Subj:   Re: How to concatenate case expressions
 
From:   Roland Grupe

Philippe,

just add parenthesis around the two case statements and it should work:

select
calendar_date,day_of_month,day_of_year,
(case when day_of_week='1' then 'Dimanche '||trim(day_of_month)
when day_of_week='2' then 'Lundi '||trim(day_of_month)
when day_of_week='3' then 'Mardi '||trim(day_of_month)
when day_of_week='4' then 'Mercredi '||trim(day_of_month)
when day_of_week='5' then 'Jeudi '||trim(day_of_month)
when day_of_week='6' then 'Vendredi '||trim(day_of_month)
when day_of_week='7' then 'Samedi '||trim(day_of_month)
end )

||

(case when month_of_year='1' then 'Janvier '
when month_of_year='2' then 'Février'
when month_of_year='3' then 'Mars'
when month_of_year='4' then 'Avril'
when month_of_year='5' then 'Mai '
when month_of_year='6' then 'Juin'
when month_of_year='7' then 'Juillet'
when month_of_year='8' then 'Ao=FBt'
when month_of_year='9' then 'Septembre'
when month_of_year='10' then 'Octobre'
when month_of_year='11' then 'Novembre'
when month_of_year='12' then 'Décembre'
end )

from sys_calendar.calendar
where extract(year from calendar_date) = '2003' order by calendar_date
