I guess that you tried to use it exactly like that: xxx := DBMS_RANDOM.VALUE, but didn't work. So, you could try to create a stored function which will return a random value, and then call this function from the form.

:block.item:= round(dbms_random.value (Min_Value,max_value));
For Ex:
:block.item:= round(dbms_random.value (1, 15));

"FUNCTION F_RANDOM" suggests that you created it in form. Did you? If so, you didn't quite understand what I was saying: you need to create a stored function, the one that is in the database, not in a form. You'd do that in SQL*Plus (or any other tool you use to access the database):
SQL> CREATE OR REPLACE FUNCTION F_RANDOM
  2  RETURN NUMBER IS
  3    V_RANDOM NUMBER;
  4  BEGIN
  5    V_RANDOM := round(dbms_random.value(1, 15));
  6    return V_RANDOM;
  7  END;
  8  /

Function created.

SQL> select f_random from dual;

  F_RANDOM
----------
        12

SQL>

So you'd, basically, call this function in your PL/SQL code; something like
SQL> declare
  2    l_random_val number;
  3  begin
  4    l_random_val := f_random;
  5
  6    dbms_output.put_line('Random value = ' || l_random_val);
  7  end;
  8  /
Random value = 8

PL/SQL procedure successfully completed.
Of course, Forms don't use DBMS_OUTPUT package so you'd do *something* with that value (whatever you plan to do).

Hi,

dbms_random.value must be uesd in the database.I originally thought that it can be used in Forms.


dbms_random.value package must be use in the Form6i or 10g version.

The Following Code is Written in WHEN-BUTTON-PRESSED
trigger is successfully work.
Begin	
:CONTROL.RANDOM_NUMBER:= round(dbms_random.value (1, 15));
End;


I think u have face another problem.

Regards,

Tamzidul Amin.
