Checkbox in Query component

I have field in one of my VO which can contain only two values "Y" and "N". Now i created bounded query component by dragging All querable attributes for that VO to jspx page. I mentioned UI control type checkbox for this field. But now i m not finding any help how to map "true" to "Y" and "false" to "N" because checkbox is selected, it assigns value "true" but i have in db is "Y" for that. Kindly help me. I also tried to intercept query programmatically in my ViewObjectImpl class by overriding executeQueryForCollection but did not gain success because i was not able to find parameter there.

OK, you guys are correct - I should read the question a bit better before answering - I just saw the buzzword "transient attribute" in mkonio's answer and responded to that. I do believe that mkonio's solution will work; if you expect to do that type of query a lot, you may have to look into creating a function-based index in the database for performance reasons. I haven't dived into the inner workings of the af:query component too much yet, but it looks like the Query Descriptor object is where this kind of magic could happen, although I can't yet see an obvious way to customize/extend the inferred internal one that Oracle provides for business components. Perhaps someone else can comment on that?
Best,
John

In af:query component , need to make Match option invisble

Hi,
i am using af:query component and do not want to show the Match with radio button options (All, Any).
Can anyone suggest how to achieve this.

You use view criteria, as this is what af:query is for. You use 'All queryable Attributes' which is an implicit view criteria.
There is no easy way (I don't know one) to remove the 'Match all/any' radio button other than the way Luc described. In your case you have to build a view criteria like the 'All queryable Attributes' to get to the switch in the UI hint tab of the view criteria.
To do this you create a new criteria and add all attributes you want to one group without specifying and literal or bind variable and use an operator like StartWith for strings and equal for numbers. Then uncheck the 'Show Match all Any' checkbox and use this view criteria for your af:query.

Hi,
Please go through the tutorial "Understanding scope and managed beans". This is available at:

The details of the selected items need to be stored in an object that is in session scope.
Hope this helps

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.

Setting default value read from user session, for an LOV in Query component

I want to set the default value of a field in VO that participates in a named view criteria and thereby in Query component. That field is configured with an LOV by mean of a view accessor. The values are Y and N and the corresponding display strings obtained from view accessor are true and false respectively.
I am able to set the default value by setting the value of the criteria item corresponding to that field in view criteria. I am setting the value as either Y or N and I am able to corresponding display string as per the view accessor, on the query component when it is rendered.
I want to read the defauilt value from the ADF BC user session and set it as default value. I tried setting the values as "adf.userSession.userData.usageFlag". Iam ensuring that the attribute usageFlag is set before the view activity that has the query component is invoked. But this is ending up showing no default value in the Query component when rendered.
Can any one let me know how to go about with this?

I made up your table since you didn't provide some example, but I'm sure this will give you the picture:

Incorrect operators in af:query component

We have created a search popup using af:query component based on a view criteria.
The view criteria uses two string[varchar2(60) in EO] attributes named "Name" and "Owner".
TerritorySearchViewCriteria
Group
Name CONTAINS :BindTerritoryName -- String in VO, Varchar2(60) in EO
AND Owner CONTAINS :BindOwnerName -- String in VO, varchar2(360) in EO
Issue:
The operators drop down shows some irrelevant search operators(not meaningful to strings) such as "BETWEEN",
"NOT BETWEEN", "BEFORE", "AFTER", "ON OR AFTER" and "ON OR BEFORE". Because of this we are seeing some unexpected
search results when this operators are used for searching.
On looking at the Bali site and BLAF guidelines page it clearly states that the list of operators for string are
"EQUALS", "NOT EQUALS", "STARTS WITH", "ENDS WITH", "CONTAINS", "DOES NOT CONTAIN", "LIKE", "IS BLANK" and "IS NOT
BLANK".

As per the guidelines mentioned for String, You could remove the unwanted operators from the view criteria item.
The example below shows - how the unwanted operators namely BETWEEN & NOTBETWEEN could be removed.
For more details, look into the following section 27.3.3 in the developer's guide:

Add custom field to af:query component?

Anyone had any experience overriding af:query copmonent? I need to add my custom search field (to query component), which would have a search icon next to it, and on click, a popup widow would open containing my custom task flow where I could select a record with certain value and on return that custom field (in query component) would get populated with selected value. I hope I'm being clear. Please point me to any useful information. Is that even possible? I use JDeveloper 11.1.2.3.4.0 Regards, Marko

Hi,
af:query is a component that comes as is. Its not designed for customization in that you can add your own fields. If you have a requirement for this then
1. expose a method on the VO Impl or AM Impl that expect arguments (your query parameters)
2. Use the arguments to populate bind variables used by a ViewCriteria
3. Apply the View Criteria to the View Object
4. Execte the View Object
5. Drag and drop the method from the DC panel as a parameter form
6. Ensure the result table PartialTrigger property is pointing to the button ID of the parameter form
7. Change whatever UI component you want to change in the parameter form
This gets you going ...

