Two dates ranges

Question

Hi Guys,
I have a problem here:
For example
SELECT
emp.id_employe,
taux.id_taux,
emp.nom_emp,
emp.prenom_emp,
taux.taux_tc,
per.periode_debut_tc,
per.periode_fin_tc,
fac.id_facture,
fac.periode_debut_fac,
fac.periode_fin_fac
FROM dtp_spe_factures fac
join dtp_spe_commandes com on COM.ID_COMMANDE = FAC.ID_COMMANDE
join dtp_spe_ao_consortiums con on CON.ID_AO_CONSORTIUM = COM.ID_AO_CONSORTIUM
join dtp_spe_taux_categories taux on TAUX.ID_AO_CONSORTIUM = CON.ID_AO_CONSORTIUM
join dtp_spe_categories cat on CAT.ID_CATEGORIE = TAUX.ID_CATEGORIE
join DTP_SPE_TAUX_PERIODE per on PER.ID_TAUX_PERIODE = TAUX.ID_TAUX_PERIODE
join dtp_spe_employes2 emp on EMP.ID_AO_CONSORTIUM = con.ID_AO_CONSORTIUM and CAT.ID_CATEGORIE = EMP.ID_CATEGORIE
PROBLEM
The first 4 lines
1471     11015     Joe     Billy     82.84     2010-04-01     2011-03-31     4474     2009-12-14     2010-04-29

It supposed to return me just the lines 1 and 4
I tried to use this
periode_debut_fac between periode_debut_tc AND periode_fin_tc
and
periode_fin_fac between periode_debut_tc AND periode_fin_tc
But not worked !! The only way that it worked was when I put this select inside another select, but after it the select get time to execut.
Thanks

The model
http://ericyuri.wordpress.com/?attachment_id=423
the full code is this:
-- THIRD select
-- SELECT TAUX_TC FROM ( ...
select
NOM_EMP||', '||PRENOM_EMP ||' P-'|| SEQ AS D,
id_view
from (
SELECT ROW_NUMBER () OVER (PARTITION BY id_ao_consortium ORDER BY id_ao_consortium) id_view,
emp.id_employe,
taux.id_taux,
ROW_NUMBER () OVER (PARTITION BY emp.id_employe ORDER BY taux.id_taux) SEQ,
emp.nom_emp,
emp.prenom_emp,
emp.date_debut_emp,
emp.date_fin_emp,
emp.id_ao_consortium,
taux.id_categorie,
taux.taux_tc,
per.periode_debut_tc,
per.periode_fin_tc,
con.num_ao,
con.nom_con,
com.id_commande,
com.code_commande_com,
fac.id_facture,
fac.periode_debut_fac,
fac.periode_fin_fac
FROM dtp_spe_factures fac
join dtp_spe_commandes com on COM.ID_COMMANDE = FAC.ID_COMMANDE
join dtp_spe_ao_consortiums con on CON.ID_AO_CONSORTIUM = COM.ID_AO_CONSORTIUM
join dtp_spe_taux_categories taux on TAUX.ID_AO_CONSORTIUM = CON.ID_AO_CONSORTIUM
join dtp_spe_categories cat on CAT.ID_CATEGORIE = TAUX.ID_CATEGORIE
join DTP_SPE_TAUX_PERIODE per on PER.ID_TAUX_PERIODE = TAUX.ID_TAUX_PERIODE
join dtp_spe_employes2 emp on EMP.ID_AO_CONSORTIUM = con.ID_AO_CONSORTIUM and CAT.ID_CATEGORIE = EMP.ID_CATEGORIE
where id_facture = :P28_ID_FACTURE
where
periode_debut_fac between periode_debut_tc AND periode_fin_tc
or
periode_fin_fac between periode_debut_tc AND periode_fin_tc
order by 1
-- WHERE ID_VIEW = :P28_ID_VIEW
It is working and fast now ..... the problem is when I try to select another things based on id_view ...
if I want to select another thing for example TAUX_TC... I have to use another select, so it gonna be 3 Select :S
I'd like to known just one way more elegant with performance to do it !! It is working but its wierd for me :P !!
