Prerequisite: Python: MySQL Create Table

In this article, we are going to see how to get the size of a table in MySQL using Python. Python allows the integration of a wide range of database servers with applications. A database interface is required to access a database from Python. MySQL Connector-Python module is an API in python for communicating with a MySQL database

Approach:

• Set up a Database serving either locally or globally.
• Install Python Connector inorder to communicate with Databases.
• Establish Database Connection using a Connector.
• Need to have a Table to insert data, Create a Table if you don’t have any.
• Modify Data in Table [ CRUD operation ] using a cursor object returned by Connector.
• Close the Database connection If you are done with it.

We are going to use this table:

Example 1: Adding one row into a Table with static values :

Syntax : "INSERT INTO table_name (column_name) VALUES ( valuesOfRow );"

Below is the implementation:

import mysql.connector

db = mysql.connector.connect(
    host="localhost",
    user="root",
    passwd="root",
    database="testdb"
)
# getting the cursor by cursor() method
mycursor = db.cursor()

insertQuery = "INSERT INTO Fruits (Fruit_name) VALUES ('Apple');"

mycursor.execute(insertQuery)

print("No of Record Inserted :", mycursor.rowcount)

# we can use the id to refer to that row later.
print("Inserted Id :", mycursor.lastrowid)

# To ensure the Data Insertion, commit database.
db.commit() 

# close the Connection
db.close()

 Output:

No of Record Inserted : 1
Inserted Id : 1

Example 2: Adding multiple rows into a table with static values :

Syntax : ''INSERT INTO table_name (column_name) 

                             VALUES ( valuesOfRow1),(valuesOfRow2),....(valuesOfRowN);''

Below is the implementation:

import mysql.connector

db = mysql.connector.connect(
    host="localhost",
    user="root",
    passwd="root",
    database="testdb"
)

#getting the cursor by cursor() method
mycursor = db.cursor()

insertQuery = '''INSERT INTO 
            Fruits (Fruit_name, Taste, Production_in ) 
            VALUES ('Banana','Sweet',210);'''

mycursor.execute(insertQuery)

print("No of Record Inserted :", mycursor.rowcount)

# To ensure the data insertion, Always commit to the database.
db.commit()

# close the Connection
db.close()

Output:

No of Record Inserted : 2
