Query in bc4j view object?

I am creating a vo based on employees table(hr demo schema) . It has managerid column , i want to display manager name instead of managerid. So in my view object i want
Employees : FirstNAme, Lastname, email and managername.
How to do a query like ' select firstname from employee where employeeid= 100' . (which is current employees managerid) in the vo.??
So that managerid gets converted to managername for each employee.

Dhiraj,
I would add the manager name and have the manager id as a hidden filed in your application. Set attribute property in display hints to display hide. This way the manager id is present but not shown.

Changing the query on a view object

I have a view object right now, based on an entity. It is the default view object, so that means the query in the view object is straight forward, it grabs all of the attributes from the table. And there is no WHERE clause.
In reality I only want to show a finite set of rows from my table. Every time a record is changed/edited in this entity and committed, a new row in the database is created with the same information (I'm using CreateWithParams) except for a few columns.
I actually don't really have update on this table, just creation of new rows. But to the user, I want it to 'look' like they are editing something in the table.
Example:
12, 11:32,Thompson, 60 (the user edits this information in an adf table, and a new row is created in the db)
12, 11:55, Thompson, 75
I have a timestamp (see above) field in the database that is used as part of my primary key, so that I know which record is the latest.
When the VO query is run, I want the user to only see the latest row from the db.
12, 11:55, Thompson, 75
So...
I went to my VO, and I changed the WHERE query to add this:
where t1.TimeStamp = (Select MAX(t2.TimeStamp) FROM rcl.x t2 where t1.uid = t2.uid);
Now, this isn't a mysql/sql question. There's actually a better query that I'd rather run, but the VO editor doesn't allow me to change the query itself....
When I save the new WHERE to my VO, run my page again, I get the expected result (showing me only the latest records).
However, when I try and sort on the table in which my data is displayed, I am now getting ORDER BY errors.
I don't want my VO to be read-only sql based. I want to be able to update my table, so I have my VO running off of the entity.
Why doesn't the VO allow me to change the query itself? (Like do a subquery, instead of having my where clause do the work)
Why are order by errors being thrown when I sort on my adf table after changing the where clause in my view?
Hopefully I wasn't too convoluted in the explanation of my problem..
Thanks in advance,
Joel

HI Joe,
Regarding your problem you can do one of the following tasks:
1- easily to tuning on your view object, I mean in the tuning page of the view you can set that only return 1 record or 2-3 record fetch not all the record.
in the order by you will order by the timestamp field and descending.
2- you can order by the timestamp descending and in the where clause only set the rownum<2 (will return the last record) you can also set rownum<5 and get the 4 last record etc.
3-editing the view query in the expert mode is not advised at all because of many consequences that you will face.
4- maybe it is not bat that you add a readonly view for the table you mentioned and every time you unpdate the entity just re-execute the read-only view.( this method maybe is good maybe is not it depends on your business logic)
Regards.

BC4J view objects on pipeline functions

Hello,
I just wanted to find out if we can place a BC4J view object on the new Oracle 9i Pipeline functions.
Thanks
Ramna

If it still looks on the outside like a database view to the JDBC client (BC4J in this case), then sure.
If you're making updates, then your underlying entity object will have to:
[list]
[*]Be mapped to an appropriate, updateable table, or
[*]Write INSTEAD OF triggers for your view
[list]
Let us know if you hit any problems.

