Power Pivot :: Cumulative Total For Current Week Days And Previous Week
Nov 30, 2015We are trying to compare our current calendar week (based on Monday being the first day of the week) with the previous calendar week.
I'm trying to produce a line chart with 2 axis:
- x axis; the day of the week (Mon, Tues, Wed etc - it is fine for this to be a # rather than text e.g. 1 = Mon, 2 = Tues etc)
- y axis; the cumulative number of orders
The chart needs two series:
Previous Week. The running count of orders placed that week.
Current Week. The running count of orders placed this week.
Obviously in such a chart the 'Current Week' series is going not going to have values along the whole axis until the end of the week. This is expected and the aim of the chart is to see the current week compares against the previous week for the same day.
I have two tables:
Orders TableCalendar Table
The calendar table's main date column is [calDate] and there are columns for the usual [calWeekNum], [calMonth] etc.
My measure for counting orders is simply; # Orders: = countrows[orders].
How do I take this measure and then work out my two series. I have tried numerous things such as adapting TOTALMTD(), following articles such as these:
- [URL] ...
- [URL] ...
But I have had no luck. The standard cumulative formulas do work e.g. if I wanted a MTD or YTD table I would be ok, it's just adjusting to a WTD that is causing me big issues.

Create A Yesterday, This Week, Last Week Calculated Member
May 23, 2007Hi all,
I'd like to add a yesterday dimension member to a new dimension, like a "Time Utility" dimension, that references the second last day of non empty data in a cube.
At the moment, I'm doing this:
Code Snippet
create member [MIA DW].[DATE TIME].[Date].[Yesterday]
as [DATE TIME].[Date].&[2007-01-01T00:00:00]
select [Measures].members on 0,
non empty [DATE TIME].[Date].members on 1
from [MIA DW]
But the [yesterday] member does not seem to belong to [DATE TIME].[Date].members?
So I guess there's two questions:
1) Can I have a new empty dimension which contains all these special members like "Yesterday" or "This Week" and "Last Week" (these last two obviously refer to a set of Dates)
2)How come the Yesterday member is not returned by the .members function?
Thanks

ISO Year Week Day Of Week Function
Jan 18, 2006Function F_ISO_YEAR_WEEK_DAY_OF_WEEK returns the ISO 8601 Year Week Day of Week in format YYYY-W01-D for the date passed. W01 represents the week of the year from W01 through W53, and D represents the day of the week with 1 = Monday through 7 = Sunday.
The first week of each year starts on the first Monday on or before January 4 of that year, so that the year begins from December 28 of the prior year through January 4 of the current year.
This code creates the function and demos it for the first day, first date+60, and first date+364 for each ISO week/year from 1990 to 2030.

Jun 7, 2001I am trying to convert a field that has a Date and Time in smallDateTime format into something that will give me the day of the week that each Date corresponds to. For example, if my Date/Time field says "Jun 7 2001 09:30:00" I want my Day field to automatically say "Thursday". Is there a function that will do this? Or is there something close that will convert a variable of smalldatetime format into a number 0-6 which then can be converted to a day of the week?

Date Of First Day In Week
Apr 27, 2005I need to write a user defined function that will return the date of the first day of a week when provided with the week number. I had an idea of using a while loop with that will keep adding 1 day from January 1st until the week number (found via the DATEPART function) is equal to the supplied week number. Not sure if this is the best way though - any ideas?

Week Groupings
Jul 26, 2007Hi all,
I have this code below and it appears to work, but I wondered if there was a better way.
Basically I have a table with some sales. The amount sold is stored in a varchar (for a very stupid reason) called ticketNo, the date of the sale is stored in txDate (thankfully this is a date).
We need to report out the total amount sold for a period in weekly groupings with the week starting on Monday. If a week starts within the period specified but does not finish we extend the period to include the whole week.
As I said the code below appears to work (no I have not tested extensively), but it looks like it will be pretty resouce intensive.
Any suggestions?
declare @minTxDate DateTime
declare @maxTxDate DateTime
set @minTxDate = '02-Jul-2007'
set @maxTxDate = '31-Aug-2007'
declare @StartOfYear DateTime

declare @WeekDay int
declare @StartWeek int

How To Get Week Of The Month?
Apr 19, 2004This seems like a difficult one ..
I am trying to calculate the number of the week within a month of a given date. in other words, given a date I need to find out whether it's the 1st week or 2nd or 3rd or 4th or 5th week of that given month.
for instance let's call my function "weekOfMonth()":
weekOfMonth(4/19/2004) should return 4 (it's the fourth week of april)
weekOfMonth(4/7/2004) should return 2 (it's the second week of april)
etc ..

View 20 Replies View RelatedGet Next Friday Of Week
May 22, 2008I want to make a function which returns the next Friday, given a day in the week. I can't find a solution which works. For example:
Input -> Output
4/22/08 -> 4/23/08
4/23/08 -> 4/23/08
4/24/08 -> 4/30/08
I can't find a solution which works. According to one website, this should do it:
DECLARE @Friday DATETIME
SET @Friday = '20000107'
SELECT DATEADD(day, ((DATEDIFF(day, @Friday, GETDATE()) / 7) * 7), @Friday)
Date Of First Day Of Week
May 26, 2008I'm wanting to see if there is a simpler way to accomplish the retrival of the first day of the week Date. What I currently have is:
CASE
WHEN DATEPART(DW, GETDATE()) = 1 THEN DATEADD([D], - 7, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 2 THEN DATEADD([D], - 8, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 3 THEN DATEADD([D], - 9, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 4 THEN DATEADD([D], - 10, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 5 THEN DATEADD([D], - 11, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 6 THEN DATEADD([D], - 12, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 7 THEN DATEADD([D], - 13, GETDATE()) END AS StartWeek1
I'm trying to figure if there might be an easier way to code this. Thanks.

Group By Week?
Mar 30, 2006I want to group my data by "week of". That is for each date, I want to group the data by the Monday of the week that the date falls on.
I have tried using:
SET DATEFIRST 1
SELECT WEEK = DATEADD(day, -1 * DATEPART (dw, ProductionDate), ProductionDate), ProductionDate
FROM tbHollowcoreBedSchedule
which I apparently don't understand. Any help on this? I need to group by the Monday, the above does what I want but groups by the Sunday.
I tried seting DATEFIRST = 2 but this seems to set WEEK to the previous monday.
Any suggestions?

End Of Week Function
Apr 15, 2006This script creates a scalar function, F_END_OF_WEEK, that returns the end of week date for a passed date and a passed start day of week.
Parameter @DATE can be any valid datetime. Parameter @WEEK_START_DAY must be an integer in the range 1 through 7, with Sun = 1, Mon = 2, Tue = 3, Wed = 4, Thu = 5, Fri = 6, and Sat = 7.
This function is a companion to function F_START_OF_WEEK and has the same input parameters, @DATE and @WEEK_START_DAY. If they are called with the same input parameters, they will return the first and last day of the week.
Function F_END_OF_WEEK will return a null if the end of week day would be later than 9999-12-31.
The test code at the end of the script uses function F_START_OF_WEEK which can be found on this link:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=47307
The test code at the end of the script uses function F_TABLE_NUMBER_RANGE which can be found on this link:
