Pagination after executequery with a dynamic where clause

Hi all,
I have a problem with pagination after setting a where clause dynamically and performing an executequery in ViewObjectImpl.java.
As a result of this, the amount of records are decreased returned by the viewobject, however the pagination is not changed. It still reflects the previous amount. It changes only if you have selected the last range of the changed recordset
Does anybody know how to get the pagination to refect the correct amount of the updated recordset of the viewobject?

Thanks in advance, Erwin

Hi,
I would not add this to the VO query. Instead I would create a View Criteria that uses a bind variable. Then in the Application Module Data Model, you select the VO instance and choose edit (button on top) to permanently associate the view criteria)
Advantages of this approach
- The VO definition can be used elsewhere without the restriction
- the bind variable is not mandatory and yu can set it such that if no value is provided a full query is executed

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.

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

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.

Creating dynamic where clause with string delimiter " ; "

hi...
i need a solution for complex problem like, 1. start_date IN date,
end_date IN date,
shift_type IN varchar2
i will get shift_type as "first_shift" or "first_shift;second_shift" or "first_shift;second_shift;third_shift" ....etc any combination. where fist & second & third shits are nothing but 1 , 2 , 3. i need to find out data between start_date and end_date in combination of shifts ( may be 1;2 or 1;3 or 1;2;3 or 2;3 ...etc) . now i need to write this code in dynamic where clause ...i tried in different ways...but not succeeded. can anybody guide me step by step...or with script.
NOTE: there is a table called "shift" with data like
shift_type shift_mode
1 first_shift
2 second_shift
3 third_shift

Hi,
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
If the question involves parameters, give a few different sets of parameters and the results you want for each set, given the same sample data.
It's unclear that you need dynamic SQL at all.
If shift_type is a variable, that can be either a single value or a ;-delimited list (such as '1;3'), you can compare that to a column called shift_column like this:
WHERE ';' || shift_type || ';' LIKE
'%;' || shift_column || ';%'No dynamic SQL or PL/SQL required.
If you really do want to use dynamic SQL, these two pages should gives you some ideas:

Dynamic where clause with loop statement

Hi all,
is it possible to use a dynamic where clause with a loop statement?

Loop with dynamic where clause

hi,
In a program we need to use a loop into an internal table with a where condition is decided on run time.
"Select" from database table is using dynamic where clause and it is working fine.
For the loop part does any one have any idea on this? if we can have dynamic where clause in a loop into internal tab?
Thanks

Hi,
You can't use 'loop where' dynamically .
Have you already tried to use Ranges and CHECK statement?
Like:
First mount range options;
Loop at <table>.
Check using the range.
endloop.
Maybe it's works for you !!

REPORT with dynamic WHERE CLAUSE (run RDF or REP) ?

Hi:
When running a REPORT (myreport.rep) with dynamic where clause using a lexical parameter, I got this error:
REP-1439: Cannot compile .REP or .PLX file as it does not have source
If i run the report specifiying RDF extension (myreport.rdf) the report run successfully! Is this normal ?
If I specify RDF extension will Report Server COMPILE the report everytime I execute it ?
When using dynamic WHERE CLAUSE I will have to run RDF files instead of REP ?
I'm running Reports 9i under Linux, with IDS under Windows.
Waiting Help
Joao Oliveira

It sounds like you are building the .rep files on one platform (windows) and running them on another (linux). The reason that the .rdf file continues to work is that Reports recompiles the PL/SQL within the report when you move from one platform to another or change schemas. .rep files can't be re-compiled in this way so you need to ensure they are compiled successfully when converting them.
You need to convert from .rdf to .rep on the platform that you are intending to run on. Try running rwconverter on the linux platform with "compile_all=yes" to produce the .rep file and running that .rep file.

ADF dynamic where clause for VO query using BC

I'm hoping someone can help me out. I have a read only view object that I want to filter results based on some user choices. For example the user may want to see all results or they may only want to see a much smaller subset. This is for an error dashboard, the smaller subset maybe by application or maybe by application and by error severity. I think I can use a dynamic where clause but I'm not sure, Can someone get me started down the right path, or post an example that I can see.

