Get Weekstartdate and enddate by date - sql-server-2008

How to get weekstartdate and weekenddate by passing one date ?
When I pass 2016-07-27 01:24:10.510, I need this output
startdate: 2016-07-24 00:00:00.000 which is Sunday
enddate: 2016-07-30 00:00:00.000 which is Saturday
I used this code, but this is returning wrong output
DECLARE #Date DATE = getdate()
SELECT d.WeekStart,
Weekend = CASE WHEN DATEADD(DAY, 7, WeekStart) > StartOfNextMonth
THEN StartOfNextMonth
ELSE DATEADD(DAY, 7, WeekStart)
END
FROM ( SELECT WeekStart = DATEADD(DAY,
((DATEPART(DAY, #Date) - 1) / 7.0) * 7,
DATEADD(MONTH, DATEDIFF(MONTH, 0, #Date), 0)),
StartOfNextMonth = DATEADD(MONTH, DATEDIFF(MONTH, 0, #Date) + 1, 0)
) AS d;
Any Ideas?

Could also be a Table-Valued Function
Declare #Date Date = GetDate()
Select weekstartdate = DateAdd(DD,1-DatePart(DW,#Date),#Date )
,weekenddate = DateAdd(DD,7-DatePart(DW,#Date),#Date )
Returns
weekstartdate weekenddate
2016-07-24 2016-07-30

Assuming that ##DATEFIRST is 7:
declare #Samples as Table ( Sample DateTime );
insert into #Samples ( Sample ) values
( '2016-07-27 01:24:10.510' ),
( '2016-07-20 00:00:00.000' ),
( '2016-07-21 00:00:00.000' ),
( '2016-07-22 00:00:00.000' ),
( '2016-07-23 00:00:00.000' ),
( '2016-07-24 00:00:00.000' ),
( '2016-07-25 00:00:00.000' ),
( '2016-07-26 00:00:00.000' ),
( '2016-07-27 00:00:00.000' ),
( '2016-07-28 00:00:00.000' ),
( '2016-07-29 00:00:00.000' );
select Sample,
DateAdd( day, 1 - DatePart( weekday, Sample ), Cast( Sample as Date ) ) as [StartOfWeek],
DateAdd( day, 7 - DatePart( weekday, Sample ), Cast( Sample as Date ) ) as [EndOfWeek]
from #Samples;

