MDX Conditional Sum using role playing date dimensions

Posted By: Posted Date: April 10, 2011 Points: 0 Category :

I have a cube with a single fact: [Measures].[order count] and two roleplaying dimensions [Order Date] and [Shipped Date]

I looking for calculated member that counts the order only if the Order Date and Shipped Date Occur in the same month.

I can do this as a TSQL case statement in the ETL; but I'm curious if there is a MDX based solution?

I'm using MSSAS 2008 R2

Link 1 measure group to 2 different role playing date dimensions and browse it by same date dimensio

hello, I'm Using SQL Server Standard 2008.

I have a measure group Sick leave, which holds measures like sick duration, and number of sick registrations.

For sick duration, the measure group is linked to the Date End role playing dimension by Sick End Date.

For Number of Sick registrations, the measure group is linked to the Date Start role playing dimension by Sick Start date.

But now I want to browse both sick duration and number of sick registrations at the same time against Date dimension,

How to do that?

filtering a role playing dimension

I have a role playing dimension and need to run a query that will select the intersection of members that are common on a single attribute... So Dim1 and Dim2, they both have the attribute [Name] (though the fact table has two different foreing keys mapping to the single primary key on the dimension table) I need to select the members where both foreign keys on the fact table map to the same member in the dimension table so for example, Dim1.Name = 'John Smith' and Dim2.Name = 'John Smith' Any ideas?

Different attribute name in each dimension for a role playing dimension

Is it possible to name the attribute differently in a role playing dimension. For example I use the Date dimension as the role playing dimension for Ship Date and Order Date. When I use these attributes on the report, both of them show as 'Date' which is the name of the attribute in the Date dimension. Is there any work around to implement these names differently?

Calculated Measure Help - Comparing Months from two Date Dimensions

Hello: I have a Measure Group that has two Date dimensions, a Reporting Date and a Fee Paid Date. The Reporting Date and the Fee date is based on the same Dimension, which has a standard YQMD hierarchy. It's very typical. The calculation is called "Fees Paid In Same Period", and it would display the Fees paid if the Reporting Month equals the Fees Paid Month. How do i do this? Thanks,

Previous working date - Time dimensions

Hi all,

I need an mdx to get the previous working day.

I`ve got my complete time dimension, including weekends. Every day member has got a Member Property that says wether it is a working day or not. See table below. Then, I need an mdx expression to return the "Prev working Day". Any idea??

Role playing dimension and member naming question.

I have a fact table with invoice information that has multiple date columns.

I had originaly only needed to join my time dimension to this fact table on it's create date, but I have now added a role-playing dimension to join to the invoice date.

When I had 1 date dimension all of it's members where called 'week','year', 'day', etc.
Now that I have the role-playing dimension I have two dimensions with member names like 'Date.week', 'Date.year', 'Date.day', 'Invoice Date.week', 'Invoice Date.year', 'Invoice Date.day'.

So many queries I had written to reference the original date dimension no longer work because of the extra 'Date.' prefix. Is there a way to hide this prefix for my original date dimension?

Thanks in advance.

Testing for Valid Date or Null Value -- Using Conditional Split

I have a Flat File Source with several columns of data that should be valid dates. Sometimes however they may either be NULL or not valid dates. I understand the expresstion ISNULL([ColumnName]) will test for the NULL condition. What is the syntax to test if the value is a valid date? It might be a string such as "baddate" or it could be a date that is too old. Could you provide an example of an expression that will test for both of these conditions?

Thanks.

Using a CompareValidator to check input is a valid date

The CompareValidator can do more than just compare two controls. You can also compare it against several of the main .net data types such as Date, Integer, Double and Currency.

To do this you would set Operator="DataTypeCheck" and instead of setting the ControlToCompare or ValueToCompare attributes as you normally would you use the Type="Date" (or any of the data types I have listed above).

How To Set a Date Format In GridView Using ASP.NET 2.0

A very common desire is to set a column of a gridview to display just the month, day and year of a DateTime type. The problem is the by default, the HtmlEncode property of the boundfield attribute (
The problem is that if this field is enabled, you can not pass format information to the boundfield control. That is, if you try the following code, you will not get the desired result.

jQuery Date picker Implementation in ASP.NET

I've posted a wrapper ASP.NET around the jQuery.UI Datepickercontrol. This small client side calendar control is compact, looks nice and is very easy to use and I've added it some time back to my control library.

This is primarily an update for the jQuery.ui version, and so I spend a few hours or so cleaning it up which wasn't as easy as it could have been since the API has changed quite drastically from Marc's original implementation. The biggest changes have to do with the theming integration and the resulting explosion of related resources.

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

Using Conditional Split data Transfer in SSIS 2008

This article uses the Integration Services Conditional Split Data Transformation element to filter and transfer data from a set of flat text files to SQL Server database table. The concept can be easily extended to apply to any other source or destination such as Microsoft Excel. This scenario is useful in creating denormalized database tables in a reporting and analysis situation.
