Master-detail automatic query

How to query the detail block in a
master-detail form when I change
any master key field?
null

This is not implemented, after you update a record you must click on "Save" button and query again.

Oracle Forms : Master Detail : Cannot query detail block

MY requirement is: when user enters records in master block, the corresponding records should be displayed in the detail block. (Detail block is just for viewing).
Master block is a database block based on a custom table. All fields are enetereble in this block.
Detail block is a a database block based on view which is built joining the custom table(on which master block is built) & a standard table. None of the fields in detail block are editable. they are just display only. For detail block, set the Key Mode=Non-Updatable, Enabled a field as Primary Key.
I have created a relation between the 2 blocks. (Deferred=No, AutoQuery=No, Delete Record Behaviour=Isolated.). There is a join between master table & this view.
But when I enter record in master block & save. the detail block records are not displayed. (Message : No Navigable Items in Detail Block).
Yes, there are no navigable items in detail block, because its just for viewing purpose. How can this be achieved.
Thanks,
Naveen

Thanks for your inputs. I got the solution for this. Earlier all items in the block were DISPLAY_ONLY. Now, I have selected them as TEXT_ITEMS (even though they are not updatable). It is working fine now. Thanks.

Master/Detail query problem

I have two VO, masterVo and detailVo, which assoicated with a VL.
I create a page to query the masterVo and show the result master data and related detail data.
Can I add a query criteria to filter the detailVo?
Now I can only set where clauses in masterVo, is it possible to set where clauses both in masterVo and detailVo?

I don't use query region for my master/detail data query, because the query result is in hgrid region on the other page.
So I use controller to send the query criteria into AM for query. In masterVoImpl.java, I combine query
criteria to Where clauses to initiate query. I have one query criteria belong to detailVo attr, How can I put the detailVo criteria
and masterVo query criteria at one query?
Thanks a lot.

Master Detail Query automatic query ..Urgent help

In my last question, I asked about how to automatically query a form based on table or master detail and gota good answer. What I actually need to do is also query on the detail, for example
select a.user_id, b.week_ending,b.mon_hrs,b.tues_hrs
from emp_profile a, time_reporting_week b
where user_id = portal30.wwctx_api.get_user
and week_ending = '02-JAN-02'
and a.user_id = b.user_id
So I know that I can query on master table which is emp profile, but I also need to query on week ending which is in detail. Do I change the clause in my form pacjage?Or should I change something in Additional Pl/sql ??

There are two ways to achieve this. Both methods have some drawbacks, so please go through them and choose the one that suits you.
Method 1:
=========
This method does not require altering the form package.
Assumptions : The detail table has a column named WEEK_ENDING.
Steps :-
1> Edit the form and select the query button in the left frame of the master section.
2> For the pl/sql button event handler, choose the action as Query and replace the default code with the following :-
declare
l_where varchar2(4000);
l_where_pre varchar2(4000);
l_where_post varchar2(4000);
l_where_pos integer;
l_week_ending varchar2(4000);
l_lang varchar2(4000);
begin
p_session.get_shadow_value(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_WEEK_ENDING',
p_index => 1,
p_value => l_week_ending,
p_language => l_lang);
doQuery;
if l_week_ending is not null then
l_where := p_session.get_value_as_varchar2(
p_block_name => 'DEFAULT',
p_attribute_name => '_DETAIL_WHERE_CLAUSE',
p_index => 1
l_where_pos := instr(l_where,' WHERE ');
l_where_pre := substr(l_where,1,l_where_pos+6);
l_where_post := substr(l_where,l_where_pos+7);
l_where_post := 'week_ending = '||l_week_ending||' and '||l_where_post;
l_where := l_where_pre || l_where_post;
p_session.set_value(
p_block_name => 'DEFAULT',
p_attribute_name => '_DETAIL_WHERE_CLAUSE',
p_value => l_where,
p_index => 1);
QueryDetail(
p_mode => 'QUERY' ,
p_session => p_session);
end if;
end;
3> Click on OK to finish editing the form.
4> Run the form - enter query criteria for the master fields and enter the week-ending criterion in the 1st detail
field under Week Ending. Click the Query button.
Advantage:
You will not lose your changes even if you edit the form later on.
Drawback:
In this method, the querying process will be bit slow as we are querying for the detail records twice.
Once through onQuery and the second time after constructing the new where clause with the additional conditon
for the detail rows.
Method 2
========
This method requires altering the form generated package.
Steps :-
1> In the form package, you will find a onQuery procedure. Towards the end of the procedure, you will find a statement like
"_detail_where_cond" := "_detail_where_cond" || ' WHERE ' || ...
2> As the name of the variable suggests, this where condition will be used while querying the detail block. You need to
add a new clause to this for the week_ending column. Prior to that you need to fetch the shadow value for A_WEEK_ENDING.
3> Your altered code should look something like :-
p_session.get_shadow_value(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_WEEK_ENDING',
p_index => 1,
p_value => l_week_ending,
p_language => l_lang);
if l_week_ending is not null then
"_detail_where_cond" := "_detail_where_cond" || ' WHERE WEEK_ENDING = ' || l_week_ending || ' AND ' || --existing code
else
--- use the original code here
"_detail_where_cond" := "_detail_where_cond" || ' WHERE ' || ...
end if;
4> Compile the package body and run the form.
Advantage:
In this method we will be querying the detail rows just once. Unlike in method 1.
Disadvantage:
You will lose your alterations once you create a new version of the form by editing it. You need to recompile the package
after re-introducing your changes.

Master Detail Form - How 2 update a field in the Detail form using a query?

Hello,
I have a master detail form with, each master record having a fixed(6) number of detail records. One of the fields in the detail record is the PART_DESCRIPTION field. I am trying to update this field by querying Table_X. TABLE_X is in the format of (desciption id, description). Description id runs from 1 to 6.
When the form displays, the PART_DESCRIPTION field for the 6 detail records needs to be automatically populated with the six values of description stored in Table_X. How can this be done?
Tried using session storage objects, but made no headway.
Would greatly appreciate pointers on how to go about doing this.
Thanks.
Dev

If you are on a Portal Version lesser than 3.0.9.8.3, then please try the following to populate
the PART_DESCRIPTION field.
Steps:-
1> Edit the form and go to the Additional PL/SQl section and put the following code in the
"...after displaying the page area" :-
declare
type t_vc_arr is table of varchar2(4000) index by binary_integer;
l_arr_desc t_vc_arr;
l_form_name varchar2(200);
l_form_state varchar2(500);
begin
l_form_name := p_session.get_module().get_name();
l_form_state := p_session.get_value_as_varchar2(
p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_FORM_STATE'
if l_form_state = 'QUERY_AND_SAVE' then
select description
bulk collect into l_arr_desc
from <schema>.table_x;
htp.p('
<script>
var descArr = new Array();
var Fidx = 1;
var formObj = document.WWVM'||p_session.get_id()||';
var fieldName = "'||l_form_name||'.DETAIL_BLOCK.PART_DESCRIPTION.0";
for i in 1..l_arr_desc.count loop
htp.p('descArr['||to_char(i-1)||']="'||l_arr_desc(i)||'";');
end loop;
htp.p('
for (var i=0; i < formObj.length; i++){
if (formObj.elements.name == fieldName+Fidx){
formObj.elements[i].value = descArr[Fidx-1];
++Fidx;
htp.p('</script>');
end if;
end;

Master-Detail Form - implementing some thing like Post-Query trigger

Hi all,
I am struggling to implement an eqivalent of a post-query trigger in Oracle Forms. Please bear with me as I am trying to explain in detail what the problem is.
Here is my situation.
I have three tables EMP, DEPT and LOCATION. I created a Master/Table pages on EMP and DEPT.
Basic relationships.
Each LOCATION has one or more DEPTs; Each DEPT is at one and only one LOCATION.
Each DEPT has one ore more EMPs; Each EMP is assigned to only and only DEPT.
Not getting too complicated, here are the table layouts:
LOCATION:
ID number(10,0) not null,
NAME varchar2(20) not null
DEPT
ID number(10,0) not null,
NAME varchar2(20) not null,
LOC_ID number (10,0) not null foreign key from LOCATION
EMP
ID number(10,0) not null,
NAME varchar2(20) not null,
DEPT_ID number (10,0) not null foreign key from DEPT
Assume I have all the constraints, BIU triggers, sequences defined properly.
I am using the APEX page wizard to create a Master/Detail Form on DEPT and EMP. The first page is the Master Report on DEPT. I want to display the Location Name on this page also. Because the Master Report allows
you to change the query, I was able to add the Location Name as part of the
query. This was very simple.
Select a.name "Department_Name",
b.name "Location"
from dept a, location b
where a.loc_id = b.id
Moving on, In the Master Detail Form, I would like to get the Location Name as part of the first Region (Dept Region).
In this region, I would like to include the Location Name also. So my first region on the Master Detail form includes:
Dept Id: ________
Dept Name: _______
Location Name: __________
As Region are automatically populated using using a Fetch Row from EMP table (Automated Row Fetch) on an After Header process point, I don't have a way of including the Location as part of query. So I created a Region level Item called Location Name, made it Display only.
In the old SQL*Forms, or Oracle Forms days, I used to use a Post-Query trigger, or Post-Change trigger to fire on the Loc_Id column to populate the Location Name. Simple fetch like:
Select name
into :P80_location_name
from location
where loc_id = :P80_loc_id
However, I am struggling to implement some thing simple like this in APEX. Tried creating a processes, computatations etc, but nothing is working.
I have seen some previous responses to fetching values from a foreign table
using a button or AJAX script, but this should be very basic. What am I
missing here?
Appreciate any insights.
Thanks.
John

