How to set dynamic WHERE clause to VO from backingBean?

Hi,
Can any one let me know the best way to add the dynamic WHERE clause in to VO query.
I have created AM (with AMImpl.java) & VO (with VOImpl.java & VORowImpl.java) in my model project. I suppose to set the WHERE condition at runtime while the user click the search button. I am handling the user button click at UI layer backingBean. From the backing bean I could able to get the objct of the VO and set the where clause by below code.
        ValueExpression valueExp = elFactory.createValueExpression(elContext, "#{bindings.UserSearchVO1Iterator}", Object.class);
        DCIteratorBinding dcIter = (DCIteratorBinding)valueExp.getValue(elContext);
        ViewObject userSearchVO = dcIter.getViewObject();
        userSearchVO.setWhereClause("lower(usr_login) LIKE ':1' and usr_udf_suid like ':2' ");
        userSearchVO.executeQuery();But as I fear this is not the right way to do it. So I am creating the cutom method inside the VOImpl.java and triggring that method by creating one more cutom method in AMImpl.java. But I dont know how to invoke this AM method from backingBean.
AMImpl method
public void initDetails()
        UserSearchVOImpl vo = getUserSearchVO1();
        vo.initQuery();
VOImpl method
    public void initQuery()
        setWhereClause("lower(usr_login) LIKE 'a%' and usr_udf_suid like '%1144%'");
        executeQuery();
    }Can any one guide me which is the best way to set the where clause to VO? How to call the AM method from backingBean?
Thanks

i am new to oracle 11g i writing a stored procedure in which i have made use of case in where clause to pass my parameter value v_toStoreID
i have googled a lot regarding that i found that to use case in where clause it should be like this

then value1
else
value2
end
this my query

How to create dynamic where clause instead of pragmatically

Hi,
I'm using Jdev 11.1.2.2.0 and my requirement to create a two fields with search button to fetch data as adf table. User need to enter either of the field value and click search button to see his data.
So I created a sql query based view object with 2 bind variables (which are input params) & 2 view criteria (to create dynamically where clause) and then drag on to the page by ExecuteWithParams operation from data controls but couldnt work.
If anyone have idea to build dynamically please let me know.
Amar

User need to enter either of the field value and click search button to see his data.User need to enter either of the field value and click search button to see his data.
Hi Amar,
Is your requirement, creating a query panel with table??
Drag and drop the view criteria(Application Navigator>DataControls> AppModule >NamedCriteria> ViewCriteriaName ) onto the page.
In the context menu, select Query->ADFQueryPanel With Table.. That brings your necessary two columns and Search field with data represented as a table.

How to set dynamic where clause in ADF?

Hi,
I have a View object called BillInfoVO. This has
all the information about who created the request, the time , status etc.,
I need to display this VO in a jsp. But before I display, i need to fileter this
VO results with different where clauses according to the role of the user.
For example, if the role is admin, then
where clause should be 'status = 'Completed, and created by = 'Current user'
If the role is requestor, then
the where clause should be
sales manager id = 'Current user' and
Status != Complete etc.,
Could any one please let me know how I can
dynamically set the where clause to filter the appropirate
result row set in the jsp?
Your help will be greatly appreciated.
Thanks,
venki

You'll create a service method in your AM that will use the setWhereClause method of a viewobject.
Then you'll expose it as a client method.
Then you'll drag it from your data-control onto a button in your JSF page that will call your page for the query.
More about service methods here:

