だから基本的にどのようにPythonでSQL DBに接続するには?私は今、同じことをやっている仮想ボットに取り組んでいます。モジュール、SQLコネクターを見てください!

host = localhost
database = python_mysql

読むconfig.iniの資格情報とのconfig.iniの作成を開始し、返す辞書
from configparser import ConfigParser
def read_db_config(filename='config.ini', section='mysql'):
""" Read database configuration file and return a dictionary object
:param filename: name of the configuration file
:param section: section of database configuration
:return: a dictionary of database parameters
"""
# create parser and read ini configuration file
parser = ConfigParser()
parser.read(filename)
# get section, default to mysql
db = {}
if parser.has_section(section):
items = parser.items(section)
for item in items:
db[item[0]] = item[1]
else:
raise Exception('{0} not found in the {1} file'.format(section, filename))
return db
をしてMySQLデータベースに接続します
from mysql.connector import MySQLConnection, Error
from python_mysql_dbconfig import read_db_config
def connect():
""" Connect to MySQL database """
db_config = read_db_config()
try:
print('Connecting to MySQL database...')
conn = MySQLConnection(**db_config)
if conn.is_connected():
print('connection established.')
else:
print('connection failed.')
except Error as error:
print(error)
finally:
conn.close()
print('Connection closed.')
if __name__ == '__main__':
connect()
と更新ステートメントは次のようになります
def update_book(book_id, title):
# read database configuration
db_config = read_db_config()
# prepare query and data
query = """ UPDATE books
SET title = %s
WHERE id = %s """
data = (title, book_id)
try:
conn = MySQLConnection(**db_config)
# update book title
cursor = conn.cursor()
cursor.execute(query, data)
# accept the changes
conn.commit()
except Error as error:
print(error)
finally:
cursor.close()
conn.close()
if __name__ == '__main__':
update_book(37, 'The Giant on the Hill *** TEST ***')
