I have been trying to connect to Microsoft SQL Server. I have an ODBC connection set up and the test is successful. I am not using Windows Authentication to connect to SQL Server but it keep getting this error:
Cannot be used with Windows authentication
InterfaceError: ('28000', '[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows 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 Windows authentication. (18452); [28000] [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute (0)')
Here is my code:
import pyodbc
cnxn = pyodbc.connect(Driver='{SQL Server}',
Server='servername.abc.xyz.co.com',
username = 'user_xyz',
password = 'abcdfgh')
I am using Windows 7. Please help me debug this problem
Thanks
I was able to solve this by defining the dsn connection as below:
dsn="DRIVER={SQL
SERVER};server=ip_address_here;database=db_name_here;uid=user;pwd=password"
This worked and I was able to connect and query the sql server.
This is how I do it and it works:
import pyodbc
server_name = "server_name"
db_name = "db_name"
server = "Server="+str(server_name)
db = "Database="+str(db_name)
key = "Driver={SQL Server Native Client 11.0};"+server+";"+db+";"+"Trusted_Connection=yes;"
cnxn = pyodbc.connect(key)

Why does this workc(I get a result set back):
sql_server = 'myserver.database.windows.net'
sql_database = 'pv'
sql_username = 'sqladmin'
sql_password = 'password1'
sql_driver= '{ODBC Driver 17 for SQL Server}'
with pyodbc.connect('DRIVER='+sql_driver+';SERVER=tcp:'+sql_server+';DATABASE='+sql_database+';UID='+sql_username+';PWD='+ sql_password) as conn:
with conn.cursor() as cursor:
cursor.execute("SELECT TOP 3 SAPPHIRE_CASE_ID FROM PV_ALL_SUBMISSIONS_SL")
row = cursor.fetchone()
while row:
print (str(row[0]))
row = cursor.fetchone()
But this fails:
import pyodbc
sql_engine = sqlalchemy.create_engine(f'mssql+pyodbc://{sql_username}:{sql_password}#{sql_server}/{sql_database}?driver=ODBC+Driver+17+for+SQL+Server')
df.to_sql('PV_ALL_CLOSED_CASES_SL', con=sql_engine, if_exists='append')
Error is:

While I know one is doing a read and the other a write, my issue seems to be just establishing a connection one way vs another, when using the same connection details. It isn't an Azure firewall issue as I am able to connect and run a select statment via the first method, but when using create_engine() of sqlalchemy, it fails to make the connection - but I am pretty sure the connection string is correct.
It is the same variables for server, user name and password being used in both connections.
I think the issue is that the real password as an "#" symbol in it, and so this interferes with the latter connection string.
Thanks to #Larnu, this worked:
from sqlalchemy.engine import URL
connection_string = f"DRIVER={sql_driver};SERVER={sql_server};DATABASE={sql_database};UID={sql_username};PWD={sql_password}"
connection_url = URL.create("mssql+pyodbc", query={"odbc_connect": connection_string})
sql_engine = sqlalchemy.create_engine(connection_url)
I dont have to url encode when I use a cx_Oracle connection, but hey it works now.
I work for a nonprofit and I am trying to establish a connection from python scripts to our sql server (Microsoft SQL Server Management Studio 18) as a proof of thought and I am running into an error found below. I cannot find a solution and I have searched across StackOverflow and have tried different arrangements of codes to no success. Underneath the error is my code to connect to sql using pyodbc. I have been successful establishing a remote connection to sql on R (RODBC package) but trying to move to python. Is this a security issue on the SQL server side or am I missing a syntax? For security purposes, I filled in the username and password with fill-ins. Any help would be great!

I am connecting to a SQL Server hosted on a remote desktop using Windows server through VBA with this code:
Set objMyConn = New ADODB.Connection
Set objMyCmd = New ADODB.Command

Currently trying to use python to connect to the same SQL Server database with this code:

You should omit argument trusted_connection since you are providing UID and PWD. Trusted_connection fills UID and PWD values with your current windows user values so it is probably reserved for a local connection within the host.
I belive connection string should look like this:
'DRIVER={ODBC Driver 11 for SQL Server};'
'Server=server_name;'
'Database=db_name;'
'UID=username;'
'PWD=password;'
I want to connect my python script to SQL server:
import pyodbc
conn=pyodbc.connect('Driver=SQL_Server;Server=SQLEXP;user=44;DB=test)
I got the following error:

Server]Login failed for user. (18456) (SQLDriverConnect);
and

I have gone through other posts about this on blog but no solution found.

Connecting to Microsoft SQL server using Python
Following on from Steve-o169's comment above (below is a simple implementation):
If using SQL Server Authentication you can do this:
import pyodbc
import pandas as pd
cnxn = pyodbc.connect("Driver={SQL Server};"
"Server=yourServerName;"
"Database=yourDatebaseName;"
"uid=yourUserName;pwd=yourPassword")
query="SELECT TOP(10) * FROM yourTable"
df = pd.read_sql_query(query, cnxn)
For Windows Authentication I used the following:
import pyodbc
import pandas as pd
cnxn = pyodbc.connect("Driver={SQL Server};"
"Server=yourServerName;"
"Database=yourDatebaseName;")
query="SELECT TOP(10) * FROM yourTable"
df = pd.read_sql_query(query, cnxn)
I'm having trouble connecting to a MS SQL Server database via Python using pyODBC:
import pyodbc
conn = pyodbc.connect(('DRIVER={SQL Server};'
'SERVER=tmw-prod-lo\\SQL65;'
'DATABASE=TMWSuite;'
'UID=VENTURE\\acoop;'
'PWD=RaNdoM!'))
This results in:
InterfaceError: ('28000', "[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'VENTURE\\acoop'. (18456) (SQLDriverConnect); [28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'VENTURE\\acoop'. (18456)")
I'm pretty confident I've got all the parameters right and that I need to escape the backslashes in the server and username as above, correct? So it just looks like a permissions issue but I wanted to rule out any other issues first.
