View Criteria and Transient fields

Hello, I was wondering, is it possible to have View Criteria set on a Transient field? I have created a Transient field named "Field1". I then go to the Query tab in my ViewObject and select the option "Create new view criteria". Here I select the option "Add Item" and from Attribute list I select my field "Field1". However what I notice is that the "View Object Where Clause" does not get updated when the attribute I select is a transient field - when it is a normal field (i.e. from an Entity) it does get updated. This means that I am unable to create view criteria for transient fields. Is there a way how I can manage to do this?

Transient attributes are not based on database columns. This means that WHERE-clause on transient attributes is a non-sense. It makes sense to add conditions on transient attributes only if the view criteria will be executed as a filter in memory (see the "Query Execution Mode" property in the "Create View Criteria" dialog).

View criteria and LOVs

Hi I am very new to ADF and just getting started on view criteria and LOVs. Is it possible to create a query panel and table such that in the search section the fields have drop down boxes or select many shuttles ? Right now what ever criteria i give is coming as only text boxes. I want for some fields there must be values retrieved from database and shown as drop down list and for another field I need it to be shown as SelectManyShuttle.
Any suggestions or examples should be helpful.
Thanks,
Ravi.

Hi Ravi,
Sure, there is a way to do this. The attributes in your ViewCriteria should have LOV defined on them to show dropdown list for that attribute. When you include that attribute in your VC, it will show as selectOneChoice or whatever you have defined the LOV as.
This might help:

How to reset view criteria in transient view object

Hi,
I have a view object with one transient attribute:
ViewCriteria vc = null;
ViewCriteriaRow vcRow = null;
ViewObject vo = am.findViewObject("TestView");
vo.setQueryMode(ViewObject.QUERY_MODE_SCAN_VIEW_ROWS);
Row newRow1 = vo.createRow();
newRow1.setAttribute("TestAttr", new Number(10));
vo.insertRow(newRow1);
Row newRow2 = vo.createRow();
newRow2.setAttribute("TestAttr", new Number(20));
vo.insertRow(newRow2);
ViewCriteria vc = null;
ViewCriteriaRow vcRow = null;
vc = vo.createViewCriteria();
vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE);
vcRow = vc.createViewCriteriaRow();
vcRow.setAttribute("TestAttr", new Number(10));
vc.addElement(vcRow);
vo.applyViewCriteria(vc);
vo.executeQuery();
System.out.println("Rows: "+vo.getEstimatedRowCount()); // Works as expected
vo.getViewCriteria().resetCriteria(); // This code should reset view criteria
vc = vo.createViewCriteria();
vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE);
vcRow = vc.createViewCriteriaRow();
vcRow.setAttribute("TestAttr", new Number(20));
vc.addElement(vcRow);
vo.applyViewCriteria(vc);
vo.executeQuery();
System.out.println("Rows: "+vo.getEstimatedRowCount()); // Returns 0 rows - should return 1How to reset and apply view criteria ?

try to remove the previously view criteria. ie
ViewObjectImpl vo = this.getSomeViewObject();
ViewCriteria vc = vo.getViewCriteria("criteria_name");
vo.removeViewCriteria("criteria_name");
vc.resetCriteria();
vo.applyViewCriteria(vc);

Named View Criteria and Range paging don't work together

Hi,
I am using a named view criteria for a view whose access mode is set to range paging.
When I use the named view criteria on my page to do a search I am getting the below error. If I don't use range paging as access mode for the view I don't get this error. Looks like when I use the search it doesn't pass the row numbers properly and they are not set in the query.
Is this a known issue or am I missing something?
Thanks

Hi Frank,
I didn't test it in 10g. It was something that I came across and thought that it might be a known issue..
The query is not something that I built manually. My entity is created from a table and my view is using the entity. I added a Named Criteria to the view and used Range Paging as access mode for the view.
The actual query is this
SELECT Persons.PRINCIPAL_NAME,
       Persons.PERSON_ID,
       Persons.TITLE,
       Persons.FIRST_NAME,
       Persons.LAST_NAME,
       Persons.PHONE_NUMBER
FROM PERSONS Persons

View Key and Similar field

Hello friends,
I am creating a view here and its based on MHIS and MHIO tables.I have 2 questions.
They both have 2 fields as their common keyfields.Of which table should i use in my view.
Secondly the 2 tables also have fields like tsenq and usermod common between the two and obviously i cant have both.How should i know which one tables field should i select.
Thanks.

Hi Ronit,
Are u going u join both the table in ur View?
In database view u can just give the table name MHIS and MHIO in Tables field and give the link betwenn the tables in Join conditions field. And in View fields Tab u can select the fields which u want to view in the output by clickink on the push button Table fields. Here u get both the table names MHIS and MHIO, u need to select teh table name and choose the fields related to that.
If u are going to use only one table in ur View.
give the table name in the Tables Field and in the View fields Tab click on the Table fields Push button here u get teh list of fields related to the table u have mentione din the Table/Join condition Tab

Crystal Reports Viewer 2008 and parameter fields

Hello,
I saw this product on the main Crystal Reports site this afternoon and decided to download it to try it out. I have a number of users who would benefit from being able to preview their report results prior to actually running the report. This seems like the perfect product. I have a large number of Crystal Reports which were created in Crystal version XI. I also downloaded the free 30 day version of Crystal Reports 2008 yesterday to see what new features are there.
While testing Crystal Reports Viewer, I tried to run one of my reports which needs a parameter to run properly (account number). This type of parameter is needed for probably 98% of this business' reports.
The problem: Crystal Reports Viewer does not prompt me to input the parameter. In my actual Crystal Report, I had the box "Save Data with Report' left unchecked, as the account number frequently changes. However, if that box is left unchecked, Crystal Reports Viewer will give me the error message "No Saved Data. This report file does not contain saved data and cannot be viewed. To get data into the report, please open and re-save it in the Crystal Reports designer application with the "Save Data with Report" option selected."
Thinking that possibly it was the version of Crystal Reports in which the report was created (XI), I downloaded the free trial of Crystal 2008 and created a very simple test report with one parameter for account number where the account number is retrieved from our database. And I am having the same trouble.
The "Help" section of Crystal Reports Viewer tells me that I can select my parameters in the parameter panel. I do not see anything in my parameter panel other than the words "Current Data Set Last refreshed: 04/12/10 2:58 PM". The help tells me that I can "select the parameter directly in this panel by entering a new value", but there is no option to do so.
Any help would be appreciated.
thanks,
Noel

What I've learned is that I was originally using Crystal Viewer XI and upon opening it I received a message indicating there was an update.
I ran the update which put me on Crystal Viewer 2008.
Since then I have not been able to refresh my screen to bring up the parameters.
See the attached forum for another post concerning this same issue.

View criteria with date field in ADF

Hi ADF Experts,
I have a requirement like.I have a VO with query let say "Select * from Employee"
I have created viewCriteria in that VO like "HireDate between 'abc' and 'XYZ'.
In AMImpl class I have written, one fuction to apply viewcriteria on VO and execute query.
Expose that function as service method, and execution form backing bean.
It is working properly for all other column except the date field.(May be beause of date format, as we cannot apply To_Char, or ToDate in view criterai for date format)
Tried all possible combination but no luck
Please help

View Criteria non required field

Hello,
I have a view object with a viewCriteria with the following condition: No between no1_prm and no2_prm, the condition for required is optional and I checked ignore null values.
The bind variables of the view object are not required.
I made a page with a search form (af:query) but I want that even I complete only one field (no1_prm or no2_prm) to receive the result for that parameter. Now I receive error that the filed is required.
How can I make :
- when I complete one value for the parameter to receive exact value for that parameter
- when I complete the two values for the parameters to receive all the numbers between the two parameters.
Thank you in advance.

I set only that condition : No between no1_prm and no2_prm with validation optional and ignore null values checked.
The all view object where clause is :
( ( NR BETWEEN :nr_prm1 AND :nr_prm2 ) OR ( :nr_prm1 IS NULL AND :nr_prm2 IS NULL ) )
I mention that in my page I must to have only : No label : input text for no1_prm - input text for no2_prm. If I complete only input text for no1_prm I receive the error for required field.
Thank you.