How to conver this SQL server Function into a CTE in snowflake

I have two functions in SQL server that i'm trying to recreate in snowflake. i want to make it a CTE instead as i'm having many issues with it being a function (very picky about date parameters passed through)
I'm not quite thinking of it in the right way. So we pass two paramters through, a date and an int. and the function returns an INT value for us. I'm kind of "stuck".
--Function 1: Straight from SQL server
ALTER FUNCTION [dbo].[cfn_GetShiftIDFromDateTime] (
#dateTime datetime,
#shiftCalendarID int
)
RETURNS int
AS
BEGIN
DECLARE
#time time = CONVERT( time, #dateTime ),
#curDay int,
#prvDay int,
#shiftID int;
SELECT TOP 1
#shiftCalendarID = ID,
#curDay = DATEDIFF( dd, BeginDate, #dateTime ) % PeriodInDays + 1,
#prvDay = ( #curDay + PeriodInDays - 2 ) % PeriodInDays + 1
FROM ShiftCalendar
WHERE ID = #shiftCalendarID
OR ( #shiftCalendarID IS NULL
AND Name = 'Factory'
AND BeginDate <= #dateTime )
ORDER BY BeginDate DESC;
SELECT #shiftID = ID
FROM Shift
WHERE ShiftCalendarID = #shiftCalendarID
AND ( ( FromDay = #curDay AND FromTimeOfDay <= #time AND TillTimeOfDay > #time )
OR ( FromDay = #curDay AND FromTimeOfDay >= TillTimeOfDay AND FromTimeOfDay <= #time )
OR ( FromDay = #prvDay AND FromTimeOfDay >= TillTimeOfDay AND TillTimeOfDay > #time )
);
RETURN #shiftID;
END
--GO
I had help from a user writing this and was able to get this function written in snowflake and seems to be working properly. here it is below
--Function 1 -- Snowflake syntax, currently working
CREATE OR REPLACE FUNCTION DB_BI_DEV.RAW_CPMS_AAR.cfn_GetShiftIDFromDateTime (dateTime TIMESTAMP_NTZ(9), shiftCalendarID int)
RETURNS table (shiftID int)
AS
$$
WITH T0 (ShiftCalendarID, CurDay, PrvDay)
AS (
SELECT TOP 1
ID AS ShiftCalendarID,
DATEDIFF( day, BeginDate, dateTime ) % PeriodInDays + 1 AS CurDay,
( CurDay + PeriodInDays - 2 ) % PeriodInDays + 1 AS PrvDay
FROM RAW_CPMS_AAR.ShiftCalendar
WHERE ID = shiftCalendarID
OR ( shiftCalendarID IS NULL
AND Name = 'Factory'
AND BeginDate <= dateTime )
ORDER BY BeginDate DESC
),
T1 (TimeValue)
AS (
SELECT TIME_FROM_PARTS(
EXTRACT(HOUR FROM dateTime),
EXTRACT(MINUTE FROM dateTime),
EXTRACT(SECOND FROM dateTime))
)
SELECT ID as shiftID
FROM RAW_CPMS_AAR.Shift, T0, T1
WHERE Shift.ShiftCalendarID = T0.ShiftCalendarID
AND ( ( FromDay = T0.CurDay AND FromTimeOfDay <= T1.TimeValue AND TillTimeOfDay > T1.TimeValue )
OR ( FromDay = T0.CurDay AND FromTimeOfDay >= TillTimeOfDay AND FromTimeOfDay <= T1.TimeValue )
OR ( FromDay = T0.PrvDay AND FromTimeOfDay >= TillTimeOfDay AND TillTimeOfDay > T1.TimeValue )
)
$$
;
here is function 2:
--Function 2: Straight from SQL server
ALTER FUNCTION [dbo].[cfn_GetEquipmentShiftCalendarID] ( #equipmentID int, #date datetime )
RETURNS int
AS
BEGIN
IF #date IS NULL SET #date = GETDATE();
DECLARE
#shiftCalendarID int,
#endDate date;
WITH cte ( ID, ParentEquipmentID, ShiftCalendarEntityNumber ) AS (
SELECT ID, ParentEquipmentID, ShiftCalendarEntityNumber
FROM Equipment
WHERE ID = #equipmentID
UNION ALL
SELECT p.ID, p.ParentEquipmentID, p.ShiftCalendarEntityNumber
FROM cte
INNER JOIN Equipment p ON p.ID = cte.ParentEquipmentID AND cte.ShiftCalendarEntityNumber IS NULL
)
SELECT TOP 1 #shiftCalendarID = sc.ID, #endDate = sc.EndDate
FROM cte
INNER JOIN ShiftCalendar sc ON sc.EntityNumber = cte.ShiftCalendarEntityNumber
WHERE sc.BeginDate <= #date
ORDER BY
CASE WHEN EndDate IS NULL OR EndDate > #date THEN 1 ELSE 2 END, -- Prio on date range
sc.BeginDate DESC;
IF #shiftCalendarID IS NULL
BEGIN
-- Default to the last created calendar we find that started before the given time
SELECT TOP 1 #shiftCalendarID = ID
FROM ShiftCalendar
WHERE BeginDate < #date
ORDER BY BeginDate DESC;
END;
RETURN #shiftCalendarID; -- CASE WHEN #endDate IS NULL OR #endDate > #date THEN #shiftCalendarID END; -- Return NULL when no matching date range found?
END
GO
This one I was able to rewrite in snowflake but the if statement isnt working. I am not sure if snowflake function can use an if statement.
ALTER FUNCTION [dbo].[cfn_GetShiftIDFromDateTime] (
#dateTime datetime,
#shiftCalendarID int
)
RETURNS int
AS
BEGIN
DECLARE
#time time = CONVERT( time, #dateTime ),
#curDay int,
#prvDay int,
#shiftID int;
SELECT TOP 1
#shiftCalendarID = ID,
#curDay = DATEDIFF( dd, BeginDate, #dateTime ) % PeriodInDays + 1,
#prvDay = ( #curDay + PeriodInDays - 2 ) % PeriodInDays + 1
FROM ShiftCalendar
WHERE ID = #shiftCalendarID
OR ( #shiftCalendarID IS NULL
AND Name = 'Factory'
AND BeginDate <= #dateTime )
ORDER BY BeginDate DESC;
SELECT #shiftID = ID
FROM Shift
WHERE ShiftCalendarID = #shiftCalendarID
AND ( ( FromDay = #curDay AND FromTimeOfDay <= #time AND TillTimeOfDay > #time )
OR ( FromDay = #curDay AND FromTimeOfDay >= TillTimeOfDay AND FromTimeOfDay <= #time )
OR ( FromDay = #prvDay AND FromTimeOfDay >= TillTimeOfDay AND TillTimeOfDay > #time )
);
RETURN #shiftID;
END

