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?

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?

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

View with Bind Variable and ADF table

Hi all,
Please note what i have noticed. I created a view with a bind parameter, overriden the prepareSession of my Application Module to set the bind parameter and execute the query. I then created a simple jsf page and included the view as an adf read-only table. When i run the page, the prepareSession is called, sets the bind parameter, however the selected record of the table is always the second record (Not the first record).
This behaviour can be reproduced with the HR schema. Please follow the below instructions for reproducing the problem.
1. Create a Fusion Web Application (ADF).
2. Create business components from tables.
3. Create a new connection with the HR schema.
4. Import the Departments table as an entity and then click finish.
5. Create a view based on the Departments entity.
6. Modify the Query to include a where clause (where DDepartmentsEO.DEPARTMENT_NAME LIKE :BindParam)
7. Provide an order by clause (DepartmentsEO.DEPARTMENT_ID DESC)
8. Creata a bind variable named "BindParam" of type string.
9. Create an Application Module and include the view object.
10. Open the Application Module Class and override the prepareSession method
11. include the following code after super.prepareSession(session):
ViewObject myView = this.getDepartments1();
myView.setNamedWhereClauseParam("BindParam", "%");
myView.executeQuery();
12. Create a jsf page
13. Drag the view object on the page as an adf read-only table, selecting the Row Selection, Sorting and Filtering
14. Run the page.
You will see that instead of the first record being selected, the second record in the table is selected.
Can anyone please help me?
Thank you

First of all i would like to thank you for replying to my thread.
Secondly, i would like to inform you that the example that i have provided is just for REPRODUCTION purposes.
The real scenario has to do with setting the where clause with the authenticated user so that the view will query for data only associated with the authenticated user.
The only way to overcome this behaviour is to include a view action (namedWhereClause in the page definition)
However, this is not how i want to implement this. This was working properly in 10g

Query With Bind Variables and %

Hi,
Quick question. I am using ADF BC on Jdev 11 with a MySQL Database.
I've used Bind Variables in the past (I have to use a Question Mark [?]) and have had no problem.
Now I want to do something like this in my where clause:
SELECT TempTable.ABC FROM TempTable
WHERE ABC LIKE ?%
When I try and create the View Object with that query it is complaining about the %.
Am I required to append the % in my bind variable? Any examples I have seen of this, people are doing something like :p_id = 'Jo%'

Try
like ? || '%'

How to access a request scope value in groovy expression of bind variable?

I need to filter the VO query based on the username.Following is what I am doing:
<af:commandButton text="#{translationviewBundle['LoginPage.LOGIN']}"
id="cbLogin" partialSubmit="true"
action="validate">
<af:setPropertyListener to="#{requestScope.userName}"
type="action"
from="#{backingBeanScope.LoginUserBb._username}"/>
</af:commandButton>
In the bind variable(pUserName) I set the value as : adf.context.current.requestScope.get('userName')
and the VO query :
SELECT DISTINCT
LANGUAGES.NAME,
LANGUAGES.ISO_CODE LANGUAGE_CODE
FROM
LANGUAGES LANGUAGES, USER_LANGUAGES USER_LANGUAGES
WHERE LANGUAGES.NAME <> 'English'
AND LANGUAGES.LANGUAGE_CODE = USER_LANGUAGES.LANGUAGE_CODE
AND USER_LANGUAGES.USER_ID = :pUserName
ORDER BY NAME
I get the following error: "Missing IN and OUT parameter at the index 1" and the query returns nothing.
Any suggestions pls?
Thanks,
Swathi Patnam

Your ADF BC layer shouldn't depend on a specific view layer, the best practice in such a case is to have an AM service method exposed to the client and have it accept a parameter.
Something like this:

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?

Problem with Bind Variable in 11.2

Hi
I have a slow statement with bind Variables. With literals it works fine. Is there a way to replace the bind by literal in advanced ? I use Release 11.2.0.2.3
Thank you

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.

RESTful service and BLOB with bind variable

Hi,
Has anyone successfully created a RESTful service with bind variable to retrieve a BLOB field and render it in an Apex app? I can create RESTful web service and render BLOB field for a record with no bind variable (single row). As soon as I add bind variable my RESTful service fails -- I get 404 Error. Without bind variable it renders both in TEST tool of Workspace and direct URL. As soon as I add a bind variable it fails either way. I have reported this in an SR to Oracle support, but thought I would post here too.
I would also like to retrieve the photo into an Apex application. Any hints would be appreciated.
Thanks,
Pat

Hi Fateh -
Good question. You would identify the source type as a Media Resource, and use an SQL statement with the primary key and the BLOB column. When you use Media Resource, you are essentially telling your Database Cloud Service not to marshall the data, just to send it - which is exactly what you are looking for.
With this implementation, you would have to have a separate SQL call for each BLOB retrieval. However, you might be able to use a PL/SQL block as the end point for the RESTful Service and take care of multiple BLOB processing in the block.
Hope this helps.

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?

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.

Problem with Bind Variable not updatable.

Hi all,
I'm using Jdev 11.1.2.3.0. In my VO, I created a Bind Variable and set it NOT UPDATABLE. Then I created a View Criteria with some other Bind Variables.
I use this View Criteria in a search page, but at runtime I see also an inpunt text for the variable that is set NOT UPDATABLE and I can change its value.
Of course if I try to change the value and I do the search, I get an error.
This is the VO source:
<Variable
Name="UlssVar"
Kind="where"
Type="java.lang.String"
IsUpdateable="false">
<TransientExpression><![CDATA[adf.context.current.sessionScope.get('ulss')]]></TransientExpression>
</Variable>
Is it a ADF bug?
Thank in advance.

Hi,
try selecting the bind variable and open the Property Inspector, under UI Hints, set the "Display Hint" to hide. This should hide it (No bug for this reason)

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.

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
Ben

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?
