Question about LogMiner Viewer GUI

783956Aug 9 2010 — edited Aug 10 2010

Good evening,

I wanted to start the LogMiner Viewer GUI (which the Concepts book says is part of Enterprise Manager).

I could not find anything in Enterprise Manager that seemed to be the LogMiner Viewer GUI. (could have missed it)

After a little Googling, I found this:

oemapp.bat lmviewer

I've searched everywhere and there is no oemapp.bat anywhere on my machine.

I've searched the download area of Oracle thinking that maybe it was something that I needed to download. Did not find such a thing. (found lot of documentation though)

The question: How do I get the LogMiner Viewer GUI ? (I am running Windows XP Pro SP2 - 32bit, Oracle 11gR2)

Thank you for your help,

John.

Thanks for the reply

But i cant use static code. As i said answer count may change in the cell. In my example there are 5 answers but this can be 3 for NFORM_ID = 10. So its not static.

Etbin

But i cant use static code.

Then you need a function which would read a row from your table, count the number of colons in vanswers, generate the appropriate query, execute it and return the string of averages.
Will try to post a sketch just in case it may suit you.

Regards

Etbin

function averages return varchar2 is

  nanswers number;
  the_sql varchar2(32767) := q'{to_char(avg(to_number(substr(vanswers,1,instr(vanswers,':',1,1) - 1))))||':'||}';
  ret_val varchar2(4000);

begin

  select length(vanswers) - length(replace(vanswers,';',''))
    into nanswers
    from tform_results
   where rownum = 1;

  for i in 1 .. nanswers - 1
  loop
    the_sql := the_sql ||
               q'{to_char(avg(to_number(substr(vanswers,
                                               instr(vanswers,':',1,}' || to_char(i) || q'{) + 1,
                                               instr(vanswers,':',1,}' || to_char(i + 1) || q'{) - instr(vanswers,':',1,}' || to_char(i) || q'{) - 1
                                              ))))||':'||
                 }';
  end loop;

  the_sql := the_sql ||
             q'{to_char(avg(to_number(substr(vanswers,instr(vanswers,':',1,}' || to_char(nanswers) || q'{) + 1)))) "AVG"
               }';

/*  dbms_output.put_line(the_sql);  -- while testing check if the_sql is well formed before executing it */

  execute immediate the_sql into ret_val;

  return ret_val;

end;

A nice one (a proof that avoiding list use does have it's drawbacks -> thinking of dynamic sql too soon)

I like recursive with clause and ListAgg and using nested agg function B-)

with tform_results(id,vanswers,nform_id) as (
select 1,'12:3:5:6:7',2 from dual union all
select 2,'13:2:3:2:4',2 from dual union all
select 3,'10:8:1:3:4',2 from dual union all
select 4,'19:4:6:3:7',2 from dual),
rec(vanswers,extStr,LV) as(
select vanswers,RegExp_Substr(vanswers,'[^:]+',1,1),1
  from tform_results
union all
select vanswers,RegExp_Substr(vanswers,'[^:]+',1,LV+1),LV+1

Well, you missed it is has to be grouped by nform_id, so "full" version would be something like:

with tform_results(id,vanswers,nform_id) as (
                                             select 1,'12:3:5:6:7',1 from dual union all

Hi,

I have a table as TFORM_RESULTS. And a column VANSWERS in that table. I keep the answers in that column as like "12:3:5:18". Simply my table data is like this:
The reason that i keep data un-normalized is maybe VANSWERS may change. In this example we have 5 answers but for NFORM_ID = 6 we may have 8 answers. But for the same FORM_ID we have equal answer count.

Which is exactly why you should normalize your data. There is no reason to keep this kind of data unnormalized. The number of rows might be different but the structure of the data will stay.

btw: Did you have a look at the table design of the "knowledge testing" packaged apex application? It might just give you all the table structure that you are looking for.
