Re: Fault with initcap

Hi,
Yes, this can be adaptable, and i did simple version of this.
It just split text words with find spaces, capitalise each
pieces(word) and merge together again.
This is a quick and simple work. You can develop over it about your needs.

Try that and tell us about result.

CREATE OR REPLACE FUNCTION initcap2(text)
RETURNS text
LANGUAGE plpgsql
AS $function$
DECLARE
sentence TEXT := '';
word_array TEXT[];
word TEXT;
word_out TEXT;
BEGIN
sentence := $1;

IF sentence is NULL THEN
RETURN NULL;
END IF;

word_array := regexp_split_to_array($1, E'\\s+');
FOREACH word IN ARRAY word_array
LOOP
word_out := upper(left(word, 1)) || lower(substring(word, 2));
sentence := regexp_replace(sentence, word, word_out);
END LOOP;

RETURN trim(sentence);
END;
$function$
;