Hi user,
You can use a dynamic where clause for this, but maybe there is a more practical option. Maybe you can have a fixed where clause, but using a bind parameter, like:
vo.application like :applicationParam. This makes an executeWithParams method available that you can call from your page, and use in the bindings. This parameter you can populate with the results of for example a poplist, with a default value of '%'.
When you do want to use a dynamic where clause, you will need to add a method to the java code of your application module, and make this method available for the client. In this method, you can use findViewObject to retrieve your VO, use VO.setWhereClause to set the whereclause to what you want, and then call VO.executeQuery. This method can then again be called from the page.
Success,

Passing values to Dynamic where clause as IN parameter - ADF

Hi,
I am trying to get the Dynamic where clause query output something like below,
select * from EMP where emp_id IN(200,203,204)
How to pass values from setWhereCluase(emp_id,????)
Thanks,

I'd go about this a little differently (probably not the best way):
1. Create view object lk_department (lookup). In the query add a union with something like "select null as ID, 'All' as name' from dual;". This adds a null value that they can select by leaving the combo box on "All". Add a 'order by id" so the null value is the first one. When creating the combo box you want it set to navigation mode, so select the whole viewobject from the data palette rather a specific field.
2. Create a jTextField for the "Jobs" field.
3. Create an application module method that does something like:
public void filterEmployees(String job){
ViewObject vo_departments = findViewObject("lk_departments");
ViewObject vo_employees = findViewObject("employees");
String wc = "1 = 1 ";
String wc = " and job like '%"+job+"%'"
if (vo_departments.getCurrentRow().getAttribute("Id") != null) {wc += "and department_id = "+vo_departments.getCurrentRow().getAttribute("Id");}
vo_employees.setWhereClause(wc);
vo_employees.executeQuery();
this.sync;
4. In your Jclient app, you just need to call the method of your appmodule and insert the string from the textbox, using code similar to this:
AppModule b = (AppModule)panelBinding.getApplicationModule();
b.filterEmployees(jTextField.getText());
I didn't test this code, but that's how I go about the same thing.

Dynamic where clause problem?

Hi all,
I am using 4 parameters for the attrition rate report of an employee on the selection screen.
Level
Grade
Position
Salary Range (pa0008-ansal)
i have filled the values of level, grade, position, from database tables at the initialization event.
And for the salary range i hardcoded them to 0-5000, 5001-10000 etc.. and so on.
and then showed all 4 parameters are listbox on the selection screen.
now the first 3 parameters are from infotype pa0001 and the last is from pa0008.
Now I want to select pernr, persg ,persk ,plans, begda ,endda fields from infotype pa0001, and 'ansal' field from pa0008 , with the help of a dynamic where clause, is it possible, because here it might be needed for a join as well.
Please help me out with some sample coding help.

<Added code tags>
Now in case of salary slab, i have ranges like 0-5000 , 5001-10000 and so on and I showed it as a listbox on sel. screen.
So how can I read the figure after the '-'?????
And also review, if for the previous 3 parameters it is correct, or it can be shortened and accurated.

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
where
case column_value
when 0
then value1
else
value2
end
this my query
SELECT ITMID as ItemId,
NVL(OrderDtl.PackageID, 0) PackageId,
OrderDtl.OrdDtlID,
(CASE NVL(OrderDtl.PackageID, 0)
WHEN 0
THEN 1
ELSE 0
END) as PackageFlag,
ivitem.Code ItemCode,
ivitem.ITMNAME AS itemName,

