DATE_FORMAT

select DATE_FORMAT(create_time,'%Y%u') weeks,count(caseid) count from tc_case group by weeks; select DATE_FORMAT(create_time,'%Y%m%d') days,count(caseid) count from tc_case group by days; select DATE_FORMAT(create_time,'%Y%m') months,count(caseid) count from tc_case group by months;

DATE_FORMAT(date,format)
根据format字符串格式化date值。下列修饰符可以被用在format字符串中：
%M 月名字(January……December)
%W 星期名字(Sunday……Saturday)
%D 有英语前缀的月份的日期(1st, 2nd, 3rd, 等等。）
%Y 年, 数字, 4 位
%y 年, 数字, 2 位
%a 缩写的星期名字(Sun……Sat)
%d 月份中的天数, 数字(00……31)
%e 月份中的天数, 数字(0……31)
%m 月, 数字(01……12)
%c 月, 数字(1……12)
%b 缩写的月份名字(Jan……Dec)
%j 一年中的天数(001……366)
%H 小时(00……23)
%k 小时(0……23)
%h 小时(01……12)
%I 小时(01……12)
%l 小时(1……12)
%i 分钟, 数字(00……59)
%r 时间,12 小时(hh:mm:ss [AP]M)
%T 时间,24 小时(hh:mm:ss)
%S 秒(00……59)
%s 秒(00……59)
%p AM或PM
%w 一个星期中的天数(0=Sunday ……6=Saturday ）
%U 星期(0……52), 这里星期天是星期的第一天
