Week Number

Jan 23, 2008

Hi all!

I'm working on a report that will look like this.

WeekNb - Item - QtySold
1 - Item1 - 25
1 - Item2 - 6
2 - Item1 - 10
2 - Item3 - 73
etc...

I use this function to get the week number DATEPART(wk, transactionDate)

But now I have a problem,

Lets says I want the sells for 2008.

The 1st of January is a Tuesday, but I also want the sells that I made on the 31st of December 2007 as it's on the 2008 1st week (monday).

How can I get this to work ?

Help please

Regards,

Or Tho

Convert Week Number To Date Of 1st Day Of That Week...

Feb 2, 2008



I'm looking for a way to convert the [week number, year] back to the date for the 1st day of that week.

Example (assuming DATEFIRST has been set to 1) : Week 3, 2008 = January 14, 2008

Is there a SQL function that will do this?


Thanks,
Mike

Week Number Conversion

Aug 29, 2002

I am working with Week Numbers and was wondering if there is a way to display Week 1 as 01.

The problem that I am having is that when I list the weeks from Week 1 to Week 12 is that the sorting is 1, 10, 11, 12, 2, 3 and I would like to get it to look like 01, 02, 03....09, 10.


Thanks......

Transact SQL :: Get Week Number From DateTime Field?

Aug 21, 2015

Any easier way to do what I am trying, without having a table with all the dates and week numbers.

Scenario: Week number of a DateTime Field where the year does not start on January 01<sup>st</sup> but April 1<sup>st</sup> to 31 Mach.

Issue: A week always starts on a Monday so if the 1<sup>st</sup> is on Tuesday, the first week is Tuesday – Sunday, if the 1<sup>st</sup> April is on Friday, the 1<sup>st</sup> week is Friday – Sunday and 7 day periods from there.

CREATE
TABLE [dbo].[DailyCanx](     
[ID] [int] IDENTITY(1,1)
NOT NULL,     
[DateCancelled] [datetime] NULL
)
ON [PRIMARY]

[code]....

I could create a table with all the start date and end dates of all the week numbers but I think there must be a better way. using SQL Server 2008 R2.

Can anybody tell me to How to get the week number of a specific Date in SQL Server 2005.

Like : say Date "03/01/2008" belongs to the 1st week of the year 2008, same way "21/02/2008" is 8th week of the year 2008.

So, the same way I need to know the week number of a given (variable) date.

Power Pivot :: Cumulative Total For Current Week Days And Previous Week

Nov 30, 2015

We 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, 2007

Hi 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

Greg

ISO Year Week Day Of Week Function

Jan 18, 2006

Function 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.

Day Of The Week

Jun 7, 2001

I 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?

Limitations In Term Of Number Of Tasks And Number Of Columns

Jun 5, 2007

Hi,

I am currently designing a SSIS package to integrate data into a data warehouse fact table. This fact table has about 70 columns among which 17 are foreign keys for dimension tables.

To insert data in that table, I have to make several transformations and lookups. Given the fact that the lookups I have to make are a little complicated, I have about 70 tasks in my Data Flow.
I know it's a lot, but I can't find a way to make it simpler. It seems I really need all these tasks.

Now, the problem is that every new action I try to make on the package takes a lot of time. At design time, everything is very slow. My processor is eavily loaded each time I change a single setting in one of the tasks, and executing the package in debug mode takes for ages. If I take a look at the size of my package file on disk, it's more than 3MB.

Hence my question : Are there any limitations in terms of number of columns or number of tasks that can be processed within a Data Flow ?

If not, then do you have any idea why it's so slow ?

Thanks in advance for any answer.