Hi John,
I'm not too familiar with the post-query triggers in Oracle Forms, but the use of a List of Values (LOV) on your LOCATION table might do the trick for you. If you create a dynamic LOV based on your LOCATIONS table, it can then be referenced by the LOC_ID item on the Master-Detail page, to display the Location Name. You could try doing the following:
1. Create a new dynamic LOV, LOCATIONS, using a query similar to the following:
select Name d, ID r
from LOCATION
order by 1
2. Edit the "Create" button on the Master report page, and in the "Optional URL Redirect" section set "Request" to CREATE. Click Apply Changes, to save the setting.
3. Edit the LOC_ID item on your Master-Detail page, and set the following:
* in the "Name" region change the "Display As" setting to Select List
* in the "Label" region change the Label to Location Name.
* in the "List of Values" region set the "Named LOV" to LOCATIONS
* in the "Read Only" section, set the condition to Request != Expression 1, and set Expression 1 to CREATE.
Click Apply Changes to save the settings.
When you run the pages now, the Location Name field will appear as Read-Only when editing a selected Master row. The item will appear as a Select List when the user clicks "Create" on the Master page, to create a new Master row.
I hope this helps.
Regards,
Hilary

Master populating detail automatically

hi guys, I currently have a master detail relationship, what i would like is for when a value is selected from the master is for the detail to automatically be populated. Anyone any idea how this could be done.
Thanks.

If you have created a "Relationship" object between the Master block and the Detail block, this should happen automatically (see the Block => Relationship node in the Object Navigator). If you haven't created a Relationship; create one and list just the join criteria in the "Join Condition" - don't include the "WHE RE" key word as this is implicit.
If your master/detail blocks don't support the creation of a Relationship object, then you have to manually code the relationship functionality. This can be accomplished using the Master Block When-New-Record-Instance (WNRI) trigger and setting the DEFAULT_WHER E clause on the Detail block and executing a query on the detail block. For example:
/* Sample Master Block WNRI trigger */
/* This example uses the HR schema Demo Tables */
/* and will simulate the relationship between the */
/* DEPARTMENTS table and the EMPLOYEES table. */
DECLARE
   v_temp_clause       VARCHAR2(500);
   /* the v_def_clause is used with Forms 6i */
   v_def_clause          VARCHAR2(500) := Get_Block_Property('EMPLOYEES',DEFAULT_WHER E);
BEGIN
   v_temp_clause := 'department_id = '||:DEPARTMENTS.DEPARTMENT_ID;
   /* Use the ONETIME_WHER E Property for Forms 9i+ */
   Set_Block_Property('EMPLOYEES',ONETIME_WHER E, v_temp_clause);
   /* If Forms 6i */
   Set_Block_Property('EMPLOYEES',DEFAULT_W HERE, v_temp_clause);
   Go_Block('EMPLOYEES');
   Execute_Query;
   /* If Forms 6i, restore the original Default Whe re clause */
   Set_Block_Property('EMPLOYEES', DEFAULT_W HERE, v_def_clause);
   /* return to the Departments block */
   Go_Block('DEPARTMENTS');
END;In the future, please include your Forms version at a minimum. Preferably, include any other software versions (JRE, Browser, etc) as these may help us troubleshoot your question. ;-)
Hope this helps,

If someone's response is helpful or correct, please mark it accordingly.

