Dynamically changing the WHERE clause in detail VO in Master Detail

Hi, I want to develop a search functionality, results will be in a table, which will have an inline table displaying the details per row found.
I have a MD defined trough viewlink. I do change the master VO at runtime (set the entire SQL), based on the criteria entered by the user.
Is there a way to change the VO at the detail end of the link at runtime - that is what I haven't been able to do.
I have read that the ADF framework creates internal VO for each master row, whenever accessed trough accessor (which is not I am trying to do). I haven't been able to find a way to get a hold of the REAL VO at the detail end and have its WHERE clause changed.
Changes to the "VO instance in AM" (same one used as a definition in the detail end in the ViewLink def) does not seem to reflect the detail VO.
I have a MasterView, DetailView, MasterDetailLink (MasterView->DetailView).
MasterDetailLink is used to create a table with inline detail table. At runtime:
1.get MasterView (from AM), change query trough setQuesry() - works.
2.get DetailView (from AM), change query trough addWhereClause() - does not work (no exceptions) - the results I am getting DO NOT reflect the conditions of the where clause, I mean the clause have not been addedd.
I 've looked at the logs (debug enabled) and it seems to me that there no "activities" related to the detail VO, even after the where clause of the VO from step 2 is changed.
Looks like there is a separate VO which I would like to get a hold of :)
Thanks, and sorry for the long explanation

After you have added a new where clause on the detail VO, try re-executing VO's query by DetailVO.executeQuery()
If it doesn't work try re-executing the MasterVO's query after you have added the where clause on the detail

JSP, DataWebBean: How to dynamically set the where clause of query and display record

Hi,
I am reposting this question as per suggestions made by Mr. Dwight.
I have used ViewCurrentRecord web bean to display records from EMP table. I have to use the Dept_Id_FK from the current
record of the EMP table to display corresponding records of Dept table. I have a view object called DeptView in my Business
Components which selects all the records from the Dept table.
How do I get the value of Dept_Id_FK and use it to display the required records of the Dept table?
I tried to declare a variable and get the value of Dept_Id_FK but it did not work. My code is as follows:
<%! String m_DeptId = null; %>
<jsp:useBean id="RowViewer" class="oracle.jbo.html.databeans.ViewCurrentRecord" scope="request">
<%
RowViewer.initialize(pageContext, "EMPApp_EMP_EMPAppModule.EMPView1");
RowViewer.setReleaseApplicationResources(false);
RowViewer.getRowSet().next();
m_DeptId = (String)RowViewer.getRowSet().getCurrentRow().getAttribute("DeptIdFk");
%>
</jsp:useBean>
Thanks.

First of all, Thank you very much for making use of the new topic format. It is very much appreciated.
As for your question, I think there are several different ways to accomplish what I think you want to do.
1. Create a view object that includes both Emp and Dept entities and join them there. In this case, your query would look something like this:
Select e.empno,e.name,...,d.dname,d.loc from emp e, dept d
where e.deptno = d.deptno
You should be able to create a JSP off of this view object that contains both the employee and department information. In this case, BC4J takes care of the foreign key to primary key coordination.
2. In order to set a dynamic where clause for a view, you need to do the following in your usebean tag:
rsn.initialize(application,session, request,response,out,"DeptView");
rsn.getRowSet().getViewObject().setWhereClause("deptno=" | | m_DeptId);
rsn.getRowSet().getViewObject().executeQuery();
rsn.getRowSet().first();
You will need to do this in a separate usebean tag from the EmpView, since the usebean can only initialize one view object.
In other words, you would have your ViewCurrentRecord bean tag for the EmpView, then a separate one for the DeptView where you use the above code to set the where clause to display just the information for the department you want.
Another option, but one I'm not sure would work as well, is to create a master-detail JSP to do this for you. Usually a master-detail is a one-to-many (one department to many employees). Your request appears to be the reverse, but might still be doable using the same mechanism.
You set up relationships between views in your BC4J project using View Links. If you used the BC4J project wizard and created default views, some of these links may have been created for you. They are created when BC4J detects a foreign key to primary key relationship in the database.
You can create your own View Links using the View Link wizard. Select your BC4J project node and choose Create View Link... from the context menu. You will be asked to select a source view (Emp), and a target view (Dept), then select the attribute in each view that related the two of them (deptno).
Next, you need to reflect this new relationship setting in your application module. Select your app module and choose Edit from the context menu. On the data model page, select the EmpView node in the Selected list. Now select the DeptView node in the available list and shuttle it over. You should see DeptView1 via yourlink appear indented under the EmpView node. Save and rebuild your BC4J project to reflect the changes.
In your JSP project, you can now have the wizard create a master-detail form for you based on DeptView1.
Let me know if the above answers your question, or if I have misunderstood what it is you wanted to do.