so how are these functions used? i have a view which i was able to recreate in snowflake, but is missing the part that calls the function.
ALTER VIEW [proj].[pvw_PowerBI_ActualUnits]
SELECT
e.Name AS ProductionUnit,
temp.DateTime AS DateTime,
s.Reference AS Shift,
CONVERT(TIME, temp.DateTime) AS Time,
CONVERT(DATE, temp.DateTime - ISNULL((SELECT CAST(MIN(s_first.FromTimeOfDay) AS DateTime) FROM [Shift] s_first WHERE s_first.FromDay = s.FromDay AND s_first.ShiftCalendarID = s.ShiftCalendarID), CAST('6:00' AS DateTime))) AS ProductionDate,
'Actual Units' AS ScrapReason,
temp.ScrapQuantity AS ScrapQuantity,
'Auto Registered' AS RegistrationType,
s.ID
FROM
(SELECT
vl.EquipmentID AS ProductionUnit,
DATEADD(MINUTE, 30 * (DATEPART(MINUTE, vl.BeginTime) / 30), DATEADD(HOUR, DATEDIFF(HOUR, 0, vl.BeginTime), 0)) AS DateTime,
SUM(vl.Quantity) AS ScrapQuantity
FROM oee.ValueLog vl WITH (NOLOCK)
INNER JOIN KPIInstance ki ON ki.ID = vl.KPIInstanceID AND ki.KPIDefinitionID LIKE 'COUNT-OUT:%'
GROUP BY DATEADD(MINUTE, 30 * (DATEPART(MINUTE, vl.BeginTime) / 30), DATEADD(HOUR, DATEDIFF(HOUR, 0, vl.BeginTime), 0)), vl.EquipmentID) temp
INNER JOIN Equipment e ON e.ID = temp.ProductionUnit
INNER JOIN Shift s ON s.ID = dbo.cfn_GetShiftIDFromDateTime(temp.DateTime, dbo.cfn_GetEquipmentShiftCalendarID(temp.ProductionUnit, temp.DateTime)) -- here is where the functions are called
i was able to rewrite this in snowflake for the most part minus calling the function.
SELECT
e.Name AS ProductionUnit,
temp.DateTime AS DateTime,
s.Reference AS Shift,
temp.DateTime::TIME AS Time,
--CONVERT(DATE, temp.DateTime - ISNULL((SELECT CAST(MIN(s_first.FromTimeOfDay) AS DateTime) FROM [Shift] s_first WHERE s_first.FromDay = s.FromDay AND s_first.ShiftCalendarID = s.ShiftCalendarID), CAST('6:00' AS DateTime))) AS ProductionDate,
IFNULL(dateadd(HOUR, - (HOUR(SELECT MIN(s_first.FromTimeOfDay)
FROM RAW_CPMS_AAR.Shift s_first WHERE s_first.FromDay = s.FromDay AND s_first.ShiftCalendarID = s.ShiftCalendarID)), temp.DateTime), (dateadd(HOUR, - 6, temp.DateTime))) AS ProductionDate ,
'Actual Units' AS ScrapReason,
temp.ScrapQuantity AS ScrapQuantity,
'Auto Registered' AS RegistrationType
FROM
(SELECT
vl.EquipmentID AS ProductionUnit,
DATEADD(MIN, 30 * (DATE_PART(MINUTE, vl.BeginTime) / 30), DATEADD(HOUR, DATEDIFF(HOUR, '0', vl.BeginTime), '0')) AS DateTime,
SUM(vl.Quantity) AS ScrapQuantity
FROM RAW_CPMS_AAR.ValueLog vl
INNER JOIN KPIInstance ki ON ki.ID = vl.KPIInstanceID AND ki.KPIDefinitionID LIKE 'COUNT-OUT:%'
GROUP BY DATEADD(MIN, 30 * (DATE_PART(MINUTE, vl.BeginTime) / 30), DATEADD(HOUR, DATEDIFF(HOUR, '0', vl.BeginTime), '0')), vl.EquipmentID) as temp, shiftcalendar_cte, RAW_CPMS_AAR.Equipment e, RAW_CPMS_AAR.Shift s
WHERE e.ID = temp.ProductionUnit
Now i dont know if there is a better way to do this, maybe a cte is better. i know functions are not resource friendly, i'm simply trying to recreate this. open to any ideas or help.
ok, some small translations:
DATEADD(HOUR, DATEDIFF(HOUR, 0, vl.BeginTime), 0)
is truncating to the hour, so is the same as
date_trunc('HOUR', vl.BeginTime)
that dateadd thus is:
select column1
,date_trunc('hour', column1) as t_hour
,truncate(minute(column1)/30)*30
,timeadd('minute', truncate(minute(column1)/30)*30, date_trunc('hour', column1)) as datetime
from values
('2022-11-14 13:26:01'::timestamp_ntz),
('2022-11-14 12:34:01'::timestamp_ntz);
COLUMN1
T_HOUR
TRUNCATE(MINUTE(COLUMN1)/30)*30
DATETIME
2022-11-14 13:26:01.000
2022-11-14 13:00:00.000

