MySQL 获得当前日期时间函数

获得当前日期+时间（date + time）函数：now()

mysql> select now();

+---------------------+
| now() |
+---------------------+
| 2008-08-08 22:20:46 |
+---------------------+

获得当前日期+时间（date + time）函数：sysdate()

sysdate() 日期时间函数跟 now() 类似，不同之处在于：now() 在执行开始时值就得到了， sysdate() 在函数执行时动态得到值。看下面的例子就明白了：

mysql> select now(), sleep(3), now();

+---------------------+----------+---------------------+
| now() | sleep(3) | now() |
+---------------------+----------+---------------------+
| 2008-08-08 22:28:21 | 0 | 2008-08-08 22:28:21 |
+---------------------+----------+---------------------+

sysdate() 日期时间函数，一般情况下很少用到。

MySQL 获得当前时间戳函数：current_timestamp, current_timestamp()

mysql> select current_timestamp, current_timestamp();

+---------------------+---------------------+
| current_timestamp | current_timestamp() |
+---------------------+---------------------+
| 2008-08-09 23:22:24 | 2008-08-09 23:22:24 |
+---------------------+---------------------+

MySQL 日期转换函数、时间转换函数

MySQL Date/Time to Str（日期/时间转换为字符串）函数：date_format(date,format), time_format(time,format)

mysql> select date_format('2008-08-08 22:23:01', '%Y%m%d%H%i%s');

+----------------------------------------------------+
| date_format('2008-08-08 22:23:01', '%Y%m%d%H%i%s') |
+----------------------------------------------------+
| 20080808222301 |
+----------------------------------------------------+

MySQL 日期、时间转换函数：date_format(date,format), time_format(time,format) 能够把一个日期/时间转换成各种各样的字符串格式。它是 str_to_date(str,format) 函数的一个逆转换。

MySQL Str to Date （字符串转换为日期）函数：str_to_date(str, format)

select str_to_date('08/09/2008', '%m/%d/%Y'); -- 2008-08-09
select str_to_date('08/09/08' , '%m/%d/%y'); -- 2008-08-09
select str_to_date('08.09.2008', '%m.%d.%Y'); -- 2008-08-09
select str_to_date('08:09:30', '%h:%i:%s'); -- 08:09:30
select str_to_date('08.09.2008 08:09:30', '%m.%d.%Y %h:%i:%s'); -- 2008-08-09 08:09:30

可以看到，str_to_date(str,format) 转换函数，可以把一些杂乱无章的字符串转换为日期格式。另外，它也可以转换为时间。“format” 可以参看 MySQL 手册。

MySQL （日期、天数）转换函数：to_days(date), from_days(days)

select to_days('0000-00-00'); -- 0
select to_days('2008-08-08'); -- 733627

MySQL （时间、秒）转换函数：time_to_sec(time), sec_to_time(seconds)

select time_to_sec('01:00:05'); -- 3605
select sec_to_time(3605); -- '01:00:05'

MySQL 拼凑日期、时间函数：makdedate(year,dayofyear), maketime(hour,minute,second)

select makedate(2001,31); -- '2001-01-31'
select makedate(2001,32); -- '2001-02-01'
select maketime(12,15,30); -- '12:15:30'

MySQL （Unix 时间戳、日期）转换函数

unix_timestamp(),
unix_timestamp(date),
from_unixtime(unix_timestamp),
from_unixtime(unix_timestamp,format)

下面是示例：

select unix_timestamp(); -- 1218290027
select unix_timestamp('2008-08-08'); -- 1218124800
select unix_timestamp('2008-08-08 12:30:00'); -- 1218169800

select from_unixtime(1218290027); -- '2008-08-09 21:53:47'
select from_unixtime(1218124800); -- '2008-08-08 00:00:00'
select from_unixtime(1218169800); -- '2008-08-08 12:30:00'

select from_unixtime(1218169800, '%Y %D %M %h:%i:%s %x'); -- '2008 8th August 12:30:00 2008'

MySQL 日期时间计算函数

MySQL 为日期增加一个时间间隔：date_add()

set @dt = now();

select date_add(@dt, interval 1 day); -- add 1 day
select date_add(@dt, interval 1 hour); -- add 1 hour
select date_add(@dt, interval 1 minute); -- ...
select date_add(@dt, interval 1 second);
select date_add(@dt, interval 1 microsecond);
select date_add(@dt, interval 1 week);
select date_add(@dt, interval 1 month);
select date_add(@dt, interval 1 quarter);
select date_add(@dt, interval 1 year);

select date_add(@dt, interval -1 day); -- sub 1 day

MySQL adddate(), addtime()函数，可以用 date_add() 来替代。下面是 date_add() 实现 addtime() 功能示例：

mysql> set @dt = '2008-08-09 12:12:33';

mysql>
mysql> select date_add(@dt, interval '01:15:30' hour_second);

+------------------------------------------------+
| date_add(@dt, interval '01:15:30' hour_second) |
+------------------------------------------------+
| 2008-08-09 13:28:03 |
+------------------------------------------------+

mysql> select date_add(@dt, interval '1 01:15:30' day_second);

