[agapple]

测试的表：

CREATE TABLE `test_bit_all` (
  id int(10) unsigned NOT NULL AUTO_INCREMENT,
  bit1 bit(1),
  bit2 bit(9),
  bit3 bit(17),
  bit4 bit(25),
  bit5 bit(33),
  bit6 bit(41),
  bit7 bit(49),
  bit8 bit(57),
  bit9 bit(64),
  PRIMARY KEY (`id`)
  )  ENGINE=InnoDB DEFAULT CHARSET=gbk;

构造数据：
insert into test_bit_all(id,bit1,bit2,bit3,bit4,bit5,bit6,bit7,bit8,bit9) values(null,18446744073709551615,18446744073709551615,18446744073709551615,18446744073709551615,18446744073709551615,18446744073709551615,18446744073709551615,18446744073709551615,18446744073709551615) ;
