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 = "geeks"
  )
  
#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:

Python3




# Establish connection to MySQL database
import mysql.connector
  
db = mysql.connector.connect(
  host="localhost",
  user="root",
  password="root123",
  database = "geeks"
  )
  
#getting the cursor by cursor() method
mycursor = db.cursor()
  
insertQuery = " Select City, IF(City = 'Patna','True','False') from persons;"
mycursor.execute(insertQuery)
myresult = mycursor.fetchall()
  
print(myresult)
  
# close the Connection
db.close()

Output:
