This dialect allows you to use the SAP HANA database with SQLAlchemy. It can use the supported SAP HANA Python Driver hdbcli (supported since SAP HANA SPS 2) or the open-source pure Python client PyHDB. Please notice that sqlalchemy-hana isn't an official SAP product and isn't covered by SAP support.

Python 2.7 or Python 3.X with installed SAP HANA DBAPI implementation.

SAP HANA Python Driver see SAP HANA Client Interface Programming Reference or the install section of PyHDB.

Install from Python Package Index:

$ pip install sqlalchemy-hana

You can also install the latest version direct from a cloned git repository.

$ git clone https://github.com/SAP/sqlalchemy-hana.git
$ cd sqlalchemy-hana
$ python setup.py install

If you do not have access to a SAP HANA server, you can also use the SAP HANA Express edition.

After installation of sqlalchemy-hana, you can create a engine which connects to a SAP HANA instance. This engine works like all other engines of SQLAlchemy.

from sqlalchemy import create_engine
engine = create_engine('hana://username:[email protected]:30015')

By default the hana:// schema will use hdbcli (from the SAP HANA Client) as underlying database driver. To use PyHDB as driver use hana+pyhdb:// as schema in your DBURI.

In case of a tenant database, you may use:

from sqlalchemy import create_engine
engine = engine = create_engine('hana://user:pass@host/tenant_db_name')
