is there a size limitation to a dictionary? (want to know in general for
future purposes)
is there consequential extra overhead if using the dictionary method?
thanks

of course, its an
it's just a matter of ordering by the parent and then the child. Once you
get a resultset similar to
parent.id | parent.style | child.id | child.name
1 yellow 4 foo1
1 yellow 5 bar1
1 yellow 6 baz1

I get the ordering but parent appears redundantly.
Do I iterate through loop checking for change in parent.id so parent only
gets displayed first time?
if parent.id != previous_parent_id
display this specific parent.id one time only
previous_parent_id = parent.id ## am resetting the

is it better to issue two separate queries returning a set with 2 records
and 10 respectively or to fetch a joined set (and massage it later on) that
extracts 20 records ? There's no answer to that except that the two
possibilities are entirely doable. Cardinality of the sets comes into play,
did you mean I only need the second query? I know it already extracts data
that query one has, but I didn't know how to iterate using only the second
one and not redundantly display the parent values.

so you have a problem with python, not the database!
if you're not loop-proficient, massage it first to a dictionary, then
loop over it
from collections import defaultdict
resultset = defaultdict(list)
for row in parents_and_childs:
resultset[row.parent_record.id].append(row)
then you can
10 matches
