Creating Views in 10GR2 Mapping

When using a mapping to populate a view, the query is not populated into the view like in 9.2. Is this a feature or am I doing something wrong? I created the view as unbounded object, then connected it to the mapping, bound the view and sync out. This use to work in 9.2 but I can't get it to work in 10GR2.

Hi,
This is a bug as far as I know and will be fixed (hopefully). Borkur, this feature is an enormous help if you have complex views. It enables you to define them on the metadata layer like a mapping.
Good News: there is a workaround
1. Generate the mapping in the mapping editor
2. Select the INOUTGRP1 of the view operator
3. Set Generation Style: Intermediate
4. Set Operating Mode: SET_BASED
5. Set Aspect: Incoming
6. Copy the generated output 1:1 into the Query Tab of the view
Thats's all

How can i create a more detailed map in aperture?

How can i create a more detaled map in Aperture- Book?

There are no templates for more detailed maps in Aperture.
You might consider to add more detailed maps as photos to the photo boxes in the book. I sometimes simply take a screenshot of the map in "Places" view to get a more detailed map with the pins marking the places.

Creating view if you got SQL right?

Hi,
I've a table called branch with following columns:
branch id, branch name, location, company
Now I've to get following display: number of branchs location wise per company... in SQL I'd write following query:
select count(branch_id), location from branch where company_id = 'oracle' group by location;
Now I am trying similar thing in ADF view, I've two attributes in my view:
location - i select mapped to column or sql - and write following in expression - select location from branch where company_id = 'oracle' group by location
number of branches - i select mapped to column or sql - and write following in expression - select count(branch_id) from branch where company_id = 'oracle' group by location
However it gives error. Can anyone help how to create view if I've got my SQL right?
Thanks.

Just make a Expert mode VO (New View Object _>"Red_only Access through SQL Query") and put the following SQL -
select company_id,count(branch_id), location,branch_id from branch where company_id = 'oracle' group by location;And keep clicking next on the wizard ... your VO should get created with 4 fields ... CompanyId,Location,BranchId,CountBranchId (which you can rename if you want).
Run it in the AM you should see correct results ... You dont need to put specific SQLs in the attributes like what you are doing.

How can I create a circular site-map?

I want to create a circular structure in my website ( page a--> page b--> page c---> page d --- and then again page a)
How is this possible in muse to create a link between d and a in de site-map??
thanks a lot!

hej!
the idea is a bit like this website:
http://www.comme-des-garcons.com
go from one page to another…without other options. I want to create a

Problem with embeding the same view in dynamically created view container

Hello Experts,
              I am getiing a dump when i try to embed the same view inside the dynamically created view container of
dynamically created tabs of a tabstrip
The requirement go like this, i have 2 views in which i have have to embed the 2nd view to view1 where i have an empty
tabstrip without tabs. During runtime i create tabs as well as view containers accordingly and then try to embed view2 in tabs.
I have put the below mentioned code in HANDLEIN,
DATA: lref_vcntlr TYPE REF TO if_wd_view_controller,
        lref_comp    TYPE REF TO if_wd_component_usage,
        lv_embed_pos TYPE string.
lref_vcntlr = wd_this->wd_get_api( ).
lv_embed_pos = 'FILE_PERS_EDIT/VC_GENERAL'.
TRY.
      CALL METHOD lref_vcntlr->do_dynamic_navigation
        EXPORTING
          source_window_name        = 'FILE_PERSISTENCE_WND'          " Window
          source_vusage_name        = 'FILE_PERS_EDIT_USAGE_1'       " Source View usage
          source_plug_name          = 'TO_EDIT_LAYOUT'                       " Outbound plug
          target_view_name          = 'PERS_EDIT_LAYOUT'                  " Second view to be embedded
          target_plug_name          = 'IN'                                                  " Second view inboun plug
          target_embedding_position = lv_embed_pos
        RECEIVING
          component_usage           = lref_comp.
    CATCH cx_wd_runtime_repository .
ENDTRY.
wd_this->fire_to_edit_layout_plg( ).
This works fine for the first time.
However onaction tab select i change the embeding position( 'FILE_PERS_EDIT/view container name of different tab') of the view2 an try to embed view2 in a different tab.
At this point i get a dump stating View2 already present in the window 'FILE_PERSISTENCE_WND' of component.
I think, the view2 embediing has to be removed before i add the view2 in a different tab
Kindly let me know how to remove view2 embedding from tab1 before i add a view2 to a different tab or is there any other
means to handle this problem?
Thanks & Best Regards,
Srini.

Hello Srini,
I found a solution to your problem, because I had a similar task.
In WDDOINIT I changed the method do_dynamic_navigation to if_wd_navigation_services_new~prepare_dynamic_navigation:
DATA:
    l_view_controller_api TYPE REF TO if_wd_view_controller.
l_view_controller_api = wd_this->wd_get_api( ).
TRY.
      CALL METHOD l_view_controller_api->if_wd_navigation_services_new~prepare_dynamic_navigation
        EXPORTING
          source_window_name        = 'WDW_MAIN'
          source_vusage_name        = 'VW_SUB_USAGE_1'
          source_plug_name          = 'TO_VW_CONTENT'
          target_component_name     = 'ZTEST_DYNAMIC'
          target_view_name          = 'VW_CONTENT'
          target_plug_name          = 'DEFAULT'
          target_embedding_position = 'VW_MAIN/VC_TAB.VW_SUB/TAB1_VC'
        RECEIVING
          repository_handle         = wd_this->g_rep_handle.
    CATCH cx_wd_runtime_repository .
ENDTRY.
wd_this->fire_to_vw_content_plg( param1 = 'TAB1' ).
In the action I first deleted the navigation targets, then navigated to the empty-view and last I called my target view:
DATA:
    lv_position           TYPE string,
    l_view_controller_api TYPE REF TO if_wd_view_controller,
    lr_view_usage         TYPE REF TO if_wd_rr_view_usage,
    lr_view_***_t         TYPE wdrr_vca_objects,
    lr_view_***           LIKE LINE OF lr_view_***_t.
l_view_controller_api = wd_this->wd_get_api( ).
lr_view_usage = wd_this->g_view->get_view_usage( ).
lr_view_usage->delete_all_navigation_targets( plug_name = 'TO_VW_CONTENT' ).
CLEAR lv_position.
CONCATENATE 'VW_MAIN/VC_TAB.VW_SUB/' old_tab '_VC' INTO lv_position.
TRY.
      l_view_controller_api->if_wd_navigation_services_new~do_dynamic_navigation(
      source_window_name = 'WDW_MAIN'
      source_vusage_name = 'VW_SUB_USAGE_1'
      source_plug_name   = 'TO_EMPTYVIEW'
      target_component_name = 'ZTEST_DYNAMIC'
      target_view_name   = 'EMPTYVIEW'
      target_plug_name   = 'DEFAULT'
      target_embedding_position = lv_position ).
    CATCH cx_wd_runtime_repository.
ENDTRY.
CLEAR lv_position.
CONCATENATE 'VW_MAIN/VC_TAB.VW_SUB/' tab '_VC' INTO lv_position.
TRY.
      wd_this->g_rep_handle = l_view_controller_api->if_wd_navigation_services_new~prepare_dynamic_navigation(
        source_window_name = 'WDW_MAIN'
        source_vusage_name = 'VW_SUB_USAGE_1'
        source_plug_name   = 'TO_VW_CONTENT'
        target_component_name = 'ZTEST_DYNAMIC'
        target_view_name   = 'VW_CONTENT'
        target_plug_name   = 'DEFAULT'
        target_embedding_position = lv_position ).
    CATCH cx_wd_runtime_repository.
ENDTRY.
wd_this->fire_to_vw_content_plg( param1 = tab ).
Ann.: I my example, I had 3 views: VW_MAIN which embedds VW_SUB. VW_SUB has the tabs in it and VW_SUB embedds VW_CONTENT.

Create view and alter Session gets 0RA-01031

I can't create a view after using ALTER SESSION set current_schema without using an explicit schema. I get ORA-01031. Is this a known bug? Here are the details:
1. Log on as SYSTEM
2. ALTER SESSION set current_schema=FRED;
3. CREATE VIEW vFoo as select * from Foo; -- ORA-01031: insufficient privileges
4. CREATE VIEW FRED.vFoo as select * from Foo; -- this works!
I've read where some privileges need to be granted directly. In fact, if Fred grants select privilege on Foo to SYSTEM, the statement in #3 above works. However, something doesn't seem right because why does #4 succeed without the GRANT?
In case you're wondering why I don't just use #4 above, which does work, it's because I've got a script that will be run by customers to create tables, views, etc. in an arbitrary schema and the schema is associated with a user with limited permissions. Hence, the use of the ALTER SESSION.

See, You looged as SYSTEM (Scheme = SYSTEM)
Now you alter your session to another schema FRED.
Now if you want to access SCHEMA of FRED, You need to connect first.
SQL > connect user/password@host
Then
SQL > CREATE VIEW vFoo as select * from Foo;
View created.

In generic extration how to create view

HI
In se11 i try to create view using two table vbap and vbak .
vbak mandt vbap mandt
vbak vbeln vbap vbeln for join condion
and also i fill view field tab but the view is no cretated. It give error field name MANDT is not unique. please anyoone clar the error.
By
Rajan

Hi Rajan,
You cannot use one field twice in a View.
If you need the Field "MANDT" from both the tables, change the description as MANDT_VBAK & MANDT_VDAT in View Field column & select it from the respective tables in "Table column".
Hope it helps!

How to CREATE VIEW to merge two tables each of which has CLOB-typed column

I failed in creating a view to merge two tables that have CLOB-type column each.
The details are:
Database: Oracle 9i (9.2.0)
Two tables "test" and "test_bak", each of which has the following structure:
ID Number(10, 0)
DUMMY VARCHAR2(20)
DUMMYCLOB CLOB
The following operation fails:
create view dummyview (id, dummy, dummyclob) as
select id, dummy, dummyclob from test
union
select id, dummy, dummyclob from test_bak;
I was announced:
select test.id, test.dummy, test.dummyclob
ERROR in line 2:
ORA-00932: inconsistent data type: required - , but CLOB presented.
But if creating views from only ONE table with CLOB-type columns, or from two tables WITHOUT CLOB-typed columns, the creation will succeed. The following 1) and 2) will succeed, both:
1) one table, with CLOB-typed column
create view dummyview (id, dummy, dummyclob) as
select id, dummy, dummyclob from test;
2) two tables, without CLOB-typed columns
create view dummyview (id, dummy) as
select id, dummy from test
union
select id, dummy from test_bak;
I want to merge the two tables all, with complete columns, how to write the CREATE VIEW SQL statement?
many thanks in advance

Dong Wenyu,
No.
But you could do this:
SELECT source.*, nvl (tab1.clob_column, tab2.clob_column)
FROM your_table1 tab1, your_table2 tab2, (
SELECT primary_key, ...
FROM your_table1
UNION
SELECT primary_key, ...
FROM your_table2
) source
WHERE source.primary_key = tab1.id (+)
AND source.primary_key = tab2.id (+)
In other words, do the set operation (UNION (ALL)/INTERSECT/MINUS) on just the PK columns before pulling in the LOB columns.

Error while creating view

Hello,
I am trying to create view which is based on multiple source tables and I am receiving following error
Internal error: An expression services limit has been reached. Please look for potentially complex expressions in your query, and try to simplify them.
Can anyone know how to resolve this.
Thanks,

Hello,
The problem could be a SAPGUI related problem... Whats the current sapgui patch level ? Does it work when you try on another wokstation with the same user ?
Could you please use SAPGUI 720 and update your patch level to 7 ? Then check the behaviour again.

Non-sense error message trying to create view

Greetings All,
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production on Windows 2008R2
I am getting an error while trying to create a view. The error makes no sense in that no attempt to change a user name or password as the error message being produced suggests.
I can execute the entire select statement fine, I get results back.
If I comment out the line indicated as being in error, the problem moves to the line prior to the one commented out. The 4 lines prior to the line indicated by the error message are similar. The error is occurring on the last of the 5 similar lines of code.
If I move all 5 lines further up in the code the error moves accordingly.
The function validate_number (near where the error is identified) under certain conditions will issue a execute immediate 'alter session set nls_numeric_characters = ''.,''';
The column number identified in the error message is 2 spaces prior to the validate_number function call.
Below is the syntax for the creation of the view, the error message is at the bottom.
The numbers to the far left indicate the line number. I put 2 blank lines before and after the line of code identified by the error message.
The error points to the 2-spaces in front of the VALIDATE_NUMBER function call on line 350. just before the sql code ==> validate_number(Spend_Qty,'')),0) <==
Thanks for your time,
Bob

SQL Error: ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges"
*Cause:    An attempt was made to change the current username or password
without the appropriate privilege. This error also occurs if
attempting to install a database without the necessary operating
system privileges.
When Trusted Oracle is configure in DBMS MAC, this error may occur
if the user was granted the necessary privilege at a higher label
than the current login.
*Action:   Ask the database administrator to perform the operation or grant
the required privileges.
For Trusted Oracle users getting this error although granted the
the appropriate privilege at a higher label, ask the database
administrator to regrant the privilege at the appropriate label.

Checking for privileges was the first thing I did.
User has create view and create any view.
Also has alter session privilege which is needed within the validate_number function (see below).
I was able to create the view you suggested.
I believe there is a privilege problem, just cant figure which.
create or replace function validate_number(p_number      in varchar2,
                                           p_format_mask in varchar2)
return number
AUTHID CURRENT_USER is
v_number number;
v_mask   varchar2(100) := '999999999999999999999.00000000000000000000';
cursor get_number_masks is
select mask,upper(is_i18n) is_i18n from cm_master.format_mask
where type = 'NUMBER' order by sequence, is_i18n;
begin
if p_format_mask is not null then
    begin
      return to_number(p_number, p_format_mask);
    exception
      when others then null;
    end;
end if;
for a in get_number_masks
loop
    if a.is_i18n = 'Y' then
      -- We are applying an international number format mask
      begin
        -- Attempt #1
        -- Set the decimal to a ',' and the group separator to a '.'
        execute immediate 'alter session set nls_numeric_characters = '',.''';
        v_number := to_number(ltrim(rtrim(to_char(to_number(p_number, a.mask),v_mask))),v_mask);
        execute immediate 'alter session set nls_numeric_characters = ''.,''';
        return v_number;

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

Hi, Karthick,

... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.

Creating View for a table with parent child relation in table

I need help creating a view. It is on a base table which is a metadata table.It is usinf parent child relationship. There are four types of objects, Job, Workflow, Dataflow and ABAP dataflow. Job would be the root parent everytime. I have saved all the jobs
of the project in another table TABLE_JOB with column name JOB_NAME. Query should iteratively start from the job and search all the child nodes and then display all child with the job name. Attached are the images of base table data and expected view data
and also the excel sheet with data.Picture 1 is the sample data in base table. Picture 2 is data in the view.
Base Table

I implemented the same in oracle using CONNECT_BY_ROOT and START WITH.

I think what you need is recursive CTE
Consider your table below
create table basetable
(PARENT_OBJ varchar(10),
PAREBT_OBJ_TYPE varchar(10),
DESCEN_OBJ varchar(10),DESCEN_OBJ_TYPE varchar(10))
INSERT basetable(PARENT_OBJ,PAREBT_OBJ_TYPE,DESCEN_OBJ,DESCEN_OBJ_TYPE)
VALUES('JOB_A','JOB','WF_1','WORKFLOW'),
('JOB_A','JOB','DF_1','DATAFLOW'),
('WF_1','WORKFLOW','DF_2','DATAFLOW'),
('DF_1','DATAFLOW','ADF_1','ADF'),
('JOB_B','JOB','WF_2','WORKFLOW'),
('JOB_B','JOB','WF_3','WORKFLOW'),
('WF_2','WORKFLOW','DF_3','DATAFLOW'),
('WF_3','WORKFLOW','DF_4','DATAFLOW'),
('DF_4','DATAFLOW','ADF_2','ADF')
ie first create a UDF like below to get hierarchy recursively
CREATE FUNCTION GetHierarchy
@Object varchar(10)
RETURNS @RESULTS table
PARENT_OBJ varchar(10),
DESCEN_OBJ varchar(10),
DESCEN_OBJ_TYPE varchar(10)
AS
BEGIN
;With CTE
AS
SELECT PARENT_OBJ,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM basetable
WHERE PARENT_OBJ = @Object
UNION ALL
SELECT b.PARENT_OBJ,b.DESCEN_OBJ,b.DESCEN_OBJ_TYPE
FROM CTE c
JOIN basetable b
ON b.PARENT_OBJ = c.DESCEN_OBJ
INSERT @RESULTS
SELECT @Object,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM CTE
OPTION (MAXRECURSION 0)
RETURN
END
Then you can invoke it as below
SELECT * FROM dbo.GetHierarchy('JOB_A')
Now you need to use this for every parent obj (start obj) in view
for that create view as below
CREATE VIEW vw_Table
AS
SELECT f.*
FROM (SELECT DISTINCT PARENT_OBJ FROM basetable r
WHERE NOT EXISTS (SELECT 1
FROM basetable WHERE DESCEN_OBJ = r.PARENT_OBJ)
)b
CROSS APPLY dbo.GetHierarchy(b.PARENT_OBJ) f
GO
This will make sure it will give full hieraracy for each start object
Now just call view as below and see the output
SELECT * FROM vw_table
Output
PARENT_OBJ DESCEN_OBJ DESCEN_OBJ_TYPE
JOB_A WF_1 WORKFLOW
JOB_A DF_1 DATAFLOW
JOB_A ADF_1 ADF
JOB_A DF_2 DATAFLOW
JOB_B WF_2 WORKFLOW
JOB_B WF_3 WORKFLOW
JOB_B DF_4 DATAFLOW
JOB_B ADF_2 ADF
JOB_B DF_3 DATAFLOW

Create view link programatically

Hi all,
I am working on this weird requirement.
Basically, I have to create a detail table on a search resullt table. The search result is seeded search, for Item Advance search in Oracle PIM module which is not based upon a VO. The search result table is dynamically built at run time in the EgoItemSearchHelper class and that's where they build the search result VO (EgoItemSearchResultsVO).
Now, I need to access this VO in the controller class, and create a view link programatically between details table VO and this VO. The problem is since I do not have Impl class for the EgoItemSearchResultsVO, how do I accees the column that is the key attribute. Second I do not know how to create view link between the two VOs programatically.
Please help it's urgent.
Thanks

Pratap, My problem is the seeded VO is in seeded AM and my details VO will be in my custom AM, I don't know if we can have a view link between View objects that are in different AMs.
To bypass that problem, I tried to create a VO in the seeded AM programatically and then created a view link. Now since the AM is seeded, and I am adding my details VO to this AM programatically, I thought of creating a table also programatically on the detais VO.
In the end it does not work, I end up getting a show button on the main table, but when I click I get an error (Cannot find <null> attribute in the EOGITEMSEARCHRESULTVO) which is the seeded VO class. Unfortunately there is no boolean variable on the dynamic seeded VO, so don't know what to put in oatablebean.setDetailViewAttributeName("") method;
Any clues on this, appreciate all responses from the forum gurus.
ViewObject voEmp = oaapplicationmodule.createViewObject("MyEmp", "xxuss.oracle.apps.ego.item.eu.server.DetailsOrderLinesVO");
ViewObject voEmp = am.createViewObject("MyEmp", "xxuss.oracle.apps.ego.item.eu.server.DetailsOrderLinesVO");
AttributeDef[] prjLinkAttrs = new AttributeDef[]{oaapplicationmodule.findViewObject("EgoItemSearchResultsVO").findAttributeDef("INVENTORY_ITEM_ID_B")};
System.out.println("definition for attr = "+ prjLinkAttrs[0]);
AttributeDef[] taskLinkAttrs = new AttributeDef[]{voEmp.findAttributeDef("InvId") };
ViewLink vl = am.createViewLinkBetweenViewObjects("MyLink3",
"DetailInv", // accessor name--more on this below
am.findViewObject("EgoItemSearchResultsVO"), // master
prjLinkAttrs, // department attributes
voEmp, // detail
taskLinkAttrs, // employee attributes
null); // assoc clause
System.out.println("view link =" + vl.getName());
OATableBean tb = (OATableBean)createWebBean(oapagecontext,TABLE_BEAN,null,"table");
tb.setViewUsageName("MyEmp");
OAMessageStyledTextBean beans = (OAMessageStyledTextBean)createWebBean(oapagecontext,MESSAGE_STYLED_TEXT_BEAN,OAWebBeanConstants.VARCHAR2_DATATYPE,"number");
beans.setPrompt("column1");
beans.setViewUsageName("MyEmp");
beans.setViewAttributeName("InvId");
tb.addIndexedChild(beans);
oatablebean.setDetail((OAWebBean)tb);
oatablebean.setDetailViewAttributeName("SelectFlag"); // I just tried this, SelectFlag is not a boolean attribute though, is there a way to create a boolean attribute programatically for seeded VO EGOITEMSEARCHRESULTVO and set it here, will it help
oatablebean.setAllDetailsEnabled(true);

Best practice to create views

Hi,
I've a question about best practice to develop a large application with many complex views.
Typically at each time only one views is displayed. User can go from a view to another using a menu bar.
Every view is build with fxml, so my question is about how to create views and how switch from one to another.
Actually I load fxml every time the view is required:
FXMLLoader loader = new FXMLLoader();
InputStream in = MyController.class.getResourceAsStream("MyView.fxml");
loader.setBuilderFactory(new JavaFXBuilderFactory());
loader.setLocation(OptixController.class.getResource("MyView.fxml"));
BorderPane page;
try {
     page = (BorderPane) loader.load(in);
     } finally {
          if (in != null) {
               in.close();
// appController = loader.getController();
Scene scene = new Scene(page, MINIMUM_WINDOW_WIDTH, MINIMUM_WINDOW_HEIGHT);
scene.getStylesheets().add("it/myapp/Mycss.css");
stage.setScene(scene);
stage.sizeToScene();
stage.setScene(scene);
stage.sizeToScene();
stage.centerOnScreen();
stage.show();My questions:
1- is a good practice reload every time the fxml to design the view?
2- is a good practice create every time a new Scene or to have an unique scene in the app and every time clear all elements in it and set the new view?
3- the views should be keep in memory to avoid performace issue or it is a mistake? I think that every time a view should be destroy in order to free memory.
Thanks very much

3- the views should be keep in memory to avoid performace issue or it is a mistake? I think that every time a view should be destroy in order to free memory.
In choosing between 1 and 3 above, I think either is fine. Loading the FXML on demand every time will be slightly slower, but assuming you are not doing something unusual such as loading over a network connection it won't be noticeable to the user. Loading all views at startup and keeping them in memory uses more memory, but again, it's unlikely to be an issue. I would choose whichever is easier to code (probably loading on demand).
In choosing between reusing a Scene or creating a new one each time, I would reuse the Scene. "Clearing all elements in it" only needs you to call scene.setRoot(...) and pass in the new view. Since the Scene has a mutable root property, you may as well make use of it and save the (small) overhead of instantiating a new Scene each time. You might consider exposing a currentView property somewhere (say, in your main controller, or model if you have a separate model class) and binding the Scene's root property to it. Something like:
public class MainController {
private final ObjectProperty<Parent> currentView ;
public MainController() {
    currentView = new SimpleObjectProperty<Parent>(this, "currentView");
public void initialize() {
    currentView.set(loadView("StartView.fxml"));
public ObjectProperty<Parent> currentViewProperty() {
    return currentView ;
// event handler to load View1:
@FXML
private void loadView1() {
    currentView.set(loadView("View1.fxml"));
// similarly for other views...
private Parent loadView(String fxmlFile) {
    try {
     Parent view = FXMLLoader.load(getClass().getResource(fxmlFile));
     return view ;
    } catch (...) { ... }
}Then your application can do this:
@Override
public void start(Stage primaryStage) {
   Scene scene = new Scene();
   FXMLLoader loader = new FXMLLoader(getClass().getResource("Main.fxml"));
   MainController controller = (MainController) loader.getController();
   scene.rootProperty().bind(controller.currentViewProperty());
   // set scene in stage, etc...
}This means your Controller doesn't need to know about the Scene, which maintains a nice decoupling.
