Reset hidden formfields with bind on?

I have a form with grid and a form with fields that are bound
to the grid. Two fields are cfinput=text and one, the ID value is
cfinput=hidden:
<cfinput type="Hidden" name="ID" bindonload="false"
bind="{grid.ID}" />
<cfinput type="text" name="Label" bindonload="false"
bind="{grid.Label}"/>
<cfinput type="text" name="Desc" bindonload="false" >
<cfinput type="reset" name="reset" value="New">
<cfinput type="submit" name="submit" value="Save">
The reset button clears the text cfinputs but does not affect
the hidden one. Is there a way to clear the hidden field, since I
want to use the Save button to do both insert a new record or
update existing one, based on ID passed through the hidden field:
if it is empty, do this, otherwise do that.
On a side note, somehow bindonload has no affect on the forms
fields. The first value from the grin loads no matter if I use
bindonload=false or not at all.

$ ls -ldO@ /private
drwxr-xr-x 6 root wheel - 204 Dec 7 10:24 /private/
Notice how my folder doesn't have extended attributes.
There is another difference - compare your listing:
ls -ldO@ /private
drwxr-xr-x 6 root wheel - 204 Dec 7 10:24 /private/
with the first line of mine:
$ ls -ldO@ /private
drwxr-xr-x@ 6 root wheel hidden 204 Nov 4 2009 /private
com.apple.FinderInfo 32
Note the word "hidden" after "wheel" in my listing. That is a file flag, which can be added or removed to an item with the Terminal command chflags. *Man chflags* includes the following in its list of flag keywords:
hidden set the hidden flag \[Hide item from GUI]
An item will be hidden from Finder if its name begins with a period, OR if it carries a "hidden" flag.
I did some experimenting - I removed the hidden flag from my own /private folder with:
sudo chflags nohidden /private
Two things happened:
1) The /private folder became visible in Finder
2) Both the "hidden" flag and the "com.apple.FinderInfo" extended attribute disappeared from my listing, such that it was now the same as yours:
$ ls -ldO@ /private
drwxr-xr-x 6 root wheel - 204 Nov 4 2009 /private
I then added back the hidden flag with
sudo chflags hidden /private
Two things happened:
1) The /private folder became invisible again.
2) Both the hidden flag and the extended attribute re-appeared.
$ ls -ldO@ /private
drwxr-xr-x@ 6 root wheel hidden 204 Nov 4 2009 /private
com.apple.FinderInfo 32
Bottom line: I would still try the command I gave you earlier:
sudo chflags hidden /private

WCF Published Orch - Could not find a base address that matches scheme http for the endpoint with binding MetadataExchangeHttpBinding

I have an orchestration published as a web service. It was working fine on our test environment, we deployed to production, and now getting this error. The website wouldn't go in the BizTalk MSI, so we copied the files. We reset the Authentication
to match the test system (we are using Basic Auth).
When we try to browse the webservice in the browser, it prompt for userid/password, we enter it, then it gives the following error.
I'm not even sure what it means by "base address", if URL was https://prod.mydomain.com/myapp/myservice.svc, would https://prod.mydomain.com be the based address? In the test environment, the URL is https://test.mydomain.com/myapp/myservice.svc.
In both environments, we have a customer calling this webservice.
Also, I don't know what it means "scheme http". We are using https:... on the URL.
I'm thinking this is either security related, something to do with the app pool being different, or maybe something to do with bindings.
Thanks,

When you want to migrate Web Applications from one environment to other there are multiple ways to achieve it.
1) Migrate in MSI- Export MSI and select the option for your Web Application, however I don't recommend this option
2) Is to browse the folder for Web Application(Right click on web app and browse). Copy this folder(normally within inetpub folder) and take it to the inetpub folder of other environment. Later from the IISManager create application.
Are you not using the same Binding file?
Check you web.config file and see if the endpoint is configured for mexHTTpBinding.
Old: binding="mexHttpBinding"
New: binding="mexHttpsBinding"
web.config snippet:
<services>
<service behaviorConfiguration="ServiceBehavior" name="LIMS.UI.Web.WCFServices.Accessioning.QuickDataEntryService">
<endpoint behaviorConfiguration="AspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="webBinding"
contract="LIMS.UI.Web.WCFServices.Accessioning.QuickDataEntryService" />
<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
</service>
Also look into the below article- How to fix: "Could not find a base
address that matches scheme http for the endpoint with binding WebHttpBinding" Errors
Moving to https = Could not find a base address that matches scheme

