[英]MySQL distinct and left, right
I have a table with day column like this:我有一个这样的天列表:
2011-04-28, 2011-04-29 ...
day count name surname
2011-04-28 8 titi tutu
2011-04-28 12 tutu toto
2011-04-27 2 tutu toto
2011-03-12 10 tutu toto
I can obtain distinct day but not only month and year.我可以获得不同的日期,但不仅仅是月份和年份。
select distinct(day) from Table where day between "2011-03-01" and "2011-04-28";
I want only distinct month and year.我只想要不同的月份和年份。
Can you help me?你能帮助我吗?
Thanks谢谢
select DISTINCT EXTRACT(YEAR_MONTH FROM `day`) as yearmonth
from Table
where day between '2011-03-01' and '2011-04-28';
