Check if similar to tableFunctions.

function "SAP_INO"."sap.ino.db.basis::f_last_delimited_substring" ( iv_string varchar(1024), iv_delimiter char) 
    returns result varchar(1024)
    language sqlscript
    sql security definer as
begin
    declare lv_delimiter_index int := 0;

    declare lv_index int := 0;
    declare lv_length int := length(:iv_string);

    for lv_index in 0 .. (lv_length -1) do
        if(substring(:iv_string, lv_index, 1) = :iv_delimiter) then 
            lv_delimiter_index := lv_index;
        end if;
    end for;

    result := substring(iv_string, lv_delimiter_index + 1, lv_length - lv_delimiter_index);
end;
