SQLAlchemy: Get database name from engine

Question

After creating an SQLALchemy engine like this

engine = create_engine('mssql+pyodbc://user:pass@dbserver:port/db_name?driver=ODBC+Driver+13+for+SQL+Server)

Is there a way to get db_name from the engine-object? I know I can parse the name from the connection string but is there a better way of doing this? I had a look at the SQLAlchemy-API but couldn’t find an answer.

Answer 1

The engine provides the connection information, so you can access those parameters. For example, if you’re in the debugger, you can do:

(pdb) pp dir(dbconn.engine.url)
[...
 'database',
 'drivername',
 'get_backend_name',
 'get_dialect',
 'get_driver_name',
 'host',
 'password',
 'password_original',
 'port',
 'query',
 'translate_connect_args',
 'username']

So the simple way to get at the database name is:

engine.url.database
