I am trying to connect to azure sql database. But somehow I keep getting the following error:

pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]Client unable to establish connection (0) (SQLDriverConnect)')

I have ODBC Driver 17 installed.

here is my code: 

import pyodbc
server = 'mftaccountinghost.database.windows.net'
database = 'mft_accounting'
username = 'localhost'
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()
cursor.execute("select * from dbo.expense_zoho")
row = cursor.fetchone()
while row:
    print (str(row[0]) + " " + str(row[1]))
    row = cursor.fetchone()

Here is my connection string on Azure SQL Database Connection String

Does anyone have an idea why the error pops up?

Thanks.

did you enable connections from wherever you are connecting on the Azure SQL firewall? - 4c74356b41
Does the connection string in the screenshot works for you? If so, then why aren't you including the other connection string parameters like Encrypt=yes when you build it in your Python code? - Gord Thompson
@4c74356b41 yes, I did - Nikolay Oleynikov
@GordThompson I used the whole string, it didn’t work either - Nikolay Oleynikov

Please make sure you have created a SQL login with permission to connect to the database. You can try creating a contained database user as shown below and used that contained login to connect to the database. Have you created that login named localhost?

CREATE USER yourlogin WITH PASSWORD = 'Yh-EhGFjh+';
GO
exec sp_addRoleMember 'db_datareader', 'yourlogin'; 
GO

Make sure you have created a firewall rule as explained on this documentation and the server name and database names are correct (you have not misspelled them).

Try to connect using database tools like SSMS.

Make sure you have install the right Python SQL Driver.

Please reference this tutorial: Quickstart: Use Python to query an Azure SQL database.

Here's my example pyodbc code and it works well in my window.

import pyodbc
server = 'sqlserverleon.database.windows.net'
database = 'Mydatabase'
username ='ServerAdmin'
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()
cursor.execute("SELECT * FROM TEST6")
row = cursor.fetchone()
while row:
    print (str(row[0]) + " " + str(row[1]))
    row = cursor.fetchone()

Hope this helps.
