以下示例使用以下數(shù)據(jù)表結(jié)構(gòu)
CREATE TABLE users(
id int(11) NOT NULL AUTO_INCREMENT,
email varchar(255) COLLATE utf8_bin NOT NULL,
password varchar(255) COLLATE utf8_bin NOT NULL,
PRIMARY KEY (`id`)
)
ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin
AUTO_INCREMENT=1 ;
對這個表進行進行CRUD操作
import pymysql.cursors
# Connect to the database
connection = pymysql.connect(host='localhost',
user='user',
password='passwd',
db='db',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
try:
with connection.cursor() as cursor:
# Create a new record
sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
cursor.execute(sql, ('webmaster@python.org', 'very-secret'))
# connection is not autocommit by default. So you must commit to save
# your changes.
connection.commit()
with connection.cursor() as cursor:
# Read a single record
sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
cursor.execute(sql, ('webmaster@python.org',))
result = cursor.fetchone()
print(result)
finally:
connection.close()
這個例子將打印:
{'password': 'very-secret', 'id': 1}
