Bc4j, struts and query form (where)

I have a query form on 1 table created by the wizards (bc4j - struts).
For ex. in the name field I can insert 'Dimi' and the query form will find my record.
But when somebody inserts 'dimi' (not initcap), he doesn't find my record.
How can I adapt the default where clause in the query like eg. WHERE UPPER(FIRSTNAME)=document.form.field.toUpperCase(); ??
In the next release this should be more simple!

You can call setUpperColumns(true) on any instance of your view criteria row that you want to apply this UPPER() function to.
Do you have a functional index at the database level on the UPPER(FIRSTNAME) function?
If not, the query will do a full table scan with the UPPER(FIRSTNAME) in there.

Struts and JSF

I have an Action from Struts. This controls the data in the code behind bean.
After I call submit, how do I go Back to the Struts actions? the JSF navagation does not allow navigating to a servlet.

Hey Shay,
We have quite a large application based entirely on Struts. There is a keen interest in migrating to JSF, but in an incremental fashion. I did a fair amount of googling and almost everything i came up with , was purely theory oriented, are there any resources online , which clearly give examples/tutorials for doing a step by step migration to JSF from Struts. Couple of other questions that i dont seem to find an answer to with regards to the Integration of struts and JSF
1) I understand BC4J, struts and JSF can be integrated together, does the same hold for ADF ? there was a similar forum post back in 2005 , where they said this is yet to be done, do we have this integration with Jdev 10.1.3 ?
2) If i were to use only the jsf UI component tags as a first step in my struts application , what is the equivalent for the page definition file of JSF in struts, as in how would i achieve the binding ?

How to find out where a query is used in a FMS and or Form?

Hi Experts,
How can I find out quickly where a query is used in which fms and / or form?
thx,
Richard

Hi Richard,
Try this:
SELECT T2.FormID, T2.ItemID, T2.ColID,
T1.CatName,T0.Qname FROM [dbo].[OUQR] T0
INNER JOIN [dbo].[OQCN] T1 ON T0.QCategory = T1.CategoryId
INNER JOIN [dbo].[CSHS] T2 ON T2.QueryId = T0.IntrnalKey
ORDER BY T2.FormID
Thanks,

Query form requires Logical operators and/or Quotes

In ORACLE 9I Jdeveloper beta I used the BC4J JSP wizard to create a - Query Form. The query form looks nice and runs except I have to also include the logical operators (= > <) and Quotes. For example to query on the name Joe I have to enter it as ="JOE". If I use JOE it gives me a JSP error. The error message shows the generated Select statment with the where clause JOE but is missing the "=" and quotes.
How do I hard code the "=" and quotes around strings so that the user doesn't have to?

Could query form and result table display at seperate pages

we are new at html db, there are a few of questions we need to clear before we make decision to use HTML DB to develop our next version of application: (I seperate them at differenct topics).
* Could query form and query result table display at differenct pages?
Thanks
Lei

yeah, this is surely possible...and quite easy. you'd just set your form page up as you'd like. put a button on that page with a branch to your report page. then have your report query refer to the items you defined on the form page. so if your form page had an item called P1_JOB and P1_DEPTNO you could have your report use those items with a query like...
select ename, job, sal, empno, deptno
from emp
where :P1_JOB = job
and :P1_DEPTNO = deptno
...hope this helps,

Different LOVs in af:query and af:form for the same VO attribute

Hi,
We need to display different LOVs in af:query and af:form for the same attribute in VO.
Is it possible to use LOV Switcher for this ?
What condition can we use in LOV Switcher attribute to check if it is View Critearia row or VO row ?

We have a VO attribute "User" which needs to be displayed as LOV in a Search Panel ( af:query component created using View Critearia ) and in a af:form.
When this VO attribute is displayed in search panel, in LOV, we need to show all users.
When this VO attribute "User" is displayed in a form for editing, in LOV, we need to show only active users.
For this, we created two LOVs "ActiveUsersLOV" ( which shows only active users ) and "AllUsersLOV" ( which shows all users ) on VO attribute "User".
LOVSwitcher attribute should return "ActiveUsersLOV" if the LOV is displayed in form and "AllUsersLOV" if the LOV is displayed in search panel.

