Mysql 左，右

我有一个带有day列的表，如下所示：

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

我可以得到明确的日期，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";

我只想要不同的月份和年份

select distinct(day) from Table where day between "2011-03-01" and "2011-04-28";

你能帮我吗

谢谢

DISTINCT可能只应用于mysql中的整行。所以，从约会开始，你首先需要知道你需要什么

select distinct(EXTRACT YEAR_MONTH FROM `day`) from Table 
      where day between "2011-03-01" and "2011-04-28";