Pass values dynamically to the WHERE clause in SFAPI

Hi there
We have a requirement to pass values dynamically (in the run-time of the interface) to the WHERE condition to our SFAPI query.
Eg -
SELECT person, personal_information, address_information, phone_information, email_information, employment_information, job_information, compensation_information, paycompensation_recurring, paycompensation_non_recurring, job_relation, accompanying_dependent, global_assignment_information, direct_deposit, national_id_card, person_relation
 FROM CompoundEmployee
 WHERE last_modified_on >= to_date('LAST_RUN_DATE') AND
 last_modified_on <= to_date('CURRENT_RUN_TIME')
LAST_RUN_DATE is stored in a custom entity for which we execute another OData query. The custom entity is updated with the CURRENT_RUN_TIME once the interface has been executed successfully. So the next time the interface is run it picks up the LAST_RUN_DATE from the custom OData entity.
SAP PO has the functionality to run a dynamic query for OData adapters. Refer to Note 2051137 - PI Successfactors adapter : Dynamic odata query and single synchronous sfapi query
Eg - select fields from position (this is what you state in OData query path in the comms channel; this is static); and you have an advanced tab in comms channel where you mention dynamicquery and set it to true (this points to a XSD which has the keyword TOP, SKIP & FILTER in it).
This gets the filter values passed from the BPM from another query (from a OData cust_table).
So the whole query is - select fields from position filter field a = x field b = y etc. Field a field b are fields in position that are you passing values x and y in run time of the interface.
SAP PO also has the advanced tab feature for SFAPI for dynamic query.
Question is -
how to use it?
has anyone implemented this before?
What does XSD will look like?
How do we pass values to the fields to the Where clause for SFAPI.
Any ideas are welcome!

Arijit Das

Changing the where clause

Hi all,
Can anyone suggest an appropriate answer for this
I want to change the where condition in Reports (Developer 2000) dynamically (in runtime)
Thank you

Hi,
Try this in you pre-query trigger.
-- if you want to add to the where clause do this
-- first store the current where clause
C_WHERE := get_block_property('your_block', default_where);
IF <condition> THEN
c_where := 'desired_condition'||' AND '||C_where;
-- append your condition to the existing one.
END IF;
set_block_property('your_block', default_where,c_where);
or if you want to totally replace it just use the set_block_property in the trigger.
Hope this helps.

SQL query optimization by changinf the WHERE clause

Hi all,
I need to know about the SQL query performance improvement by changing the WHERE clause. Consider a query :
select * from student where country ='India' and age = 20
Say, country = 'India' filters 100000 records and age = 20 filters 2000 records if given one by one. Now can anyone tell if the performance of the query can be changed by changing the query like this :
select * from student where age = 20 and country ='India'
as first where clause will give 2000 results and next filter will be applicable on only 2000 rows. While in the former query first where clause would give 100000 rows and seconde filter, hence, would be applicable on 100000 rows???
Kindly explain.
Thanks in advance.
Abhideep

in general the order of the where condition should not be important. However there are a few exeptions where sometimes it might play a role. Sometimes this is called order of filter conditions. Among others it depends on RBO or CBO used, Oracle Version, Indexes on the columns, statistic information on the table and the columns, CPU statistics in place etc.
If you want to make this query fast and you know that the age column has much better selectivity then you can simply put an index on the age column. An index on the country column is probably not useful at all, since to little different values are in this column. If you are already in 11g I would suggest to use a composite index on both columns with the more selective in first position.

Change block where clause !!

hello !!
i wanna change the where clause of the data block in the runtime !!
i know that it can by Set_block_property
but it don't work with me !!!
can u give me an example for that !!
and what is the differance between default_where and onetime_where ,,, a two attributes in the set_block_property !!

and what is the differance between default_where and onetime_where ,,, a two attributes in the set_block_property !!Default_where remains with the block for every query until you change it using pl/sql. The onetime_where is set null automatically immediately after a single query is executed.
Look up the on-line help for Set_Block_Property on default_where and onetime_where, then click the onetime_where link, and read that.

