How to populate bind variable in view objects where clause in ADF faces

I've got a page with 2 input items.
The user manually enters the first value.
On the second input item I have created a LOV for the item which opens in a popup. How do I restrict the data returned in the LOV using the value entered in the first input item. I have created a bind variable and have included it in the where clause for the view object but how do I populated it.

Here is an example:
Using the HR schema with the EMPLOYEES and DEPARTMENTS tables.
Example is using ADF BC and created an EMPLOYEES entity with an updateable view object for page,
and created a DEPARTMENTS view as a lookup
(SQL: select department_id, department_name from departments where department_name = :DeptName)
1: add method to the backing bean to filter the LOV
public void getTextValueToFilterLOV(ValueChangeEvent valueChangeEvent) {
Object value_from_form = valueChangeEvent.getNewValue();
FacesContext fctx = FacesContext.getCurrentInstance();
Application fapp = fctx.getApplication();
JUFormBinding formBinding = (JUFormBinding)fapp.createValueBinding("#{bindings}").getValue(fctx);
DCIteratorBinding dcBinding = (DCIteratorBinding)formBinding.get("DeptLOVIterator");
ViewObject vo = dcBinding.getViewObject();
vo.setNamedWhereClauseParam("DeptName",value_from_form);
vo.executeQuery();
2. add valueChangeListener to the inputText on the page with an id and autoSubmit="true"
<af:inputText value="#{bindings.LastName.inputValue}" label="#{bindings.LastName.label}" binding="#{backing_DeptForm.inputText3}"
id="inputText3"
autoSubmit="true"
valueChangeListener="#{backing_DeptForm.getTextValueToFilterLOV}">
</af:inputText>
3. reference the LOV with the id name on the partialTriggers property
<af:selectOneChoice value="#{bindings.EmployeesUpdView1DepartmentId.inputValue}"
label="#{bindings.EmployeesUpdView1DepartmentId.label}" binding="#{backing_DeptForm.selectOneChoice1}"
id="selectOneChoice1"
partialTriggers="inputText3">
<f:selectItems value="#{bindings.EmployeesUpdView1DepartmentId.items}"
binding="#{backing_DeptForm.selectItems1}"
id="selectItems1"/>
</af:selectOneChoice>
Summary:
When you entered a text (LastName), that value is passed into the backing bean method.
The Bean method code will find the LOV Iterator and put the value into the bind variable.
Cheers,
Jim

Setting bind variables in view objects for LOV

ADF 11.1.1.1.0
I have two application modules - amCodeTable (contains the code tables) and amLOV (contains the list of values)
In amLOV I have a VO aListOfValuesVo (not based on an entity) that runs a query Select * from aTable where userNr = :pBindVar
In amCodeTable I have a VO aMainTableVo based on an EO, This VO has a field (aLOVField) which has a LOV defined on it and uses the
aListOfValuesVo.
I've hardcoded the bind parameter to its corresponding value and everything works as expected, list of values from
aListOfValuesVo available on the aLOVField in aMainTableVo.
I now need to set the bind parameter by code.
What I have tried to do is override the execute query of the aListOfValuesVo in the aListOfValuesVoImpl.java
    @Override
    public void executeQuery() {
       setNamedWhereClauseParam("pBindVar","32");
       super.executeQuery();
    }If I test the amLOV application module the query returns the correct values.
If I test the amCodeTable the list of values on the aLOVField in the view aMainTableVo is empty.
I've added a breakpoint to the executeQuery() method but it would seem that the method is not called.
How are bind parameters for list of values set ?

The parameter is being binded to the lovUserBranch but the LOV is using the lovUserBranch_0 which has a bind value of null
Anybody got any idea as to what is happening ?

How to declare a bind variable with 'date' data type in command prompt?

how to declare a bind variable with 'date' data type in command prompt?
sql>variable q date;
when i execute it show list of datatypes

Hi,
As Lokanath said, there are no DATE bind variables.
You can use a VARCHAR2 bind variable, and convert it to a DATE in your SQL statment.
If you're using SQL*Plus, consider a substitution variable. It won't be as efficient as a bind variable, but it will be as convenient.
For example:
DEFINE first_entrry_date = "DATE '2010-06-20''
SELECT   ...
WHERE   entry_date >= &first_entry_date
{code}

