Hi Bob

I'm not sure what you mean about querying one table twice -- why  
would you need to do that?

What I was referring to is that having multiple queries on one PHP  
page is (reportedly) slower than having only one PHP query, and  
returning related data via related fields (w/ or w/o portals) on the  
one queried layout.  For instance, having a portal of Child records  
on a Parent's layout, and then just querying the Parent records, is  
faster than querying the Parent records and querying the Children  
records separately.
