Problem counting dinamic column!

Question

Hi,
I am trying to make something like a statistic of a table.
i have a table :
table(M) {
column(priority) data = hight ,medium, low
column(departement) = departement A, departement B, departement C
column(id_message)} = 1, 2 ,3 ..............
i wanted to creat a report output like this:
------------------------Hight---------Medium--------Low---------- Total
departement A ------1---------------2----------------2--------------5
departement B-------3---------------3----------------1--------------7
departement C-------2---------------2----------------2--------------6
with this code i obtain this output, but it is a static solution, that only works for 3 types of priorities and i nedd a dinamic solution
select department,
count(decode(priority,'high',id_message,null)) high,
count(decode(priority,'medium',id_message,null)) medium,
count(decode(priority,'low',id_message,null)) low,
count(id_message) Total
from m
group by department
order by department
can i make something like this:
create or replace function statistic_dep_prior
return clob
is
declare
i number;
j number;
begin
for i in 0..dp_id_departament loop
for j in 0..id_priority loop
count(id_ticket) departement,
end loop;
end loop;
count(id_ticket) Total
from V_TICKET
group by dp_id_departament
order by dp_id_departament
return('
<table>
<tr>
<td>Departament</td>
<td>Hight</td>
</tr>
<tr>
<td>Dep. A</td>
<td>10</td>
<td>20</td>
</tr>
</table>
end;
Thank´s
Pepe

What you appear to be trying to do likely will work far better using a pipelined table function.
Try this:
EXPLAIN PLAN FOR
SELECT table_name
FROM user_tables;
SELECT * FROM TABLE(dbms_xplan.display);
[pre]
If that kind of control over formatting an output looks good then check out the demos here:

asktom.oracle.com and the docs at http://tahiti.oracle.com are also great resources for learning about them.
