""" The sqlite3 extension module provides a DB-API 2.0 (PEP 249) compliant interface to the SQLite library, and requires SQLite 3.7.15 or newer. To use the module, start by creating a database Connection object: import sqlite3 cx = sqlite3.connect("test.db") # test.db will be created or opened The special path name ":memory:" can be provided to connect to a transient in-memory database: cx = sqlite3.connect(":memory:") # connect to a database in RAM Once a connection has been established, create a Cursor object and call its execute() method to perform SQL queries: cu = cx.cursor() # create a table cu.execute("create table lang(name, first_appeared)") # insert values into a table cu.execute("insert into lang values (?, ?)", ("C", 1972)) # execute a query and iterate over the result for row in cu.execute("select * from lang"): print(row) cx.close() The sqlite3 module is written by Gerhard Häring <gh@ghaering.de>.
