I am using a view
select * from vw_pt_inv_customer
My requirement is have a web page where users can search for customers by filling in a form which has the following feilds: - User can fill in the form with all the feilds or not. I want a dynamic where clause.. how can i get this work for me?

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.

hi prabhu,
this is how u select dynamically...

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,
Jeroen van Veldhuizen

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.

Data Services Designer Query tranform dynamic where clause or another way

I have an XML source that has 5 fields. These fields are used to query 4 different SQL table data sources and do an AND inthe where clause of a query transform. Works well if all 5 fields in the xml have data. If one (or more) are blank, then it runs the where checking for blank matches and gives no results. What I want to do is if a field is blank, do not use it in the where clause. Could this be an outer join setup? Issue is that if there is a PhoneNumber input, then to be considered a result, there must be a PhoneNumber match on potential result records...

VPD - How to make the where clause a correlated query

Hi,
My VPD function has the following where clause:
where_clause:= ' project_id in (select object_id from pa_project_classes p'||
' where p.class_category='||''''||l_cat||''''||
' and p.CLASS_CODE='||''''||l_class||''''||
' and p.OBJECT_TYPE=''PA_PROJECTS'''||
The problem is that the subquery is not using the unique key defined on the table pa_project_classes. What I need is something as follows:
where_clause:= ' project_id in (select object_id from pa_project_classes p'||
' where p.class_category='||''''||l_cat||''''||
' and p.CLASS_CODE='||''''||l_class||''''||
' and p.OBJECT_TYPE=''PA_PROJECTS'''||
' and p.object_id=mainquery.project_id ||
The problem is that since the table pa_project_classes also has a column project_id, I have to prefix the column name by the alias of the main query like 'mainquery.project_id'. However this seems impossible as main query is not unknown .
I would be grateful if you could suggest any workaround or solution.
Thanks

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

Dynamic Where clause in 4.6C [Literals allowed but not variables]

Good afternoon-
We have a dynamic select statement that works perfectly in 4.7 ext 2, but is causing a short dump in 4.6C. The error in the short dump says:
The current ABAP/4 program attempted to execute an ABAP/4 Open SQL

HDR_COMP_CODE is in incoming parameter to the function module that is calling this code. It is of type BKPF-BUKRS.

Well, in this case, unless I'm missing something, you do not requre a dynamic WHERE clause. You can use RANGES instead.
report zrich_0001.

clear r_bukrs. refresh r_bukrs.
r_bukrs-sign = 'I'.

r_bukrs-low = hdr_comp_code.
append r_bukrs.

Setting dynamic WHERE clause in VO

Regards,

First make sure you have defined your method in the AM Impl class.
Here is a post from a few topics back :
umesh.agarwal wrote:
My question is how can I create a method that will return this information and use it from the ViewController ?For this:
1) Created a method in AMImpl
2) Exposed the method through Client Interface.
See this for more details:
http://docs.oracle.com/cd/E12839_01/web.1111/b31974/bcservices.htm#sm0212
Then
3) Define a method action binding in your jspx page(pagedef) where you want to access this method.
http://docs.oracle.com/cd/E15523_01/web.1111/b31974/web_adv.htm#ADFFD20984
4) Use the below code to call the AM method from View controller
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
OperationBinding operationBinding =
bindings.getOperationBinding("<method_name_in_AM>");
if (operationBinding != null) {
operationBinding.execute();
Object obj = operationBinding.getResult(); //obj will contain the value returned from your AM method
Step 4) is when you want to call that method from a bean.
You can also drag that method (from your data control) on your page. JDev will then ask if you want to make a form of it.
When you choose for that option, you will get an input field and a button. When you fill in the parameter in that input field and then hit the button, the method will be
executed and will use the inputed value as your parameter.

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:

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.

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.

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