Master-details query to XML file?

Hi:
I'm new in XML and Oracle. I want to create XML file from two tables (master-details).
I made a small serach and tried some examples:
Say we have these tables:
CREATE TABLE "TEST_XML"
(     "ID" NUMBER,
     "NAME" VARCHAR2(15),
     "AMOUNT" NUMBER,
     CONSTRAINT "TEST_XML_PK" PRIMARY KEY ("ID") ENABLE
CREATE TABLE "TEST_XML2"
(     "ID2" NUMBER,
     "NAME2" VARCHAR2(20),
     "AMOUNT2" NUMBER
ALTER TABLE "TEST_XML2" ADD CONSTRAINT "TEST_XML2_FK" FOREIGN KEY ("ID2")
     REFERENCES "TEST_XML" ("ID") ENABLE
INSERT INTO TEST_XML VALUES (1,'A',50);
INSERT INTO TEST_XML VALUES (2,'B',30);
INSERT INTO TEST_XML VALUES (3,'C',70);
INSERT INTO TEST_XML2 VALUES (1,'AA',10);
INSERT INTO TEST_XML2 VALUES (1,'AB',20);
INSERT INTO TEST_XML2 VALUES (1,'AC',20);
INSERT INTO TEST_XML2 VALUES (2,'BA',10);
INSERT INTO TEST_XML2 VALUES (2,'BB',20);
INSERT INTO TEST_XML2 VALUES (3,'CA',20);
INSERT INTO TEST_XML2 VALUES (3,'CB',40);
INSERT INTO TEST_XML2 VALUES (3,'CC',10);
I want a query to create XML file contains data from TEST_XML table and for each row the related data from TEST_XML2 table.
I did some tries (working in iSQL*PLUS):
SET SERVEROUTPUT ON
DECLARE
v_ctx DBMS_XMLGEN.ctxType;
v_file Utl_File.File_Type;
v_xml CLOB;
v_more BOOLEAN := TRUE;
BEGIN
-- Create XML document from query.
v_ctx := DBMS_XMLGEN.newContext('select id,name,amount,cursor (select id2,name2,amount2 from test_xml2 t2 where t2.id2=t1.id) val from test_xml t1');
DBMS_XMLGEN.setMaxRows(v_ctx, 10);
DBMS_XMLGEN.setRowsetTag(v_ctx, 'CLAIM');
-- Output XML document to file.
v_file := Utl_File.FOpen('TEST_DIR', 'test1.xml', 'w');
WHILE v_more
LOOP
v_xml := DBMS_XMLGEN.GetXML(v_ctx,0);
EXIT WHEN dbms_xmlgen.getNumRowsProcessed(v_ctx) =0;
Utl_File.Put(v_file,v_xml);
END LOOP;
Utl_File.FClose(v_file);
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE(SUBSTR(SQLERRM,1,255));
Utl_File.FClose(v_file);
END;
But hte output wasn't as I wanted:
<CLAIM>
<ROW>
<ID>1</ID>
<NAME>A</NAME>
<AMOUNT>50</AMOUNT>
<VAL>
<VAL_ROW>
<ID2>1</ID2>
<NAME2>AA</NAME2>
<AMOUNT2>10</AMOUNT2>
</VAL_ROW>
<VAL_ROW>
<ID2>1</ID2>
<NAME2>AB</NAME2>
<AMOUNT2>20</AMOUNT2>
</VAL_ROW>
<VAL_ROW>
<ID2>1</ID2>
<NAME2>AC</NAME2>
<AMOUNT2>20</AMOUNT2>
</VAL_ROW>
</VAL>
</ROW>
<ROW>

<VAL_ROW>
<ID2>2</ID2>
<NAME2>BB</NAME2>
<AMOUNT2>20</AMOUNT2>
</VAL_ROW>
</VAL>
</ROW>
</CLAIM>
Notice that for each details (from TEST_XML2) there is <VAL> tag which I don't need beside i want a query which is applicable on all environments.
May anyone help me please......