Bad query plan for self-referencing CTE view query and variable in WHERE clause. Is there way out or this is SQL Server defect?

Please help. Thank you for your time and expertise.
Prerequisites: sql query needs to be a view. Real view is more than recursion. It computes location path, is used in JOINs and returns this path.
Problem: no matter what I tried, sql server does not produce 'index seek' when using variable but does with literal.
See full reproduction code below.
I expect that query SELECT lcCode FROM dbo.vwLocationCodes l WHERE l.lcID = @lcID will seek UNIQUE index but it does not.
I tried these:
1. Changing UX and/or PK to be CLUSTERED.
2. query OPTION(RECOMPILE)
3. FORCESEEK on view
4. SQL Server 2012/2014
5. Wrap it into function and CROSS APPLY. On large outer number of rows this just dies, no solution
but to no avail. This smells like a bug in SQL Server. I am seeking your confirmation.
I am thinking it is a bug as variable value is high-cardinality, 1, and query is against unique key. This must produce single seek, depending if clustered or nonclustred index is unique
Thanks
Vladimir

Link to query Form and auto-execute

What is the secret after creating a link from a report for example, to not only pass the link parameter to a query form, but to cause the form to execute the query.
Currently my query form shows the passed parameter but doesn't auto-execute..

This is exactly the same question I have and there are lots of similar questions in this forum. None of them have replies. Is this question still unanswerable?

In SharePoint 2013, we can take use of REST API or Client Object Model to access the SharePoint objects like Form Library.

Simple Select query with 'where', 'and', 'between' clauses takes time

Hi,
I have a select query as below
SELECT * FROM (SELECT a.*,ROWNUM currentStartRecord From (select ai_inbound.ai_inb_seq tableseq,'AI_INBOUND' tablename,'INBOUND' direction,ai_inbound.appl,ai_inbound.ai_date datetime,ai_inbound.ic_receiver_id pg_id,ai_inbound.ic_sender_id tp_id,ai_inbound.session_no,ai_inbound.ic_ctl_no,ai_inbound.msg_set_id msg_type,ai_inbound.appl_msg_ctl_no reference_no,ai_inbound.fg_version version,ai_inbound.msg_status status,ai_inbound.input_file_name,ai_inbound.output_file_name,ai_inbound.ack_file_name from ai_inbound where ai_inbound.appl = ? and ai_inbound.ai_date between ? and ? )a where ROWNUM <= 49)where currentStartRecord >= 0
The above query takes longer time through application than expected when the date fields are passed whereas it works fine when no date fields are passed. We are using oracle9.2 version of the database. All the indexed columns and partitioned indexed columns are rebuild.
Kindly let me know how can i tune up the query to improve the performance.
Thanks

Help in Ad-hoc query and Hr form editor

any body have material links of Ad-hoc query(it means how the reports are generated with Ad-hoc query) and Hr form editor(with examples) plz forward it to me???????????

Hi,
HR Ad Hoc Query is the special version of InfoSet Query with the HR object selection.
You can find the system documentation here:
http://help.sap.com/saphelp_erp2005vp/helpdata/en/f9/cc9138e4a0341fe10000009b38f8cf/frameset.htm
However I doubt the use of documentation of the query generator. So what is your concrete question?
Or in any R/3 via application help of transaction SQ01.
Also HR580 is a good course.

Link for BC4J Struts-JSP and Tiles

Hi,
I have a JSP-Struts application. By the default generation, JDeveloper build a main.html Page. This page have many Frames and one Frame is "navFrame". On this frame I have a link for a JSP Page : Browse. The call is OK. No Problems.
No I have another Page with Tiles :
<template:insert page="IMDLayout.jsp" flush="true">
<template:put name="title" value="Invoices Interface" />
<template:put name="header" value="/tiles/common/header.jsp" />
<template:put name="footer" value="/tiles/common/footer.jsp" />
<template:put name="menu" value="/tiles/common/menu.jsp" />
<template:put name="body" value="VInvoiceUsersView1_Browse.do" />
</template:insert>
The "body" Tiles call the same JSP Page as the link on the "navFrame", but now I have the following error :
[ServletException in:VInvoiceUsersView1_Browse.do] Response has already been committed'
Why ?
Please help me, I need a solution. Does somebody use BC4J/Struts/Tiles ? Any Experience ? Problem ?
Thanks