A problem with bind variables in a shuttle

Hi
After days of research I cannot come up with a solution to this problem which I hope will be easy to describe.
I'm working on an apex.oracle.com workspace (4.02).
I have a page with
a) a region with tree which works well populated by a list of roles and users
b) a region with a shuttle with the following sql
List of values
select SOB_DISPNAME, SOB_ID
from VIEW_SYSTEMOBJECT
order by SOB_DISPNAME
Source
SELECT SOB_ID FROM VIEW_OBJECTSECURITY_GRANTED WHERE U_ID = :P19_SELECTED_ID
:P19_SELECTED_ID is a hidden textbox with the currently selected users id.
The above works very well - I select a user from the tree and the shuttle lhs populates with unselected object names and the rhs with objects selected for the user. A submit button drives a page process which clears out and then inserts the selection into a the table (objectsecurity)
So far so good.
I added a list box to the shuttle region (:P19_SOB_TYPE_LIST) so that the data being worked on could be filtered by type, its driven by a LOV that produces a value or 'PAGE', 'REPORT' ... etc.
I updated the above SQL to be
List of Values
select SOB_DISPNAME, SOB_ID
from VIEW_SYSTEMOBJECT WHERE SOB_TYPE = :P19_SOB_TYPE_LIST
order by SOB_DISPNAME
and the source
SELECT SOB_ID FROM VIEW_OBJECTSECURITY_GRANTED WHERE U_ID = :P19_SELECTED_ID AND SOB_TYPE = :P19_SOB_TYPE_LIST
So now I would expect that if 'PAGE' is selected in the list box then only objects that are pages will be seen.
However nothing at all appears.
If I substitute the bind variable :P19_SOB_TYPE_LIST for 'PAGE' ... WHERE SOB_TYPE = 'PAGE' it works perfectly. So why does :P19_SELECTED_ID do it's job but not P19_SOB_TYPE_LIST ?
I am probably making some ridiculously simple mistake but I just cannot spot it; is my syntax wrong?.
The session state is persisting so that I can see the value of :P19_SOB_TYPE_LIST being set to PAGE
Any help with this would be very much appreciated.

Hi Dirk
Thanks for that which looked promising!
I added P19_SOB_TYPE_LIST as the Cascading LOV Parent Item and removed it from the where clauses of both SQL's and the result was that all types are shown; corresponding to my original position.
I then added the where clause back to the LOV SQL and both shuttle boxes are blank again
I added back to the source SQL and again both boxes empty
Finally I removed the where clause from the LOV SQL (the only other combination) and again lhs box populated with all rows (not filtered) and rhs box blank.
So unfortunately that doesn't seem to have fixed it.
Many thanks for the help and any more will be greatly appreciated.
Regards
Charles

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

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.

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.

Report query with bind variable

Trying to create a report query for xsl-fo print. For output format I pick "derive from item" then pick the item name from the list, on the next screen, I paste the query with the bind variable. on the next step test query, I always get "data not found" regardless what value I type in. This is the same query that I ran under sql commands without any issues.
Does anyone run into the same issue as I have when attempted to create a query with bind var ? There is no problem creating a query without bind varibles. . thanks.
Munshar

Hi, please did you get any solution to this issue? I am having similar challenge right now.
select     EMP.DEPTNO as DEPTNO,
     DEPT.DNAME as DNAME,
     EMP.EMPNO as EMPNO,
     EMP.ENAME as ENAME,
     EMP.JOB as JOB,
     EMP.MGR as MGR,
     EMP.HIREDATE as HIREDATE,
     EMP.SAL as SAL
from     SCOTT.DEPT DEPT,
     SCOTT.EMP EMP
where EMP.DEPTNO=DEPT.DEPTNO
and      DEPT.DNAME =upper(:dname)
This run perfectly in sql developer, toad, and even inside publisher if I login directly to publisher to create report.
Generating this same query in shared component query builder and testing it returns no data found. If I remove the last line, it works. but with the last line, it return no data found. It seems no one has been able to provide solution to this issue

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?
tkprof output from Apex trace with bind variable is below...

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?

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.

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?

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.

