devart-postgresql-connector 1.2.0

New level of functionality and performance in data access via Python

Python Connector for PostgreSQL

Python Connector for PostgreSQL is a connectivity solution for accessing PostgreSQL databases from Python applications. It fully implements the Python DB API 2.0 specification. The connector is distributed as a wheel package for Windows, macOS, and Linux.

Direct connection

The connector enables you to establish a direct connection to PostgreSQL from a Python application via TCP/IP, eliminating the need for the database client library. A direct connection increases the speed of data transmission between the application and PostgreSQL database server. It also streamlines the deployment process since you don't have to distribute any client libraries with the application.

Secure communication

The connector supports encrypted communications using SSL/TLS, SSH tunneling, and HTTP/HTTPS tunneling.

Using the connector

To retrieve data from a database:

Import the module.

import devart.postgresql

Connect to a database using the connect() module method and obtain a connection object.

my_connection = devart.postgresql.connect(
    Server="your_server",
    Database="your_database",
    UserId="your_username",
    Password="your_password"
)

Create a cursor object using the cursor() connection method.

my_cursor = my_connection.cursor()

Execute the SQL statement using the execute() cursor method.

my_cursor.execute("SELECT * FROM employees")

Retrieve the result set using one of the fetch*() cursor methods.

for row in my_cursor.fetchall(): 
    print(row)