LOV view criteria missing in af:query field when AM pooling is disabled

Hi all,
Again, another strange behaviour with fields in af:query when AM pooling is disabled.
I have a field with a LOV in the af:query area. This LOV has a view criteria that involves a bind variable. In the VO, the view accessor for this LOV applies the view criteria and sets the bind variable. When AM pooling is disabled, double clicking a row or clicking the OK button in the LOV window removes the where clause defined by the view criteria. When activation occurs, the bind variable still exists but the framework doesn't know where to apply it...
Any help will be very appreciated,
Thanks
JDeveloper 11.1.1.3.0 with ADF BC
We've just realised that this behaviour occurs even when pooling is enabled. So this is becoming now a serious problem.
The scenario is as following: We have two LOVs in the search area (af:query). One of them is dependent on the other. Then, this second LOV has a view criteria and a bind variable representing the value selected for the first LOV. The query for the second LOV is filtered properly, but once a value has been selected and the LOV window dismissed, nothing is returned to the field.
We have observed that SecondLovViewImpl.executeQueryForCollection() method executes twice:
1. When LOV is opened: here, the bind variable is correctly setted.
2. When a row in the LOV table is selected: here, the bind variable is reset to null.
The log says (in Spanish):
<OracleSQLBuilderImpl><bindParamValue> [46062] Binding null of type 12 for "bindProgram"
<FacesCtrlLOVBinding$ListOfValuesModelImpl><_getRowFromSelectedRowKey> ADFv: No se ha encontrado ninguna fila para rowKey: [oracle.jbo.Key[P1 SP11 ]].
I would be very grateful if somebody asked me... even for saying "this is nonsense", "this is a known bug", "cascading LOVs are not supported by af:query", or anything else... If a code snippet is required, I'll put it as well.
Thanks in advance

Hi,
there are two bugs associated with bind variables in successors that I am aware of. One of them is supposed to be fixed in the next patch set, another one is still open. However, both problems were found with AM pooling enabled as well, so I don't know this is the same problem (though it sounds like). If you can, I suggest to create a reproducible testcase on one of the Oracle database schema, like HR or OE, and file a bug. If you don't have a time for or access to support, send the test case in a zip file (rename ".zip" to ".unzip") to the mail Id you find in my OTN profile. However, be aware that when I file the bug then it wont be visible for you, nor can it be escalated on your behalf. Anyway, at least it would get filed

Bug in View Criteria for EXISTS operator

Hello!
I have two VO:
DEP (ID, TITLE, STATUS)
EMP (ID, ID_DEP, NAME)
and viewlink DEP.ID <- EMP.ID_DEP
in DEP VO i create view criteria and add two items:
* DEP.STATUS <> 1000
* the EMPVO with EXISTS operator (and after that add condition EMP.NAME contain :nName (bind var))
start app, set "john" in search field, press button "search" and in debug console i found sql for searching in DEP:
SELECT *
FROM (SELECT DEP.ID,
DEP.TITLE,
FROM DEP DEP
where (DEP.STATUS is null OR DEP.STATUS <> 1000)) QRSLT
WHERE ((((EXISTS (SELECT 1
FROM EMP EMP
WHERE ((UPPER(EMP.NAME) LIKE
UPPER('%' || :nName || '%')))
AND (ID = EMP.ID_DEP))))))
in last row present error, must be:
AND (QRSLT.ID = EMP.ID_DEP))))))
coz if no "QRSLT", sql parser think what need compare EMP.ID and EMP.ID_DEP.
Present in JDeveloper 11.1.1.2.0, 11.1.1.3.0.

We have implemented our own ViewCriteriaAdater (derived from oracle.jbo.server.OracleSQLBuilderImpl) and some custom properties to handle this. Overwrite the getFormattedRHSCompareFragment to your needs.
Btw. I think this posting should go to the JDev forum.

