Examples

CRUD

The following examples make use of a simple table

  1. CREATE TABLE `users` (
  2.     `id` int(11) NOT NULL AUTO_INCREMENT,
  3.     `email` varchar(255) COLLATE utf8_bin NOT NULL,
  4.     `password` varchar(255) COLLATE utf8_bin NOT NULL,
  5.     PRIMARY KEY (`id`)
  6. ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin
  7. AUTO_INCREMENT=1 ;
  1. import pymysql.cursors
  3. # Connect to the database
  4. connection = pymysql.connect(host='localhost',
  5.                              user='user',
  6.                              password='passwd',
  7.                              db='db',
  8.                              charset='utf8mb4',
  9.                              cursorclass=pymysql.cursors.DictCursor)
  11. try:
  12.     with connection.cursor() as cursor:
  13.         # Create a new record
  14.         sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
  15.         cursor.execute(sql, ('webmaster@python.org', 'very-secret'))
  17.     # connection is not autocommit by default. So you must commit to save
  18.     # your changes.
  19.     connection.commit()
  21.     with connection.cursor() as cursor:
  22.         # Read a single record
  23.         sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
  24.         cursor.execute(sql, ('webmaster@python.org',))
  25.         result = cursor.fetchone()
  26.         print(result)
  27. finally:
  28.     connection.close()

This example will print:

  1. {'password': 'very-secret', 'id': 1}
