Guide me to override the af:query component QueryListener property

Hi All,
If any one have sample application to override the af:query component query lisenere proprety, please share. I have the following requirement in search criteria.
Field 1
Field 2
Field 3
Field 4
Field 5
Find Button
Result section
Validations on these fields:
1. When user enters value in field 1 and tabs out, a background plsql should execute and return the value to field 2. If no value returns, then and exceptio should raise for field1.
2. Field 3: when the user enters a value and tabs out, it should automatically convert to UPPER case.
3. Field 5 and field 4 are date paremeters. Field 5 should be disabled until a value enters in field4
4. Value in field 5 should be validated agaigst field 4 it should always > field 5
5. Once user hits find button, it should check for atlease one search criteria other wise it should prompt the user to enter atlease one search criteria. (ALong with above 5 validations). Popup should come here.
Any suggestions would be appricated.

I'm not sure you'll be able to achieve all of this with the af:query component.
Here is how to do the dependent lists:

It might be easier to build this type of search form something like executeWithParams - see:

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.

Accessing fields of the af:Query Component

Hi all,
I need to get the value of a dynamic field that is added to the query component at runtime.
In my application there is field named "Member Id" which adds a "select one component" in the advanced search mode.
This "select one component" has a string value "self".
What I need to do is,
When the value "self" is selected from the "select one component" I need to use the Id of the user
as the "Member Id" for the search query.
Is it possible achive this by using af:query component ? or is there a different approch?
I'm using JDeveloper 11.1.1.0.1
Thanks,
Melaka

Melaka,
first create a custom View Object Class for your View Object from the Java Classes pane. Then override the buildQuery() method of the ViewObjectImpl by writing the following code:
@Override
protected String buildQuery(int noUserParams, boolean forRowCount) {
// call super.buildQuery() to allow the framework to build the query
String query = super.buildQuery(noUserParams, forRowCount);
// here you will modify the query
// if the query contains your keyword
if (query.contains("'self'")) {
// replace it with the actual user id
// return the modified query
return query;
I am sure there are other cleaner ways to accomplish this.
Consider for example using two separate attributes: one Transient for your "Member Id" query criteria - what is shown to the user - and another attribute actually mapped to a column that is used for querying. You set the value of the second attribute as the first one changes.

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.

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

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

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.

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.

Timezone effects on Date and Timestamp fields in af:query component

Hello,
I'm working on an ADF application where time zone is configured as follows:
* Dynamic View Layer time zone is configured in trinidad-config.xml file and bound to a session scoped value:
<trinidad-config>
<skin-family>fusionFx</skin-family>
<time-zone>#{sessionScope.tz}</time-zone>
</trinidad-config>* ADF BC time zone is configured in adf-config.xml file and bound to View Layer time zone:
<adf-config>
<user-time-zone-config xmlns="http://xmlns.oracle.com/adf/usertimezone/config">
<user-timezone expression="#{adfFacesContext.timeZone.ID}"/>
</user-time-zone-config>
</adf-config>The problem here is that Dates and Timestamp values work as expected all over the application except for the af:query component. When displayed as af:inputDate in af:form, Dates and Timestamp values are NOT getting converted to the time zone (TZ) configured in trinidad-config.xml file, whereas TimestampTz and TimestampLtz are. However, when displayed in af:query component, Dates and Timestamp values are automatically converted to View Layer TZ after a search has been performed.
For example, say View Layer TZ = US/Pacific and we enter 01/jun/2011 as a search criteria of type Date and then click on the Search button. The displayed value automatically changes to 25/nov/2011, that is, it gets converted to the WLS JVM time zone, which is set to Europe/London.
Is conversion of Date and Timestamps in af:query component the expected behaviour or could this be a bug?
Is there any way to avoid this conversion?
Thanks in advance

All help would be greatly appreciated.

Reorder Saved Search items in af:query component

Hi,
Is there any way to change the order of Saved Searches listed in the af:query component. The order that the view criteria are displayed in this component does not seem to have any relationship to the order that they occur in the VO.xml file, nor are they listed alphabetically.
I'm only interested in ordering the view criteria in the choice list, that I have configured at design time.
Is this possible?

forgot to mention in my initial post that I'm using Jdeveloper 11g Rel 1.
Thanks,

Search error-Query component status initialzing

When I try to search anything on my sharepoint site its is showing Internal Server Exception.
When I looked into the Central Administartion->Search Service:Search Administration,the Query Component 0 status is stuck on
initilialzing.So how can I solve this and make the query component 0 online.

Try Moving the Query Components
Open SharePoint 2010 Central Administration.
Select Managed service applications under Application Management.
On the Services Applications page, select the Search Service Application.
On the Search Administration page, locate the Search Application Topology section and click Modify.
On the Topology for Search Service Application: Search Service Application page, locate the Index Partition category. (The default Query Component
is typically named Query Component 0). Click Query Component 0 and then click Edit Properties.
On the Edit Query Component page, select a server in the topology from the Server drop-down list and then click OK. This will move the Query
Component to the selected server.
If the query status still shows "initializing"
Run the commands below to check the Query status as per article
http://help.outlook.com/en-us/140/ff607963.aspx
PS C:\Users\Administrator> $qc = Get-SpEnterpriseSearchQueryComponent -QueryTopology and then run the command
then run the command to set the status to active as per article:
http://help.outlook.com/en-us/140/ff607665.aspx
PS C:\Users\Administrator> $qc = Get-SpEnterpriseSearchQueryComponent -Identity [identity] -Active
and then the status by running
PS C:\Users\Administrator> $qc | fl Name, State
If it is showing initializing then delete the current SSA and created a new one by following an article:

Query Component - Flexible Conjunction

I have a requirement to query data using Query component with the flexibility for the conjunction to be used. For example,
If I have 3 fields to query (note that in advance mode, rather either using All or Any (AND and OR), I would like to provide the flexibility to allow user to determine which conjunction to use:
A = x OR B = y AND C = z
or
(A = x OR B = y) AND C = z
Thanks.

Please state the version of JDeveloper you're using when posting to this forum. I'll assume JDev 11g.
The af:query component does not support what you're looking for. In your case you'll need to build something out of the more basic components yourself.