Passing an argument in the SQL Query of a View Object

Hi,
It is possible that this question has been asked before, however I have searched for a half an hour in the forums and couldn't find a solution.
I am also new to using JDeveloper and ADF. Here's the situation:
I am developing an application that doesn't have to do anything else then displaying data from a database. Pretty straightforward actually.
Now I have made a vew pages with several collapsible panels (af:showDetailHeader) and have setup the datasources (or so I thought).
All that remains is:
- drag & drop a view object, from the application module that I created, onto the collabsible panels, so a child element gets created which displays data from the database.
- hack the layout so it looks like I want it to.
The problem that I have is the following:
I am using a 'User'-class that contains values I need when quering the database.
That User-object is part of a user-session.
What I want, for example, is to use the 'getPersonId()' function of that User-object and pass the argument to a SQL-query of a certain view-object.
The query would become something like:
'SELECT * FROM people WHERE people.personId = :someNumber'.
Now I've read some stuff about variable binding, which is complemented by something like (backing bean code):
getDBTransaction().getRootApplicationModule().getACertainViewObject().setWhereClauseParameter(1, user.getPersonId());
The examples I have found that might match my wishes are not using business components, but EJB's. I am having difficulty with understanding the 'how'-part of variable binding.
Also, I do not know enough of ADF to be able to create a situation like:
'User loads page, collapsible panel 1 is fully shown, the others are undisclosed.'
(meaning, that for panel1 a query has been executed.)
'User clicks on collapsible panel 2 which triggers a backingbean that somehow retrieves data from a view object'.
I would appreciate any help that somebody can give.
If it is not too much of a problem, please provide code snippets in case you have a solution. I am new to ADF :(.
-edit
I am using JDeveloper 10.1.3.3.0 in case that is of any importance.

Hello Stijn,
I didn't think about a referenced bean rule in the faces-config.
I added it right away and I am now able to set parameters of a View-object, not using a page button and before the page loads. You made my day!
In case anyone ever reads this post again, the summary of how to generate a table based on a View-object using dynamic parameters.:
1a: Go to faces-config.xml -> Overview tab'
1b: Go to the menuitem "Referenced Beans"
1c: Click on 'new' and select the existing bean you want to access data from and input a name. In this example I use name="user"
2: Create a View-object using the wizard.
2a: Specify the query you want in the menuitem 'SQL Statement'.
Add the 'parameters' you want to. You will have something like:
"SELECT * FROM someTable WHERE table.columnname LIKE :someArgument".
- hint: if you want the result to become something like:
"SELECT * FROM someTable WHERE table.columnname LIKE '%someArgument%'" then you have to add the '%'-characters in your code itself (read: someClass.setParameter("%" + someArgument);).
2b: In the menuitem 'Bind Variables' you have to add the variables you are referring to in the query. If you look at the query in 2a, then you have to add a variable with name "someArgument".
2c: Add the View-object to a Application Module (create one if nessecairy).
3a: Open a .jsp(x) file. Drag the View-object created in step 2 from the 'Data Controls'-pane to the page.
3b: Click on the '+' of the View-object in the 'Data Controls'-pane and open 'Operations' and drag 'ExecuteWithParams' to your page as a button.
3c: We do not want to use a button, the action has to be executed immediatly. So In the page source remove the lines that were created after dropping 'ExecuteWithParams'.
3d: Right-click on the page and select "Go to Page Definition".
3e: Go to the action id that is called 'ExecuteWithParams#', where # is a number.
Change the id to something useful.
3f: Change the NDValue so it corresponds with the value you want.
Example:
<action id="getAddressData" IterBinding="AddressesView1Iterator"
InstanceName="MyHRServiceModuleDataControl.AddressView1"
DataControl="MyHRServiceModuleDataControl" RequiresUpdateModel="true" Action="95">
<NamedData NDName="someArgument" NDType="java.lang.String"
NDValue="#{user.personId}"/>
</action>
Note: It is possible to use the value of a Backing Bean in NDValue.
Note 2: user is the bean I referred to in the faces-config.xml!
3g: Under the executables item, add an 'invokeAction' to pass the parameter to the View-object before your JSP-file loads:
<executables>
<invokeAction Binds="getAddressData"
id="loadAddressDataOfPersonIdInSession"
Refresh="prepareModel"/>
Thank Stijn Haus for this :)