How to properly set bind variables

Dear All,
I am currently confused about how to properly set my Bind Variables
I have this view using HR standard schema
Select *
from Employees
where EMPLOYEE_ID = :EMP_IDI somehow see three options on how to use this bind variable in an application module.
Option 1:
ViewObjectImpl view = this.getEmployeesView();
VariableValueManager vm = view.ensureVariableManager();
vm.setVariableValue("EMP_ID", value);
view.executeQuery();Option 2:
ViewObjectImpl view = this.getEmployeesView();
view.setNamedWhereClauseParam("EMP_ID", value);
view.executeQuery();Option 3:
EmployeeViewImpl empView =this.getEmployeesView();
RowSetIterator it = empView.createRowSetIterator(null);
empView.setEmployeeId(value);
empView.executeQuery();Question is which is which and what should I use?
JDEV 11G PS3

I use is this
DCIteratorBinding iteratorStatus = Util.getIterator("NameIterator");
operationBinding.execute();
Util is reserved in a class.
public static DCIteratorBinding getIterator(String iteratorName){
return getDCBindings().findIteratorBinding(iteratorName);
}

How to identify the bind variable peeking problem?

How to identify the bind variable peeking problem whether my db hitting or not and how to resolve it?
currently we are doing the dbms_stat of application schema's with gather auto option and i hope this option we take the histogram stats also. Is there any option to improve it and its highly transactions oltp env of 11g.

What is your exact 4 digits Oracle version ?
Bind peeking issues are supposed to be solved with adaptative cursor sharing in 11.1 and 11.2:
11.1 http://download.oracle.com/docs/cd/B28359_01/server.111/b28274/optimops.htm#sthref919.
11.2 http://download.oracle.com/docs/cd/E11882_01/server.112/e16638/optimops.htm#PFGRF94588
which says also:
>
Adaptive cursor sharing is enabled for the database by default and cannot be disabled. Note that adaptive cursor sharing does not apply to SQL statements containing more than 14 bind variables.

it Shows Errors as

could anyone tell what could be the wrong. Do we need to set bind variable in view link Explicitly? or any other alternative.
Its very Urgent.

Hi,
I have faced similar problem some time ago. I could not find any solution except removing bind parameters in where clause. I tried to change binding style but it also didn't work. I think the problem is caused by view link's where clause.

Bind variables in views

I am having some performance issues using bind variables in views (Oracle 7.3.4). When I execute the view using '' values the view executes the expected execution plan. When I execute the view using bind variables the execution plan changes to something undesireable. I believe this to be a static execution plan in the case of using bind variables. I have updated all tables referenced by the view and compiled the view; but, the execution plan when using the bind variables does not change. Can you give me some advice on finding out why the execution plan in the case of using bind variables does not change based on the new set of statistics and being re-compiled.

even if you use a literal isn't that automatically
changed into a bind variable during at compile time?That would be the case when your have CURSOR_SHARING = FORCE. The default should be EXACT.
SQL> show parameter cursor_sharing
NAME TYPE VALUE
cursor_sharing string EXACT
SQL>Actually, since you have the constants in the view, and if everyone uses the view, they share the same shared cursor (since the constants are never changing across each use).
If you supplement the view with additional WHERE conditions (when using the view):
SELECT <columns> FROM your_view WHERE <additional_conditions> ;
Ten you might want to look into using bind variables for values used in such additional conditions.

Dynamically change the Binding of a view object

I want to reuse a panel several times in my application. The VO has one bind parameter (:1). The same panel should be reused several times with different bind variables.
I found a technical note concerning this issue called: How to Dynamically Change the binding of a View Object to a JClient Panel. This works for JDeveloper 9i but not for JDeveloper 19g. Does anybody know how to dynamically change the binding in JDeveloper 10g

You may use bindRowSetIterator() and pass in a custom fetched ViewObject or a RowSetIterator to the iterator binding that is displayed in your panel.

How to pass the bind variable value to the sql statement of the LOV

Hi,
I am using Forms 10g builder.
I have a text item which will be populated by a LOV when i press a button, but i have a bind variable in the SQL statement of the LOV. That bind variable should be replaced by a value which is derived from a radio group in the same data block.
For Ex: ( )radio1 ( )radio2
before i click on the push button, I'll select one of the radio button above,so my question is how to assign this radio group value to the bind variable in the sql statement in the LOV?
Pl any hint is appreciated!
Thanks
Reddy

The variable can be taken into account in the SELECT order contained in the Record Group used by the LOV.
e.g. Select ... From ... Where column = :block.radio_group ...Francois

How to querie with bind variable in findMode?

Hallo,
is it possible to use a querie with bind variable in findMode? And when how is it possible to initialize the bind variable?
Any help is appreciated.

Hi,
bind variables can be linked from teh ADF binding to e.g. a managed bean, the sessionScope or other binding attributes via EL. So when you go into findMode and execute the query, the EL will grab the bindVariable values automatically.
