ADF View Accessor Validation with Bind Variable

Hi
I need to solve the following requirement using a view accessors and bind variables;
1. User can select a value for a attribute from LOV which is unfiltered.
2. User can manually edit code into the same attribute as in 1 above, which needs to be validated.
As the data set for the attribute is large, I need to be able to validate 2 using a query with a where clause.
My approach has been;
1. I have a view object for the source lookup table, ProductVO.
2. I have created a view criteria on ProductVO that accepts a bind variable, pProductCode.
3. On my OrderEO I have a attribute, productCode.
4. I create a new view accesor on the OrderEO using the view criteria created in point 2.
5. I have lft the bind variable parameter blank, as I need to be able to dynamically pass a product code at run time.
6. On my OrderVO for the productCode attribute, I have create a LOV, based on the ProductVO. This will ensure that the user can view and search all products if needed.
What I am not getting working;
1. How can I pass the attribute value to the view accessor at runtime when the value is manually captured.
2. Ensure that if a value is selected from the LOV, that the view accessor validation does not get invoked.
What I have tried to solve point 1;
1. I created a validator on the productCode attribute on the OrderEO as a list validator using the view accessor as my list. I am not sure how to get the bind variable populated. Leaving out the bind variable, I assume, would cause the value to be validated against all my products.
2. I then tried using a method validator and passing in the productCode value and querying the view accessor.
3. I have not yet tried using Key Exists, is this maybe the missing link/trick?
All help will be considered a early christmas gift!!

Hi
I have found that when using validation type Key Exists and the VO is in the local application, then the bind variable is available in the Create Validation wizard. When I try and create a validator on a VO that is core to all my applications, then I put that VO into an ADF library, the bind variable parameter is not available for mapping to my entity object attribute, even though I can select the VO to create a view accessor from the ADF library.
Possible bug?

Label of attribute when used as View Criteria item with Bind Variable

I've a VO attribute used in a named search with this requirement:
The attribute provides has an optional View Criteria item that has a bind variable operand. The bind variable is in the WHERE clause. The attribute has an LOV. The choice list for the specified View Criteria item should display the label "Effective Release". However, in all other contexts, including the search results table and the dropdowns the user can optionally add in an advanced search, the label displayed for the attribute must say "Release".
In other words, the default label for the attribute should be "Release" in all but one context - which is that when the dropdown list for the viewCriteria item using the bind variable is displayed, the label should say "Effective Release".
Note that if the user moves to Advanced Search and selects adds the attribute as a search criteria, this latter usage should be labeled as "Release". (in this case, in other words, the dropdown that displays by default and has the bind variable operand is labelled "Effective Release", the one the user added in advance search is labelled "Release")
here is the View Criteria item source xml:
      <ViewCriteriaItem
        Name="ReleaseId1"
        ViewAttribute="ReleaseId1"
        Operator="="
        Conjunction="AND"
        Value=":v_ReleaseId"
        GenerateIsNullClauseForBindVars="false"
        ValidateBindVars="true"
        IsBindVarValue="true"
        Required="Required"/>I've experimented by putting "Effective Release" as the label for the bind variable as below. However, ADF does not use that value to display, it defers to the attribute value:
<Variable
    Name="v_ReleaseId"
    Kind="viewcriteria"
    Type="oracle.jbo.domain.Number">
    <Properties>
      <SchemaBasedProperties>
        <LABEL
          ResId="EFFECTIVE_RELEASE_LOV"/>
      </SchemaBasedProperties>
    </Properties>
</Variable>The reason for the requirement, if it matters, is that the View Criteria item with the bind variable ("Effective Release" queries a range of values using the analytic function rank(); the bind variable is in the WHERE clause. Otherwise, the dropdown that can be added in advanced search ("Release") looks for exact matches on the attribute value. So since the search functionality is different, the label should be different.
Am using 11g.
Thanks for your help.