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

Dynamically stating the field name in the WHERE clause

Hello All,
Consider the following select statement.
SELECT kunnr INTO TABLE gt_kunnr
 FROM kna1
 FOR ALL ENTRIES IN gt_table
 WHERE kunnr = gt_table-cust_id.
Suppose there is a case where I do not know the name of the internal table field
(say, "cust_id" in the above case) with which comparison is to be done in the WHERE clause. Only at runtime that fieldname is available. So in the WHERE clause can I mention it dynamically?
I tried using the following.
lv_fieldname = 'cust_id'.
SELECT kunnr INTO TABLE gt_kunnr
 FROM kna1
 FOR ALL ENTRIES IN gt_table
 WHERE kunnr = gt_table-(lv_fieldname).
But this is giving a syntax error.
Could anyone suggest an alternate approach?

Hmmm, you may want some NVL's around those case statements such as..
 and scheduled_date <= NVL(case when :check_value = 1 then date '2009-04-16' end,scheduled_date)
 and scheduled_date >= NVL(case when :check_value = 1 then date '2009-04-06' end,scheduled_date)
 and scheduled_date = NVL(case when not :check_value = 1 then date '2009-04-16' end,,scheduled_date)or some such thing. Otherwise the comparisons with Null will just cause it all to fail.

Be careful; post the code you're actually running.

My questions:
1) Why isn't the index t_indx used in Execution plan 1?To use an index, the indexed column must stand alone as one of the operands. If you had a function-based index on TRUNC (fdate), then it might be used in Query 1, because the left operand of = is TRUNC (fdate).
2) From the execution plan, I see that query 2 & 3 is better than query 1. I do not see any difference between execution plan 2 & 3. Which one is better?That depends on what you mean by "better".
If "better" means faster, you've already shown that one is about as good as the other.
Queries 2 and 3 are doing different things. Assuming the table stays the same, Query 2 may give different results every day, but the results of Query 3 will never change.
For clarity, I prefer:
WHERE fdate >= TRUNC (SYSDATE)
AND fdate < TRUNC (SYSDATE) + 1(or replace SYSDATE with a TO_DATE expression, depending on the requirements).
3) I read somewhere - "Always check the Access Predicates and Filter Predicates of Explain Plan carefully to determine which columns are contributing to a Range Scan and which columns are merely filtering the returned rows. Be sceptical if the same clause is shown in both."

Dynamic query in where clause while looping in an internal table.

Hi,
Had a small question : How can i make a dynamic query for the WHERE clause while looping at an internal table.
i want to implement a dynamic where clause query for the below example.
it_cfx_col is an internal table and wa_cfx_col is a work area for it_cfx_col
DATA :
i_cfx_col TYPE TABLE OF cfx_col,
wa_cfx_col LIKE LINE OF i_cfx_col.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
LOOP AT it_cfx_col INTO wa_cfx_col
WHERE CREATED_BY = l_name
AND SCENARIO = l_scenario.
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
Now i want to write a dynamic query for the where clause.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
l_where_clause = 'CREATED_BY = l_name'.
l_where_clause2 = 'AND SCENARIO = l_scenario'.
if l_scenario is not initial.
CONCATENATE l_where_clause l_where_clause2
INTO l_where_clause SEPARATED BY space.
endif.
LOOP AT i_cfx_col INTO wa_cfx_col
WHERE (l_where_clause).
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
when i compile this i get an error message as { Statement concluding with "...(l_where_clause)" ended unexpectedly}
Even i changed the initilization of the variable l_where_clause2 to [ l_where_clause2 = 'AND SCENARIO = l_scenario.'. ]
added the end of line demarkation ".", but still i got the same error message.
Is it a limtation in ABAP that i cannot write a dynamic query for the where clause while looping at an internal table?

Hi savita,
there in no such 1 limitaion in abap for dynamic query .. i think the error meassge is only beacuse of your synatx delcartaion.
>> LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE (l_where_clause).
   count = count + 1.
some business logic implemented using the work     area    wa_cfx_col
   endloop.
afted delclarataion also , in the where statement you should specify both the field name and value bname
   LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE l_where_clause = 'CREATED_BY = l_name' .
   count = count + 1.
hope it helps.

Values from a Multi-Select in the where clause of a Select statement

I have a web page that solicits query parameters from the user.
The selections that the user makes will populate the WHERE clause of a Select statement.
One of the controls on the page is a multi-select control.
When this page posts, I would like to execute a Select statement wherein the selected values from this control appear in the .. Column IN ( <list here> ) portion of the WHERE clause.
This is an extremely common scenario, but I cannot seem to locate a how-to or message thread that addresses this specific case.
I have an idea that it may involve dynamic SQL or Execute Immediate, but cannot seem to pin down the answer.
Any help would be greatly appreciated!
