);import pycovenantsql
# Connect to the database with dsn
# host and port are your local CovenantSQL Adapter server
connection = pycovenantsql.connect(
dsn='covenantsql://your_database_id',
host='localhost',
port=11108,
)
try:
with connection.cursor() as cursor:
# Create a new record
sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
cursor.execute(sql, ('[email protected]', 'very-secret'))
# connection is autocommit. No need to commit in any case.
# connection.commit()
with connection.cursor() as cursor:
# Read a single record
sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
cursor.execute(sql, ('[email protected]',))
result = cursor.fetchone()