ADF - ViewObject (with Bind Variable) Bind to Table- JDeveloper 10.1.3 EA

Hi all,
1.- This is the situation:
In JDeveloper 10g 10.1.3 EA I have two JSP JSF Pages with bind automatically coponents (backing bean).
- In the first page I can select a value from a list. Then, when I press the "Accept" ADF Command Button, the selected value is stored in a property called "rutEntidad" of a Session Managed Bean and the Flow Control is passed to the second page.
- In the second page I have an ADF Table (called tablePolizas) bind to a ViewObject (I drop the ViewObject from the Data Control Palette to the Page - ADF Read-Only Table ). The ViewObject has a Bind Variable called RUT_ENTIDAD. When this page is loaded, value in the rutEntidad property of Session Managed Bean is passed to the ViewObject in order the ADF Table show filtered data . Also in this page there is a "back" ADF Command Button to the first page. The filter mechanism is performed in the getTablePolizas method in the backing bean of the second page, like this:
//**** The backing bean of the second page *****
package cl.bicevida.view.backing;
public class CrearUsuario {
private CoreTable tablePolizas;
public CoreTable getTablePolizas() {
DCBindingContainer dcbc;
DCControlBinding cb;
String rutEntidad;
FacesContext ctx =FacesContext.getCurrentInstance();
ValueBinding vb =
ctx.getApplication().createValueBinding("#{SessionManager.rutEntidad}");
rutEntidad = vb.getValue(ctx).toString();
dcbc = this.getBindingContainer();
cb = dcbc.findCtrlBinding("VoPolizasAsociadasEntidadExterna1");
ViewObject vo = cb.getViewObject();
vo.setNamedWhereClauseParam("RUT_ENTIDAD", rutEntidad);
vo.executeQuery();
return tablePolizas;
2.- And this is the problem:
The first time all works fine... then I press the "back" ADF Command Button to the first page (and NOT the back button of the browser). The second time, if the numbers of rows returned by the ViewObject is different than the first time, the application throws this message (but not crash):
validation - JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-35007: Row currency has changed since the user interface was rendered. The expected row key was oracle.jbo.Key[1 ]
validation - JBO-35007: Row currency has changed since the user interface was rendered. The expected row key was oracle.jbo.Key[1 ]
Well, I had read the "Generic Approach for Back-Button-Friendly Web Rowset Paging" article of Steve Muench in http://www.oracle.com/technology/products/jdev/tips/muench/paging/index.html
but I think here have another problem.
3.- The questions:
Which is the cause of this problem?
How I can solve it?
What another way I can programmatic pass a parameter to a ViewObject connected to a table?
Thanks!!!

Another thing: the used strategy to obtain a binding container is explained by Steve Muench http://www.oracle.com/technology/products/jdev/tips/muench/1013eabinding/index.html:
Next, you can use JDeveloper's Overview tab of the faces-config.xml file editor to configure a managed property. Define the managed property name as bindingContainer to match the property in your bean, and set the class to the fully-qualified name of the DCBindingContainer class. You can use the (Browse...) button to quickly locate the class using the new JDeveloper 10.1.3 class browser. Just type in the first few letters of the DCBindingContainer name, and then select the class. Edit the new managed property and set its Value to the JSF EL expression: #{bindings}.

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?

SQL query with Bind variable with slower execution plan

I have a 'normal' sql select-insert statement (not using bind variable) and it yields the following execution plan:-
Execution Plan
0 INSERT STATEMENT Optimizer=CHOOSE (Cost=7 Card=1 Bytes=148)
1 0 HASH JOIN (Cost=7 Card=1 Bytes=148)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'TABLEA' (Cost=4 Card=1 Bytes=100)
3 2 INDEX (RANGE SCAN) OF 'TABLEA_IDX_2' (NON-UNIQUE) (Cost=3 Card=1)
4 1 INDEX (FAST FULL SCAN) OF 'TABLEB_IDX_003' (NON-UNIQUE)
(Cost=2 Card=135 Bytes=6480)
Statistics
0 recursive calls
18 db block gets
15558 consistent gets
47 physical reads
9896 redo size
423 bytes sent via SQL*Net to client
1095 bytes received via SQL*Net from client
3 SQL*Net roundtrips to/from client
1 sorts (memory)
0 sorts (disk)
55 rows processed
I have the same query but instead running using bind variable (I test it with both oracle form and SQL*plus), it takes considerably longer with a different execution plan:-
Execution Plan
0 INSERT STATEMENT Optimizer=CHOOSE (Cost=407 Card=1 Bytes=148)
1 0 TABLE ACCESS (BY INDEX ROWID) OF 'TABLEA' (Cost=3 Card=1 Bytes=100)
2 1 NESTED LOOPS (Cost=407 Card=1 Bytes=148)
3 2 INDEX (FAST FULL SCAN) OF TABLEB_IDX_003' (NON-UNIQUE) (Cost=2 Card=135 Bytes=6480)
4 2 INDEX (RANGE SCAN) OF 'TABLEA_IDX_2' (NON-UNIQUE) (Cost=2 Card=1)