Issue in attaching dynamic Query to the View Object

Hi,
We are having a View Object attached to the JRAD page.
The View object is build thru as Expert mode. There is no any CDATA
SQLQUERY stored in the VO.xml file.
We are building the query dynamically and attaching it to the VO in
RUNTIME.
The code is as below
// getFcstQuery() is method used to return the dynamic query
String query = getFcstQuery();
// Setting the Query to View Object
getViewDef().setQuery(query);
setQuery(query);
The JRAD page has sorting option on 5 columns. so when a sorting is
done the data are interchanged between the clients.
For example how the query will be build id
Say for the first user the query will be as
"select ename,eno,dno from emp where eno=1 "
for the second user the query may be
"select ename,eno,dno from emp where eno=2 "
Now if both the user hit the sorting on any of the column the data is
interchagned between this both users.
Please provide solution if possible.
Thanks in advance

Hi Steve,
We are using 5 tables in building the query.
Say,
1) summary
2) transactions
3) transactions_history
4) rules
5) rules_temp
but only 2 tables are used at a time
for read only we are using
summary table
for edit only mode we are using
1) transactions and
2) rules
tables
for edit and recalculate mode we are using
1) transactions and
2) rules_temp
tables
for one more condition we are using
1) transactions_history and
2) rules
tables
From all the above combination we are getting 5 columns. All the columns are defined the above combination tables. So using the same region. based on the conditions the combination of tables will change.
Becoz of this we are building the query dynamically.
Thanks
Balamohan

Inserting a new row in a BC4J View Object with an attribute of type BFileDomain

Hi all,
I've to insert a row in a View Object with an attribute of type oracle.jbo.domain.BFileDomain.
I do this within an Application Module's method, which has an input parameter of type byte[]. This parameter will be the content of the BFILE.
What's the right way for doing that?
I've tried with the following code, but I've got an exception in committing the transaction:
public int serializeDocument(int codDomanda, int codSorgente, byte[] content, String est, int type, int cost, String title, String arg) throws JboException {
int code = 0;
//File f;
DocumentiTwoView = getDocumentiTwoView();
java.sql.Statement stmt = ((DBTransaction) getTransaction()).createStatement(1);
try {
Row docRow = DocumentiTwoView.createRow();
SequenceImpl seq = new SequenceImpl("documenti_seq", getDBTransaction());
Integer next = (Integer) seq.getData();
code = next.intValue();
docRow.setAttribute("Coddocumento", new Number(code));
docRow.setAttribute("Titolo", (String) title);
docRow.setAttribute("Argomento", (String) arg);
docRow.setAttribute("Costo", new Number(cost));
docRow.setAttribute("Tipo", new Number(type));
docRow.setAttribute("Coddomanda", new Number(codDomanda));
docRow.setAttribute("Codsorgente", new Number(codSorgente));
//f = new File("Doc" + code + "." + est)
BFILE src_lob = null;
ResultSet rset = null;
rset = stmt.executeQuery ("SELECT BFILENAME('DOC_DIR', 'Doc" + code + "." + est + "') FROM DUAL");
if (rset.next()) {
src_lob = ((OracleResultSet)rset).getBFILE(1);
BFileDomain bfd = new BFileDomain(src_lob);
bfd.setBytes(content);
bfd.saveToDatabase(getTransaction());
docRow.setAttribute("Contenuto", (BFileDomain) bfd);
catch (Exception ex) {
getTransaction().rollback();
throw new oracle.jbo.JboException("Impossibile creare il nuovo documento:\n" + ex.getMessage());
finally {
try {
stmt.close();
catch (Exception nex) {
try {
// Commit the whole transaction
getTransaction().commit();
catch (Exception e) {
e.printStackTrace();
getTransaction().rollback();
throw new JboException("Impossibile eseguire il commit della transazione:\n" + e.getMessage());
return code;
Thanks a lot in advance!

Odd, have you disabled caching and indirection? (NoIdentityMap, dontUseIndirection, or alwaysRefresh/disableCacheHits). If so, then this could be the issue.
Otherwise please include the sample code you use to perform this, and verify that you do not have any unusual code in your set/get methods or in descriptor events. Also turn TopLink logging on and include a sample. Also ensure that you do not modify your objects until after registering them in the unit of work, and only modify the unit of work clones.

How to set query for child View Object?