Dynamic Where Clause in SQR

How to construct dynamic WHERE clause in our sqr programming ?
In my run control table I am having parameters fromdate, thrudate [mandatory parameters] and location as [Optional Parameter] how can I declare dynamic where clause to achieve this could any one help me with coding ? Here is my sample coding
Begin-Procedure Main
if $prcs_process_instance=' '
do askvalues
else
do getvalues
end-if
End_Procedure Main
Begin-Procedure askvalues
input $frmdate 'Enter From Id' type=text format=number !Mandatory Parameter
input $todate 'Enter To Id' type=text format=number !Mandatory Parameter
input $loc 'Enter Location' value=text !Optional Parameter
End-Procedure
Begin-Procedure getvalues
Begin-Select
FROMDATE
THRUDATE
SQR_LOCATION
let $frmdate=&FROMDATE
let $todate=&THRUDATE
let $loc=&SQR_LOCATION
let where=-------------------------- ?
FROM
PS_PROCESS_TBL WHERE OPRID=$PRCS_OPRID AND RUN_CNTL_ID=$PRCS_RUN_CNTL_ID
End-Select
End-Procedure getvalues
Begin-Procedure selectall
BEGIN-SELECT
SQR_EMPLID
SQR_FNAME
SQR_LNAME
SALARY
FROM
PS_SQR_FIRST_TBL WHERE SQREMPID BETWEEN $frmdate AND $todate
END-SELECT
End-Procedure selectall

SQR will understand Where Clause as dynamic, when you include it in Square Brackets []
In your case, since fromdate & thrudate are mandatory values, I would code like this
let $frmdate=&FROMDATE
let $todate=&THRUDATE
let $loc=&SQR_LOCATION
let $Where_Clause = 'SQREMPID BETWEEN' || ' ' || $frmdate || ' ' || 'AND' || ' ' ||$todate
if $loc != ''
let $Where_Clause = $Where_Clause || ' '|| 'AND' || ' ' || 'LOCATION = ' || $loc
end-if
Now you can use this Dynamic Where Clause in which procedure you want. Only thing is you need to encode the where clause with brackets([$Where_Clause])

Dynamic where clause for generated reports (designer 6.0)

Hi,
I'd like to include dynamic where clause into my reports. It's easy with report builder by using bind parameter in a query where clause (&param where param is a parameter in which you fill a VARACHAR2 to complete default where clause).
Problem with designer 6.0 report generator is that he failed while trying to parse the query statement he contructs if there is a bind parameter within.
How can I manage this problem ?
Thanks for answers
Romain

Hi Divya,
     SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,'paramform=no P_WHERE_CLAUSE= '||Where_Clause);Instead of using SET_REPORT_OBJECT_PROPERTY built in try using ADD_PARAMETER built in which
adds parameters to a parameter list. Each parameter consists of a key, its type, and an associated value.
v_rep := RUN_REPORT_OBJECT(repid); and instead of using RUN_REPORT_OBJECT try using RUN_PRODUCT.
DECLARE
     repid REPORT_OBJECT;
     v_rep VARCHAR2(100);
     Where_Clause Varchar2(4000) := null ;
        *Pl_Id        ParamList;*
        *Pl_Name      VARCHAR2(10) := 'param_list';*
BEGIN
     Where_Clause := 'Where '||Create_Where_Clause();
     message(Where_Clause);
     message(' ');
        pl_id := Get_Parameter_List(pl_name);
        IF not Id_Null(pl_id) THEN
           Destroy_Parameter_List(pl_id);
        END IF;
        pl_id := Create_Parameter_List(pl_name);
        Add_Parameter(pl_id,'P_WHERE_CLAUSE', TEXT_PARAMETER, WHERE_CLAUSE);
        Add_Parameter(pl_id,'PARAMFORM',TEXT_PARAMETER,'NO');
--      Add_Parameter(pl_id,'ANY_OTHER_PARAMETER', TEXT_PARAMETER, 'VALUE FOR OTHER PARAMETER');
        RUN_PRODUCT(REPORTS,'REPORT_NAME', ASYNCHRONOUS, RUNTIME, FILESYSTEM, pl_id, NULL);
END;Also you can add as many User created or System parameters as you want using add_parameter. Updated the code to add PARAMFORM parameter.

How to add a dynamic where clause for a sql based VO with group by query?

