python-简单的sqlite3使用

 # 导入SQLite驱动:
 >>> import sqlite3
 # 连接到SQLite数据库
 # 数据库文件是test.db
 # 如果文件不存在，会自动在当前目录创建:
 >>> conn = sqlite3.connect('test.db')
 # 创建一个Cursor:
 >>> cursor = conn.cursor()
 # 执行一条SQL语句，创建user表:
 >>> cursor.execute('create table user (id varchar(20) primary key, name varchar(20))')
 <sqlite3.Cursor object at 0x10f8aa260>
 # 继续执行一条SQL语句，插入一条记录:
 >>> cursor.execute('insert into user (id, name) values (\'1\', \'Michael\')')
 <sqlite3.Cursor object at 0x10f8aa260>
 # 通过rowcount获得插入的行数:
 >>> cursor.rowcount
 1
 # 关闭Cursor:
 >>> cursor.close()
 # 提交事务:
 >>> conn.commit()
 # 关闭Connection:
 >>> conn.close()

 >>> conn = sqlite3.connect('test.db')
 >>> cursor = conn.cursor()
 # 执行查询语句:
 >>> cursor.execute('select * from user where id=?', ('',))
 <sqlite3.Cursor object at 0x10f8aa340>
 # 获得查询结果集:
 >>> values = cursor.fetchall()
 >>> values
 [('', 'Michael')]
 >>> cursor.close()
 >>> conn.close()
