Create view dynamically

Please help me find out why the following code gave the error:
ORA-00903: invalid table name
sql_stmt := 'CREATE OR REPLACE VIEW re_temp AS SELECT * FROM :1 || ''.'' || :2 || ''@dbLink ''';
EXECUTE IMMEDIATE sql_stmt USING v_sc, v_tb;
Thanks for your help in advance.

> But, would it be OK?
That depends. Dynamically creating objects in a RDBMS is generally a Bad Idea (tm).
Why?
Stored proc and SQL code will need to use dynamic code in order to access the dynamically created object. This means more moving parts in the code. More complexity. Increase risk of performance problems, run-time errors and nasty bugs.
And as you've seen, you cannot use bind variables with DDL statements and you cannot make object names (like the name of a view or table) a bind variable in DML statements. The result of this will likely be a lot of non-sharable SQL - which is bad news for the SQL shared pool that "loves" sharable SQL and "hates" non-sharable SQL. (non-sharable SQL is often the #1 reason for poor Oracle performance)
Then there are issues such as data integrity. Indexes. Etc. Just how do you deal with these aspects when you are creating dynamic objects?
On a logical design level - just how does your ERD or UML class diagram look like for these dynamic objects? How can you even at a logical level, effectively handle these?
A RDBMS application that uses dynamic objects are almost always fatally flawed.

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:

How to create a dynamic view

I have 5 tables
of which one table is transaction table which stores all the trasanctions
it has near about 30 colms
from which i need create a dynamic view...
where user have to passed 5, 6 parameters and get the result .
how can i create a precompiled view ..

Why do you want to create a dynamic view.
It's a bad practice. You had already all column names.
I think , you can simply create a static view in design time.

How to create a webdynpro view dynamically and embed into view container?

Hi all,
Anyone knows how to create a view dynamically and embed the view into an existing view container?
My layout looks like this:
I have an existing view named main_view.
Inside main_view, I create a view ui container named vcu_view.
I embed the main_view into my window.
I need the codes to create a view dynamically and embed the view into the view container. Anyone have any idea?
Thanks in advance.

A dynamic table based on run-time created view object -- please help!

Hello!
I'm trying to create a dynamic table based on an run-time created view object. All go ok, but table binding component take the first view/iterator state and don't reflect changes they have. Please, take a look:
1. At run-time the view is being replaced by new red-only one based on query in application module:
getQueryView().remove();
createViewObjectFromQueryStmt("QueryView", statement);
2. Page definition file contains an iterator (using iterator or methodIterator - doesn't matter) binding and table, which binds to the iterator, like:
<methodIterator id="distributeQuery1Iter" Binds="distributeQuery1.result"
DataControl="QueryServiceDataControl" RangeSize="10"/>
<table id="distributeQuery11" IterBinding="distributeQuery1Iter"/>
3. The page code uses <af:table>. But, if I use table binding (it's right) like this:
<af:table var="row" value="#{bindings.distributeQuery11.collectionModel}">
<af:forEach items="#{bindings.distributeQuery11.attributeDefs}" var="def">
the table will never changed (i.e. still show the first view instance).
When I tried to use iterator binding directly (it's bad and cannot provide all needed features unlike CollectionModel from table binding) I saw that table works!
(Code is somehing like:
<af:table var="row" value="#{bindings.myIterator.allRowsInRange}">
<af:forEach items="#{bindings.myIterator.attributeDefs}" var="def">
Why the table binding do not reflect changes in iterator? Or should I use different approach?
Thanks in advance!
Ilya.

I got it to work! I used a hybrid approach comprised of some of your code and some of Steve Muench's AcceessAppModuleInBackingBean example.
In the setBindings method, I execute an app module method that redefines the query, then I used your code to delete and recreate bindings and iterator:
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
rebuildVO();
The rebuildVO() method looks like the code you provided in your example:
private void rebuildVO() {
DCDataControl dc;
DispatchAppModule dApp;
DCBindingContainer bc;
DCIteratorBinding it;
OperationBinding operationBinding;
ViewObject vo;
DCControlBinding cb;
try {
bc = getBindingContainer();
dc = bc.findDataControl(DATACONTROL);
dApp = (DispatchAppModule)dc.getDataProvider();
// Execute App Module Method to rebuild VO based upon new SQL Statement.
dApp.setDispatchViewSQL();
vo = dApp.findViewObject(DYNAMIC_VIEW_NAME);
it = bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME);
it.bindRowSetIterator(vo, true);
// logger.info("Remove value binding...");
cb = bc.findCtrlBinding(DYNAMIC_VIEW_NAME);
cb.getDCIteratorBinding().removeValueBinding(cb);
bc.removeControlBinding(cb);
// logger.info("Creating new value binding...");
FacesCtrlRangeBinding dynamicRangeBinding =
new FacesCtrlRangeBinding(null,
bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME), null);
// logger.info("Add control binding...");
bc.addControlBinding(DYNAMIC_VIEW_NAME, dynamicRangeBinding);
} catch (Exception e) {
e.printStackTrace();
And my App Module method that redefines the view object looks like this:
public void setDispatchViewSQL() {
String SQL =
"begin ? := PK_BUsiNESS.F_GETDISPATCHVIEWSQL();end;";
CallableStatement st = null;
String ViewSQL = null;
try {
st = getDBTransaction().createCallableStatement(SQL,
DBTransaction.DEFAULT);
* Register the first bind parameter as our return value of type LONGVARCHAR
st.registerOutParameter(1, OracleTypes.LONGVARCHAR);
st.execute();
ViewSQL = ((OracleCallableStatement) st).getString(1);
findViewObject(DYNAMIC_VO_NAME).remove();
ViewObject vo = createViewObjectFromQueryStmt(DYNAMIC_VO_NAME, ViewSQL);
vo.executeQuery();
} catch (SQLException s) {
throw new JboException(s);
} finally {
try {
st.close();
} catch (SQLException s) {
s.printStackTrace();
When I run it I get my desired results. One thing I don't quite understand is why when the page is first rendered it shows the last set of records rather than the first. Now I have to figure out how to put navigation URLS in each of the table cells.
Thanks for your help; I would not have gotten this far without it,

Dynamically Binding to Dynamically Create View

I tried to copy the code of Dynamically Binding to Dynamically Create View object but something is wrong because when I am debbuging it doesnt work after the sentence vo.executeQuery();
I suspect that the reason could be how I created the view..
Your code is running well but not mine.
It shows this error
JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
null
I dont know why because the code is the same.
How did you create the objet view ?

Create a view dynamically

I would like to create a view dynamically based on “Employee” table
A view in each database should contain every column in “Employee” table except column called “year”. “Employee” table exists in every database but has different columns except “year” column ,so
the employee view should contain different columns based on which database you create a view
How can I create a view dynamically for each database? I am using SQL server 2008 R2

Try this... (Note the @Debug parameter is there to allow you to preview the code before you create the view... 1 to view the dynamically generated code, 0 tt simply execute it.)
DECLARE
@DeBug BIT = 1,
@ColumnString VARCHAR(MAX),
@sql VARCHAR(MAX)
SELECT
@ColumnString = COALESCE(@ColumnString + ',' + CHAR(10) + CHAR(9), '') + c.COLUMN_NAME
FROM
INFORMATION_SCHEMA.COLUMNS c
JOIN INFORMATION_SCHEMA.TABLES t ON c.TABLE_NAME = t.TABLE_NAME AND c.TABLE_SCHEMA = t.TABLE_SCHEMA
WHERE 1 = 1
AND t.TABLE_TYPE = 'BASE TABLE'
AND c.TABLE_NAME = 'Employee'
AND c.COLUMN_NAME <> 'Year'
ORDER BY
c.ORDINAL_POSITION
SET @sql = '
CREATE VIEW dbo.v_Employee
AS
SELECT
' + @ColumnString + '
FROM dbo.Employee'
IF @DeBug = 1
BEGIN
PRINT (@sql)

How to populate list in tree view dynamically

Hi,
I am new to Indesign Plugin creation.
I want to create list in tree view dynamically.
I tried wlistboxcomposite sdk sample in indesign cs4.
I have some doubts in this.
1. Can i write my own method in WLBCmpTreeViewAdapter class because it's implements ListTreeViewAdapter
If it's possible how can i call this method.
2. In this example they populating static string in constructor like this
WLBCmpTreeViewAdapter::WLBCmpTreeViewAdapter(IPMUnknown* boss):ListTreeViewAdapter(boss){
K2Vector<PMString> lists;
for (int32 i = 0; i< 12; i++){PMString name(kWLBCmpItemBaseKey);name.AppendNumber(i+1);name.Translate();lists.push_back(name);}
InterfacePtr<IStringListData> iListData(this, IID_ISTRINGLISTDATA);}
and this list is populating on loading time but my requirement is i have one button "get list" after clicking this button i have to populate the list, how can
i achieve this.
Pls do needful.
Thanks
Arun

The TreeViewAdaptor is responsible for mapping your custom data to the tree view itself. I almost always start by making it return some fixed number of objects with names "item 1" etc. That way you get the tree view working first.
Then, after you get it laid out and displaying properly, you can worry about using real data. At that point, you have your adaptor return the actual number of items in your list and each individual item. Then you can populate your list when you push your button and then invalidate the IControlView of the tree view widget to cause it to redraw. At that point your adaptor will get called and your data should appear.

How to create a Dynamic IAF in WD

Dear all,
We'd like to create a dynamic interactive form based on a XDP in a WebDynpro application. How can we achieve this?
We tried to use setDynamicPDF() and setInteractive(), but it looks like ADS doesn't create a dynamic pdf.
Only the master page is being displayed.
Any ideas how to create a dynamic interactive form via ADS and how to determine if the pdf is a dynamic interactive form (in the browser).
Kind regards,
Noël
version info: Designer 7, NW SP15, Reader 7.0.7.

Hello,
Use the following code to get a dynamic pdf document created in your wdDoModifyView() method. Make use of the firstTime flag there if required :
IWDInteractiveForm iForm =
(IWDInteractiveForm)view.getElement("InteractiveForm1");
iForm.setDynamicPDF(true);
setDynamicPDF(boolean) nmethod has been deprecated in 04. Moving forward to 04s, you will have a different set of APIs to deal with such requirements. Hence the abiove mentioned method will be taken off with the next major release of NetWeaver.
How do you know whether the pdf document created is static or dynamic ? Well, save the form locally and open it in the designer. Go to File > Form Properties > Compatibility Tab. Check your Form Type there.
Best Regards,
Krish

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

CREATE VIEW in ABAP (Open SQL or Native SQL)

Hi all you experts!
I want to create a VIEW in ABAP. I have created Table Views using ABAP Dictionary (in transaction SE11), I don't have any problem with them.
But, what I need is to create a dynamic view, I mean, a view that can be created/replaced (or modified) at runtime. Is this possible with SAP Open SQL, I don't think so... that is why I tried to created using native SQL but it is not working.
Here is the code:
EXEC SQL.
 CREATE VIEW [ZMXRFIV_GLPCA]
 AS SELECT
 T1.GL_SIRID,
 T1.POPER,
 T1.RBUKRS,
 T1.RPRCTR,
 T1.RACCT,
 T1.HSL
 FROM
 GLPCA T1
 INNER JOIN
 SKA1 T2
 ON
 T1.RACCT = T2.SAKNR
 WHERE
 T1.RVERS = '000'
 AND T1.RYEAR = '2008'
 AND T1.KOKRS = 'PI01'
 AND T2.KTOPL = 'PI00'
 AND T2.XBILK <> 'X'.
ENDEXEC.
I have tried using quotes (") for the view name, parenthesis and even using only the name but this make no difference.
Do any of you experts have any idea?
PS: After creating the view I need to do a SELECT INTO TABLE to that view and finally delete this view and continue working with the data on the internal table.

Hi ,
oh yes it is an object (well, how the database should handle it in any context if it wasn't)
i.e. for ORACLE you would have several thousands of them:
select count(*) from dba_objects where object_type ='VIEW'
If you avoid some kind of foreground processing (i.e. pull the data over the network) and handle the processing inside the database it can improve somehow performance a little (i.e. using the retieved rows of the view to stuff into a database table directly). But his may not always possible...

Creating a Dynamic Node for a Dynamic Graphic - Tutorial

Hi everyone,
I'm sharing my first tutorial, hope it'll be helpful for you.
In the Layout tab, it's possible to create an UI element "Business Graphic". It's a very simple tool that only requires a context node with a category attribute (that means, the values that will appear in the 'x' axis) and one or more series (each one with a color, generally a numerical value). It's possible to add a label for each series for better understanding of the Graphic.
Although it's a very powerful tool, there are some problems when we must create a graphic with N series and different labels. If the graphic use an ALV or internal table to fetch data, during runtime we can have more or less series. The definition of a static node and generic series is not enough in this case. That's why I'd like to present you this little tutorial to create a dynamic node that fetchs a dynamic graph:
In the WDDOINIT or Event Handler method that starts the application (once the data is available) we should create the dynamic node in the following way:
DATA: lr_node_info    TYPE REF TO if_wd_context_node_info,
             lt_attributes      TYPE cl_abap_structdescr=>component_table,
             attribute           LIKE LINE OF lt_attributes,
             struct_type       TYPE REF TO cl_abap_structdescr,
             lo_dyn_node    TYPE REF TO if_wd_context_node.
* Let's suppouse we can LOOP at the data table, so we can fetch the
* category data type (for example company name, month, year, ...)
* and each series with a numeric type
attribute-name = 'CATEGORY'.
attribute-type ?= cl_abap_datadescr=>describe_by_name( 'STRING' ).
INSERT attribute INTO TABLE lt_attributes.
attribute-name = 'SERIE1'.
attribute-type ?= cl_abap_datadescr=>describe_by_name( 'I' ).
INSERT attribute INTO TABLE lt_attributes.
attribute-name = 'SERIE2'.
attribute-type ?= cl_abap_datadescr=>describe_by_name( 'I' ).
INSERT attribute INTO TABLE lt_attributes.
* Once we have all the attributs for the node, we create a formal structure
struct_type = cl_abap_structdescr=>create( lt_attributes ).
* Now we can get the context information to add a new node
lr_node_info = wd_context->get_node_info( ).
* Create the node
lr_node_info = lr_node_info->add_new_child_node(
                    name = 'GRPH_DYN'
                    IS_MANDATORY = ABAP_false
                    IS_MULTIPLE = ABAP_true
                    STATIC_ELEMENT_RTTI = struct_type
                    IS_STATIC = ABAP_false ).
* Now we should populates the node, I'll create a hardcoded table,
* simulating the internal table that you should already have
TYPES: BEGIN OF tw_alv,
                    category TYPE string,
                   SERIE1    TYPE i,
                   SERIE2    TYPE i,
                END OF tw_alv.
TYPES: tt_alv TYPE STANDARD TABLE OF tw_alv.
DATA: lw_alv TYPE tw_alv,
              lt_alv   TYPE tt_alv.
lw_alv-category = 'Alfa'.
lw_alv-serie1   = 3.
lw_alv-serie2   = 8.
APPEND lw_alv TO lt_alv.
lw_alv-category = 'Beta'.
lw_alv-serie1   = 4.
lw_alv-serie2   = 4.
APPEND lw_alv TO lt_alv.
lw_alv-category = 'Gamma'.
lw_alv-serie1   = 1.
lw_alv-serie2   = 3.
APPEND lw_alv TO lt_alv.
* Now let's call the recently created node and bind the lt_alv table.
* Get node from context
lo_dyn_node = wd_context->get_child_node( name = 'GRPH_DYN' ).
* Bind table with ALV Container
CALL METHOD lo_dyn_node->bind_table
    EXPORTING
      new_items = lt_alv.
* It's always good to check if the table was succesfully binded.
* I refresh the lt_alv table and get the values from the node for controlling
REFRESH lt_alv.
lo_dyn_node->get_static_attributes_table( IMPORTING table = lt_alv ).
There are other ways of adding a node structure in the method add_new_child_node, but it works for me only with STATIC_ELEMENT_RTTI. The node is now created and has the data required for the graphic. Now, we should go to WDDOONMODIFYVIEW, or save the target view as a parameter, to create the graphic, bind the category and series and show it on the screen.
DATA: lr_graph       TYPE REF TO cl_wd_business_graphics,
              lr_cat           TYPE REF TO cl_wd_category,
              lr_series1    TYPE REF TO cl_wd_simple_series,
              lr_series2    TYPE REF TO cl_wd_simple_series,
              lr_container TYPE REF TO cl_wd_uielement_container,
              lr_flow         TYPE REF TO cl_wd_flow_data.
* Get the root element from the Layout or the specific
* container you have created for the graphic
lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
* Creates a line busniess graph
lr_graph = cl_wd_business_graphics=>new_business_graphics(
        BIND_SERIES_SOURCE = 'GRPH_DYN'
        CHART_TYPE = cl_wd_business_graphics=>e_chart_type-lines
        HEIGHT = 340
        WIDTH = 750
        ID = 'GRAPH' ).
* Create the flow data for the new UI Element business graphic
lr_flow = cl_wd_flow_data=>new_flow_data( element = lr_graph ).
* Set graph in the root container from the Layout tab
lr_container->add_child( lr_graph ).
* Bind the category from the dynamic node to the dynamic graphic
lr_cat = cl_wd_category=>new_category(
                  view = view
                  bind_description = 'GRPH_DYN.CATEGORY'
                  tooltip = 'Company Name' ).
lr_graph->set_category( lr_cat ).
* Bind the two series from the dynamic node to the dynamic graphic
lr_series1 = cl_wd_simple_series=>new_simple_series(
                  bind_value = 'GRPH_DYN.SERIE1'
                  label = 'Sales'
                  view = view
                  tooltip = 'Average Sales' ).
lr_graph->add_series( lr_series1 ).
lr_series2 = cl_wd_simple_series=>new_simple_series(
                  bind_value = 'GRPH_DYN.SERIE2'
                  label = 'Purchases'
                  view = view
                  tooltip = 'Average Purchases' ).
lr_graph->add_series( lr_series2 ).
Finally we have created our business graphic. Test the application and you'll see something like the attached image.
Hope you'll find it useful.
