关于MySQL的insert添加自动获取日期的now()的用法

例如我的MySQL数据库里有个表table1，它的字段有id，date1，date2，除id外都是Datetime类型的。
那么插值语句这样写：
insert into table1(date1,date2) values(now(),now());

有以下代码过程

INSERT INTO 表名
  (YEAR,
   USERRANGE,
   DIFFICULTY,
   QUESTIONTYPE,
   QUESTIONFORM,
   ABOUTNH,
   ABOUTDY,
   AREA,
   DESCRIPTION,
   LASTTIME,
   ZUJUANTIMES,
   INSERTUSER,
   INSERDATE,
   UPDATEUSER,
   UPDATEDATE,
   ISDELETE,
   KNOWLEDGENUM)
VALUES
  (22,
   33,
   #{DIFFICULTY},
   #{QUESTIONTYPE},
   #{QUESTIONFORM},
   #{ABOUTNH},
   #{ABOUTDY},
   #{AREA},
   #{DESCRIPTION},
   #{LASTTIME},
   #{ZUJUANTIMES},
   #{INSERTUSER},
   #{INSERDATE},
   #{UPDATEUSER},
   #{UPDATEDATE},
   #{ISDELETE},
   #{KNOWLEDGENUM})

INSERT INTO QUESTION
  (YEAR,
   USERRANGE,
   DIFFICULTY,
   QUESTIONTYPE,
   QUESTIONFORM,
   ABOUTNH,
   ABOUTDY,
   AREA,
   DESCRIPTION,
   LASTTIME(NOW(), '%Y-%m-%d'),
   ZUJUANTIMES,
   INSERTUSER,
   INSERDATE(NOW(), '%Y-%m-%d'),
   UPDATEUSER,
   UPDATEDATE(NOW(), '%Y-%m-%d'),
   ISDELETE,
   KNOWLEDGENUM)
VALUES
  (#{YEAR},
   #{USERRANGE},
   #{DIFFICULTY},
   #{QUESTIONTYPE},
   #{QUESTIONFORM},
   #{ABOUTNH},
   #{ABOUTDY},
   #{AREA},
   #{DESCRIPTION},
   #{INSERTUSER = -1},
   #{UPDATEUSER = -1},
   #{ISDELETE = 'F' },
   #{KNOWLEDGENUM = 203})

INSERT INTO QUESTION
  (YEAR,
   USERRANGE,
   DIFFICULTY,
   QUESTIONTYPE,
   QUESTIONFORM,
   ABOUTNH,
   ABOUTDY,
   AREA,
   DESCRIPTION,
   LASTTIME,
   ZUJUANTIMES,
   INSERTUSER,
   INSERDATE,
   UPDATEUSER,
   UPDATEDATE,
   ISDELETE,
   KNOWLEDGENUM)
VALUES
  (#{YEAR},
   #{USERRANGE},
   #{DIFFICULTY},
   #{QUESTIONTYPE},
   #{QUESTIONFORM},
   #{ABOUTNH},
   #{ABOUTDY},
   #{AREA},
   #{DESCRIPTION},
   #{NOW() },
   #{INSERTUSER = -1},
   #{NOW() },
   #{UPDATEUSER = -1},
   #{NOW() },
   #{ISDELETE = 'F' },
   #{KNOWLEDGENUM = 203})

(NOW(),'%Y-%m-%d')这个用法只显示年月日
