Moin,
I try to concat values from three fields in a function like this:
create or replace function
fconcat_name(varchar, varchar, varchar) returns varchar as '
declare
ttl alias for $1;
vnm alias for $2;
nme alias for $3;
begin
return ttl || '' '' || vnm || '' '' || nme;
end;
' language plpgsql;
That works but if one of the fields is empty there are to much
spaces in the result. Is there any alternative to a monster
if-then construct?
Many thanks
Matthias
