Dynamically setting where clause parameter before the page load
Hi Experts,
I do have the following requirement.
I am working on jsf page in ADF10.1.3.3. I have a View Object which displays the results on the screen. Can someone provide me some example where I can dynamically set the where clause parameter to my Query in VO before the Page Load happens(By Overriding the Prepare Model) and display results on screen.
Thanks
Hi,
Thanks for yor advice.
I need to write the method in Prepare Model method when the page loads and not in AM.
Here in the page there is no action as such.
On the Page load we need to directly set the Where Clause on the VO.
Provide me some examples if any.
Thanks

Progress bar/Icon before the page loads
Hi,
I am having a page which takes 1-2 mins to load and render the data now i want to display animated icon/progress-bar immediately the page pops up(ie. when blank). Ive already done progress bar on the page load but in this case i want it to display much early when the page is still blank, any idea please. If this is not doable in Apex i might borrow JS/JQuery......thanks all.All,
I got this issue to work in a better way using Skillbuilder's pop-up plugins but again I am having issue with that too as described below,
The first time the popup page comes up the background is totally black, how can i change this to make it meaningful color?

Set where Clause parameter using UIX
I am using uiXML to generate a table which is associated to a ViewObject. The query of the ViewObject has bind variable for date. I would like to display a report (i.e table) with the values from ViewObject corresponding to dates (from & to) set using the bind variable. In other words, I would like to set the value for the bind variable from UIX just before displaying the table. My code is as follows:
<bc4j:rootAppModuleScope name="QnAMainRepView1AppModule">
<contents>
<form name="QnAFrm">
<contents>
<bc4j:viewObjectScope name="QnAMainRepView1">
<contents>
<bc4j:table name="QnATbl" width="100%">
<bc4j:keyStamp>
<bc4j:rowKey name="key"/>
</bc4j:keyStamp>

</contents>
</bc4j:column>
<column>
<columnHeader>
<sortableHeader text="Local Time"/>
</columnHeader>
<contents>
<dateField readOnly="true" value="2003-01-25">
<onSubmitValidater>
<date dateStyle="long"
pattern="MM-dd-yyyy 'at' hh:mm:ss"/>
</onSubmitValidater>
</dateField>
</contents>
</column>
</contents>
</bc4j:table>
</contents>
</bc4j:viewObjectScope>
</contents>
</form>
</contents>
</bc4j:rootAppModuleScope>
In the above, QnAMainRepView1 is the ViewObject which has bind variables. How do I set the value for the bind variable before the table is drawn?
Thank you very much for your help.

Issue with dynamically setting where clause in OAF
Hi All,
I have a View object having the query below:
SELECT rownum LINENUM,
B.line_id LINE_ID,
B.INVENTORY_ITEM_ID INVITMID ,
B.QUANTITY_DELIVERED PICKQTY
from MTL_TXN_REQUEST_HEADERS A,
MTL_TXN_REQUEST_LINES B
WHERE A.HEADER_ID=B.HEADER_ID
AND A.MOVE_ORDER_TYPE=2
AND 'on'=:1
AND B.TO_SUBINVENTORY_CODE=NVL(:4,B.TO_SUBINVENTORY_CODE)
AND A.request_number=NVL(:5,A.REQUEST_NUMBER)
UNION ALL
SELECT rownum LINENUM,
a.wip_entity_id LINE_ID,
a.INVENTORY_ITEM_ID INVITMID,
a.QUANTITY_ISSUED PICKQTY
FROM WIP_REQUIREMENT_OPERATIONS a,
eam_work_orders_v b
WHERE a.wip_entity_id=b.wip_entity_id
AND 'on'=:2
AND a.ATTRIBUTE2=NVL(:4,a.ATTRIBUTE2)
and b.wip_entity_name=NVL(:6,b.wip_entity_name)
I need to pass dynamically a condition to my where clause that i can handle it by defining two bind parameters in the vo query and can pass it but the problem is the bind variable contains a string like 1311,13112,14445 that i need to pass for a field such as B.line_id in the first query and b.wip_entity_id in the second query so when i am trying by passing the string as one value it is working fine but for value separetd by comma it is giving prob.
so i tried by passing dynamic where clause but it is everytime executing for first clause only how i can pass dynamically both the queries.
vo.setWhereClause("LINE_ID in "+wherclause);
please help me out
Thnaks
DebHi Gaurav,
Thnaks for the reply i tried belwo way u suggested but the query is executing multiple times and i am not getting the correct data as expected.
public void processPOData (String wherclause)

