如何用矩阵填充数据表的指定范围

import mysql.connector

# 连接到MySQL数据库
cnx = mysql.connector.connect(user='your_username', password='your_password',
                              host='your_host', database='your_database')

# 创建游标对象
cursor = cnx.cursor()

# 创建数据表
create_table_query = '''
CREATE TABLE IF NOT EXISTS data_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    value INT
)
'''
cursor.execute(create_table_query)

# 生成矩阵数据
matrix_data = [[1, 2, 3],
               [4, 5, 6],
               [7, 8, 9]]

# 插入数据
insert_query = 'INSERT INTO data_table (value) VALUES (%s)'
for row in matrix_data:
    for value in row:
        cursor.execute(insert_query, (value,))
    cnx.commit()

# 验证数据
select_query = 'SELECT * FROM data_table'
cursor.execute(select_query)
result = cursor.fetchall()
for row in result:
    print(row)

# 关闭游标和数据库连接
cursor.close()
cnx.close()
