i'm using spagobi with oracle DBMS but when i want to get values where year between 2010 and 2014 a got error : right parenthesis missing
select (sum(d.taux_depot *100)/count(r.trimestre) ) as taux , trimestre as trimestre
from datamart_cnss d , ref_temps r
where d.ID_TEMPS = r.ID_TEMPS
and (case when $P{anneecnss}=123 then (r.annee between 2010 and 2014 ) else $P{anneecnss} end) = r.annee
and (case when To_CHAR($P{regimecnss})=123 then To_CHAR(d.id_regime) else To_CHAR($P{regimecnss}) end) = To_CHAR(d.id_regime)
and (case when To_CHAR($P{bureau_cnss})=123 then To_CHAR(d.id_bureau) else To_CHAR($P{bureau_cnss}) end) = To_CHAR(d.id_bureau)
group by trimestre
order by trimestre asc
Thank you

This is not a valid construct:
case when $P{anneecnss}=123 then (r.annee between 2010 and 2014 ) else $P{anneecnss} end
You cannot have a condition inside the then part, just a value or expression that you can then compare with something else.
To apply that filter selectively you don't need to use a case statement, use and and or; I think this is equivalent:
where d.ID_TEMPS = r.ID_TEMPS
and (($P{anneecnss} = 123 and r.annee between 2010 and 2014)
or ($P{anneecnss} != 123 and $P{anneecnss} = r.annee))
and ($P{regimecnss} = 123 or To_CHAR($P{regimecnss}) = To_CHAR(d.id_regime))
and ($P{bureau_cnss} = 123 or To_CHAR($P{bureau_cnss}) = To_CHAR(d.id_bureau))
