Hi all,
i have an strange result here, i'm using 7.4.2 on redhat 8
i have a query like this
SELECT CPA.rub_codigo, RUB.rub_descripcion, CPA.cpa_valor,
CPA.cpa_fechavencimiento
FROM rec_m_cuadropagos CPA, rec_m_rubro RUB
WHERE RUB.ent_codigo = CPA.ent_codigo AND RUB.rub_codigo = CPA.rub_codigo
AND
CPA.ent_codigo = 1 AND CPA.sec_codigo = 1 AND CPA.ani_codigo =
'2004-2005' AND
CPA.cic_codigo = 1 AND CPA.esp_codigo = 0 AND CPA.cur_codigo = 1 AND
CPA.cur_paralelo = ALL (SELECT cur_paralelo FROM aca_t_curso WHERE
ent_codigo = 1 AND
sec_codigo = 1 AND
ani_codigo = '2004-2005' AND
cic_codigo = 1 AND
esp_codigo = 0 AND
cur_codigo = 1)
that bring no values but if i do this (the same query without the =ALL part)
SELECT CPA.rub_codigo, RUB.rub_descripcion, CPA.cpa_valor,
CPA.cpa_fechavencimiento
FROM rec_m_cuadropagos CPA, rec_m_rubro RUB
WHERE RUB.ent_codigo = CPA.ent_codigo AND RUB.rub_codigo = CPA.rub_codigo
AND
CPA.ent_codigo = 1 AND CPA.sec_codigo = 1 AND CPA.ani_codigo =
'2004-2005' AND
CPA.cic_codigo = 1 AND CPA.esp_codigo = 0 AND CPA.cur_codigo = 1
get a resultset, one would think that the =ALL subquery is filtering out
that rows but the cur_paralelo has same values in both sides
select distinct cur_paralelo from rec_m_cuadropagos WHERE ent_codigo = 1 AND
sec_codigo = 1 AND
ani_codigo = '2004-2005' AND
cic_codigo = 1 AND
esp_codigo = 0 AND
cur_codigo = 1
intersect
SELECT cur_paralelo FROM aca_t_curso WHERE ent_codigo = 1 AND
sec_codigo = 1 AND
ani_codigo = '2004-2005' AND
cic_codigo = 1 AND
esp_codigo = 0 AND
cur_codigo = 1
this query proves that its result is 'A', 'B', 'C'
any idea, is something wrong in my thinking?
thanx in advance,
Jaime Casanova