I have a hGrid in standard page. Two View Objects are present connected using view link. I need to set where clause in the child View Object. The changes are not getting reflected when i set the where clause. Also when i try to fetch rowCount it returns 0 for child View Object. But i am able to get the value for parent View Object. Any suggestions please.

Hi,
This solution worked for me last time, Please create One blank row and delete that row(For Child VO).
Why we are doing this? : Because the child vo pointer might not init. See this is not our fault, this is because of OA Framework. But this works for me :)
Thanks,

Spatial Query on ADFBC View Object

Hello,
I'm in the process of migrating some Oracle Forms modules to JDeveloper and I've hit a snag with a query that uses MDSYS.SDO_WITHIN_DISTANCE to find all records within X kilometers from a line which is composed of an undefined set of waypoints.
eg.
Table:
HOTELS
Columns:
ID (Integer)
NAME (Varchar2)
ADDRESS (Varchar2)
LOCATION (Sdo_Geomery - latlong point)
Query:
SELECT *
FROM hotels
WHERE
mdsys.sdo_within_distance (
location,
mdsys.sdo_geometry (
2002,
8307,
null,
mdsys.sdo_elem_info_array (1, 2, 1),
mdsys.sdo_ordinate_array ( 9.45, -39.54, 10, -40.23, ...., .... )
'DISTANCE=7.5 UNIT=KM'
) = 'TRUE';
The SDO_ORDINATE_ARRAY needs to be passed an unknown number of values for the latitude and longitudes to define the line.
The current Oracle Forms module uses a pre-query trigger to dynamically build and apply the entire where clause, concatinating all the supplied values for the line co-ordintates.
I'm now trying to work out what the best way would be to implement this style of query with ADF BC VOs and ADF/JSF pages. If someone has done this already, any guidance on how this can be done would be greatly appreciated.
Thanks,
Michael.

You can use the setWhereClause built-in method on your VO to create the where clause dynamically here too.

Decode statement in Select line of a View Object Query

I attempted to create a view object in expert mode with a customized query.
The query had a decode statement in the select line of the query. The view
object compiled correctly but gave an error when run.
ex: select .... decode(CrpSchools.SCHOOLS_ID,null,CrpCustSchools.SCHOOL_NAME,CrpSchools.SCHOOL_NAME) SCHOOL_VALUE, ...
from ....
where ....
The error was that school_value does not exist in the statement. I got the error when
doing a vo.executeQuery().
When I removed the decode statement everything worked correctly. Does anyone know if
the decode statement cannont be used in the select line of a query in a view object?
Or maybe I was linking the query column (SCHOOLS_ID) up to the view attribute (SCHOOL_VALUE) incorrectly in the
Attribute Mappings tab of the VO wizard?

There should be no problem using a DECODE() statement, provided that you've aliases the column as you have done.
At design time, if you click on the (Test) button, does your query test ok?
Are you by chance applying a custom where clause at runtime?
If so, are you saying:
setWhereClause("yourtable.column_alias = ?";
or are you doing:
setWhereClause("column_alias = ?";
for an expert-mode query, you'll need to use the latter syntax.

How To change the ADF View Object query where-clause at RunTime?

I am trying to create a simple display page which will display user data (username, assoc_dist_id, assoc_agent_id, status , etc). The User data is stored in a database table and i am using an ADF Read Only table based on the View Object to display the data on the JSF page.
However, i want to display only the users that a particular person accessing the page has the AUTH LEVEL to see. e.g. If the person accessing the page is an 'ApplicationAdministrator' then the page should display all users in the table, If its a 'DistributorAdministrator' then the page should display only users associated with that Distributor (i.e. assoc_dist_id = :p_Dist_id ) and If its an 'AgentAdministrator' , then the page should display only users associated with that Agent ( i.e. assoc_agent_id = :p_Agent_id).
Currently my af:table component displays all the users in the table because the query for the view object is (select * from users) . However, i want to use the same viewobject and just set the where-clause at runtime with the appropriate parameter to restrict the dataset returned.
Do anyone knows how to accomplish this ?

David,
See the custom method initializeDynamicVariableDefaults() in the SRViewObjectImpl.java class in the FrameworkExtentions project in the SRDemoSampleADFBC sample application. You can find out how to install the demo if you haven't already from the ADF Learning Center at:
http://www.oracle.com/technology/products/adf/learnadf.html
This class is a framework extension class for view objects that adds a neat, generic feature to be able to dynamic default the value of named bind variables. You can read more about what framework extension classes are and how to use them in Chapter 25, "Advanced Business Components Techniques" of the ADF Developer's Guide for Forms/4GL Developers, also available at the learning center above.
It is an example of generic framework functionality that "kicks in" based on the presence of custom metadata properties on a named bind variable. See section 25.3.3 "Implementing Generic Functionality Driven by Custom Properties" in the dev guide for more details. Using this sample code, if you add a bind variable to a view object, and define a custom metadata property named "DynamicDefaultValue" on that bind variable, and set this custom metadata property to the value "CurrentUser", then that bind variable will have its value dynamically defaulted to the name of the authenticated user logged in. If instead you set this custom property to the value "UserRole", then the bind variable will be set to the comma-separated string containing the list of roles that the authenticated user is part of.
Once you've created a framework extension class for view objects like this, you can have the view objects you create inherit this generic functionality.See section 25.1.4 "How to Base an ADF Component on a Framework Extension Class" in the dev guide for more info on this.
By adapting a technique like this (or some idea similar that better suits your needs) you can have your view object query contain bind variables whose values automatically take on the defaults based on something in the user-session environment.

How do I query changed view object attribute in another view object

Jdeveloper 10.1.3.4
My requirement is that I want to be able to query a view object (based on entity) on a non-key attribute where the value I am searching on may either be in the database on an existing record or, have just been recorded by updating a different view object based on the same entity (and yet to be committed).
When querying the second view object for a value just updated via a different view object, the second view object always returns no rows. I had expected the process to be :
EntityA
ViewObjectA based on EntityA
ViewObjectB based on EntityA
ViewObjectA - query row with key = 123. update attribute Y with value 456 (attribute Y in database null). Entity cache for EntityA, key 123, atttribute Y updated with value 456
ViewObjectB - query row with attribute = Y. expect record in EntityA cache just updated to be returned. Instead, nothing is returned
Here is the code I was using (where RandScheduleEdit and RandScheduleSearch are identical view objects based on entity object RandSchedule)
public static void main(String[] args) {
    String        amDef = "test.cache.model.AppModule";
    String        config = "AppModuleLocal";
    ApplicationModule am = Configuration.createRootApplicationModule(amDef,config);
    ViewObject rsEdit = am.findViewObject("RandScheduleEdit");
    Key rsKey = new Key(new Object[]{40});
    Row[] rsEditRows = rsEdit.findByKey(rsKey,1);
    Row rsEditRow = rsEditRows[0];
    rsEditRow.setAttribute("SId", new Number(7827));
    ViewObject rsSearch = am.findViewObject("RandScheduleSearch");
    rsSearch.setWhereClause("S_ID = :SId");
    rsSearch.defineNamedWhereClauseParam("SId", null, null);
    rsSearch.setNamedWhereClauseParam("SId",new Number(7827));
    rsSearch.executeQuery();
    Row rsSearchRow = rsSearch.first();
    Configuration.releaseRootApplicationModule(am, true);
}Why does rsSearch not find the record S_ID = 7827 ? It seems to only be querying new records in the database and ignoring the cached record just updated ?
Any help greatly appreciated.
Cheers,
Brent

rsSearch.setNamedWhereClauseParam("SId",new Number(7827));This might help:
rsSearch.setQueryMode(ViewObject.QUERY_MODE_SCAN_ENTITY_ROWS);
rsSearch.executeQuery();

Query through bc4j

I have a bc4j view object querying 4 tables. The same query running in, say, sqlplus can produce some 5000 results. But tested through the application module, I can not get any row (no error message). Is it reasonable, or anything might be incorrect here?
Thanks,
Song

Thanks Steven!
I found that there was an error in the view link I used to approach the view. That being fixed, now the view works fine.
Thanks for your attention and prompt reply.

Expert Mode of View Objects

Hi!
Whenever I try to execute my query in expert mode,
I'll receive an "INVALID COLUMN" exception.
FYI: I add a regular, valid expression to my where-clause in a public method of my view object implementation (using setWhereClause or addWhereClause).
Looking at the debug output I realized that BC4J constructs the following invalid statement at runtime:
SELECT * FROM (SELECT ....)
This is really strange, because within the view object wizard everything works fine.
Does anyone have any idea how to solve this (using JDev 9.0.3.3)?

Two questions.
1. Do you get a "valid query" response when you check the query in the view object dialog?
2. Can you post the .addWhereClause() statement you are using in addition to the query itself?
I have gotten the "invalid column" message before when I was adding a where clause programatically due to the naming of the column. More specifically, in my case, I was providing the column name I set up in the view object but it needed a specific format. I believe it was "getColumnNameForQuery()" function of an attribute iterate object in JSP but I'm sure the format is the same.
The format ended up being the table alias defined in the query and the column name uppercase. EG.
SELECT THISCOLUMN
FROM THIS_TABLE THISTABLE
the query format was THISTABLE.THISCOLUMN
Hope this helps!

Problem while Binding multiple Parameters to View Object[Solved]

Hello,
I am facing problem while binding multiple parameters with different data types in View Object query. For example suppose I have following query in my view object.
SELECT Header.ADDED_BY
Header.BATCH_ID,
FROM BATCH_HEADER Header
WHERE :1='deptAdmin' and Header.BATCH_ID
in
select batch_id from batch_header_dept_mapping where dept_id in(SELECT * FROM TABLE(CAST(:0 AS TABLE_OF_VARCHAR)))
I am able to pass the Bind variables of Array type for : 0 , using Steve's ArrayOfStringDomain example. (ArrayOfStringDomain) .
But after passing value to second bind parameter ie.. :1 .
I am getting the error as follows.
## Detail 0 ##
java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected - got CHAR.
I tried to set
setWhereClauseParam(1,11); // 11 is Number
setWhereClauseParam(0,arr); // arr is arr = new Array(descriptor,conn,deptid); for in parameter.
But of no use , Please let me know if any thing missing form me or have any another solutions. Also please provide me any example if have.
Thank you,
Sandeep

hi.
but when using non-Oracle named parameter binding styles as you've done (ie. , :1), regardless of what number you give each bind variable, they are sequenced 0, 1, 2 etc. As such your bind variable :1 is the 0th parameter, and your bind variable is the 1st parameter.Your statment is correct.
:1 i used was actually on 0th position and :0 was on 1 position. Like you said in sequence 0,1,2 etc. Now i get the answer and i corrected My mistake by assigning right values to right binding variable. and problem just solve.
Thanks Chris.

How to create dynamic View Object and Dynamic Table

Dear ll
I want to create a dynamic view object and display the output in a dynamic table on the page.
I am using Jdeveloper 12c "Studio Edition Version 12.1.2.0.0"
This what I did:
1- I created a read only view object with this query "Select sysdate from dual"
2- I added this View object to the application module
3- I created a new method that change the query of this View object at runtime
    public void changeVoQuery(String dbViewName) {
        String sqlstm = "Select * From " + dbViewName;
        ViewObject dynamicVo = this.findViewObject("DynamicVo");
        if (dynamicVo != null) {
            dynamicVo.remove();
        dynamicVo = this.createViewObjectFromQueryStmt("DynamicVo", sqlstm);
        dynamicVo.executeQuery();
4- I run the application module for testing the method and I passed "Scott.Emp" as a parameter and the result was Success
5- Now I want to show the result of the view on the page, so I draged and dropped the method from the data control as a parameter form
6- I dragged and dropped the view Object "DynamicVo" as a table and I choose "generate Column Dynamically at runtime". This is the page source
