用python访问sqlite

                准备工作:Python , SQLite , PySQLite
开始:
import pysqlite2.dbapi2 as sqlite

   

def runTest():

    cx = sqlite.connect('test.db')

    cu = cx.cursor()

   

    #create

    cu.execute('''create table catalog(

        id integer primary key,

        pid integer,

        name varchar(10) unique

        )''')


    #insert

    cu.execute('insert into catalog values(0,0,"张小山")')

    cu.execute('insert into catalog values(1,0,"hello")')

    cx.commit()

   

    #select

    cu.execute('select * from catalog')

    print '1:',

    print cu.rowcount

    rs = cu.fetchmany(1)

    print '2:',

    print rs

    rs = cu.fetchall()

    print '3:',

    print rs

   

    #delete

    cu.execute('delete from catalog where id = 1 ')

    cx.commit()

   

   

    cu.execute('select * from catalog')

    rs = cu.fetchall()

    print '4:',

    print rs

   

    #select count

    cu.execute("select count(*) from catalog")

    rs = cu.fetchone()

    print '5:',

    print rs

   

   

    cu.execute("select * from catalog")

    cu.execute('drop table catalog')


if __name__ == '__main__':

    runTest()
1.中文处理要注意的是sqlite默认以utf-8编码存储.
2.另外要注意sqlite仅支持文件锁,换句话说,它对并发的处理并不好,不推荐在网络环境使用,适合单机环境.
