python-mysqlHow do I format a MySQL query in Python?
The Python Database API Specification v2.0 provides a common interface for various database systems. To access MySQL databases from Python, you need to install the MySQL Connector/Python package.
To format a MySQL query in Python, you need to use the following syntax:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword"
)
mycursor = mydb.cursor()
sql = "SELECT * FROM customers WHERE address = %s"
adr = ("Yellow Garden 2", )
mycursor.execute(sql, adr)
myresult = mycursor.fetchall()
for x in myresult:
print(x)
The output of the above code will be:
('John', 'Highway 21', 'Yellow Garden 2')
The code consists of the following parts:
import mysql.connector
: imports the MySQL Connector/Python package.mydb = mysql.connector.connect()
: creates a connection to the MySQL database.mycursor = mydb.cursor()
: creates a cursor to execute the query.sql = "SELECT * FROM customers WHERE address = %s"
: defines the SQL query.adr = ("Yellow Garden 2", )
: defines the parameters for the query.mycursor.execute(sql, adr)
: executes the query with the parameters.myresult = mycursor.fetchall()
: fetches the results of the query.for x in myresult:
: loops through the results.print(x)
: prints each result.
For more information, please refer to the MySQL Connector/Python documentation.