2022-11-14 12:30:00.000
So moving that sub-select that you alias as temp into a CTE, and get that "working"
WITH table_oee_valuelog(equipmentid, begintime, quantity, kpiinstanceid) as (
select * from values
(1, '2022-11-14 13:26:01'::timestamp_ntz, 10, 100),
(1, '2022-11-14 13:26:01'::timestamp_ntz, 11, 100),
(1, '2022-11-14 13:34:01'::timestamp_ntz, 12, 100)
), table_kpiinstance(id, kpidefinitionid) as (
select * from values
(100, 'COUNT-OUT:extra stuff')
)--, temp_sub_select as (
SELECT
vl.equipmentid as productionunit,
timeadd('minute', truncate(minute(vl.BeginTime)/30)*30, date_trunc('hour', vl.BeginTime)) as datetime,
SUM(vl.quantity) AS scrapquantity
FROM table_oee_valuelog as vl
INNER JOIN table_kpiinstance as ki
ON ki.ID = vl.KPIInstanceID
AND ki.KPIDefinitionID LIKE 'COUNT-OUT:%'
GROUP BY 1,2

implementing cfn_GetEquipmentShiftCalendarID
so if we extend our table data a bit more we can take a first crack at cfn_GetEquipmentShiftCalendarID like:
WITH table_oee_valuelog(equipmentid, begintime, quantity, kpiinstanceid) as (
select * from values
(1, '2022-11-14 13:26:01'::timestamp_ntz, 10, 100),
(1, '2022-11-14 13:26:01'::timestamp_ntz, 11, 100),
(1, '2022-11-14 13:34:01'::timestamp_ntz, 12, 100)
), table_kpiinstance(id, kpidefinitionid) as (
select * from values
(100, 'COUNT-OUT:extra stuff')
), table_equipment(id, name, parentequipmentid, shiftcalendarentitynumber) as (
select * from values
(1,'equipment one', 2, null),
(2,'equipment two', null, 80),
(3,'equipment three', 4, 81),
(4,'equipment four', null, 82)
), table_shift(id, shiftcalendarid, reference) as (
select * from values
(1001, 9001, 'a')
), table_shiftcalendar(id, entitynumber, begindate, enddate) as (
select * from values
(699, 80, '2021-01-01'::date, '2021-12-31'::date),
(700, 80, '2022-01-01'::date, '2022-12-31'::date),
--(701, 81, '2022-02-01'::date, '2022-11-30'::date),
(702, 82, '2022-10-01'::date, '2022-11-15'::date)
), cte_GetEquipmentShiftCalendarID/*(id, shiftCalendarID)*/ as (
with recursive rec_cte (id, parentequipmentid, shiftcalendarentitynumber) as (
select
ID,
ParentEquipmentID,
ShiftCalendarEntityNumber
FROM table_equipment
UNION ALL
SELECT
r.ID,
p.ParentEquipmentID,
p.ShiftCalendarEntityNumber
FROM rec_cte as r
INNER JOIN table_equipment p
ON p.ID = r.ParentEquipmentID
AND r.ShiftCalendarEntityNumber IS NULL
)
select * from rec_cte as c
left join table_shiftcalendar as sc
on sc.entitynumber = c.ShiftCalendarEntityNumber
where shiftcalendarentitynumber is not null
qualify row_number() over (partition by c.id order by sc.begindate desc ) = 1
)
select * from cte_GetEquipmentShiftCalendarID;
This is missing the #date based filters and the catch all, as to product the "latest" all bit of equipment, cannot be done yet.

so we need to weave this current data, with the temp table, how convenient we made it a CTE already...
so the next partial step is:

from temp_sub_select as t
left join cte_GetEquipmentShiftCalendarID_part_a as c

last step of this function can be handled with this CTE which we can join to the prior results, and take if the prior results are null.
select

sc.id
from (

join table_shiftcalendar as sc

qualify row_number() over (partition by t.datetime order by sc.begindate desc) = 1

Snowflake Function input is datetime, but when i call the function it's not quite working

with temp AS (

sreas.Name AS ScrapReason,

when i run this query above, i get Processing aborted due to error 300010:391167117; incident 3245754.. I believe this is an issue with the temp.datetime -- when i run the same codebut hardcoding the function input, i get the desired output.

it seems that that somwehere along the line, it's not liking the date format i put in. it's not returning me an error of not liking the input.