Need help with BC4J/Struts application using a Stored Procedure

Hi,
I am doing a proof of concept for a new project using JDeveloper, Struts and BC4J. We want to reuse our Business logic that is currently residing in Oracle Stored Procedures. I previously created a BC4J Entity Object based on a stored procedure Using Oracle Stored Procedures but this stored procedure is a bit different in that it returns a ref cursor as one of the paramters. http://radio.weblogs.com/0118231/stories/2003/03/03/gettingAViewObjectsResultRowsFromARefCursor.html
I tried the above method, but I am having some trouble with it. I keep getting the error ORA-01008: not all variables are bound when I test it using the AppModule tester.
Here is the store procedure definition:

I created the view object in expert mode so there is no entity object. Can someone help? I don't have much time left to finish this.
Also, could I have done this from the Entity object instead of the view object by registering the ref cursor OUT parameter in handleStoredProcInsert()?
Thanks

I was able to get the input parameter by putting the following in my struts actions class
vo.setWhereClauseParam(0,request.getParameter("row0_SerialNum"));
The full code is:
package mypackage2;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import oracle.jbo.html.BC4JContext;
import oracle.jbo.ViewObject;
import oracle.jbo.html.struts11.BC4JUtils;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class LienCheckView1QueryAction extends Action
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
BC4JContext context = BC4JContext.getContext(request);
// Retrieve the view object instance to work with by name
ViewObject vo = context.getApplicationModule().findViewObject("LienCheckView1");
vo.setRangeSize(3);
vo.setIterMode(ViewObject.ITER_MODE_LAST_PAGE_PARTIAL);
// Do any additional VO setup here (e.g. setting bind parameter values)
vo.setWhereClauseParam(0,request.getParameter("row0_SerialNum"));
// default value for serialCollCd 1 is for Motor Vehicles
vo.setWhereClauseParam(1,new oracle.jbo.domain.Number(1));
// Default value for maxRows_allowed
vo.setWhereClauseParam(2,new oracle.jbo.domain.Number(20));
return BC4JUtils.getForwardFromContext(context, mapping);
This doesn't always work properly though. The first time I press the query button, the SerialNum parameter is still null, however if I re-execute the query by pressing the query button again. It will work, and return the rows. I always have to query twice. Also the SerialNum attribute is set to a String in my view object, it is a varchar column in the database, but some serial number I enter give a "Error Message: oracle.jbo.domain.Number ". This happens even though the underlying BC4J is returning values for the query. I also get a "500 Internal Server Error java.lang.ClassCastException: java.lang.String on my View object's code at line 65 which is
if (params.length>1) serialCollCdIn = (BigDecimal)params[1];
This is an input paramter to the oracle stored procedure that defaults to a Number value of 1.
Any idea what the problem is? Here is the full code for my view object:

Incorrect query forms in parent child relation

Hello
I am using jdev of RUP3 (Release 4) which is 11.1.1.6.2 and have following scenario
I have a ParentVO (ProfileVO) and a child VO(CreditReceiversVO) (child VO is basically extended from another VO not in this application and included as a jar library).
There a VL between ParentVO and ChildVO 1:* with two attributes ord_id and rule_id
On UI these two VO instances are dropped as parent child and I get exception on running page in logs saying RuleAssignementEO.ORG_ID invalid identifier.
Looking into the query formed by BC4J I see it as below which is clearly wrong as the alias RuleAssignmentEO is not visible for the outermost where clause. Please advise
"SELECT count(1) FROM (SELECT * FROM (SELECT /*+ FIRST_ROWS(10) */

invalid identifier means ,it representating that field currently not available in db-table.
so please refer db-table. whether field avialable or not?.
edited lately:
djbo.debugoutput=console did you use this :) it will say the query is send to server.
