  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"