altering a table using sql

I have this table
**Original Table**
year month duration amount per month
2012 5 3 2000
and I want to get this
**Result table**
year month duration amount per month
2012 5 1 2000
2012 6 1 2000
2012 7 1 2000
Note how the duration of a project (this is a project) is 3 and the "amount per month" is 2000, so I added two more rows to show that the next months (6 and 7) will have an "amount per month" as well. How do I do that with sql/tsql?
try this for SQL SERVER, i included my test temp table:
declare #temp as table
(
[year] int
, [month] int
, [duration] int
, [amount] int
)
insert into #temp
(
[year]
, [month]
, [duration]
, [amount]
)
VALUES(
2012
,5
,3
,2000
)
SELECT
[year]
,[month] + n.number
,1
,[amount]
, '1' + SUBSTRING(CAST([duration] AS varchar(10)), 2, 1000) AS Items
FROM #temp
JOIN master..spt_values n
ON n.type = 'P'
AND n.number < CONVERT(int, [duration])
Please see the script below that may work for your requirement. I have also compensated for calender year and month increment. Please test and let me know.
DECLARE #temp AS TABLE([Year] INT,[Month] INT,Duration INT,Amount INT)
INSERT INTO #temp([year], [month], Duration, Amount)
VALUES (2011, 5, 3, 2000),(2012, 11, 3, 3000),(2013, 9, 12, 1000);
;WITH cte_datefix
AS (
SELECT [Year],
[Month],
Duration,
Amount,
CAST(CAST([Year] AS VARCHAR(4)) + RIGHT('00' + CAST([Month] AS VARCHAR(2)), 2) + '01' AS DATE) AS [Date]
FROM #temp
),
cte_Reslut
AS (SELECT [Year],
[Month],
Duration,
Amount,
[Date],
1 AS Months
FROM cte_datefix
UNION ALL
SELECT t.[Year],
t.[Month],
t.Duration,
t.Amount,
DATEADD(M, Months, t.[Date]) AS [Date],
cr.Months + 1 AS Months
FROM cte_Reslut AS cr
INNER JOIN cte_datefix AS t
ON t.[Year] = cr.[Year]
WHERE cr.Months < cr.Duration
)
SELECT YEAR([Date]) AS [Year],
MONTH([Date]) AS [Month],
1 AS Duration,
Amount
FROM cte_Reslut
ORDER BY [Date]
For those that are wondering how to increment the year if needed, here is an example building on Suing response (really easy, just include two case statements):
select
2012 as [year]
,11 as [month]
,5 as [duration]
,2000 as [amount]
into #temp
select * from #temp
SELECT
case
when [month] + n.number > 12
then [year] + 1
else [year]
end as [year]
,case
when [month] + n.number > 12
then [month] + n.number - 12
else [month] + n.number
end as newYear
,1 as newDuration
,[amount]
, '1' + SUBSTRING(CAST([duration] AS varchar(10)), 2, 1000) AS Items
FROM #temp
JOIN master..spt_values n
ON n.type = 'P'
AND n.number < CONVERT(int, [duration])
drop table #temp

Creating a calendar in sql

We use a lookup table in a database for grouping weeks, months and years. Sadly the chap who created it has long since gone and the calendar runs out at the end of the year! So I really need to find a way of adding to it! Its set up with the following columns:
I'm not very good in sql(MS2008) to be honest and ive stuggeled with it, we cant set anything new up as everything is built around this!
you can do smth like this, but I don't get why your calendar starts from March?
declare #Date_Start date, #Date_End date
select #Date_Start = '20130101'
select #Date_End = '20131231'
;with
CTE_Dates as (
select #Date_Start as [Date]
union all
select dateadd(dd, 1, [Date])
from CTE_Dates
where [Date] < #Date_End
),

select
[Date],
datename(dw, [Date]) as [Day],
datepart(ww, [Date]) as [Week],

Deleting rows based on date comparison - sql

I'm writing a SQL script to remove some rows from my table.
I need to remove the rows that have a certain type (easy), where the valuation timestamp is 16:00 on the current day when the create date is less than 4pm. Does that make sense?
delete from cfo_daily_trans_hist where dh_dd_type_id = 'valuation' --and dh_val_time_stamp is today at 16:00 where the dh_create_dt is today at a time earlier than 16:00
I just don't really know the syntax to do that exact date comparison.
DELETE [dbo].[cfo_daily_trans_hist]
WHERE [dh_dd_type_id] = 'valuation'
AND [dh_val_time_stamp] = DATEADD(HH, 16, CONVERT(DATETIME,CONVERT(DATE,GETDATE()))) -- is today at 16:00
AND [the dh_create_dt] < DATEADD(HH, 16, CONVERT(DATETIME,CONVERT(DATE,GETDATE())))-- is today at a time earlier than 16:00
And dh_val_time_stamp = DateAdd(Hour, 16, DateAdd(Day, DateDiff(Day, 0, GetDate()), 0))
And dh_create_dt >= DateAdd(Day, DateDiff(Day, 0, GetDate()), 0)
And dh_create_dt < DateAdd(Hour, 16, DateAdd(Day, DateDiff(Day, 0, GetDate()), 0))
