1.首先去www.sqlite.org下载一个sqlite,它是一个嵌入式数据库,没有服务器的概念,windows版的就是一个exe,自己把它放到一个合适的目录里,然后把这个目录加入系统的path变量.
2.然后去找个pysqlite,这是python访问sqlite的接口,地址在这里 : http://initd.org/tracker/pysqlite
目前针对不同的python版本,pysqlite有两个版本:2.3和2.4,请根据自己的python版本选用.
3.然后就可以打开自己喜欢的编辑器,写一段测试代码了.
4.中文处理要注意的是sqlite默认以utf-8编码存储.
5.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.
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')
