Re: order by query wrong result

Hi,

I find this workaround:

CREATE OR REPLACE FUNCTION cleanup(text)
RETURNS text AS $$
SELECT replace(replace(replace($1, ' ','x'),'-','x'),'.','x')
$$ LANGUAGE sql;

and I get correct result :

select name
from prva
where name ilike 'savino del bene s%'
order by upper(cleanup(name));
