python sqlite3使用

python sqlite3文档地址:http://docs.python.org/2/library/sqlite3.html

The sqlite3 module was written by Gerhard Häring. It provides a SQL interface compliant with the DB-API 2.0 specification described by PEP 249.

To use the module, you must first create a Connection object that represents the database. Here the data will be stored in the example.db file:

import sqlite3

conn = sqlite3.connect('example.db')

You can also supply the special name :memory: to create a database in RAM.

Once you have a Connection, you can create a Cursor object and call its execute() method to perform SQL commands:

c = conn.cursor()

# Create table

c.execute('''CREATE TABLE stocks

             (date text, trans text, symbol text, qty real, price real)''')

# Insert a row of data

c.execute("INSERT INTO stocks VALUES ('2006-01-05','BUY','RHAT',100,35.14)")

# Save (commit) the changes

conn.commit()

# We can also close the connection if we are done with it.

# Just be sure any changes have been committed or they will be lost.

conn.close()
