Question

我想從日曆和日期中填寫表格dim_Date（idDate，日期，年，月，三個月，週數，周，日），格式爲「year/month/day hh：mm can你請幫我 最好的問候

Answer 1

我做了一些假設，因爲你沒有說什麼格式的日期格式是在（我假設一個varchar），你沒有指定週數和周是...所以我假設一個月的年份和週週：

-->set up data for example 
create table dummy_date_table 
(dummy_date varchar(50)) 
go 
-->insert dummy data(assuming you have these somewhere as text?) 
insert into 
dummy_date_table (dummy_date) values 
('2010/11/01 01:22'), 
('2013/06/02 03:16'), 
('2012/07/03 05:32'), 
('2011/01/04 06:04') 
go 

-->create date dimension based on your logic 
create table dim_Date(
idDate int, -->pk 
date datetime, -->full date 
year int,-->year of date 
month int,-->month of date 
trimester int,-->trimester 1,2,3 
weekNumber int,-->week number in year 
week int, -->week number in month 
day int --.day part of date 
) 

go 

-->used for primary key|date|year|month|trimester|weeknumber|week|day 
declare @i int=1, @date datetime, @year int, @month int, @trimester int, @weeknumber int, @week int, @day int 
-->cursor to insert our data 
declare date_inserter cursor for 

select 
convert(datetime,left(dummy_date,10)), 
datepart(year,convert(datetime,left(dummy_date,10))), 
datepart(month,convert(datetime,left(dummy_date,10))), 
case 
    when datepart(month,convert(datetime,left(dummy_date,10))) <5 then 1 
    when datepart(month,convert(datetime,left(dummy_date,10))) >4 and datepart(month,convert(datetime,left(dummy_date,10))) <9 then 2 
    else 3 
end, 
datepart(ISO_WEEK,convert(datetime,left(dummy_date,10))), 
DATEDIFF(week, DATEADD(MONTH, DATEDIFF(MONTH, 0, convert(datetime,left(dummy_date,10))), 0), convert(datetime,left(dummy_date,10))) +1 , 
datepart(day,convert(datetime,left(dummy_date,10))) 
from 
dummy_date_table; 

open date_inserter; 

fetch next from date_inserter into 
    @date, 
    @year, 
    @month, 
    @trimester, 
    @weeknumber, 
    @week, 
    @day 

    WHILE @@FETCH_STATUS = 0 
    BEGIN 

insert into dim_Date 
select @i, @date, @year, @month, @trimester, @weeknumber, @week, @day 
set @i+=1; 

fetch next from date_inserter into 
    @date, 
    @year, 
    @month, 
    @trimester, 
    @weeknumber, 
    @week, 
    @day 
END 
-->Cleanup 
CLOSE date_inserter 
DEALLOCATE date_inserter 
go 
-->Look at data 
select * from dim_Date 

結果：

idDate date     year month trimester weekNumber week day 
1  2010-11-01 00:00:00.000 2010 11  3   44   1  1 
2  2013-06-02 00:00:00.000 2013 6  2   22   2  2 
3  2012-07-03 00:00:00.000 2012 7  2   27   1  3 
4  2011-01-04 00:00:00.000 2011 1  1   1   2  4
