python2.5以上版本已经集成了sqlite模块,下面是一些基本用法

python">#!/usr/bin/python
# -*- coding: iso-8859-1 -*-
from sqlite3 import dbapi2 as sqlite

# Create a database:
con = sqlite.connect('mydatabase.db3')
cur = con.cursor()

# Create a table:
cur.execute('create table clients (id INT PRIMARY KEY, name CHAR(60))')

# Insert a single line:
client = (5,"John Smith")
cur.execute("insert into clients (id, name) values (?, ?)", client )
con.commit()

# Insert several lines at once:
clients = [ (7,"Ella Fitzgerald"),
            (8,"Louis Armstrong"),
            (9,"Miles Davis")
          ]
cur.executemany("insert into clients (id, name) values (?, ?)", clients )
con.commit()

cur.close()
con.close()

#下面的代码对数据库进行连接查询
#!/usr/bin/python
# -*- coding: iso-8859-1 -*-
from sqlite3 import dbapi2 as sqlite

# Connect to an existing database
con = sqlite.connect('mydatabase.db3')
cur = con.cursor()

# Get row by row
print "Row by row:"
cur.execute('select id, name from clients order by name;')
row = cur.fetchone()
while row:
    print row
    row = cur.fetchone()

# Get all rows at once:
print "All rows at once:"
cur.execute('select id, name from clients order by name;')
print cur.fetchall()

cur.close()
con.close()