to_char(Issuedate, 'DD/MM/YYYY') IssueDate,
OrderDtl.OrdQty,

it is not working please someone help

About dynamic where clause

hi
on Jdev 11.1.2.3.0
Imade dynamic search (where clause)
It woks fine with me
but I want to be sure from the best way to do that
the ideia is to run search according to what is the user chose
on (Hr) schema employees table
the end user could search according to departmentID only
or job id only or both of them or display all employees taable data if there are no seletion
I used
this.setWhereClause( );
this.defineNamedWhereClauseParam();
this.setNamedWhereClauseParam();
methods in employeesImpl and I revale it to the client interface to display two text boxes and a button
my full code is
================
public void setwhereClause(String jobid ,String departmentId ) {
if (jobid==null & departmentId ==null) {
this.skipNamedWhereClauseParam ("P_DEPARTMENT_ID");
this.skipNamedWhereClauseParam("P_jobid");
this.setWhereClause("1=1");
this.executeQuery();
if (jobid==null & departmentId !=null) {
this.setWhereClause("EmployeesEo.DEPARTMENT_ID =:P_DEPARTMENT_ID");
this.defineNamedWhereClauseParam("P_DEPARTMENT_ID", null, null);
this.setNamedWhereClauseParam("P_DEPARTMENT_ID",departmentId );
this.skipNamedWhereClauseParam("P_jobid");
this.executeQuery();
if (jobid!=null & departmentId ==null) {
this.setWhereClause("EmployeesEo.JOB_ID=:P_jobid ");
this.defineNamedWhereClauseParam("P_jobid", null, null);
this.setNamedWhereClauseParam("P_jobid",jobid );
this.skipNamedWhereClauseParam ("P_DEPARTMENT_ID");
this.executeQuery();
if (jobid!=null & departmentId !=null)
this.setWhereClause( "EmployeesEo.JOB_ID=:P_jobid and EmployeesEo.DEPARTMENT_ID =:P_DEPARTMENT_ID " );
this.defineNamedWhereClauseParam("P_DEPARTMENT_ID", null, null);
this.setNamedWhereClauseParam("P_DEPARTMENT_ID",departmentId );
this.defineNamedWhereClauseParam("P_jobid", null, null);
this.setNamedWhereClauseParam("P_jobid",jobid );
this.executeQuery();
==========================================
but Iwas geting error when I run the search For the First Time only without selecting any thing
the error wase about ( attempt to define parameter which is not in the where clause)
one time for both variable if there are no selection
anothe for the P_DEPARTMENT_ID when I search for job
and the oposet for P_jobid when I search for department
so why this eror came despite of IF Statment existance
and why when I run search for both parameter job and departemnt
next time i search for all data or department only or job only
the error dosnot come again
Isuccesd to avoide this error by adding P_DEPARTMENT_ID and P_jobid
as bind varable in the same names for the employeesVo
note
(Idont want to use view Criteria for a segnificant reason)
and becasue Ineed to pass varaible to open a report_
in the same way user search_
and Ican't catch bindings for the view criteria_
my qusetions
1-Is what i Did is the correct way I mean adding the binde varable visicaly to SQL tab In the EmployeesVO
2- why is the error of ( attempt to define paramter not iexist in the where clause mainwhile the If Statment condition dosnot succesd)
3- how to add bindig variable programaticly without adding it phisicaly in the EmployeesVo SQL

Dynamic WHERE clause in SELECT statement

Hi,
I need to extract (SELECT) all the products in different salesorganizations. Since a product can be available in more than 1 salesorg I have created several properties in the PRODUCT dimension - 1 for each salesorganization (naming: Sxxxx where xxxx is the salesorganization number).
Since I need to prefix the salesorganization property with an "S" I have created a property on the SALESORG dimension called SALESORG.
Therefore I need to create a dynamic WHERE clause in the SELECT statement. Currently my script is:
*SELECT(%SORG%, "[SALESORG]",SALESORG, [ID]=%SALESORG_SET%)
*SELECT(%PROD%, "[ID]",PRODUCT, [%SORG%]="X")
My first SELECT find the Sxxx (equal to the property I need in the PRODUCT dimension). My second SELECT uses the variable in the first SELCT statement to use the correct property for the WHERE clause.
Unfortunately the code is not validated - any suggestions?
/Lars

Hi Lars,
If you run it from a DM package without validating it, does it still work? I would bet it does.
If this is the case I would open a message with SAP (it would be an enhancement request). Until they fix the validation code, you would just have to live with the script not validating.
Cheers,
Ethan

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.
