We’re done with introductory part of sqlite and it’s helpful commands. tables pattern – list tables that match pattern header ON|OFF – Show or Hide Column headers mode mode table – Changes mode for a table read filename – Execute SQL Commands in Filename databases – Dump a table into an SQL text format When you work with sqlite there are some dot commands that you need to know to do some tasks effectively. But you need to know these commands to find out version of sqlite and it’s database library if you’re reporting errors to developer or building your own python packages. You don’t need to run them later as they’re not important. These are some introductory commands that you’re going to run for now. This command gives us sqlite database library version. This command will show you the pysqlite version of sqlite3. You can check it’s pysqlite binding version by typing the following command. ![]() SQLite3 is the latest version of sqlite as of now. You need to setup environment variables and add entry to python directory in PATH. If it’s throwing error then you’ve broken setup of python. ![]() This command will invoke python interpreter inside the command prompt irrespective of the directory. In order to test your installation of python under windows operating system. Now that we have all things that we need to run python, let’s start with the code. Windows users can follow this tutorial – python on windows.įor ironpython users, there is already one tutorial on this site, check Sqlite with Ironpyton. Ubuntu Linux users can read this tutorial for setting up python under ubuntu. If not then head over to and download the python distribution respective to your operating system version. I assume you have working python instillation on your operating system. Depending on your operating system, you need to have python setup on your computer. You just saw how to create a database in Python using the sqlite3 package.This tutorial is for those who want to learn how to use sqlite with python programming language. You’ll then get the following results: product_name price LEFT JOIN prices b ON a.product_id = b.product_idĭf = pd.DataFrame(c.fetchall(), columns=) You can then run the following code to display the results in Pandas DataFrame: import sqlite3 ![]() INSERT INTO products (product_id, product_name)įor the final step, let’s join the ‘ products‘ table with the ‘ prices‘ table using the product_id column which is present in both tables. Here is the complete code to insert the values into the 2 tables: import sqlite3 Let’s also insert the following data into the ‘ prices‘ table: product_id Step 2: Insert values into the tablesįor this step, let’s insert the following data into the ‘ products‘ table: product_id Once you run the above script in Python, a new file, called test_database, would be created at the same location where you saved your Python script. Here are the columns to be added for the 2 tables: Table Nameīelow is the script that you can use in order to create the database and the 2 tables using sqlite3: import sqlite3 nnect('database_name') Steps to Create a Database in Python using sqlite3 Step 1: Create the Database and Tables