Hi,
Here is my case, I have a sql query based VO with the query like "select status, count(*) StatusCount from my_table group by status". Now I used the following java code trying to dynamically add the where clause to my VO to filter the rows based the type attribute in my DB table.
vo.setWhereClause("type='MyType1' ");
vo.executeQuery();
Then I got the sql syntax error. Looks like the ADF has added the where clause to the end of my sql so my sql becomes "select status, count(*) StatusCount from my_table group by status where type='MyType1' ". But what I expected was the correct syntax "select status, count(*) StatusCount from my_table where type='MyType1' group by status".
Does anyone know if this is an ADF bug? Or is there any other way to achieve my goal?
Thanks,
Chunyang
Edited by: Chunyang on Dec 13, 2012 9:09 PM

Hi,
When you use setWhereClause on the VO, it is applied on top of the VO query. I.e, assume your VO has the following query.
select empno, ename from empNow, if you apply the where clause programatically, only the two attributes that you are using in the select statement could be used. I.e
select * from (select empno, ename from emp) where ename='KING' - VALID
select * from (select empno, ename from emp) where deptno=10 - INVALID (because the inner query - the one you've defined as query for your vo does not have deptno attribute selected)If you would need to set a dynamic where clause, you need to make them available in your select statement / use bind variables.

How to create VO with multiple dynamic where clauses on select with UNION?

I am trying to implement the View Object for the UNION query that looks like this:
     select a,b,c...
          from t1,t2,...
          where dynamic_where_clause1
     union all
     select a,b,c,...
          from t11,t12, ...
          where dynamic_where_clause2
There are up to 60 input parameters that are used to generate dynamic where clauses. They are actually created by calling PL SQL function.
So far, I was not able to assign both where clauses to the view object. Is there a workable solution for this problem, besides resorting to programmatic View Object?
I understand that recommended way with UNIONs is to wrap both queries into a parent select:
select * from (
     select a,b,c...
          from t1,t2,...
          where ... -- table relationship joints
     union all
     select a,b,c,...
          from t11,t12, ...
          where ... -- table relationship joints
) QRSLT
     where dynamic_where_clause
Unfortunately this approach doesn't work here, since individual selects are producing unmanageable amount of data and resulting query takes forever to complete.

I afraid I would not have any real benefits from using VO if I replace the entire query with every request. Actually, the performance may suffer.
I solved the problem by creating a POJO Data Control and invoking the custom select query from java. Not sure if it is the best approach to the problem, but implementation time is limited and it works.
Actually, this is not the first time I see the need to implement VO with complicated SQL like select with unions and dynamic pieces. It would be nice to find a solution and not resort to workarounds.

Dynamic Where Clause - How To?

I need help building a dynamic where clause in 1.6
I have three fields:
p1_col_where which is a static list of 8 columns
p1_condition which is a static list of the 9 possible conditions(=,<,>...)
p1_condition_value is a text field that the user enters the literal they want to use
The lov select I thought would be:
SELECT Description, positem
FROM v_item
WHERE :P1_COL_WHERE :P1_CONDITION :P1_CONDITION_VALUE
I was hoping that this would be resolved to: WHERE item = 123
but of course I get a big NASTY error.
Can someone help me out?
Thanks,
Joe

Mike,
Thanks for the help.
There's a problem in the docs for creating this popup on step 5. The docs say:
Step 5 - Add the LOV report to the popup page
select ename, job, sal , 'placeholder' the_link
from emp
where ename like '%'||:P2_ENAME||'%'
and (job = :P2_JOB or :P2_JOB is null)
and (sal = :P2_SAL or :P2_SAL is null)
Note that the last column in this query is just a placeholder. once the region is created, turn that placeholder into a link by doing the following:
1.     Navigate to the Page Definition for page 2
2.     Next to the name of the report region created in step 5, Click Q
3.     Next to the column THE_LINK, click the edit icon
4.     In the "Link Text" field enter the string "select"
5.     In the URL field enter: javascript:passBack('#ENAME#','#JOB#','#SAL#');
6.     Click the "Apply Changes" button
The problem is in number 5. There is NO URL field to enter that code. Where does it go?
Also, your alternative method:
IF :P1_COL_WHERE is null then
RETURN 'SELECT Description, positem FROM v_item';
ELSE
RETURN 'SELECT Description, positem FROM v_item '||
' WHERE '||:P1_COL_WHERE||' '||:P1_CONDITION||' '||:P1_CONDITION_VALUE;
END IF;
With a 'GO' button is the method that I was trying. That's what gave me the error when the page loaded.
Any assistance is greatly appreciated.
Thanks,
Joe

