Hi, What is the porpose of "groupBy" attribute used in the SQL Mapper doc for "Complex Collection Properties" subject? It says "The important items here are the groupBy="quarter" attribute.." but it doesn't say why. I've tried my own example for 1:M relations and I did not the effect of groupBy attribute clearly. (After a few examples, a new sample doc will come.. :) )
Thanks. -- Ersin
