*** placeholder use ***

Question

Hi ,
I am using Repors Developer. I try using PlaceHolder. I explaore the example
from the Reports Developer Help. It is the following:
Placeholder for Special Summary example
Suppose that you wanted to create a master/detail report that would list the
highest paid employee(s) for each department. The output below shows a sample
of what you would get:
Dname ACCOUNTING Loc NEW YORK Highest Paid
Employee(s):
Ename Job Sal
CLARK MANAGER 2450.00 KING
KING PRESIDENT 5000.00
MILLER CLERK 1300.00
Dname RESEARCH Loc DALLAS Highest Paid
Employee(s):
Ename Job Sal
SMITH CLERK 800.00 SCOTT and FORD
JONES MANAGER 2975.00
SCOTT ANALYST 3000.00
ADAMS CLERK 1100.00
FORD ANALYST 3000.00
To get the names of the highest paid employee(s), you create a placeholder
column named HIGHEST_PAID_EMP of Datatype Character. The value of
HIGHEST_PAID_EMP is set by a formula column named SET_HIGHEST_PAID_EMP of
Datatype Character. R_COUNT is a summary column with a Function of Count.
SET_HIGHEST_PAID_EMP contains the following PL/SQL function in Formula:
function set_plch_high_emp return character is
begin
/* Check if we are at first record in child, if so,
then reset placeholder */
if (:r_count <= 1) then
:highest_paid_emp := ' ';
end if;
/* Does this child record compare to the max sal
for the dept ? If yes, and placeholder already
set (i.e. we have more than one max sal) set the
placeholder to the concatenated string. Else
set the placeholder to the employee's name */
if (:sal = :max_dept_sal) then
if (:highest_paid_emp <> ' ') then
:highest_paid_emp := :highest_paid_emp||' and '
||:ename;
else
:highest_paid_emp := :ename;
end if;
end if;
return (:highest_paid_emp);
end;
The variable :max_dept_sal is not defined. Where I will be defined and what is
its code.
many Thanks.

Hello
Votre nom me rappelait quelque chose mais sans plus de précision.
Apple met à notre disposition des Guides utilisateurs fort bien faits, encore faut-il les télécharger.
C'est en tous les cas la solution lorsque l'on a acheté un numéro de série pour débrider la version d'essai.
Je ne sais pas ce qu'il en est de la version DVD.
Il existe 18 versions localisées, 7 guides. Sauf erreur, ça fait 126 PDFs se baladant entre 100 Ko et 16 Mo.
Ce serait du délire de mettre ça dans l'image disque téléchargeable.
