hi all,
i was trying to migrate some data into a new structure i created. so i
execute this exact query:
insert into rec_t_ordenpago("ent_codigo", "sec_codigo", "ani_codigo",
"orp_numero", "orp_tipopersona", "orp_persona", "cic_codigo",
"esp_codigo","cur_codigo", "cur_paralelo", "rub_codigo", "orp_valor", "orp_fechaemision",
"orp_fechavencimiento", "ban_codigo",
"cta_numero", "est_codigo")
select cua.ent_codigo, cua.sec_codigo, cua.ani_codigo, (select (nvl(max(orp_numero), 0) + 1) from
rec_t_ordenpago), 'AL', alcu.alu_codigo, cua.cic_codigo, cua.esp_codigo,
cua.cur_codigo, cua.cur_paralelo, cua.rub_codigo, cua.cpa_valor, current_date, cua.cpa_fechavencimiento,
null,null, 'PE' from rec_m_cuadropagos cua, aca_t_alumnocurso alcu
where cua.ent_codigo = 1 and alcu.ent_codigo = cua.ent_codigo and alcu.sec_codigo = cua.sec_codigo and
alcu.ani_codigo = cua.ani_codigo and alcu.cic_codigo = cua.cic_codigo and alcu.esp_codigo = cua.esp_codigo and
alcu.cur_codigo = cua.cur_codigo and alcu.cur_paralelo = cua.cur_paralelo
but i ended up with duplicate key error then i replace the (select
(nvl(max(orp_numero), 0) + 1) from rec_t_ordenpago) part with
nextval('seq1') and that work.
So my question is, is this a postgreSQL limitation or is the way it have to
happen? why?
thanx in advance,
Jaime Casanova
