SQL Server'da önceki ayın ilk ve son gününü (zaman damgasıyla) alma

118

Zaman damgası ile önceki ayın ilk ve son gününü veren çözümü bulamadım. Umarım bu başkalarına yardımcı olur. Bu soruna zaten bir çözüm varsa özür dilerim.

İşte çözüm.

 SELECT DATEADD(month, DATEDIFF(month, -1, getdate()) - 2, 0) as FirtDayPreviousMonthWithTimeStamp,
    DATEADD(ss, -1, DATEADD(month, DATEDIFF(month, 0, getdate()), 0)) as LastDayPreviousMonthWithTimeStamp

Bu, aşağıdakileri döndürür: currentdate = '2012-7-31'

sonuç: 2012-06-01 00:00:00.000 2012-06-30 23:59:59.000

Bu, aşağıdakileri döndürür: currentdate = '2012-1-1'

sonuç: 2011-12-01 00:00:00.000 2011-12-31 23:59:59.000

Günün son saniyesini almak işe yaramaz. Tüm verileri bir ay içinde istiyorsanız,> = 1. gün ve <sonraki ayın 1. günü çok daha kullanışlıdır.

@Thiru Tüm SQL yazılımları DATEDIFF () işlevinde 3 argümana izin vermez. SQL Server'ın yaptığını biliyorum ama MySQL'in yaptığından emin değilim.

Çözüm

Talep ettiğiniz tarih biçimine ODBC biçimi (kod 120 ) denir .

İstediğiniz değerleri gerçekten hesaplamak için aşağıdakileri SQL'inize ekleyin.

Kopyala yapıştır...

DECLARE
    @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))

... ve kodunuzda kullanın:

  • @FirstDayOfLastMonth
  • @LastDayOfLastMonth

Parametrelere başvuran tüm ifadelerden daha önce yapıştırılması gerektiğini unutmayın, ancak bu noktadan itibaren @FirstDayOfLastMonth ve @LastDayOfLastMonth'a başvurabilirsiniz. .

Misal

Şimdi bazı kodları iş başında görelim:

DECLARE
    @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))

SELECT
    'First day of last month' AS Title, CONVERT(VARCHAR, @FirstDayOfLastMonth , 120) AS [ODBC]
UNION 

SELECT 
    'Last day of last month' AS Title, CONVERT(VARCHAR, @LastDayOfLastMonth , 120) AS [ODBC]

Aşağıdaki çıktıyı üretmek için yukarıdaki kodu çalıştırın:

Şekil a

Not: Benim için bugünün tarihinin 12 Eylül 2016 olduğunu unutmayın .

Daha fazla (bütünlük aşkına)

Ortak tarih parametreleri

Daha fazlasını istemeye mi başladın?

Tarihle ilgili daha kapsamlı bir dizi parametre ayarlamak için aşağıdakileri SQL'inize ekleyin: 

DECLARE
    @FirstDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 0))
    , @LastDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 6))
    , @FirstDayOfLastWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 7, GETDATE()), 0))
    , @LastDayOfLastWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 7, GETDATE()), 6))
    , @FirstDayOfNextWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 7))
    , @LastDayOfNextWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 13))
    , @FirstDayOfCurrentMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE() - 1) ), GETDATE()))
    , @LastDayOfCurrentMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 1, GETDATE())) ), DATEADD(m, 1, GETDATE())))
    , @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))
    , @FirstDayOfNextMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 1, GETDATE() - 1)) ), DATEADD(m, 1, GETDATE())))
    , @LastDayOfNextMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 2, GETDATE())) ), DATEADD(m, 2, GETDATE())))
    , @FirstDayOfCurrentYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()), 0))
    , @LastDayOfCurrentYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 1, 0))))
    , @FirstDayOfLastYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) - 1, 0))
    , @LastDayOfLastYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()), 0))))
    , @FirstDayOfNextYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 1, 0))
    , @LastDayOfNextYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 2, 0))))

Bunu daha önce, tercihen prosedürünüzün veya SQL sorgunuzun en üstüne eklemek en mantıklı olacaktır.

Bir kez bildirildikten sonra, parametrelere ihtiyaç duyduğunuz kadar kodunuzun herhangi bir yerinde başvurulabilir.

Ülkeniz kayıpsa, o zaman kodu bilmediğim içindir. Lütfen bu yanıtı düzenleyip ülkenize yeni bir sütun ekleyebilirseniz çok yararlı ve seviniriz.

Şimdiden teşekkürler.

SQL2012'den, adı verilen yeni bir işlev vardır EOMONTH. Bu işlevi kullanarak geçen ayın ilk ve son günü kolayca bulunabilir.

select DATEADD(DD,1,EOMONTH(Getdate(),-2)) firstdayoflastmonth, EOMONTH(Getdate(), -1) lastdayoflastmonth

SSRS raporlarında aşağıdaki mantığı kullandım.

BUS_DATE = 17-09-2013

X=DATEADD(MONTH,-1,BUS_DATE) = 17-08-2013

Y=DAY(BUS_DATE)=17

first_date = DATEADD(DAY,-Y+1,X)=01-08-2013

last_date  = DATEADD(DAY,-Y,BUS_DATE)=31-08-2013

SQL Server'da önceki ayın ilk ve son gününü (zaman damgası ile) çalıştırarak

--select dateadd(dd,-datepart(dd,getdate())+1,dateadd(mm,-1,getdate())) --first day of previous month 
--select dateadd(dd,-datepart(dd,getdate()),getdate()) -- last day of previous month**

Bir ayın 31'i olan bir temel tarih alın, örneğin '20011231'. Sonra
aşağıdaki prosedürü kullanın (Aşağıda 3 aynı örnek verdim, sadece @dt değeri farklıdır).

declare @dt datetime;

set @dt = '20140312'

SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');



set @dt = '20140208'

SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');



set @dt = '20140405'

SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');

İşte oldukça yalın ve dinamik bir yol. Geçen ayın son günü için, geçerli sayısal günü bugünün tarihinden çıkarın. Geçen ayın ilk günü için aynı kodu kullanın, sayısal günü önceki sonuçtan çıkararak tekrarlayın ve 1 ekleyin.

declare @PriorEOM as datetime
declare @PriorFOM as datetime

Set @PriorEOM = dateadd(day,-day(getdate()),getdate())

Set @PriorFOM = dateadd(day,-day(@PriorEOM) + 1,@PriorEOM)

Print @PriorEOM
Print @PriorFOM

Geçen ayın ilk tarihini öğrenmek için:

select DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE())-1, 0) LastMonthFirstDate

Geçen ayın son tarihini öğrenmek için:

select DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) LastMonthEndDate

Bu çözümün sunulduğunu henüz görmedim; daha basit okunabilirliği için tercihim bu:

select dateadd(month,-1,format(getutcdate(),'yyyy-MM-01'))

Bu, önceki ayın ilk gününü almanın bildiğim en basit yolu:

1. Adım: Verileri Postgres'e taşıyın

Adım 2: 

select date_trunc('month', getdate()) - '1 MONTH'::interval;

date_trunc, SQL Server'da kullanılamaz.
