Watch Connect to PostgreSQL from Python (Using SQL in Python) | Python to PostgreSQL Video Tutorial

Connect to PostgreSQL from Python (Using SQL in Python) | Python to PostgreSQL In this video, we shall understand how to connect to PostgreSQL Database from Python. We shall write a python program which will use the Psycopg2 module to connect to the PostgreSQL database and then perform some database or SQL transactions such as creating a table and then insert data to the table, updating a table data and delete records from the table using python code. We shall also see how to fetch table data from postgres database to python program. If you’d like to practice SQL queries or explore my recorded SQL courses, check out my all-in-one SQL learning platform, SQLNest 👇 https://sqlnest.com/ At the end of the video, I will also cover how to use Context Manager to perform all of the above SQL operations. That is, we will use the WITH clause to connect to the database and also use the WITH clause to open the cursor. I will also mention what are the advantages of using WITH clause and why it is recommended to always use context manager or WITH clause when working with database in python. Download the Python script used in this video from my blog.

We shall start the video by covering the couple of pre-requisites which is to first install the psycopg2 module and then finding the credentials or information required to connect to the postgres database. After this we shall write the python program which will initially connect to the PostgreSQL database and then open a cursor which will be then used to perform the database operations like CREATE TABLE, INSERT INTO Table, UPDATE Table data, DELETE table record and also how to fetch or retrieve table records or table data from the database to Python program. Finally, we shall end the video by talking about context manager way of connecting to the database and also how to use context manager to open a cursor. Using context manager is simply using the WITH clause while connecting to the database and then also using the WITH clause while opening the cursor. I will also mention the advantages of using a context manager over the traditional method or connecting to data and opening the cursor. And also mention why is it recommended to always use context manager when connecting to database in python.
