How to extract data for last 1/2 hour?

[Halaku · Accepted solution]

Over the weekend I tried a few things, not pretty and I do not understand it fully but it worked.

Here is what I used to perform the extraction:

UPDATETIME > %sysfunc(datetime())- (60*30)

I still have to understand fully the working of %sysfunc, can any one explain? Is this the right approach?:smileyconfused:

I am using DIS 4.21
