Data source name not found and no default driver specified in Azure Runbook

Question

I am trying to run this code in Azure Automation Runbook but always get the same error

cnxn = pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT='+port+';
DATABASE='+database+';UID='+username+';PWD='+password+';Authentication=ActiveDirectoryPassword')

Error:

pyodbc.InterfaceError: ('IM002', u'[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')

Answer 1

If you want to use pyodbc module to connect Azure sql database, the running environment should have Microsoft ODBC Driver for SQL Server. If it does not have the driver, you will get the error. For more details, please refer to the document . But Azure automation sandbox does not have the driver.

According to the situation, I suggest you host the script on Azure function.

For example(I host the script on Azure HTTP trigger function)

My code

async def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    
    server = 'jimtestsql.database.windows.net'
    database = 'test'
    username = 'jim@hanxia.onmicrosoft.com'
    password = 'Wdsr199545#'
    driver= '{ODBC Driver 17 for SQL Server}'
    cnxn = pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+ password+';Authentication=ActiveDirectoryPassword')
    cursor = cnxn.cursor()
    cursor.execute("SELECT Top(1) * FROM [dbo].[StarWars]")
    row = cursor.fetchone()

    return func.HttpResponse(str(row[0]) + " " + str(row[1]))