ADF jdev10: SQL TRUNC with bind variable in sql statement in VO

Hi,
In VO in where clause:
TRUNC(ServiceRequest.REQUEST_DATE) > :MyDate works fine!
But TRUNC(ServiceRequest.REQUEST_DATE) > TRUNC(:MyDate) doesn't work!
"SQL Query Error Message: ORA-00932: inconsistient datatypes: expected DATE got NUMBER"
How to use TRUNC function for a bind variable?

Basementjack,
Any of these solutions that you are doing have possible performance implications in the database side, as you are applying a function to a database column; this is generally going to preclude the use of an index.
Assuming that you are trying to find service requests that were before the date that is being passed in in the bind variable, and assuming that both the bind variable and service request date can have time components, you could try:
ServiceRequest.REQUEST_DATE <= TO_DATE(trunc(:MyDate) - 1/86400)Does this do what you want?

How to use ApplicationModuleImpl.createViewObject for VO with bind variable

I need to implement a AM method to create VO instance from a generic VODef with bind variables.
The createViewObject() will trigger the executeQuery of the VO before I can set up the bind variables for the query.
What is the proper way to create view object instance with bind variables?

I am using JDeveloper 11.1.1.2.
I have a ViewObjectA declared with some bind variables which determine what business data to be retrieved at runtime via a service method of the ApplicationModule.
As the ViewObjectA is only referenced internally within ApplicationModule and I need more than one instance of the ViewObjectA for different conditions at runtime,
I use ApplicationModuleImpl.createViewObject() to create an instance of ViewObjectA instead of adding ViewObjectA to the data model of the ApplicationModule.
Currently, when the ViewObjectA is instantiated, it also trigger an executeQuery() which will not retrieve correct data until I set up the bind variables.
However, the createViewObject() method doesn't let me pass in the values of the binding variables.
Currenlty, I just call the createViewObject() and then set the binding variables values and call executeQuery() again.
Just checking if there is a better way to do so...

Detail view with bind variable. TreeTable not showing all detail result.

I’m having trouble with treeTable using detail view with bind variables and where clause defined in VO definition.
Both, master and detail view objects, base on the same entity and have the same condition in where clause. The view objects also have bind variables, which are set in prepareRowSetForQuery() method.
Again, these are two different views, that get different result, based on value of one of the bind variable.
When I show results in two different tables on jsf page, where master table has "RowSelection" set on "single", all results are displayed in detail table.
But when I use treeTable, only the first result of the detail is shown.

I tested it in applicationModule and it works, but i think that's the same as two tables on a jsf page.
This is the order in which overridden methods are called in ADF BC or two tables on jsf page
when clicking on row in master table.
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object; -> print of the object2[] parameter in executeQueryForCollection
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035313 -> viewLink parameter value
getEstimatedRowCount_Detail
count: 2
getEstimatedRowCount_Detail
count: 2 And when i click on "expand node" in tree table:
getEstimatedRowCount_Root
count: 2
PrepareRowSetForQuery_Detail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035321
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035313
getEstimatedRowCount_Root
count: 2
getEstimatedRowCount_Root
count: 2
getEstimatedRowCount_Root
count: 2
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035313
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035321
getEstimatedRowCount_Root
count: 2
getEstimatedRowCount_Root
count: 2Values of user parameters are OK. Is there another method that i should override?
I also noticed, that if detail view doesn't have user bind variables, the tree works fine and is shown even in ADF BC (aplication module).
I guess we loose a tree, when using bind variables in detail view object.
Is there a way around it?

ADF Groovy Expression with bind variable and ResourceBundle

Now I have ViewObject which have WHERE clause with bind variable.
This bind variable is for language. Within bind variable I can change Value Type to Expression and into Value: I put +(ResourceBundle.getBundle("model.ModelBundle")).getString("language")+.
Now if I run Oracle Business Component Browser (on AppModule) this works. In my ModelBundle.properties there is language=1 name-value pair. And with different locale I have different language number.
Now if I put that ViewObject on one JSF, this bind variable expression does not work any more. Error:
*oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.util.MissingResourceException, msg=Can't find bundle for base name model.ModelBundle, locale my_locale*
Any ideas?