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).

Programmatically Load Query Component on Page Load

Hi All.
We have a requirement in which we need to populate the fields of a query component and execute the query...upon loading of the page.
Our use case:
We have a page in which there is an analytic showing counts of requests in different status (i.e. Open, Closed, In Process).
Status Count
==== ====
Closed _5_
Open _3_
In Process _6_
When the user clicks on the count (which is a hyperlink) we want to take them to the "Search for Requests" page with the criteria filled out and the query automatically executed. For example, if the user clicks on the count of "5" (for Closed)....they will be transferred to the "Search for Requests" page. The query field of "Status" will be defaulted with "Closed" and the query automatically executed (with the 5 requests shown in the result set).
We are using page fragments (.jsff) in bounded ADF task flows.
I am thinking that we need to set up a default activity in the "Search for Requests" task flow that will call the AM Impl method to handle this on the model side but I am unclear on how to programmatically set the criteria that is used in a query component?
Any help is appreciated.
Thanks.

In the processRequest of your controller you can invoke a method in the AM which in turn invokes a method in the Search VO which sets the where clause and executes the query.

How to access filled in values of an af:query component

Hi,
I have a viewobject with a viewcriteria defined on it. The results are showed in a result table. When a user selects a row from the result table a new page is showed with detail data. In that page i would like to show the user the filled in attributes with their values to remember the user to which search criteria the results correspond. How can i access the attributes with their values of a af:query component?
Kind Regards,
Andre

Hi Andre,
maybe you can try Frank's approach: http://www.oracle.com/technology/products/jdev/tips/fnimphius/AdfCodingQuickies.html
I just tested for RichInputText:

        return null;
    private void parseQuery(UIComponent component){
      List<UIComponent> list = component.getChildren();
        for (UIComponent com : list){
         if (!(com instanceof RichInputText)){
           parseQuery(com);
         else{
            if (((RichInputText)com).getValue() != null) System.out.println( ((RichInputText)com).getId() + " : " + ((RichInputText)com).getValue() );
    }but the problem is with getLabel() - it will return null

Need Information on af:query component

Hi,
I need some information on the <af:query> component in JDev 11g.
When using ADF 11g's new component, ADF Query (af:query) whether the default "All Queryable Attributes" or on other newly defined View Criterias:
1     What are the disadvantages of this component, given that the result-set - without filtering - is large (between 1350 and 1700 rows, approximately).
2     Does it fetch all rows from the database, then performs filtering upon user's entered search criteria – i.e., hitting the "search" button?
3     Is there a way to add client-side validation on the search criteria attributes?
4     In general: What is the best practice to implement a Search Form in ADF 11g
Kindly provide your inputs for the same.
Thanks,
Vineet

2     Does it fetch all rows from the database, then performs filtering upon user's entered search criteria – i.e., hitting the "search" button? You could tune your VO not to exeute the query by default (i.e., before applying a search criteria)
check this blog for sample: http://andrejusb-samples.blogspot.com/2009/08/jdevadf-sample-oracle-adf-tuning.html
As an other option, you could have a default view criteria applied and executed to filter to result set if it is applicable for your usecase.
3     Is there a way to add client-side validation on the search criteria attributes?I'm not sure about this though.

In addition check this sample as well. It might be of help: http://andrejusb-samples.blogspot.com/2009/09/jdevadf-sample-programmatical-reset-for.html

Query regarding : af:query component

In af:query my requirement is to add one search field which looks like :
"*Label*" "*Drop down List*" "*Input Text field*"
For the other fields which have only
"Label" and one other Component type i am using QueryDefinition.addAttributeDefinition But how to add two components with Label.

Not sure if you can change the af:query component to do this , but you can easily build your own search form and in this form build your own layout.

Af:query component and persisting preference to database

I am using af:query component for search functionality and that component has an saving preference option to store the preference in session. I would like to store/persist the preference to database and retreive them and show to the user when they come next time.
Could you please let me know, how to accomplish this?
Thanks

Ejsp2000,
In order to do this, you need MDS, which didn't make it into this release of JDeveloper.
I asked this very question a month or so back - you may be able to find it by searching.
