Hello folks,
When retrieving the data from a RDBMS, would you JOIN the relations, thus
producing several tuples for each person with one different country each? By
sorting appropriately (e. g.on person's PK) and adding some lines of code,
one could achieve the goal. However, there's some overhead (memory, network)
for the data that is processed several times.
(If this is the wrong newsgroup, could you please point me to another one?)
TIA,
Matthias