Zmeda

The most wierd thing is that, if I make ViewObjectImpl and insert this method
public String getLanguage() {
return (ResourceBundle.getBundle("model.ModelBundle")).getString("language");
and call it in Bind Variable Expression Value: viewObject.getLanguage()
IT WORKS!
But why with groovy expression it does not work?

LOV(af:selectOneChoice) with bind variable in af:table

Hi All,
I have a table where a column is defined as dropdown(af:selectOneChoice). The query for selectOneChoice has a bind variable which needs to be set as a value from the base view Object corresponding row.
Suppose a table Employee
EmpId EmpName EmpType Authorization
101 John Temp No
The above table is created as af:table and 'Authorization' is implemented as dropdown(af:selectOneChoice) . The selectOneChoice has a query(AuthorizationLovVVO) with bind variable . For each row of af:table(EmployeeVO) , af:selectOneChoice query(AuthorizationLovVVO) requires
the corresponding row(EmployeeVO) 'EmpType' to be set as value of bind variable.
Can you please suggest how can we achieve this functionality.

I have checked the following post where it has been suggested to access the the current row value as groovy expression.
groovy for bind variable
Suppose my AM name is 'TestAM' , i have tried the below expressions for value of bind variable but it does not work :
1) adf.object.TestAM.findViewObject('EmployeeVO1').currentRow.EmpType
2) adf.object.TestAMDataControl.findViewObject('EmployeeVO1').currentRow.EmpType
None of the above expressions work and i get the error while running the page as 'Variable NotesAM is not recognized.' / 'Variable NotesAMDataControl is not recognized.' .
Can you please suggest if we can achieve the functionality using this approach . Also let me know if i am missing something in the above expression.

Report Performance with Bind Variable

Getting some very odd behaviour with a report in APEX v 3.2.1.00.10
I have a complex query that takes 5 seconds to return via TOAD, but takes from 5 to 10 minutes in an APEX report.
I've narrowed it down to one particular bind. If I hard code the date in it returns in 6 seconds, but if I let the date be passed in from a parameter it takes 5+ minutes again.
Relevant part of the query (an inline view) is:
,(select rglr_lect lect
,sum(tpm) mtr_tpm
,sum(enrols) mtr_enrols
from ops_dash_meetings_report
where meet_ev_date between to_date(:P35_END_DATE,'DD/MM/YYYY') - 363 and to_date(:P35_END_DATE,'DD/MM/YYYY')
group by rglr_lect) RPV
I've tried replacing the "to_date(:P35_END_DATE,'DD/MM/YYYY') - 363" with another item which is populated with the date required (and verified by checking session state). If I replace the :P35_END_DATE with an actual date the performance is fine again.
The weird thing is that a trace file shows me exactly the same Explain Plan as the TOAD Explain where it runs in 5 seconds.
Another odd thing is that another page in my application has the same inline view and doesn't hit the performance problem.
The trace file did show some control characters (circumflex M) after each line of this report's query where these weren't anywhere else on the trace queries. I wondered if there was some sort of corruption in the source?
No problems due to pagination as the result set is only 31 records and all being displayed.
Really stumped here. Any advice or pointers would be most welcome.
Jon.

Don't worry about the Time column, the cost and cardinality are more important to see whther the CBO is making different decisions for whatever reason.
Remember that the explain plan shows the expected execution plan and a trace shows the actual execution plan. So what you want to do is compare the query with bind variables from an APEX page trace to a trace from TOAD (or sqlplus or whatever). You can do this outside APEX like this...
ALTER SESSION SET EVENTS '10046 trace name context forever, level 1';Enter and run your SQL statement...;
ALTER SESSION SET sql_trace=FALSE;This will create a a trace file in the directory returned by...
SELECT value FROM v$parameter WHERE name = 'user_dump_dest' Which you can use tkprof to format.
I am assuming that your not going over DB links or anything else slightly unusual?
Cheers

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.

Where clause with Bind Variable in ViewObject

As per recomendations from Jdev team they say that using Bind varialbles in where clause will improve the performance (Option 1) But it is causing us to create more view objects.
Example : Lets say we have a View Object EmpVO
Option 1:
ViewObject vo=context.getViewObject("EmpVO");
vo.setWhereClause("EMPNO=?");
vo.setWhereClauseParam(0,st);
(or)
Option 2:
vo.setWhereClause("EMPNO="+st);
If we want to use same View Object "EmpVO" in another Action Class
ViewObject vo1=context.getViewObject("EmpVO");
vo1.setWhereClause("DEPTNO=?");
vo1.setWhereClauseParam(0,str);
It this case it throws an error saying BIND VARIABLE already exits. So we have to make another View Object.
Where as if we did not use bind variable but used Option 2 approach the same view object can be used in multiple pages.(at the expense of performance as per Jdev team)
Are we doing something wrong here or are there other ways to use the same view object when using bind variable in where clause.
Thanks

I haven't been using BC4J for a while, but I seem to recall that the recommendations are that you don't set the where clause at runtime: You're supposed to define your view with the bind parameter already in it.
So you'd probably define an EmpsForEmpNoVO and type "EMPNO = ?" in the where box. (There are other ways of finding a single row/entity and one of those may well be more efficient. Perhaps a better example of where you might want a view of employees is WHERE DEPTNO = ?.)
IIRC, all instances of a particular type of view share the same definition, so you have to be careful if you alter that at runtime. However, I think everything's set up so that you can have many different (and separate) resultsets for a single view (instance) - meaning that it's possible to "run" a view for (e.g.) two different ids. (It's definitely possible to create two different instances of a view from its definition - and the resultsets will definitely be separate then. I think there's a "create" method on the application module; I remember that "find..." always returns the same instance of the view.)
Hope that's a push in the right direction (since no-one else had replied - and I hope not too much has changed since 9.0.3)....
Mike.

BC4J bug with "bind variables" JBO-27122 ORA-01008

I think we are found a BUG using BC4J with bind variables in a view object.
If the bind variable appear in the WHERE condition two or more times at
the beginning of the query the above error occur.
oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation. Statement:
SELECT Emp.EMPNO,Emp.ENAME,Emp.JOB,Emp.MGR,Emp.HIREDATE,Emp.SAL,Emp.COMM, Emp.DEPTNO
FROM SCOTT.EMP Emp
WHERE :1 <=10000 and :1 <= sal and :2=20
java.sql.SQLException: ORA-01008: not all variables bound
Otherwise if bind variable apper two or more times, but not together
like this sample:
WHERE :1 <=10000 and :2=20 and :1 <= sal
the error not occur.
We prove this with:
JDeveloper 9.0.5.2 (build 1618)Business Components Version 9.0.5.16.0
JDeveloper 9.0.5.0 (build 1375)Business Components Version 9.0.5.13.52
I looking for a patch! or acceptable workaround.
Tx for your help!

/* the cliente app */
ApplicationModule am = Configuration.createRootApplicationModule("business_tier.AppModule","AppModuleLocal");
ViewObject vo = am.findViewObject("EmpView");
vo.setWhereClauseParam(0,"100");
vo.setWhereClauseParam(1,"20");
Row emp = vo.first();

This is a known bug (1326006). The workaround is to use:
vo.setWhereClauseParam(0,"100");
vo.setWhereClauseParam(1,"20");
vo.setWhereClauseParam(2,"20");
Hope this helps,

Af:query with bind variables and Saved Search

I have a VO and view criteria(VC).
VC has a criteria item ObsoleteDate with range specified as bindVariables "dateFrm" and "dateTo" I dragged & dropped the named criteria as af:Query with table. Table toolbar has 2 buttons in which I set & clear the bind variables. Data is fetched as per as expected based on the VC & bind variables.
The problem is,
If I save my search with bind variables set and swap between the saved searches , all works fine. But the moment I clear bind variables & swap between searches.. "dateFrm" is populated and "dateTo" is null and I get an Exception oracle.jbo.AttrValException: JBO-27035: Attribute Obsolete Date: is required.
Why is this happening?? Saved search is supposed to save the VC with all the bind values set while saving and clearing bind variables shouldn't affect the saved search, right?? Or I have understood it wrong?
I am using JDeveloper 11.1.2.3.0
Thanks

I use Release 11.2.0.2.3This specific scenario is very much an exception to the rule - and you need to back your statement up with execution plans of the SQL with bind variables and with literals, and run stats that show the difference between these two execution plans.

Query with bind variable, how can use it in managed bean ?

Hi
I create query with bind variable (BindControlTextValue), this query return description of value that i set in BindControlTextValue variable, how can i use this query in managed bean? I need to set this value in String parameter in managed bean.
Thanks

Put the query in a VO and execute it the usual way.
If you need to, you can write a parameterized method in VOImpl that executes the VO query with the parameter and then call that method from the UI (as a methodAction binding) either through the managed bean or via a direct button click on the page.

SLOW report performance with bind variable

Environment: 11.1.0.7.2, Apex 4.01.
I've got a simplified report page where the report runs slowly compared to running the same query in sqldeveloper. The report region is based on a pl/sql function returning a query. If I use a bind variable in the query inside apex it takes 13 seconds to run, and if I hard code a string it takes only a few hundredths of a second. The query returns one row from a table which has 1.6 million rows. Statistics are up-to-date and the columns in the joins and where clause are indexed.
I've run traces using p_trace=YES from Apex for both the bind variable and hard coded strings. They are below.
The sqldeveloper explain plan is identical to the bind variable plan from the trace, yet the query runs in 0.0x seconds in sqldeveloper.
What is it about bind variable syntax in Apex that is causing the bad execution plan? Apex Bug? 11g bug? Ideas?

Patrick, interesting insight. Thank you.
The optimizer must be peeking at my bind variables with it's eyes closed. I'm the only one testing and I've never passed %anything as a bind value. :)
Here's what I've learned since my last post:
I don't think that sqldeveloper is actually using the explain plan it says it is. When I run explain plan in sqldeveloper (with a bind variable) it shows me the exact same plan as Apex with a bind variable. However, when I run autotrace in sqldeveloper, it takes a path that matches the hard coded values, and returns results in half a second. That autotrace run is consistent with actually running the query outside of autotrace. So, I think either sqldeveloper isn't really using bind variables, OR it is using them in some other way that Apex does not, or maybe optimizer peeking works in sqldeveloper?
Using optimizer hints to tweak the plan helps. I've tried both /*+ FIRST_ROWS */ and /*+ index(ps pk_persons) */ and both drop the query to about a second. However, I'm loath to use hints because of the very dynamic nature of the query (and Tom Kyte doesn't like them either). The hints may end up hurting other variations on the query.
I also tested the query by wrapping it in a select count(1) from ([long query]) and testing the performance in sqldeveloper and in Apex. The performance in that case is identical with both bind variables and hard coded variables for both Apex and SqlDeveloper. That to me was very interesting and I went so far as to set up two bind variable report regions on the same page. One region wrapped the long query with select count(1) from (...) and the other didn't. The wrapped query ran in 0.01 seconds, the unwrapped took 15ish seconds with no other optimizations. Very strange.
To get performance up to acceptable levels I have changed my function returning query to:
1) Set the equality operator to "=" for values without wildcards and "like" for user input with wildcards. This makes a HUGE difference IF no wildcard is used.
2) Insert a /*+ FIRST_ROWS */ hint when users chose the column that requires the sub-query. This obviously changes the optimizer's plan and improves query speed from 15 seconds to 1.5 seconds even with wildcards.
I will NOT be hard coding any user supplied values in the query string. As you can probably tell by the query, this is an application where sql injection would be very bad.
Jeff, regarding your question about "like '%' || :P71_SEARCH_SOURCE1 || '%'". I've found that putting wildcards around values, particularly at the beginning will negate any indexing on the column in question and slows performance even more.
I'm still left wondering if there isn't something in Apex that is breaking the optimizer "peeking" that Patrick describes. Perhaps something in the way it switches contexts from apex_public_user to the workspace schema?
