[Resolved] operations on dates into Xquery, how to do that ?

Question

hi,
Now that I found how to perform Xqueries :) I want to know how to make operations and calculs on dates. My query look like that:
SELECT XMLQuery('
for $i in ora:view("CATALOGUE")
where $i/ROW/CONT_CAT/CATALOGUE/DATE_DEBUT <= current-date()
and $i/ROW/CONT_CAT/CATALOGUE/DATE_FIN >= current-date()
and $i/ROW/CONT_CAT/PROGRAMME/DATE_EFFET < (current-date() + P5D)
and $i/ROW/CONT_CAT/PROGRAMME/DATE_EFFET > current-date()
and $i/ROW/ID_CAT != 8
and $i/ROW/ID_CAT != 9
return <liste><CAT>{$i/ROW/CONT_CAT/CATALOGUE/Prom/CODE_ART}</CAT>
<PROG>{$i/ROW/CONT_CAT/PROGRAMME/Prom/CODE_ART}</PROG></liste>'
RETURNING CONTENT) AS cato FROM DUAL;
unfortunatly (current-date() + P5D) doesn't work nor things like :
current-date() + dayTimeDuration("P5D")
or even like :
add-daytimeduration-date(current-date() + dayTimeDuration("P5D"))
I just want to add some days to the current-date but I don't know how.
If anybody could help I'll be very pleased.
:) thanks

You need to use xdt namespace prefix for dayTimeDuration
xdt:dayTimeDuration("P5D")
Also be aware, the latest xquery spec has moved dayTimeDuration() into xs namespace
prefix, so in the future, you need to use
xs:dayTimeDuration("P5D") instead.
Try
SELECT XMLQuery('
for $i in ora:view("CATALOGUE")
where $i/ROW/CONT_CAT/CATALOGUE/DATE_DEBUT <= current-date()
and $i/ROW/CONT_CAT/CATALOGUE/DATE_FIN >= current-date()
and $i/ROW/CONT_CAT/PROGRAMME/DATE_EFFET < (current-date() + xdt:dayTimeDuration("P5D"))
and $i/ROW/CONT_CAT/PROGRAMME/DATE_EFFET > current-date()
and $i/ROW/ID_CAT != 8
and $i/ROW/ID_CAT != 9
return <liste><CAT>{$i/ROW/CONT_CAT/CATALOGUE/Prom/CODE_ART}</CAT>
<PROG>{$i/ROW/CONT_CAT/PROGRAMME/Prom/CODE_ART}</PROG></liste>'
RETURNING CONTENT) AS cato FROM DUAL;
