Project description
Usage Sample ''''''''''''
.. code:: python
import executor
if name == 'main': executor.init_db('test.db', driver='sqlite3', debug=True)
# or
executor.init_db("postgres://user:password@127.0.0.1:5432/testdb", driver='psycopg2', pool_size=5, debug=True)
# or
executor.init_db(host='127.0.0.1', port='5432', user='xxx', password='xxx', database='testdb', driver='psycopg2')
# if driver is 'pymysql' or 'mysql.connector' of MySQL, the select_key is 'SELECT LAST_INSERT_ID()'
select_key = "SELECT currval('person_id_seq')"
id = executor.save(select_key, 'INSERT INTO person(name, age) VALUES(%s,%s)', 'wangwu', 38)
persons = executor.select('select id, name, age from person')
# result:
# (3, 'zhangsan', 15)
# (4, 'lisi', 26)
# (5, 'wangwu', 38)
# (6, 'zhaoliu', 45)
persons = executor.select_one('select id, name, age from person where name = %s', 'zhangsan')
# result:
# (3, 'zhangsan', 15)
args = [
('李四', 55),
('王五', 35),
]
executor.batch_execute('INSERT INTO person(name,age) VALUES(%s,%s)', *args)
executor.close()
Transaction ''''''''''''

@with_transaction def test_transaction(): insert_func(....) update_func(....)
def test_transaction2(): with transaction(): insert_func(....) update_func(....)
