Slow report

Question

Hi
I have the next problem:
I have a report on which two of his columns are generated by function and this report is very slow.I made the next tests:
1.When I run the script of the report in DB it is fast .
2.When I remove this two columns the report is fast also (in APEX).

Answer 1

function GET_ANALYSIS(RUN_NUM NUMBER, A_TYPE VARCHAR2 ) return varchar2 is
result varchar2(32767);
begin
result :='<table>';
for i in (select to_char(a.start_date,'dd.mm.yyyy hh24:mi:ss') as start_date, a.id
from tilo_analysis a
where a.run_id = RUN_NUM
and a.type = a_type) loop
result := result||'<tr><td> <span class="class2"><aa href='||apex_util.prepare_url('f?p='||v('APP_ID')
||':23100:'||v('SESSION')||':DO_NOT_CLEAR:'||v('DEBUG')||':23100:TILO_ANALYSE_ID,TILO_LOG_RUN_ID:'||i.id||','||RUN_NUM )||'
title='||i.start_date||'>'||i.start_date||'</a></span></td>'; --DB
result := result||'<td> <span class="class2"><aahref='||apex_util.prepare_url('f?p='||v('APP_ID')
||':27100:'||v('SESSION')||':DO_NOT_CLEAR:'||v('DEBUG')||':27100:TILO_ANALYSE_ID,TILO_LOG_RUN_ID:'||i.id||','||RUN_NUM)||'
title='||i.start_date||'>'||i.start_date||'</a></span></td></tr>'; --SESSION    
end loop;
-- result := result||'<tr><td><input type="button" value="Generate" onclick="doSubmit(''GENERATE_BUTTON'');" id="GENERATE_BUTTON" tabindex="4" class="htmldbButton" /></td></tr>';
result := result||'</table>';
if A_TYPE = 'TILO_ONLINE_ANALYSIS' then
result := result||'<input type="button" value="Generate" onclick="doSubmit(''GENERATE_TILO_ANALYSIS!'||RUN_NUM||''');" id="GENERATE_TILO_ANALYSIS_BUTTON" tabindex="4" class="htmldbButton" />';
end if;
return(Result);
end ;
P.S <aa = <a I made it to escape the link
