How to get Oracle Form Parameter Value into Oracle Report

Question

Hi,
Please guide for the following:
On a form, there is one Control Block (CB1), having two TEXT ITEMS, namely From_Date & To_Date respectively. The user inputs from and to dates, for example From_Date: 01-JAN-2009 and To_Date: 31-DEC-2009 and then press "Print Report" button.
I want to get From_Date & To_Date in the report, as per below mentioned heading:
SALES REPORT
From: 01-JAN-2009 To: 31-DEC-2009
Regards,

Answer 1

You can use ADD_PARAMETER builtin,
The following example creates a parameter List, adds two parameters to it, and then passes the List to a form by way of the CALL_FORM procedure:
<pre>
/** Declare a variable of type ParamList to store ** the parameter List ID */
DECLARE
PARAM_ID ParamList;
BEGIN
/* ** Create a parameter List named "input_params" */
PARAM_ID := Create_Parameter_List('input_params');
/* ** Add two parameters to the List to pass values for each user-defined parameters defined in the target form; for each parameter, specify its key, type (text or data), and value */
Add_Parameter(PARAM_ID, 'FROM_DATE'', TEXT_PARAMETER, to_char(:CB1.From_Date, 'DD-MON-RRRR'));
Add_Parameter(PARAM_ID, 'TO_DATE', TEXT_PARAMETER, to_char(:CB1.To_Date, 'DD-MON-RRRR'));
/* ** Now call the report, referencing the parameter List ID ** in the last argument to the report calling procedure */
END;
</pre>
