NWB Queue: Number of Records
« on: October 03, 2017, 04:28:39 AM »
Hi Guys,

Is there a way to display the total number of records in a NWB (displayed and not displayed) in the Heading field of the NWB?

Sure, you can put anything you like in the header.
So all you need to do is;

a) create a small procedure or routine to loop through the view, counting the number of records that are in the result set. This may be a tad expensive from a time point of view, especially for TPS. For SQL you might rather construct a Prop:Sql statement to count the items in a result set.

b) use this procedure to prime a variable, or use it directly in the header.

Of course if you change the browse filter then you will need to re-calculate this number and refresh the header.

Personally I think the "cost" of calculating this number is too high.

Thanks Bruce, the cost of counting was part of my thinking as well.

I was hoping that the NWB would keep tally of the number of records while processing the records for the queue.

I am using a TPS database.

there is no queue.

And even if there was, if it's page-loaded it just loads one page and then stops.
