Can someone give an example of singleValueQueryFunction please?

Not sure about how to use the fields.
Can someone give one example?
Thanks.

I was searching for that, too, just now. For me it was helpful to find this page:
http://javadoc.pentaho.com/reporting...yFunction.html

Then it becomes clear that the name of the field you want to read goes into "resultColumn". "Name" is the name you want to give to your field in your report, "Query" is the query to read from.
"Fields" defines which of the values you already have from your default query shall be handed over as parameters. I don't need a parameter, but it seems like it is not allowed to leave this field empty so I just put one in, no matter which one.

All the best,

Axel,
Thanks.
I want to figure out the link from the row of default/main query to the query for that one value.
I read the source code, but could not figure out the way to link the values of main query to parameters of the fields .