TABLEA has around 3million record while TABLEB has 300 records. Is there anyway I can improve the speed of the sql query with bind variable? I have DBA Access to the database
Regards
Ivan

Many thanks for your reply.
I have run the statistic already for the both tableA and tableB as well all the indexes associated with both table (using dbms_stats, I am on 9i db ) but not the indexed columns.
for table I use:-
begin
dbms_stats.gather_table_stats(ownname=> 'IVAN', tabname=> 'TABLEA', partname=> NULL);
end;
for index I use:-
begin
dbms_stats.gather_index_stats(ownname=> 'IVAN', indname=> 'TABLEB_IDX_003', partname=> NULL);
end;
Is it possible to show me a sample of how to collect statisc for INDEX columns stats?
regards
Ivan

ExecuteWithParameter with Binds on several view objects

I thought I knew how to do this, but it has been a month or two, and can't seem to get the syntax right. I would really appreciate some guidance on this.
I'm using jdev 11 to create a basic page using ADF Faces. In the model, I have three seperate read only view objects based on queries I created in SQL Developer. I also have two lookup tables for use in LOVs to display names for IDs. In one of the views, I added two LOVs for id columns. I have one more lookup that displays name, id for Tech's.
All three views have the same named bind variable - :TechID
What I want is to have a single select box that displays the name column from Tech that will return the ID for TechID. When the user clicks the ExecuteWithParms, all three views should be refreshed and re-queried with the new bind value, and display the results. To see this work, I have been working with readonly tables, but eventually hope to use graphs for the three views.
Here is the general layout that I am trying to achieve.
Select One Choice (List of Techs with display set to name, and the return set to ID)
ExecuteWithParams button. Currenly have table1, table2, table2 in the partialtriggers field.
table1
ViewObject1 that has a named bind of :TechID
table2
ViewObject2 that has a named bind of :TechID
table3
ViewObject3 that has a named bind of :TechID
This seems like it should be easy to setup. Can this be done declaratively, or do I need code. If I need code, can I get a few hints?
Is there an example that has something similar that I can gleen how to accomplish this?
Thanks, Ken

Timo et al,
I still can't seem to get this to work. I finally worked through a problem with JDeveloper working (Feels like it has been April 1st for a week straight! (American Humor)). In trying to simplify this, I am asking if someone can create the following example use case based on the HR schema. I'm not asking for a paper, just 15 or so minutes from someone that is good at this to create a working example. Also, send me a zipped copy of the project, or make it available on your blog or other downloadable location.
Thanks for any help with this to really understand how to get JDeveloper to work for me.
Here are the specifics for a Highly desired example:
This is based on HR schema.
Read Only View Objects
-- LOCATION_LKUP
select
(street_address || ' ' || city || ', ' || state_province || ' ' ||to_char(postal_code) || ' ' || country_id) as location_name,
location_id
from
locations
order by country_id, location_name;
-- ViewObject DepartmentStuffView
select *
from departments
where location_id = :LOC_ID;
-- ViewObject EmployeeStuffView
select * from employees
where department_id in (select department_id
from departments
where location_id = :LOC_ID);
-- Modify the AppService and ViewObjects to expose Java code to
-- modify the (name)Impl.java file
AppService Code
public void updateViews(String locationID) {
     // Get a reference to the ViewObjects
DepartmentStuffView vo1 = (DepartmentStuffView) getDepartmentStuffView1();
EmployeeStuffView vo2 = (EmployeeStuffView) getEmployeeStuffView1();
     // Now have each view object requery itself with the new parameter
vo1.updatewithParam(locationID);
vo2.updatewithParam(locationID);
ViewObject Code
-- In both ViewObjects
-- (DepartmentStuffViewImpl.java and EmployeeStuffViewImpl.java),
-- add the following code at the bottom
public void updatewithParam(String locationID) {
     setTechID(locationID);
     executeQuery();
Layout:
Location Name: ComboBox <== Displays LOCATION_NAME, Returns LOCAION_ID
<Run Report> <== Button to run the process
Table1
The view object DepartmentmentStuffView
Table2
The View Object EmployeeStuffView
Expected Behavior:
Change the location in combo box and press the run report button.
The data in both views with bind variables get updated.
Extension:
Page can have search with multiple filters. The AppService can control
which views get updated with which values depending on selections. Common
use case.
Thanks so much, Ken