Dynamic Region:VO with a view criteria does not filter data

Hi all,
I am using Jdeveloper 11.1.1.0
I have a page with two section: the first section contains a table, the second contains a region that changes depending on the row choosed in the table of the first table.
Starting from a VO a I have defined some view criterias and in my application module I have created some data control components based on that VO and those view criterias.
So, in my application module, I have a components for every view criteria defined in the VO.
In every fragments visualized in the dynamic region I have a table derived from a view object derived from view criterias defined before.
The problem is that in the fragment I always see all the data and not filtered data.
Instead, if I run my application module, in those view objects, I see the filtered data.
I have noted that (after dragging and dropping the component to the fragment) in the "Bindings" schede, in "Executable" editing myVOFilteredQuery, the field "Criteria" is empty.
Is this the problem? How have I to fill it?
Or the problem is another?
Thank you so much
Andrea

This issue is fixed.
Thanks and Regards

Using SYSDATE in Pre-Defined View Criteria ADF BC

I’m trying to setup a View Criteria to find records between two dates. So I create a View Criteria and Select my date field from the table and then choose the “Between” operator and then my operand is a Bind Variable. Then in my Bind variables I have SYSDATE and SYSDATE-7. So in my view.xml I have the following:
<Variable
Name="SystemDate"
Kind="viewcriteria"
Type="java.sql.Date">
<TransientExpression><![CDATA[SYSDATE]]></TransientExpression>
</Variable>
<Variable
Name="Bind_SystemDateMinusSeven"
Kind="viewcriteria"
Type="java.sql.Date">
<TransientExpression><![CDATA[SYSDATE-7]]></TransientExpression>
</Variable>
However, when I try to run this View Criteria (using on an af:query component), I get the following error.
Messages for this page are listed below.
Error
Unexpected exception caught: java.lang.reflect.UndeclaredThrowableException, msg=null
Error
Name SYSDATE not found in the given object: ViewRow [oracle.jbo.Key[877 ]
Does anyone know how to do this using ADF BC and View Criterias? I've tried making my bind variables Strings and this doesn't work either. I basically want a predefined query that finds records within a specific week given the system date. Any ideas on how to make this work? Thanks.

You can achieve SYSDATE in ADF BC View Criteria using IsSqlFragment="true".
Below is the VO source code snippet for the same.
<ViewCriteriaItemValue
            Name="ViewObjCriteria_ViewObjSubCriteria1_vcrow40_HireDate_vcval0"
            Value="sysdate-350" IsSqlFragment="true"/>
          <ViewCriteriaItemValue
            Name="ViewObjCriteria_ViewObjSubCriteria1_vcrow40_HireDate_vcval1"
            Value="sysdate" IsSqlFragment="true"/>
</ViewCriteriaItem>

ADF-View criteria

Hi all:
I'm working in Jdev TP3.
I do view criteria on the view and then I want to do search form with it.
The view has a transient column to checkbox but I don't know how insert on the view criteria because if I insert it
doesn't appear on the search form.
Can somebody help me?
Thanks in advance.

Thanks by reply Steve
The transient attibute is boolean. I did because I have string attribute and I need to show checkbox.
I add transient attribute to the view criteria and Query Execution Mode put "in memory " because it didn't leave put database.
When I dropped a view criteria, I used my custom view criteria which included the transient attribute.
Thanks in advance.

Is it even possible to dynamically apply view criteria in an ADF Web App?

This is one of those situations where something that should take an hour ends up taking days.
* I have a view.
* The view has Bind Variables associated with it.
* The view has View Criteria associated with it.
* Each of the View Criteria use different Bind Variables.
* I have a search criteria input page that receives from the user what will ultimately be used to set the bind variables.
* I have a search results page that uses the view to display a table.
* I have the code that dynamically sets view criteria and parameters. It is based on the following:
http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcadvvo.htm#BCGFHAGA
* This code works great, until the iterator associated with the table binding to the view is initialized. At that time, the view is reset to its defaults, and all of my code's doings are discarded. How do I know this? Because I have gone so far as to run my code that sets view criteria and binding variables dynamically in a phase event handler for the search results page in the render response phase. There is no other point at which to dynamically modify the view.
This is turning into a situation where it seems I will need 5 different views and 5 different pages in order to show a single set of query results. I cannot get dynamically applied view criteria to work in an ADF web app. Has anyone else done it? Can anyone relate to this? Are there any other suggestions before I conclude that it's not possible for this framework to handle this simple scenario?
Thanks

