my idea is:
1- create a table for storage special caracters,
create table caracteres(
caracter character varying
);
insert into caracteres values(':');
insert into caracteres values(';');
insert into caracteres values('<');
insert into caracteres values('=');
insert into caracteres values('>');
insert into caracteres values('?');
insert into caracteres values('[');
after
2- create a funcion:
create or replace function clean_string(_p_dado character varying)
returns character varying as $$
declare
_v_clean_string character varying := _p_dado;
_c character varying;
begin
for _c in select caracter from caracters loop
_v_clean_string := btrim(_c_clean_string, _c);
end loop;
return _c;
end;
$$ language plpgsql immutable strict;
for make a command
update TABLE set COLUMN = clear_string(COLUMN);
------------------------------------------------------------
atually a had follow error:
create table caracteres(
caracter character varying
);
