분기를 기준으로 기간을 선택하려면 달력 표를 사용하여이를 용이하게 할 수 있습니다. 다음 예제에서는 Creating a date dimension or calendar table in SQL Server - Aaron Bertrand의 발췌 문장을 사용합니다.
-- if regional settings are interfering with interpretation of dates/literals:
/*

create table dbo.Calendar_Example (

, constraint pk_Calendar_Quarters primary key clustered (date)
);
declare @FromDate date = '20160101';

일정 숫자 표 참조 :
여기에서, 당신은 선택에 포함 분기 세트를 전달하는 테이블 반환 매개 변수 (TVP)을 사용할 수 있습니다.예 :
create type dbo.DateRange_udt as table (
FromDate date not null
, ThruDate date not null
primary key (FromDate,ThruDate)
);
go
create procedure dbo.Select_Using_DateRange_udt (
@DateRange dbo.DateRange_udt readonly
) as
begin;
set nocount on;
set xact_abort on;
select *
from MM
inner join @DateRange dr on mm.CDate >= dr.FromDate
and mm.CDate <= dr.ThruDate
end;
go
