Hello,

I have a simle UDT defined which I am using as a Work Order tracking System.  I have a column for the Date the job was entered (let's call it Date).

What I need to do is to be able to calculate the age of the record (in days), based on the difference between the date entered, and the current system date.  In VB, I would do a Datediff("d",Date,Now()).  I have tried creating a calculated field in the table, and putting an expression of datediff("d",Date,[DateTime:Now]) and get an error message saying the function is not defined.

Is there another way this can be achieved?  I am using UDT Version 3.4.0.

Regards

Steve Teece

UDT's calculated column is based on datacolumn.expression, and unfortunately it doesn't support any Date functions. We realized this limitations and, as we can't add new functions inside, we are able to tweak in a different  way.

Let's say your UDT has a column "Date". Behind the scences UDT has already creaded two additional columns: Date_UDT_Value which contains the localized date as string and  Date_UDT_Ticks which is the long integer representation of your Date and build into the .Net framework.

The calculated column can also refer some tokens that are injected at runtime.

So the expression you ask for is:

([Ticks:Now] - [Date_UDT_Ticks]) / [Ticks:TicksPerDay]

Hi Stefan,

Thanks for the expression - it works perfectly and is exactly what I was trying to achieve.
