      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('select * from score')
      print cur.fetchall()
      print "----------------------------------------"
      cur.execute("select count(*) from score")
      print "Current Rows is :",cur.fetchall()[0]
      cur.close()
