这篇文章主要介绍了Python简单操作sqlite3的方法,结合实例形式分析了Python针对sqlite3数据库的读取、创建、增删改查等基本操作技巧,需要的朋友可以参考下

import sqlite3
def Test1():
  #con =sqlite3.connect("D:\\test.db")
  con =sqlite3.connect(":memory:") #store in memory
  cur =con.cursor()
  try:
    cur.execute('create table score(id integer primary key,name varchar(10),scores integer)')
    cur.execute("insert into score values(0,'Rose',87)")
    cur.execute("insert into score values(1,'Alice',78)")
    cur.execute("insert into score values(2,'Helon',100)")
    cur.execute("insert into score values(3,'Tom',98)")
    cur.execute("insert into score values(4,'jack',198)")
    cur.execute("insert into score values(5,'Tony',198)")
    cur.execute("insert into score values(6,'David',99)")
    cur.execute("update score set scores =? where id=?",(45,3))
    cur.execute("update score set name=? where id=?",("John",0))
    cur.execute("delete from score where id =1")
  except Exception,e:
    print "There are some except",e
  con.commit()
  print "Insert Complete"
  print "-----------------------------------------"
  print "Last row id is ",cur.lastrowid
  cur.execute('select * from score')
  print cur.fetchall()
  print "----------------------------------------"
  cur.execute("select count(*) from score")
  print "Current Rows is :",cur.fetchall()[0]
  cur.close()
  con.close()
if name =='main':
  Test1()
  print "hello world"
