PostgreSQL driver and tools library.
Project description
py-postgresql is a set of Python modules providing interfaces to various parts of PostgreSQL. Primarily, it provides a pure-Python driver with some C optimizations for querying a PostgreSQL database.
http://github.com/python-postgres/fe
Features:
Prepared Statement driven interfaces.
Cluster tools for creating and controlling a cluster.
Support for most PostgreSQL types: composites, arrays, numeric, lots more.
COPY support.
Sample PG-API Code:
>>> import postgresql
>>> db = postgresql.open('pq://user:password@host:port/database')
>>> db.execute("CREATE TABLE emp (emp_first_name text, emp_last_name text, emp_salary numeric)")
>>> make_emp = db.prepare("INSERT INTO emp VALUES ($1, $2, $3)")
>>> make_emp("John", "Doe", "75,322")
>>> with db.xact():
... make_emp("Jane", "Doe", "75,322")
... make_emp("Edward", "Johnson", "82,744")
...
There is a DB-API 2.0 module as well:
postgresql.driver.dbapi20
However, PG-API is recommended as it provides greater utility.
Once installed, try out the pg_python console script:
$ python3 -m postgresql.bin.pg_python -h localhost -p port -U theuser -d database_name
If a successful connection is made to the remote host, it will provide a Python console with the database connection bound to the db name.
