How to Use IF Statement in MySQL Using Python
Prerequisite: Python: MySQL Create Table
In this article, we are going to see how to use if statements 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:
- Import module.
- Make a connection request with the database.
- Create an object for the database cursor.
- Execute the following MySQL query:
IF(condition, value_if_true, value_if_false)
Example 1:
In this example we are using this database table with the following query;
Below is the implementation:
Python3
# Establish connection to MySQL database import mysql.connector db = mysql.connector.connect( host="localhost", user="root", password="root123", database = "Beginner" ) #getting the cursor by cursor() method mycursor = db.cursor() insertQuery = " Select Value, IF(Value>1000,'MORE','LESS') from salary;"mycursor.execute(insertQuery) myresult = mycursor.fetchall() print(myresult) # close the Connection db.close() |
Output:
Example 2:
In this example we are using this database table with the following query;
Below is the full implementation:
