Query component using toplink.

Hi,
I am trying to implement query component with toplink entity. Please provide any document or sample application related to this.
Thanks in advance.

Have you tried a simple search (http://www.oracle.com/pls/as111210/search?word=toplink) which get you http://docs.oracle.com/cd/E24382_01/user.1112/e17455/dev_toplink.htm#OJDUG1094

Multiple queries happeing in adf query component using LOV

Hi,
I am using a programmatic view object in adf query component and have created List of values for one attribute by adding another programmatic ViewObject as ViewAccessor.
To populate the lov ViewObject, i have overwritten the method executeQueryForCollection in which i call the webservice to fetch the data. So lov is working fine inside QueryComponent.
I have overwritten queryListener attribute of query component in my backing bean. In the queryListener method, to populate the result grid, am populating the view object by using createRow and insertRow apis. While doing so, Whenever i do setAttibute for the lov field, the overwrittern method executeQueryForCollection getting invoked. Hence my webService getting invoked. So if i have 10 rows, the webservice is getting invoked 10 times.
I put sops in the executeQueryForCollection method for the queryMode and getName.
System.out.println("executeQueryForCollection::::"+this.getQueryMode()); i get as 7
System.out.println("executeQueryForCollection:::=" +this.getName()); i get as CurrencySummaryLOVVO_5708_findByVC_ The number 5708 varies for every row.
Please tell me How to avoid invoking the executeQueryForCollection everytime when i do setAttribute.
One workaround i have currently is to have one dummry attribute for the lov which can be used for display in grid and actual attribute will be used in Query Component for the lov to function.
Is there any other better workaround?
Thanks a lot in Advance.

When you set a value to LOV field it tries to validate it from the LOV data. thats why it execute query.
Try setting Row Level Bind Values = false for the accessor.
yet, i would suggest to find an other way to populate values of LOV since the executeQueryForCollection will be executed many times when you use that LOV:

Dynamic Query Mapping using Toplink Entity

Hi,
We have a requirement that the column names of the table dynamically gets changed for different customers.
eg;
Client 1 , will have
Select EMP_ID, EMP_NAME from EMPLOYEE
Client 2 will have
SELECT CEMP_ID, EMP_NAME, CEMP_ADDR from EMPLOYEE
Is it possible to make a Toplink Entity Employee object to support both the queries at runtime ?ie; we should not modify the java entity object for each customer.
With normal JDBC , we can perform SELECT * from EMPLOYEE ,get the resultset , and using metadata , we can find the column names and process it accordingly.
Is this functionality possible with toplink JPA at all ?
Thanks

Hi,
I am trying to use DynamicEntity class. Is Joined Table Inheritance supported in DynamicEntity ? Since I need to create an HybridEntity on the fly by selecting all the fields from TABLE A and TABLE B by joining key fields, whose fields will dynamically change based upon the customer. Below is what I am currently trying to do. But the Entity Object that I got contains fields only from TABLE A and not from TABLE B
EntityManagerFactory emf = new EntityManagerFactoryImpl(setup,EclipseLinkJPATest.getEMFProperties());
SchemaManager manager = new SchemaManager(JpaHelper.getServerSession(emf));
Vector <DatabaseRecord>tableAEntityFieldNames = manager.getAllColumnNames("TABLE A");
Vector <DatabaseRecord>tableBFieldNames = manager.getAllColumnNames("TABLE B");
EntityType tableAType = EntityTypeFactory.create("TableAEntity","DynamicEntity$TableAEntity", "TABLE A", loader);
String columnName = null;
for(DatabaseRecord tableAObj: tableAEntityFieldNames){
columnName = tableAObj.get("COLUMN_NAME").toString();
EntityTypeFactory.addBasicProperty(tableAType, columnName, columnName,
"TABLE A_ID".equals(columnName) ? Long.class : String.class, "TABLE A_ID".equals(columnName) ? true : false);
EntityTypeFactory.addToPersistenceUnit(emf, tableAType);
EntityType stepType = EntityTypeFactory.create("TableBEntity","DynamicEntity$TableBEntity", "TABLE B", loader);
for(DatabaseRecord tableBObj: tableBEntityFieldNames) {
columnName = tableBObj.get("COLUMN_NAME").toString();
EntityTypeFactory.addBasicProperty(tableBType, columnName, columnName,"TABLE B_ID".equals(columnName) ? Long.class : String.class, "TABLE B_ID".equals(columnName) ? true : false);
EntityTypeFactory.addToPersistenceUnit(emf, tableBType);
EntityManager em = emf.createEntityManager();
List <DynamicEntity> entityList = null;
entityList = em.createQuery("select s from TableAEntity s, TableBEntity st where s.TABLE A_ID= st.TABLE B_IDand s.TABLE A_ID=?1")
.setParameter(1, 1397)
.getResultList();
System.out.println("entityList..."+entityList);

Is it possible to use the af:query component with programmatic VOs?

My understanding is that the view criteria in a normal SQL-based VO are used to add WHERE clauses to the VO.
Since programmatic VOs do no have this capability, is there something I need to override in the view object implementation class to support the view criteria that will be established by the af:query component?
Does someone have an example of how this might be done?
Thanks, -Klaus

Unfortunately no. The remote control will work, but the radio will not.
The radio only works with the iPod video and the nano.

How to use my Declarative Component in query component ???

Hi everybody,
I want to change inputDate in query component to my declarative component for Date fields. I did not find any way except implementing the Model of Query component so read "Web User Interface Developer’s Guide for Oracle Application Development Framework 11g Release 1 (11.1.1) " document and use the ADF Faces Demo Application. now I don't know can I change type of search component to my declarative component in DemoQueryBean class ??
the code of oracle.adfdemo.view.query.rich.DemoQueryBean that I changed is :
public static final ComponentType myDatecomponent=ComponentType.valueOf("myDate");
private void _createPageDef()
_pageDef = new DemoPageDef();
_pageDef.addAttributeDef("Ename",
"Employee Name",
"Full name of the Employee [Last Name, First Name]",
String.class,
persianDate,
false, null, true, true, true);
As you can see I changeed type of Employee Name component to my Component but I see below exceptions :

I think these exceptions happend because of there is not any constant of AttributeDescriptor$ComponentType in ComponentType class for myDate component.
I try to create a class and extends ContentType and add my component type to it but I can't. is there any way for solving this problem ?
please help me :(
Thanks.

Hi,
saying it this way: There is no native option to do this. Since I never tried hacking into the framework classes, I can't say if there is a glimpse of hope for you

How can I use FK description in a BC4J data query component?

Hi all,
I am facing the following problem.
Although I use renderers in the DataEdit component for displaying the descriptions of the FKs this is not useful for the BC4J data query components.
How can I get the same functionality as in the dataEdit components?
Thanks in advance,
Aggelos

Anfortunately,
This is not the same when I have a DataQuery component.
The question now becomes as following:

Using quick query component

hi,
I am using quick query component. There is any way to show in the combo box of the quick query component only some and not all fields, because I do not need to display all.
Please..

Vane,
If you're using ADF Business Components - I believe you can do this by creating a named view criteria on your View Object and then dragging-and-dropping the named view criteria on to the page as an af:quickQuery - haven't tested this personally, though.
A really quick test - no more time today - seems to show that named view criteria can create an af:query, but I didn't see af:quickQuery as an option...
Time to read the Fusion Developer's Guide, I guess.

Update Query using Toplink

I would like to fire an update query using Toplink mapping objects. The
structure of the Query would be like
update <<table name>>
set <<col name A>> = 'Y'
where <<col name B>> in (<<valA>>,<<valB>>............);
ValA, ValB.... are dynamic values passed from my front end Java App
Can anyone help me in this regard...........

