I always get null result with :

case c.descr
when '' then a.desmov
else a.desmov ||'
'||  c.Descr end as Descreg


when c.descr is null and a.desmov is not null ?

I tried :
case (Cast(c.descr as varchar(60)))
when '' then a.desmov
else a.desmov ||'
'||  c.Descr end as Descreg

but same result.

Thanks
