Anda memerlukan meja dengan jam kerja yang valid, dengan pengecualian akhir pekan dan hari libur (atau ditandai sebagai akhir pekan/libur sehingga Anda dapat melewatinya.) Setiap baris mewakili satu hari dan jumlah jam kerja untuk hari itu. Kemudian Anda menanyakan tabel jam kerja dari tanggal mulai hingga tanggal (menit) pertama di mana jumlah (jam*60) lebih besar dari parameter menit Anda, tidak termasuk baris akhir pekan/liburan yang ditandai. Itu memberi Anda tanggal akhir.
Berikut tabel harinya:
CREATE TABLE [dbo].[tblDay](
[dt] [datetime] NOT NULL,
[dayOfWk] [int] NULL,
[dayOfWkInMo] [int] NULL,
[isWeekend] [bit] NOT NULL,
[holidayID] [int] NULL,
[workingDayCount] [int] NULL,
CONSTRAINT [PK_tblDay] PRIMARY KEY CLUSTERED
(
[dt] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
inilah cara saya mengisi tabel dengan hari:
CREATE PROCEDURE [dbo].[usp_tblDay]
AS
BEGIN
SET NOCOUNT ON;
DECLARE
@Dt datetime ,
@wkInMo int,
@firstDwOfMo int,
@holID int,
@workDayCount int,
@weekday int,
@month int,
@day int,
@isWkEnd bit
set @workDayCount = 0
SET @Dt = CONVERT( datetime, '2008-01-01' )
while @dt < '2020-01-01'
begin
delete from tblDay where dt = @dt
set @weekday = datepart( weekday, @Dt )
set @month = datepart(month,@dt)
set @day = datepart(day,@dt)
if @day = 1 -- 1st of mo
begin
set @wkInMo = 1
set @firstDwOfMo = @weekday
end
if ((@weekday = 7) or (@weekday = 1))
set @isWkEnd = 1
else
set @isWkEnd = 0
if @isWkEnd = 0 and (@month = 1 and @day = 1)
set @holID=1 -- new years on workday
else if @weekday= 6 and (@month = 12 and @day = 31)
set @holID=1 -- holiday on sat, change to fri
else if @weekday= 2 and (@month = 1 and @day = 2)
set @holID=1 -- holiday on sun, change to mon
else if @wkInMo = 3 and @weekday= 2 and @month = 1
set @holID = 2 -- mlk
else if @wkInMo = 3 and @weekday= 2 and @month = 2
set @holID = 3 -- President’s
else if @wkInMo = 4 and @weekday= 2 and @month = 5 and datepart(month,@dt+7) = 6
set @holID = 4 -- memorial on 4th mon, no 5th
else if @wkInMo = 5 and @weekday= 2 and @month = 5
set @holID = 4 -- memorial on 5th mon
else if @isWkEnd = 0 and (@month = 7 and @day = 4)
set @holID=5 -- July 4 on workday
else if @weekday= 6 and (@month = 7 and @day = 3)
set @holID=5 -- holiday on sat, change to fri
else if @weekday= 2 and (@month = 7 and @day = 5)
set @holID=5 -- holiday on sun, change to mon
else if @wkInMo = 1 and @weekday= 2 and @month = 9
set @holID = 6 -- Labor

set @holID = 8 -- thx
else if @holID = 8
set @holID = 9 -- dy after thx
else if @isWkEnd = 0 and (@month = 12 and @day = 25)
set @holID=10 -- xmas day on workday
else if @weekday= 6 and (@month = 12 and @day = 24)
set @holID=10 -- holiday on sat, change to fri
else if @weekday= 2 and (@month = 12 and @day = 26)
set @holID=10 -- holiday on sun, change to mon
else
set @holID = null
insert into tblDay select @dt,@weekday,@wkInMo,@isWkEnd,@holID,@workDayCount
if @isWkEnd=0 and @holID is null
set @workDayCount = @workDayCount + 1
set @dt = @dt + 1
if datepart( weekday, @Dt ) = @firstDwOfMo
set @wkInMo = @wkInMo + 1
end
