Acess Datasets programatly

smgomes

It's possible know wich fields are being used by report throught rptdesign?

Example:

In my Dataset i have 30 fields, but i only drag 3 fields to report to iterate in Table Component.

I'am using DataNucleus, and i need to know wich fields the report really uses to obtain better performance in DataNucleus query.

My idea is:

Ask to rptdesign programatly wich fields are in body of report.
It's possible?

Thanks.

Hi smgomes,

You can figure out the fields that are in a table by checking how many columns there are:

this.getRowData().getColumnCount();

and then loop through the different columns with a while statement grabbing the column names with:

this.getRowData().getColumnName(int column);

Not sure if this will work for you application, but it's a way to know which fields are used in a table.
