python-mysqlHow do I use a Python MySQL refresh cursor?


Using a cursor to refresh a MySQL table in Python is a relatively simple process.

First, you need to establish a connection to the database and create a cursor object. This can be done using the mysql.connector library.

import mysql.connector

# Establish connection to the database
mydb = mysql.connector.connect(
    host="localhost",
    user="yourusername",
    passwd="yourpassword",
    database="yourdatabase"
)

# Create a cursor object
mycursor = mydb.cursor()

Once the connection is established and the cursor is created, you can execute the refresh command. This command will reload the table's content from the data file on disk.

mycursor.execute("REFRESH TABLE yourtable")

The refresh command can also be used with additional parameters. For example, you can specify the FORCE flag to force the refresh even if the table is in use by another connection.

mycursor.execute("REFRESH TABLE yourtable FORCE")

Finally, you should commit the changes to the database.

mydb.commit()

For more information on the refresh command, see the MySQL Documentation.