Saad

The following looks like it produces your desired output. I used the WITH to simulate your two tables so I didn't have to CREATE them. This runs on 10.2.0.1. I'm not sure what bugs you are referring to as SQL/XML is stable in 10g that I have seen. I'm sure some bugs exist somewhere in it, just not with this usage. Just start with the SELECT statement to run on your system.
WITH test_xml AS
(SELECT 1 ID, 'A' name, 50 amount FROM DUAL UNION ALL
SELECT 2, 'B', 30 FROM DUAL UNION ALL
SELECT 3, 'C', 70 FROM DUAL),
test_xml2 AS
(SELECT 1 ID2, 'AA' name2, 10 amount2 FROM DUAL UNION ALL
SELECT 1, 'AB', 20 FROM DUAL UNION ALL
SELECT 1, 'AC', 20 FROM DUAL UNION ALL
SELECT 2, 'BA', 10 FROM DUAL UNION ALL
SELECT 2, 'BB', 20 FROM DUAL UNION ALL
SELECT 2, 'BC', 20 FROM DUAL UNION ALL
SELECT 3, 'CA', 20 FROM DUAL UNION ALL
SELECT 3, 'CB', 40 FROM DUAL UNION ALL
SELECT 3, 'CC', 10 FROM DUAL)
SELECT XMLElement("CLAIM",
         XMLAgg(
           XMLElement("ROW",
             XMLForest(id "ID",
                       name "NAME",
                       amount "AMOUNT"),
             (SELECT XMLAgg(XMLElement("VAL_ROW",
                             XMLForest(id2 "ID2",
                                       name2 "NAME2",
                                       amount2 "AMOUNT2")))
                      FROM test_xml2 t2
                     WHERE t2.id2=t1.id)
FROM test_xml t1This solution works in any environment where you can issue a SQL statement from, be it SQL*Plus, PL/SQL, Java, etc.

Post query trigger problem in master detail oracle forms

Hello experts,
I am new in oracle forms n using Fission middleware 10g with oracle forms 11g at windows 7 platform.
I have made a master detail form using a tab canvas.There is a database column STUDENTID and it is in my student tab with a TBL_STUDENTENTRY data block.Now I Have an another tab named previous_education with TBL_STUDENT_PREVIOU_EDU datablock here there is also a database column STUDENTID and corresponding field in my previous_education TAB under TBL_STUDENT_PREVIOU_EDU datablock.Now i want to add a display item to show student name corresponding to STUDENTID.For this I have tried to make a select query in TBL_STUDENT_PREVIOU_EDU data block POPST_QUERY TRIGGER.
begin
select STUDENTNAME into :TBL_STUDENT_PREVIOU_EDU.STD_NM from TBL_STUDENTENTRY where STUDENTID=:TBL_STUDENTENTRY.STUDENTID;
end;
But, This trigger is not fired at runtime,Please suggest me what is going wrong and give me the solution.
Thank You

Auto Query in Master Detail Form using dynamic page doesn't work

I created a Master-Detail form, and implement AutoQuery using a dynamic page
with the following code :

end if;

It works fine when we access the first time to the page, but if i press the
save button after inserting or updating a detail record, the header record is
lost. How can i avoid this situation ?

'***id***', id
) Edit,
id,

Query button in Master/Detail form

Hello All,
I created a Master / detail form...looks good for a blind query and for a specific column value...
The problem is When the user selects query button ,how do I show records that the logged in user has created.
Am already storing username in the table when the user inserts new record.
Appreciate if you could send code ..if that's the choice to fix my issue..
Thanks in advance
Babu

Hi,
Write the following code in 'Query' event of the 'Query' button in your form ..
p_session.set_shadow_value(p_block_name => 'DEFAULT',
p_attribute_name => 'A_USER_ID',
p_value => portal30.wwctx_api.get_user,
p_language => PORTAL30.wwctx_api.get_nls_language);
doQuery;
Replace 'A_USER_ID' with name of your user id field . I hope you have selected this field in your form and if not select this field & hide it in the form to make this code to work.

Query mode of Master Detail Form

I have a master-detail form.
I'm passing parameters to that form to autoquery data.
Everything works fine but "Next" button in a detail block.
I'm getting:
An unexpected error occurred: ORA-06502: PL/SQL: numeric or value error: NULL
index table key value (WWV-16016).
After autoquery LASTIN_SET variable of DEFAULT block is set "5" (number of rows in detail block).
When I click on "Next" button LASTIN_SET variable is set to "0" instead of "5" and that causes a problem.
So, somehow LASTIN_SET is not preserved between clicks.

What I'm missing here.
Aantoliy.