String query =vo.getQuery();
String newwhereclause ="LINE_ID = "+wherclause;
StringBuffer stringbuffer = new StringBuffer();
stringbuffer.append("SELECT * FROM (");
stringbuffer.append(query);
stringbuffer.append(") where ");
stringbuffer.append(newwhereclause);
ViewDefImpl viewdefimpl = getXXDPECONTAINLINESVO1().getViewDefinition();
viewdefimpl.setQuery(stringbuffer.toString());
vo.reset();
vo.clearCache();
vo.executeQuery();
System.out.println("where clause:"+wherclause);
in my log file the query is forming like below:

I get a flash of blue background before the page loads.
its happening on this page I created. its a duplicate from an older page in where i use the framework.
but all other pages on site ae fine.
please help

The blue is coming from your use of bgcolor="#003366" in your first row cell which appears while waiting to load all those graphics. Once the graphics are cached, I don't see the blue anymore.
Change this:
<td colspan="7" bgcolor="#003366">
to this:
<td colspan="7">

Edited by: user621288 on Jun 17, 2009 4:11 PMThere are two ways:
1. Uncheck "Query List Automatically" under List UI Hints in the view object overview xml.
2. In the query add "where 1=:bnum and 1 is not null" and execute the query in the LaunchPopupEvent
public void userIdId_launchPopupListener(LaunchPopupEvent launchPopupEvent) {
DCIteratorBinding myListIter = (getItrtBindings("MyLovViewObj1Iterator"));
ViewObject vo = myListIter.getViewObject();
NavigatableRowIterator myItemList = myListIter.getNavigatableRowIterator();
Row row = myItemList.first();
Object[] val = row.getAttributeValues();
ViewRowSetImpl vor = (ViewRowSetImpl)val[row.getAttributeCount() - 1];
vor.setNamedWhereClauseParam("bnum", new BigDecimal(1));
vor.executeQuery();

JSF action before the page is displayed?
Hi all,
What's the best way to execute a backing bean method before the page is rendered?
I have to fill out some selectOneMenus on the page with a backing bean method.
Will the onload JavaScript function in the <body> tag do this for me? How does one call a JSF method from JavaScript?
Thanks for any help!
IlluWhy not just bind the value of a selectOneMenu to a list of SelectItems, like this:
<h:selectOneMenu styleClass="selectOneMenu" id="acctprodMenu" value="#{accountServiceMappingAction.mappingBean.acctPrdId}" >
<f:selectItems value="#{adjustmentsInit.accountProducts}"/>
</h:selectOneMenu> Where in the adjustmentsInit bean, there is a method like this:
public List getAccountProducts() {
ArrayList temp = new ArrayList();
Iterator itr = someService.getAccProdList.iterator();
while (itr.hasNext()) {
AccountProduct acct = (AccountProduct) itr.next();
SelectItem item =
new SelectItem(
new Integer(acct.getAccountProductId()),
acct.getAccountProductName());
temp.add(item);
return temp;
}This way, once you load the page, it will have what you need in it. -
Using a dummy where-clause to force the use of an index
I notice that an index only gets used when I use the index key in the where clause. Should I use a dummy where clause to force the index to be used?
SQL> create table emp (
2 empno NUMBER(5),
3 empname VARCHAR2(15) );
Table created.
SQL> create index idx_emp_no on emp (empno);
Index created.
SQL> insert into emp (empno, empname) values (1, 'Peter');
1 row created.
SQL> set autotrace traceonly;
SQL> select empno from emp;

|* 1 | INDEX RANGE SCAN| IDX_EMP_NO | 1 | 13 | 1 (0)| 00:00:01 |
As you can see, using a dummy where clause (empno > 0), I manage to reduce the cost from 3 to 1.Again. Be careful with comparisons. But I like the discussion. It is usefull to carefully look at what happens "behind the scenes" and find a sensible explaination for that.
Your new scenario now is different. By selecting one specific row instead of selection all you already made an assumption. That only one or few of the rows are returned. Andre's statement still is correct. Now the CBO will prefere the index scan.
The CBO now has to decide between two options.
Option a) use the index.
This means =>
Step 1: Access the index to find the value
Step 2: Access the table using the rowid that was found in the index leaf entry.
Option b) scan the full table
This means =>
Step 1: Iterate over all rows of the table
Step 2: Apply a filter condition (empno = :x)
We can see this execution plan by adding a hint to the query.
select /*+ FULL(emp) */ * from emp where empno = 1;This hint will force the CBO to access the table emp using a full table scan.
The cost in my environment for option B is 3.
Option A has a cost with 2. Therefore the CBO prefers Option A.
However this can easily change.
Consider the following
begin
for i in 1..1000 loop
insert into emp (empno, empname) values (1, 'Employee');
end loop;
end;
commit;
execute dbms_stats.gather_table_stats(user,'EMP');The run the select again.

Bc4j: set where clause at runtime for view objcet ?
how to set where clause for a view object that is not put in a subselect at runtime ?
select a.para_id, b.para_para_id
from table1 a, table2 b
need to set at runtime either:
where a.para_id = b.para_para_id
or:
where a.para_id = b.para_para_id(+)
problem is that bc4j is useing it as followed:
select * from (
select a.para_id, b.para_para_id
from table1 a, table2 b
) where (a.para_id = b.para_para_id(+))
cant use outer join like this
any suggestionsIf you do not want to issue the framework built query, you may want to set the query for a VO yourself instead of setting just the where clause by using setQuery() api. TO revert back to framework built query, call setQuery(null).
This way, when you need the xtra where-clause and not the "innerSQL stuff", you can build a custom sql with whereclause etc, and call setQuery(), execute that SQL, perform your tricks with the VO and then when the VO is usage is done, reset the VO query to original by calling setQuery(null). -

I have the following schema:
<?xml version="1.0"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tns="CountryRiskService"
targetNamespace="CountryRiskService"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="CountryRiskParameters">
<xs:complexType>
<xs:sequence>
<xs:element name="countryId" type="xs:int" minOccurs="1" maxOccurs="unbounded"/>
<xs:element name="catA" type="xs:boolean" minOccurs="0" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
I am passing this into my Logical Data Service, what I want to do is create a dynamic XQuery where clause if the catA field is populated, ignore it if it isn’t, so basically, I want to be able to create a dynamic query based on the parameters requested, so I have the following XQUERY:
declare function tns:getCountries($countryRiskInput as element(ns7:CountryRiskParameters)) as element(ns0:CountryRiskInfo)* {
for $tbl_high_risk_countries in ns1:tbl_high_risk_countries()
where $countryRiskInput/ns4:countryId = $tbl_high_risk_countries/country_id
where $countryRiskInput/ns4:catA = $tbl_high_risk_countries/risk_catA
I really thought that DSP would be able to handle this on the fly since the element is optional but if I don’t populate it, I get nothing back, the idea is I want to increase the number of elements in my schema so my consumers have the ability to filter the results they want, so above, I don’t want the second where clause if catA isn't specified, any ideas how to accomplish this?Simply add the disjunction of the input being empty.
for $tbl_high_risk_countries in ns1:tbl_high_risk_countries()
where $countryRiskInput/ns4:countryId = $tbl_high_risk_countries/country_id
where ( $countryRiskInput/ns4:catA = $tbl_high_risk_countries/risk_catA or empty( $countryRiskInput/ns4:catA )
But suppose you have 27 different elements that you might want to filter on - the xquery gets long and ugly. You might want to looking into using FilterXQuery. Visit http://edocs.bea.com/aldsp/docs25/, search on FilterXQuery, look for the tutorial.
If your queries get more complicated, you would do well to look into generating ad hoc queries. (edocs as well).
