SQL按照日、周、月、季度、年统计数据的方法

方式一：

--按日
select sum(consume),day([date]) from consume_record where year([date]) = '2006' group by day([date])

--按周quarter
select sum(consume),datename(week,[date]) from consume_record where year([date]) = '2006' group by datename(week,[date])

--按月
select sum(consume),month([date]) from consume_record where year([date]) = '2006' group by month([date])

--按季
select sum(consume),datename(quarter,[date]) from consume_record where year([date]) = '2006' group by datename(quarter,[date])

--按年
select sum(consume),year([date]) from consume_record where group by year([date])

方式二：

sqlserver 截取日期年份和月份使用datepart函数,函数使用方法如下：

一、函数功能：DATEPART() 函数用于返回日期/时间的单独部分，比如年、月、日、小时、分钟等等。

二、语法：DATEPART(datepart,date)

三、参数说明：date 参数是合法的日期表达式。datepart 参数可以是下列的值：

四、实例

1、截取年份：datepart(yy,'2017-1-1') 返回：2017

2、截取月份：datepart(mm,'2017-1-1') 返回：1

五、datepart函数返回的是整型数值，如果需要返回字符型，那么使用datename()函数,用法与datepart相同，只是返回数据类型不同。

常见错误

--选择列表中的列 'dbo.v_yjdatealljg.cjrq' 无效，因为该列没有包含在聚合函数或 GROUP BY 子句中。
--把所有按组排序的依据都加上 yjxzqid, cjdd, ncpid, YEAR([cjrq]), month([cjrq])
--去掉农产品名称 ncpmc
SELECT yjxzqid, cjdd, ncpid, YEAR([cjrq]) as [year], month([cjrq]) as [month], avg( ttjg)as ttjg, avg(pfjg)as pfjg, avg(lsjg)as lsjg
FROM dbo.v_yjdatealljg group by yjxzqid, cjdd, ncpid, YEAR([cjrq]), month([cjrq])

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
%u 星期(0……52), 这里星期一是星期的第一天
%% 一个文字“%”。
