We can search odbc in our local program and check for version of odbc. In my case I have version 17 and 11 so. I have used 17 in connection string
'DRIVER={ODBC Driver 17 for SQL Server}'

I've met same problem and fixed it changing connection string like below. Write
'DRIVER={ODBC Driver 13 for SQL Server}'
instead of
'DRIVER={SQL Server}'

I'm using Django 2.2
and got the same error while connecting to sql-server 2012. Spent lot of time to solve this issue and finally this worked.
I changed driver to
'driver': 'SQL Server Native Client 11.0'
and it worked.

Local Ms Sql database server need or {ODBC driver 17 for SQL Server} Azure Sql Database need{ODBC driver 13 for SQL SERVER}
Check installed drivers here => Installed ODBC Drivers
Format for connection to Azure Sql Database is :
import pyodbc
conn = pyodbc.connect['DRIVER={ODBC Driver 13 for SQL Server};'
'SERVER=tcp:nameServer.database.windows.net,1433;'
'DATABASE=Name database; UID=name; PWD=password;']
Format for connection to Ms SQL Databse Local is:
import pyodbc
conn = pyodbc.connect['DRIVER={ODBC Driver 17 for SQL Server};'
'SERVER=server.name;' // example Doctor-Notebook\\MSSQLEXPRESS
'DATABASE=database.name; Trusted_connection = yes']

I faced this issue and was looking for the solution. Finally I was trying all the options from the //github.com/mkleehammer/pyodbc/wiki/Connecting-to-SQL-Server-from-Windows , and for my MSSQL 12 only "{ODBC Driver 11 for SQL Server}" works. Just try it one by one. And the second important thing you have to get correct server name, because I thought preciously that I need to set \SQLEXPRESS in all of the cases, but found out that you have to set EXACTLY what you see in the server properties. Example on the screenshot:

You could try:
import pyodbc
# Using a DSN
cnxn = pyodbc.connect['DSN=odbc_datasource_name;UID=db_user_id;PWD=db_password']
Note: You will need to know the "odbc_datasource_name". In Windows you can search for ODBC Data Sources. The name will look something like this:

The below code works magic.
SQLALCHEMY_DATABASE_URI = "mssql+pyodbc:///?driver=SQL Server Native Client 11.0?trusted_connection=yes?UID" \
"=?PWD="

Below connection string is working

In my case, I was using wrong drivers to connect to Microsft SQL server
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']

I noticed that I was using "SQL server" as a driver for connecting to "Microsoft SQL server". I installed new ODBC driver and it worked well.
Don't use "MySQL ODBC Unicode/ANSI driver" to connect to Microsoft SQL servers. Instead install latest [or older as per requirement] from here
Also make sure that SQL server is allowed to accept remote connections.

Apart from the other answers, that considered the connection string itself, it might simply be necessary to download the correct odbc driver. My client just faced this issue when executing a python app, that required it. you can check this by pressing windows + typing "odbc". the correct driver should appear in the drivers tab.

Have you installed any product of SQL in your system machine ? You can download and install "ODBC Driver 13[or any version] for SQL Server" and try to run if you havent alerady done.

Create a DSN something like this [ASEDEV] for your connection and try to use DSN instead of DRIVER like below:
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']

I was facing the same issue whole day wasted and I tried all possible
conn_str = [
r'DRIVER = {SQL Server};'
r'SERVER=[local]\SQLEXPRESS;'
r'DATABASE=myDb;'
r'Trusted_Connection=yes;'
]
cnxn = pyodbc.connect[conn_str]
2 values
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']
3
In place of
conn_str = [
r'DRIVER = {SQL Server};'
r'SERVER=[local]\SQLEXPRESS;'
r'DATABASE=myDb;'
r'Trusted_Connection=yes;'
]
cnxn = pyodbc.connect[conn_str]
3 we can try these option one by one or just you can use with you corresponding setting, somehow in my case the last one works :]
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']

In my case, the exact same error was caused by the lack of the drivers on Windows Server 2019 Datacenter running in an Azure virtual machine.
As soon as I installed the drivers from //www.microsoft.com/en-us/download/details.aspx?id=56567, the issue was gone.

it worked for me; you need to install driver from here
//learn.microsoft.com/en-us/sql/connect/odbc/download-odbc-driver-for-sql-server?view=sql-server-ver15
or [in ubuntu]
conn_str = [
r'DRIVER = {SQL Server};'
r'SERVER=[local]\SQLEXPRESS;'
r'DATABASE=myDb;'
r'Trusted_Connection=yes;'
]
cnxn = pyodbc.connect[conn_str]
4 if you get an error with
conn_str = [
r'DRIVER = {SQL Server};'
r'SERVER=[local]\SQLEXPRESS;'
r'DATABASE=myDb;'
r'Trusted_Connection=yes;'
]
cnxn = pyodbc.connect[conn_str]

None of the above worked for me. What did work for me was the following:
Instead of passing a connection string like this:
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']
7
I passed the connection details as following:
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']

Hope this helps someone.

My issue; trying to connect using MFA and my email, which has the permissions for this database. I also made sure that I could connect to the database in the first place, just to be sure.
First of all, look at all the drivers:
connection = pyodbc.connect['Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
pyodbc.Error: ['IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [0] [SQLDriverConnect]']

Now you can set up your connection string; I had the list of available drivers. For Azure Authentication [now Microsoft Entra Id] this code worked for me:
conn_str = [
r'DRIVER = {SQL Server};'
r'SERVER=[local]\SQLEXPRESS;'
r'DATABASE=myDb;'
r'Trusted_Connection=yes;'
]
cnxn = pyodbc.connect[conn_str]
0
This opened a small window asking me to connect and add the Authentication code.