Karthik,
This is new functionality added in 10.1.3. You will want to look at UpdateAllQuery.

How to do linguistic sort query using Toplink API

Hi,
I want to write a Toplink query using linguistic sort like the following SQL,
SELECT * from emp_name
where ename LIKE 'müller%'
ORDER BY NLSSORT(ename, 'NLS_SORT=german')
I got two questions:
(1) how to implement "ORDER BY NLSSORT(name, 'NLS_SORT=german')" using Toplink API.
(2) I built linguistic index,
CREATE INDEX nls_index ON emp_name (NLSSORT(ename, 'NLS_SORT = german'));
But SQL plan shows that LIKE clause does not use index. I wonder how to enforce query with LIKE clause to use such linguistic index.
Thanks for your help in advance.
-Evan

Looks like we can not do an exact word search using Java API.

Class Cast exception when clicking Search Button in Query component

Hi
We have to implement the Query component in ADF programmatically.. We are using Toplink as the Model layer for ADF.
We followed the Web User Interface Guide for ADF development, Chapter 12 (Using Query Components) for the same.
We already have implemented the following classes:
1) QueryModel
2) QueryDescriptor
3) AttributeDescriptor
4) ConjuctionCriterion
5) AttributeCriterion etc.
We are able to see the Search panel in UI with selected fields in Basic as well as Advanced mode.
When we click on Search button, we are getting Class Cast exception.
The stacktrace of the exception is below:

I am working on a project that utilize Oracle Ultra Search that will crawl and tag documents in the database.
The initial code that uses pure JDBC was working fine, but when we switch to get database connection from dataSource, we are getting classCast exception inside Oracle's ultra search. The problems is that the class we get from dataSource.getConnection() returns
"weblogic.jdbc.wrapper.JTSConnection_oracle_jdbc_driver_T4CConnection". But Oracle UltraSearch is not expecting that.
Is there anyway to unwrap the connection that we get from dataSource ? I tried casting to OracleConnection,
assign the connection to "oracle.jdbc.driver.T4CConnection" without any success.
Any help would be appricated.
ThanksHi Gary. If the code you want to run is running inside WebLogic, such as in a JSP,
then look for our documentation on our JDBC extension 'getVendorConnection()". It
will get you a direct Oracle connection for their mis-declared UltraSearch
classes (they declare they take java.sql.Connection, but they really demand a
concrete thin driver connection. No other Oracle driver will be given a chance).

How can I use TopLink for querys that have two and more tables?

I use TopLink today, and I can use one table to query, but how can I use TopLink for querys that have two and more tables?
Thank you for see and answer this question.

You can write a custom SQL query and map it to an object as needed. You can also use the Toplink query language "anyOf" or "get" commands to map two tables as long as you map them as one to one (get command) or one to many (anyOf command) in the toplink mapping workbench.

Error while creating query component

Hi,
I working in a production environment where I have 2 application servers, 2 query servers and 2 crawling servers. I have created the search service application on the application server with the default topology then I modified the topology to add the crawl
components on the crawl servers successfully.
Now I have an issue creating new or modifying the current query components. Every time i try the create new query component I receive the below issue. The query server is having the services "SharePoint Server Search" and "Search Query and

Are you creating the new topology using Central Administration or PowerShell?
It looks like there is an issue synchronizing the search configuration files in the share.

i think u have missed it.
RSZCOMPDIR IS THE ONLY TABLE WHICH PROVIDES THE DATA.
ENTER TECHNICAL QUERY Name in RSZCOMPDIR-COMPID.
RSZCOMPDIR-TSTNAM gives you the user id of sap bw user who made the change.
RSZCOMPDIR-TSTPDAT gives you date on which change was made .
RSZCOMPDIR-TSTPTIM gives you timestamp on which change was made .
all users details can be obtained from TCODE SU01 where you need to enter sap user id.
You can also get user name( description) by using tcode SE09 and entering above sap user id.

Query component using toplink.