There must be a setting or something that I am still missing here. If I write code just like this and make sure it is executed, I still only see the results of my view executed without the view criteria applied using the default bind variable values that I supplied in the view object.
It's like the fact that I set the bind variables, the view criteria, and executed the view query programmatically is lost on the iterator -- it's like it never happened. What setting is used to ensure that the iterator uses the outcome of what I executed programmatically? There has to be a critical set or setting that I am missing.
Here is the iterator and search region definitions defined in the page def "executables" section:
<executables>
     <iterator Binds="CustomSearchView1" RangeSize="25"
              DataControl="AppModuleDataControl"
              id="CustomSearchView1Iterator"/>
    <searchRegion Binds="CustomSearchView1Iterator"
                  Customizer="oracle.jbo.uicli.binding.JUSearchBindingCustomizer"
                  id="CustomSearchView1Query"/>
    </executables>Here's the "tree" binding in the page def file:
<bindings>
   <tree IterBinding="CustomSearchView1Iterator" id="CustomSearchView1">
      <nodeDefinition DefName="Model.CustomSearchView" Name="CustomSearchView10">
        <AttrNames>
          <Item Value="CustomId"/>
          <Item Value="CustomProjectNumber"/>
          <Item Value="CustomName"/>
          <Item Value="CustomStatus"/>
          <Item Value="CustomStatusDate"/>
        </AttrNames>
      </nodeDefinition>
    </tree>
</bindings>In an effort to take page flow out of this mess, I had modified this to include the search criteria and search results on a single page. So, I now have a "Search" button. When the "Search" button is clicked, the action method does the following:
    public String searchActionListener ()
          // Get search criteria from select one choice and text input controls.
          AppModule appModule =
                ( AppModule ) Configuration.createRootApplicationModule (
                    "Model.AppModule",
                    "AppModuleLocal");
          appModule.customSearch( searchCriteria1,
                                               searchCriteria2,
                                               searchCriteria3 );
    }In my application module this translates to:
    public void customNoticeSearch ( String searchCriteria1, String searchCriteria2, String searchCriteria3)
       CustomSearchViewImpl searchViewImp =
           ( CustomSearchViewImpl ) this.getCustomSearchView1 ();
       searchViewImp.customExecuteQuery ( searchCriteria1, searchCriteria2, searchCriteria3);
    }Finally, in my custom view object implementation code:
    public void customExecuteQuery ( String searchCriteria1, String searchCriteria2, String searchCriteria3 )
        // Set-up the parameters that are part of the core query.
        this.setp_searchCriteria1( searchCriteria1);
        this.setp_searchCriteria2( searchCriteria2);
        if ( searchCriteria3 != null )
            ViewCriteriaManager vcm = this.getViewCriteriaManager();
            ViewCriteria vc = vcm.getViewCriteria ( "WithLastCriteria" );
            this.setp_searchCriteria3( new Number ( searchCriteria3 ) );
            this.applyViewCriteria( vc );
        System.out.println ("This is fun.");
        this.executeQuery();
    }This code executes, but the results table is empty, and I know that there are results, because I can execute use execute with params to execute the base query and get the correct results back.
Thanks for taking a look at this.

Bizarre behavior of a View Criteria for a View Object

Hey,
I remarked quite a bizarre behavior of the View criteria that I created for my view object, using bind variables.
lets say I have the generated query in the View object:
SELECT Paquet.ID,
Paquet.WEIGHT,
Paquet.VALUE,
Paquet.ORIGIN,
Paquet.DESTINATION
FROM PAQUET Paquet
I want to use the executeWithParams with bind variables for this View object.
I create a bind variable:p_o
I create the View Criteria vith the visual editor that generates an additional view clause:
( ( ( Paquet.ORIGIN LIKE ('%' || :p_o || '%') ) OR ( :p_o IS NULL ) ) )
test query works and explain plan as well.
Now, when I execute the view object on a page with the bind variable properly set, I get the error: java.sql.SQLException: Attempt to set a parameter name that does not occur in the SQL: p_o
Then I copy the where clause generated by view criteria visual edito directly to the query and delete the View Criteria, and it ALL WORKS FINE
If has to work like that, then what is the View Criteria useful for? I still think that there is a problem.
Thanks!
Taavi

Hi,
ViewCriterias are not accessed with ExecuteWith Params. For this the bind variable needs to be in the where clause. Named ViewCriterias are listed separately in the DC list