+-------------------------------------------------+
| date_add(@dt, interval '1 01:15:30' day_second) |
+-------------------------------------------------+
| 2008-08-10 13:28:03 |
+-------------------------------------------------+

MySQL 为日期减去一个时间间隔：date_sub()

mysql> select date_sub('1998-01-01 00:00:00', interval '1 1:1:1' day_second);

+----------------------------------------------------------------+
| date_sub('1998-01-01 00:00:00', interval '1 1:1:1' day_second) |
+----------------------------------------------------------------+
| 1997-12-30 22:58:59 |
+----------------------------------------------------------------+

MySQL date_sub() 日期时间函数和 date_add() 用法一致，不再赘述。

MySQL 日期、时间相减函数：datediff(date1,date2), timediff(time1,time2)

MySQL datediff(date1,date2)：两个日期相减 date1 - date2，返回天数。
select datediff('2008-08-08', '2008-08-01'); -- 7
select datediff('2008-08-01', '2008-08-08'); -- -7

MySQL timediff(time1,time2)：两个日期相减 time1 - time2，返回 time 差值。

select timediff('2008-08-08 08:08:08', '2008-08-08 00:00:00'); -- 08:08:08
select timediff('08:08:08', '00:00:00'); -- 08:08:08

注意：timediff(time1,time2) 函数的两个参数类型必须相同。

MySQL 时间戳（timestamp）转换、增、减函数：

timestamp(date) -- date to timestamp
timestamp(dt,time) -- dt + time
timestampadd(unit,interval,datetime_expr) --
timestampdiff(unit,datetime_expr1,datetime_expr2) --

请看示例部分：

select timestamp('2008-08-08'); -- 2008-08-08 00:00:00
select timestamp('2008-08-08 08:00:00', '01:01:01'); -- 2008-08-08 09:01:01
select timestamp('2008-08-08 08:00:00', '10 01:01:01'); -- 2008-08-18 09:01:01

select timestampadd(day, 1, '2008-08-08 08:00:00'); -- 2008-08-09 08:00:00
select date_add('2008-08-08 08:00:00', interval 1 day); -- 2008-08-09 08:00:00

MySQL timestampadd() 函数类似于 date_add()。
select timestampdiff(year,'2002-05-01','2001-01-01'); -- -1
select timestampdiff(day ,'2002-05-01','2001-01-01'); -- -485
select timestampdiff(hour,'2008-08-08 12:00:00','2008-08-08 00:00:00'); -- -12

select datediff('2008-08-08 12:00:00', '2008-08-01 00:00:00'); -- 7

MySQL timestampdiff() 函数就比 datediff() 功能强多了，datediff() 只能计算两个日期（date）之间相差的天数。

MySQL 时区（timezone）转换函数

convert_tz(dt,from_tz,to_tz)

select convert_tz('2008-08-08 12:00:00', '+08:00', '+00:00'); -- 2008-08-08 04:00:00

时区转换也可以通过 date_add, date_sub, timestampadd 来实现。

select date_add('2008-08-08 12:00:00', interval -8 hour); -- 2008-08-08 04:00:00
select date_sub('2008-08-08 12:00:00', interval 8 hour); -- 2008-08-08 04:00:00
select timestampadd(hour, -8, '2008-08-08 12:00:00'); -- 2008-08-08 04:00:00

select curdate(); -- 获取当前日期

select DATE_ADD(curdate(),interval -day(curdate())+1 day) -- 获取本月第一天

select last_day(curdate()); -- 获取当月最后一天

select date_add(curdate()-day(curdate())+1,interval 1 month ) -- 获取下个月的第一天

select DATEDIFF(date_add(curdate()-day(curdate())+1,interval 1 month ),DATE_ADD(curdate(),interval -day(curdate())+1 day)) from dual -- 获取当前月的天数

MySQL统计函数记录——按月、按季度、按日、时间段统计

按年汇总，统计：

select sum(mymoney) as totalmoney, count(*) as sheets from mytable group by date_format(col, '%Y');

按月汇总，统计：

select sum(mymoney) as totalmoney, count(*) as sheets from mytable group by date_format(col, '%Y-%m');

按季度汇总，统计：

select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by concat(date_format(col, '%Y'),FLOOR((date_format(col, '%m')+2)/3));

按小时：

select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by date_format(col, '%Y-%m-%d %H ');

查询本年度的数据:

SELECT * FROM mytable WHERE year(FROM_UNIXTIME(my_time)) = year(curdate())

查询数据附带季度数:

SELECT id, quarter(FROM_UNIXTIME(my_time)) FROM mytable;

查询本季度的数据:

SELECT * FROM mytable WHERE quarter(FROM_UNIXTIME(my_time)) = quarter(curdate());

本月统计:

select * from mytable where month(my_time1) = month(curdate()) and year(my_time2) = year(curdate())

本周统计:

select * from mytable where month(my_time1) = month(curdate()) and week(my_time2) = week(curdate())

N天内记录:

WHERE TO_DAYS(NOW())-TO_DAYS(时间字段)<=N
