MySQL server is an open-source relational database management system which is a major support for web-based applications. Databases and related tables are the main component of many websites and applications as the data is stored and exchanged over the web. In order to access MySQL databases from a web server(here XAMPP) we use various modules in Python such as PyMySQL, mysql.connector, etc.

In this article, we will see how to get the all rows of a MySQL table by making a database connection between python and MySQL.

First, we are going to connect to a database having a MySQL table. The SQL query to be used to get all the rows:

SELECT * FROM table-name

Finally, after getting all the rows, display each row in the table using an iterator.

Below are some programs which depict how to extract rows from a MySQL table in a Database:

Example 1:

Below is the table geeksdemo is database geek which is going to be accessed by a Python script:

Below is the program to get all the rows in an MYSQL table:

Python3

import pymysql

pymysql.install_as_MySQLdb()

import MySQLdb

db= MySQLdb.connect("localhost", "root", "", "GEEK")

cursor= db.cursor()

cursor.execute("SELECT * FROM geeksdemo")

result = cursor.fetchall()

for row in result:

print(row)

print("\n")

Output:

Example 2:

Here is another example to extracts all the rows from a table in a given database, below is the table scheme and rows:

Below is the Python script extract all each row from the table:

Python3

import MySQLdb

import pymysql

pymysql.install_as_MySQLdb()

db = MySQLdb.connect("localhost", "root", "", "techgeeks")

cursor = db.cursor()

cursor.execute("SELECT * FROM techcompanies")

result = cursor.fetchall()

for row in result:

print(row, '\n')

Output:

Here, we are going to learn how to create a program in Python to print the content of an SQL table?
Submitted by Shivang Yadav, on February 14, 2021

Python programming language is a high-level and object-oriented programming language developed by Guido Van Rossum, when he was working at CWI (Centrum Wiskunde & Informatica) which is a National Research Institute for Mathematics and Computer Science in the Netherlands.

In this era of machine learning and AI, the language has become so versatile that it can be used for performing multiple tasks. And backend development is one of them.

Using Python, we can access and manipulate databases and perform other backend tasks. Python has a library named 'pymysql' to perform the mySQL task and execute the queries.

We need to access the database using Python and then get the content of the table we have created in here, create an SQL table.

And then we will print the content of this table on screen.

Steps to display content of table in python:

Step 1: Connect to database using connect() method.
Step 2: Create a command to execute the query using cursor() method.
Step 3: And then we have used the fetchAll() method which is stored in rows.
Step 4: Print all elements of rows.

Program to display contents of table in Python

import  pymysql as ps

try:
    cn=ps.connect(host='localhost',port=3306,user='root',password='123',db='tata')
    
    cmd=cn.cursor()
    
    query="select * from products"
    
    cmd.execute(query)
    
    rows=cmd.fetchall()
    
    # print(rows)
    for row in rows:
        for col in row:
            print(col,end=' ')
        print()
    
    cn.close()

except Exception as e:
    print(e)

Output:

002 iPad Pro 75000 2020
