There's a one-to-many relationship between px_items.id and contacts.id, and I
want a printout of some data from each.
I want to print out the query results px_items.id field once and once only, but
the contacts.notes field many times, as there could be many entries.
Right now it prints out each row, which is workable for now, but could get
annoying. I'm trying for something like
entry one
note a
note b
note c
entry two
note a
entry three
notb a
note b
Here's my schema and code:
