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()
|
|
