Cómo obtener el primer y último día del mes anterior (con marca de tiempo) en SQL Server

116

No pude encontrar la solución que da el primer y último día del mes anterior con marca de tiempo. Espero que esto ayude a otros. Si ya existe una solución para este problema, me disculpo.

Aqui esta la solucion.

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

Esto devolverá lo siguiente si currentdate = '2012-7-31'

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

Esto devolverá lo siguiente si currentdate = '2012-1-1'

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

Conseguir el último segundo del día es inútil. Si desea todos los datos en un mes,> = día 1 y <día 1 del próximo mes es mucho más útil.

@Thiru No todos los softwares SQL permiten 3 argumentos en la función DATEDIFF (). Sé que SQL Server lo hace, pero no estoy seguro de que MySQL lo haga.

Datediff solo acepta dos argumentos. Obtengo # 1582 - Recuento de parámetros incorrecto en la llamada a la función nativa 'DATEDIFF'

Primer día de la semana actual.

select CONVERT(varchar,dateadd(week,datediff(week,0,getdate()),0),106)

Último día de la semana actual.

select CONVERT(varchar,dateadd(week,datediff(week,0,getdate()),6),106)

Primer día de la semana pasada.

select CONVERT(varchar,DATEADD(week,datediff(week,7,getdate()),0),106)

Último día de la semana pasada.

select CONVERT(varchar,dateadd(week,datediff(week,7,getdate()),6),106)

Primer día de la próxima semana.

select CONVERT(varchar,dateadd(week,datediff(week,0,getdate()),7),106)

Último día de la próxima semana.

select CONVERT(varchar,dateadd(week,datediff(week,0,getdate()),13),106)

Primer día del mes actual.

select CONVERT(varchar,dateadd(d,-(day(getdate()-1)),getdate()),106)

Último día del mes actual.

select CONVERT(varchar,dateadd(d,-(day(dateadd(m,1,getdate()))),dateadd(m,1,getdate())),106)

En este ejemplo, solo funciona el día 31 y no los días restantes.

Primer día del último mes.

select CONVERT(varchar,dateadd(d,-(day(dateadd(m,-1,getdate()-2))),dateadd(m,-1,getdate()-1)),106)

Último día del último mes.

select CONVERT(varchar,dateadd(d,-(day(getdate())),getdate()),106)

Primer día del mes siguiente.

select CONVERT(varchar,dateadd(d,-(day(dateadd(m,1,getdate()-1))),dateadd(m,1,getdate())),106)

Último día del mes siguiente.

select CONVERT(varchar,dateadd(d,-(day(dateadd(m,2,getdate()))),DATEADD(m,2,getdate())),106)

Primer día del año actual.

select CONVERT(varchar,dateadd(year,datediff(year,0,getdate()),0),106)

Último día del año actual.

select CONVERT(varchar,dateadd(ms,-2,dateadd(year,0,dateadd(year,datediff(year,0,getdate())+1,0))),106)

Primer día del año pasado.

select CONVERT(varchar,dateadd(year,datediff(year,0,getdate())-1,0),106)

Último día del año pasado.

select CONVERT(varchar,dateadd(ms,-2,dateadd(year,0,dateadd(year,datediff(year,0,getdate()),0))),106)

Primer día del próximo año.

select CONVERT(varchar,dateadd(YEAR,DATEDIFF(year,0,getdate())+1,0),106)

Último día del año que viene.

select CONVERT(varchar,dateadd(ms,-2,dateadd(year,0,dateadd(year,datediff(year,0,getdate())+2,0))),106)

STYANARA, Muchas buenas funciones, Gracias. ¿A qué se refiere cuando dice "En este ejemplo, solo funciona el día 31. y los días restantes no"? No estoy seguro de entender a cuál te refieres.

Estoy tratando de hacer lo mismo. Esa frase no tiene sentido.

Probé su primer día del mes actual hoy el primer día del mes y regresó el primer día del mes pasado.

No pensar que CONVERT es la mejor solución si CAST está disponible

Solución

El formato de fecha que solicitó se llama formato ODBC (código 120 ).

Para calcular realmente los valores que solicitó, incluya lo siguiente en su SQL.

Copiar pegar...

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()))

... y usa en tu código:

  • @FirstDayOfLastMonth
  • @LastDayOfLastMonth

Tenga en cuenta que debe pegarse antes que cualquier declaración que haga referencia a los parámetros, pero a partir de ese momento puede hacer referencia a @FirstDayOfLastMonth y @LastDayOfLastMonth en su código.

Ejemplo

Veamos un código en acción:

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]

Ejecute el código anterior para producir el siguiente resultado:

Nota: Tenga en cuenta que la fecha de hoy para mí es el 12 de septiembre de 2016 .

Parámetros de fecha comunes

¿Te quedas con ganas de más?

Para configurar un rango más completo de parámetros útiles relacionados con la fecha, incluya lo siguiente en su SQL: 

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))))

Tendría más sentido incluirlo antes, preferiblemente en la parte superior de su procedimiento o consulta SQL.

Una vez declarados, los parámetros pueden ser referenciados en cualquier lugar de su código, tantas veces como los necesite.

Veamos un código en acción:

DECLARE
    @FirstDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 0))

Ejecute el código anterior para producir el siguiente resultado:

Si falta su país, es porque no conozco el código. Sería muy útil y apreciaría si pudiera editar esta respuesta y agregar una nueva columna para su país.

Gracias por adelantado.

Desde SQL2012, se introdujo una nueva función llamada EOMONTH. Con esta función se puede encontrar fácilmente el primer y último día del último mes.

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

He utilizado la siguiente lógica en los informes SSRS.

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

Puede obtener el primer y último día del mes anterior (con marca de tiempo) en SQL Server ejecutando

--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**

Tome alguna fecha base que sea el 31 de algún mes, por ejemplo, '20011231'. Luego use el
siguiente procedimiento (he dado 3 ejemplos idénticos a continuación, solo el valor @dt difiere).

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');

He aquí una forma bastante directa y dinámica. Para el último día del mes pasado, reste el día numérico actual de la fecha de hoy. Para el primer día del mes pasado, use el mismo código, simplemente repita restando el día numérico del resultado anterior y sume 1.

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

Para obtener la primera fecha del mes pasado:

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

Para obtener la última fecha del mes pasado:

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

Todavía no he visto esta solución presentada; esta es mi preferencia por su legibilidad más simple:

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

Esta es la forma más sencilla que conozco de obtener el primer día del mes anterior:

Paso 1: mover datos a Postgres

Paso 2: 

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

date_trunc no está disponible en SQL Server.
