQL environment in DBeaver so I know that the host name and port number are correct.
I have not successfully created an ODBC connection for though I have tried. Using the System DSN, I have tried both the SQL Server and the ODBC Driver 17 for SQL Server and both failed connecting. With the SQL Server option, I made up a name and user the following format for the server host:port and then used my windows NT credentials on the next page and left everything else as default all the way through testing the connection. I got the below error for this one:
Microsoft SQL Server ODBC Driver Version 10.00.19041
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][DBNETLIB]Invalid connection.
TESTS FAILED!
For the ODBC Driver 17 for SQL Server option, I did the same settings with defaults and I got the below error:
Microsoft ODBC Driver for SQL Server Version 17.04.0000
Running connectivity tests...
Attempting connection
[Microsoft][ODBC Driver 17 for SQL Server]SQL Server Network Interfaces: Connection string is not valid [87].

Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.
TESTS FAILED!
When I try and import the data into Power BI using the SQL Server option, and I put the host:port into the server slot and the SQL in its place, it then ask for me to sign in. I am using my windows credentials which is accurate and so I press connect and I get the below error:
"The server name provided doesn't match the server name on the sql server ssl certificate
Please contact your administrator or see the link below for more information. Alternatively,
you could change your Connection encryption settings. Would you like to continue using an
unencrypted connection?"
I am not sure how to fix this so I can run my SQL Server script in Power BI. Does anyone have any ideas?
I am trying to connect my qt application to ms sql database. I dont know server machine's IP addres and PORT number. I allready have Data Source Name in System DSN. Here is the sample of my code :
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setDatabaseName("DRIVER={SQL Server};SERVER={serverName};DATABASE=dbname;UID=username;PWD=password;WSID=.;Trusted_connection=yes");
bool ok = db.open();
if(ok == true){
qDebug()<<"connected";
}
else{
qDebug()<<"not connected";
qDebug()<<db.lastError().text();
}
And i get this error :
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user
'xxx'. QODBC3: Unable to connect.
Any help will be appreciated.
A few things here.
First, you either use windows authentication, or you use SQL authentication. Not both.
If your connection string specifies Trusted_connection=yes, or integrated security=SSPI, then you're using windows authentication.
If your connection string specifies uid=someuser; pwd=somepassword then you're using SQL auth.
Pick one.
Now, if you're using an ODBC DSN, then the DSN already specifies the driver and server, so you don't need that in your application connection string. Instead, you just tell the application which DSN to use.
Let's say you created your DSN and called it "MySqlServer". Then your code will look like this:
db.setDatabaseName("MySqlServer");
Now, if the DSN is set up to use windows authentication, that's all you need to do. On the other hand, if it's set up to use SQL authentication, then you can take the credentials already specified in the DSN, or set a username and password in your code:
db.setUserName("myUserName");
db.setPassword("myPassword");
I'm receiving an error when I try to connect to an Azure SQL server using pyodbc.
I found the connection parameters under 'Connection strings' for ODBC in the Azure portal. I have added my IP address in the firewall settings (and waited >1 hour) but this did not resolve the problem.
import pyodbc
DRIVER = '{SQL Server}'
SERVER = 'tcp:[server name].database.windows.net'
PORT = '1433'
DATABASE = [database name]
USERNAME = [username]
PASSWORD = [password]
CONNECTION_STRING = f'DRIVER={DRIVER};PORT={PORT};SERVER={SERVER};DATABASE={DATABASE};UID={USERNAME};PWD={PASSWORD}'
cursor = pyodbc.connect(CONNECTION_STRING).cursor()
I get the following error:
ProgrammingError: ('42000', "[42000] [Microsoft][ODBC SQL Server Driver][SQL Server]

Update:
I tried connecting using Visual Studio and it prompts me to create a new firewall rule. I choose 'Add my client IP' and click 'OK'. The prompt then immediately reappears. I tried clicking it a few times and the new rules do appear in the Azure portal, but I am still not able to connect through either Visual Studio or python.
Solution:
I was using SQL authentication instead of Active Directory authentication. Solved the problem by adding AUTHENTICATION=ActiveDirectoryPassword to the connection string.
Please ensure you have added client IP to firewall.
On the Azure SQL database overview, Set server firewall.
Add client IP:
Please modify you code like this and try again:
import pyodbc
server = '<server>.database.windows.net'
database = '<database>'
username = '<username>'
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()
This code example is provided by this documen: Create code to query your SQL database.
Updates:
The error has be solved..
Finally figured it out - it turns out the problem was that Jon123 was using SQL authentication instead of Active Directory authentication.
Hope this helps.
I'm trying to run an application that I've developped recently. This one uses an ODBC connection to browse a defined database.
I'm trying to execute this app from a remote computer. Using VMWare, I've created a new Windows 7 environment and connected on. After that I've tried to create a new System DSN, but, when I set the logins that I'm using to connect on my local SQL Server 2008 I get
Connection failed: SQLState: '28000' SQL Server Error: 18452
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login
is from an untrusted domain and cannot be used with Windows
authentication.
How may I to deal with this, please?
Thanks a lot!
You will have to use SQL Server authentication to connect or add the local machine to the same domain where the server is.
