Linux/Unix:

$ sudo easy_install ibm_db_sa-x.x.x-pyx.x.egg

3. To install IBM_DB_SA from source

Standard Python setup should be used::

python setup.py install

A TCP/IP connection can be specified as the following:

from sqlalchemy import create_engine

e = create_engine("db2+ibm_db://user:pass@host[:port]/database")

For a local socket connection, exclude the "host" and "port" portions:

from sqlalchemy import create_engine

e = create_engine("db2+ibm_db://user:pass@/database")

• IBM DB2 Universal Database for Linux/Unix/Windows versions 9.7 onwards
• IBM Db2 on Cloud

1. Non-standard SQL queries are not supported. e.g. "SELECT ? FROM TAB1"
2. For updations involving primary/foreign key references, the entries should be made in correct order. Integrity check is always on and thus the primary keys referenced by the foreign keys in the referencing tables should always exist in the parent table.
3. Unique key which contains nullable column not supported
4. UPDATE CASCADE for foreign keys not supported
5. DEFERRABLE INITIALLY deferred not supported
6. Subquery in ON clause of LEFT OUTER JOIN not supported
7. PyODBC and Jython/zxjdbc support is experimental

ibm_db_sa for SQLAlchemy was first produced by IBM Inc., targeting version 0.4. The library was ported for version 0.6 and 0.7 by Jaimy Azle. Port for version 0.8 and modernization of test suite by Mike Bayer.