How to set the where clause of a value set on the basis of a form field

I am using a DFF(Descriptive FlexField), which needs to display the value of a certain column(say columnA) on the basis of the value of another column(say columnB).
So i have created a value set which points to the table which has both these columns, and the DFF uses this value set. However, the problem is that I have not put any where clause in the value set, because of which i cannot handle the exact fetch returns more than one rows error.
The query has to be as follows:
select ColumnA from tbl where ColumnB = [ a form value ];
What I want to know is how can i get the value of a certain field of a certain block of the form in the above query.

Just have a look over these two statements if it solves your problem
one time where clause
Set_Block_Property('BLOCK_NAME',ONETIME_WHERE,your form item);
dynamic where clause
set_block_property('BLOCK_NAME'default_where, your form itme)
you can where clause at run time from any procedure or some triggers

And having an open ended search function on a web page is also not a great idea.
If you are using Apex, the for performance (and even query flexibility) it will be better creating a separate reporting region for each unique query. A boolean rendering condition checks the existing bind variables in order to determine if that specific reporting region should be executed.
This results in a reporting region having a proper and dedicated SQL query (no hacking of the where clause) and that region only being rendered for the proper combination of supplied filter criteria.
A slightly more complex, but more flexible approach, is using a generic reporting region that calls a PL/SQL function that creates returns the SQL query for execution and rendering. The approach to this is very similar to constructing a SQL ref cursor (dynamically) for a client. The only difference is that instead of creating the actual ref cursor, the code simply needs to return the SQL source code statement - with bind variables. The Apex run-time does the rest (does the binds and execution and rendering).
If you are not using Apex - you should still consider these approaches. And not hacking a single SQL to cater for all different types of filter conditions.

Dynamic where clause in select query

Hi
I'm trying for a dynamic query and in the dynamic where clause i'm checking a field for constant.....for instance if i wanna to use WERKS EQ '0478' how to declare it in dync where clause. i tried for the following:
SELECT (TAB_FIELD) INTO TABLE DITAB UP TO 10 ROWS FROM (TAB_NAME) WHERE (CONDI).
heree CONDI = 'werks eq 0287' . in this case the query fails as the werks shud be equal to '0287' and not just 0287. How to handle this? i tried for the following
CONDI = 'werks eq " '0287' " ' but no luck as it is not a valid stmt as i knew.

Dynamic WHERE Clause in a Calendar

I would like to have a Calendar display values based on a dynamic WHERE clause created using PL/SQL anonymous block evaluating the values of items that the user uses as filters. I have done this dynamic SQL for reports and would lke to do the same for a Calendar.

I figured out how to do this.
I created a Hidden Item with the source value of &APP_USER.
named P50_APP_USER.
This is how my query looks now:
SELECT * FROM APX_EVENT WHERE APX_EVENT.STORE_NR IN (SELECT APX_Z.STORE_NR FROM APX_Z WHERE APX_Z.USERNAME = :P50_APP_USER)
And it works.
I got the answer from this thread:

Dynamic where clause in Loop

Is iot possible to use a dynamic where clause in a loop? If so how to you code this?
i.e. Loop at itab in wa where (dynamic_where_clause)...
    endloop...
Moderator message: please read ABAP documentation for your SAP release.
Edited by: Thomas Zloch on Mar 29, 2011 3:20 PM

You should be aware that a LOOP AT ... WHERE is not an optimized access .
+ because on a standard table there is not sort order,
   so the loop goes over the whole table and does
   something when the condition is fulfilled
+ it is optimzed for sorted tables, but only for one key!
=> so your idea must have bad performance!
If this is not a problem, then you can solve the problem
in the following way:
loop at table
   if ( dynamic condition )
   endif.
endloop.
But maybe is dynamic condition is not necessary, but
a some fixed if-conditions are also o.k.
