Within a PL/SQL procedure, wrap a query or refcursor in HTML table

Question

It seems really easy if you are using SQL*Plus to use

SQL> set markup html on;

and get some lovely results to the SQL*Plus window. we

Answer 1

One option is to use hypertext functions HTF:

set define off

create table so14t (id number, data varchar2(25));

insert all
into so14t values(101, 'one hundred & one')
into so14t values(202, 'two hundred & two')
into so14t values(303, 'three hundred & three')
select 1 from dual;

declare
  v_html varchar2(32767);
begin
  v_html := htf.tableopen;

  for i in (select * from so14t) loop
    v_html := v_html || htf.tablerowopen;
    v_html := v_html || htf.tabledata(i.id);
    v_html := v_html || htf.tabledata(htf.escape_sc(i.data));
    v_html := v_html || htf.tablerowclose;
  end loop;

  v_html := v_html || htf.tableclose;

  dbms_output.put_line(v_html);
end;
/

Prints (formatted for readability):

101
one hundred & one
        
202
two hundred & two
        
303
three hundred & three