Say, I click on Update Push button. This will invoke a LOV that will occurs 5 times and then display the header and detail record.
Even if, I am able to get the records in the canvas, I am not able to update the records of the master. The record_status is in INSERT mode of the header block. Interestingly, if i click 2nd time on update button and then get the records after executing LOV, the query enters the query mode and I am able to update the records then.
Please suggest how to overcome the problem on a sigle click on UPDATE button.

Af:query for master detail

Hi Experts,
Can we have an af:query to show master detail data ?
What we generally have is af:query showing records of 1 table. What i want is for the records that get populated from af:query in the master table, i want to show the records in the detail table of the row selected
any idea ?
thnks

Thank you NewBee. It worked and am able to get the detail information from the master table. I am struggling with another implementation. I have 3 radio buttons in the global template which I am referencing in all my pages.
The template has 3 radio buttons. Contacts, Plans and Users. The three queries are completely different from one another.
On click of Contacts, I should display the respective af:query for Contacts, Plans and Users without displaying the resultant table. This query panel will be global to all the pages.
I have tried setting it as follows:
<af:panelGroupLayout layout="vertical"
id="pt_pgl3"
rendered="#{baseBean.searchContactsSelected == 'true'}"
visible="#{baseBean.searchContactsSelected == 'true'}">
<af:query id="qryId1" headerText="Search" disclosed="true"
value="#{bindings.GloablSearchByContactsVOCriteriaQuery.queryDescriptor}"
model="#{bindings.GloablSearchByContactsVOCriteriaQuery.queryModel}"
queryListener="#{bindings.GloablSearchByContactsVOCriteriaQuery.processQuery}"
queryOperationListener="#{bindings.GloablSearchByContactsVOCriteriaQuery.processQueryOperation}"
resultComponentId="::contactSearch:md1"/>
<f:subview id="contactSearch">
<jsp:include page="/contactsSearchResults.jspx"/>
</f:subview>
<af:panelGroupLayout>
I have tried various implementations to the best of my knowledge but its not rendering. Is it possible to navigate to a different jspx on click of Search button of af:query. This will give me an opportunity to display different pages based on the Search action and keeping the search on a global level.
Hope I was clear in explaining the issue
Thanks!

Master Detail Report using Report Query

I am using APEX Report Query component to try and create a mater/detail report with BI plug-in. The Report Queries doesn't give you mush flexibility as each query is independent of the other. I'm trying to see if I need to create 2 queries or 1 AND what option would let me create a master detail report like so in BI Desktop:
Employee: Bob ID:100 Dept: HR
Jobs
Job 1
Job 2
Job 3
Employee: Tom ID:200 Dept: ACCt
Jobs
Job 1
Job 2
Job 3
Option1.
I could combine the Employee Job info with the Employee info, but that would report the Employee info for every Employee Job. I didn't think that was good.
<Rowset1_Row>
<EMPID>
<NAME>
<DEPT>
<JOB>
</Rowset1_Row>
Option 2.
I could create 2 queries. The 1st getting all of the Empoyee info. The 2nd getting all of the Employee jobs.
<Rowset1_Row>
<EMPID>
<NAME>
<DEPT>
<JOB>
</Rowset1_Row>
<Rowset2_Row>
<EMPID>
<JOB>
</Rowset2_Row>
<Rowset2_Row>
<EMPID>
<JOB>
</Rowset2_Row>
Any advice?

Restricting Query in master detail situation

I got two tables and three forms 1)master-detail 2)a selection form based on detial table.
When we enter data in master form i.e deptno want to open a selection form with restricting query only to those records that is entered in master from.
I want to know how to restrict data in selection form.Bit confusing,
Thank You,
Zubyr

add a parameter to your detail form, and set the default-where property of your block.
you can reference parameters directly in the where clause of the block:
deptno = :parameter.deptno
call your detailform from the masterform with a paramlist
declare
xParamlist paramlist;
begin
xParamlist := Get_Parameter_List('PARAMLIST');
IF (id_null (xParamList)) THEN
xParamList := create_parameter_list ('PARAMLIST');
ELSE
destroy_parameter_list (xParamList);
xParamList := create_parameter_list ('PARAMLIST');
END IF;
Add_Parameter(xParamlist,'EMPNO',TEXT_PARAMETER, :master.deptno);
call_form('detailform',NO_HIDE,NO_REPLACE,NO_QUERY_ONLY,xParamList);
end;
