Database Error

What This Error Means

This error occurs when you try to use the 'execute_many' method on a cursor object that does not support it. This is typically because the database connection is not configured to support batch operations.

Why It Happens

This error can happen when you're using a SQLite database connection, which does not support 'execute_many' method. Also, this error can occur if your database connection is set to use a MySQL database, but the 'execute_many' method is not enabled in the connection.

How to Fix It

1. 1To fix this error, you can use a loop to execute the query for each item in the list, or use the 'executemany' method from the 'sqlite3' module if you're using SQLite. Alternatively, you can enable the 'execute_many' method in your MySQL connection by setting 'multi_statements' to True in your connection string.

Example Code Solution

import sqlite3
conn = sqlite3.connect(':memory:')
cursor = conn.cursor()
insert_data = [(1, 'John'), (2, 'Jane')]
cursor.execute_many('INSERT INTO users (id, name) VALUES (?, ?)', insert_data)

import sqlite3
conn = sqlite3.connect(':memory:')
cursor = conn.cursor()
insert_data = [(1, 'John'), (2, 'Jane')]
cursor.executemany('INSERT INTO users (id, name) VALUES (?, ?)', insert_data)
