Note that many other databases are supported, the main criteria being the existence of a functional SQLAlchemy dialect and Python driver. Connection Timeout=30 means that the database server has 30 seconds to establish a connection.. conn_hive = pyodbc.connect('DSN = YOUR_DSN_NAME , SERVER = YOUR_SERVER_NAME, UID = USER_ID, PWD = PSWD' ) The best part of using pyodbc is that I have to import just one package to connect to almost any data source. Type hostname; Oracle. (dot) for localhost. Step 1: From start menu went to SQL server configuration manager. Connect import pyodbc # Some other example server values are # server = 'localhost\sqlexpress' # for a named instance # server = 'myserver,port' # to specify an alternate port server = 'tcp:myserver.database.windows.net' database = 'mydb' username = 'myusername' password = 'mypassword' # ENCRYPT defaults to yes starting in ODBC Driver 18. Although the linked article references SQL Server, these steps are also applicable to Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics. Make the group the Azure AD administrator of my Azure SQL Server; Again, if I connect to an Azure SQL database on my server I can run the script above successfully. cnxn = pyodbc.connect('driver={ODBC Driver 17 for SQL Server};Server=127.0.0.1, 1433;' Incidentally also did same using Ruby and FreeTDS, and Localhost,1433 worked all the time.. Must be something inside the pyodbc package or their approach that sometimes drop some info to make the DBMS on server fail to respond/timeout The second parameter contains our connection object. If you want to take a real test drive of Airflow, you should consider setting up a database backend to PostgreSQL, MySQL, or MSSQL.By default, Airflow uses SQLite, which is intended for development purposes only.. Airflow supports the following database engine versions, so make sure which version you have. A database driver is a computer program that implements a protocol (ODBC or JDBC) for a database connection. select @@ version; Code language: SQL (Structured Query Language) (sql) This query returns the version of the SQL Server.Third, click the Execute button:. Searching for the keyword "sqlalchemy + (database name)" should help get you to the right place. See the example at Custom DBAPI connect() arguments / on-connect routines.. creator .
