Hi folks!
Why does the following query work on pgsql 7.2.3 and not in pgsql 7.3.4?
SELECT cronograma_evento.nr_projeto ,cronograma_evento.dt_inic
,cronograma_evento.nr_sala ,cronograma_evento.tm_hora_inicial
,cronograma_evento.tm_hora_final ,cronograma_evento.cd_turma
,cronograma_evento.cd_discipl ,locais_sala.cd_tipo_sala
FROM
cronograma_evento, locais_sala
WHERE
cronograma_evento.dt_crono = '1/12/2003'
AND cronograma_evento.cd_local = ''
AND cronograma_evento.cd_local = locais_sala.cd_local
AND cronograma_evento.nr_sala = locais_sala.nr_sala
ORDER BY
cronograma_evento.nr_sala,
cronograma_evento.tm_hora_inicial;
>\\\!/< 55 11 5080 9258

Success usually comes to those
who are too busy to be looking for it.
