Need some guidance - SQL Query Bind Variables for VO Object

Hi,
I'm trying to customize a custom page and I'm new to this. Can you please guide me or send me an example on how to do this?
1) VO is having the query as "SELECT INVOICE_NUM, INVOICE_DATE, INVOICE_AMOUNT, ...... from AP_INVOICES_ALL" (no parameters in the where clause)
2) Added VO to AM
3) XML PG is designed with MainRN, QueryRN, and Instance of VO1 as Table region. Selected INVOICE_NUM, INVOICE_DATE as Searchable. QueryRN is ResultbasesSearch.
4) Deployed to E-Biz and users were able to query using INVOICE_NUM or INVOICE_DATE fields that are available in the QueryRN.
Now, they want to add FROM_INVOICE_DATE and TO_INVOICE_DATE to the Search Condition. So, I have added the condition in the VO Query as "SELECT INVOICE_NUM, INVOICE_DATE, INVOICE_AMOUNT, ...... from AP_INVOICES_ALL WHERE INVOICE_DATE between :0 and :1".
How to add these fields FROM_INVOICE_DATE and TO_INVOICE_DATE to the QueryRN? These are not part of VO.
How to bind them to :0 and :1? I don't see any controller here? Do I need set a new controller and write logic for getting result set?
Any sample script or link would really help.
Thanks in advance.
Ram

Hi Ram,
Hmmm, it is interesting.
Add two attributes to the page fromDate and toDate and in the controller class capture the values (like String fromDate = pageContext.getParameter("FromDate");) and invoke a method from AM and pass these parameters.
In the AM method call a method of VO and the VOImpl set and pass the bind parameters and execute the query again.
like
setWhereClause(" from_date = :1 AND to_date = :2");
setWhereClauseParams(null); // Always reset
setWhereClauseParam(0, fromDate);
setWhereClauseParam(1, toDate);
executeQuery();
Hope this will answer your question.
Krishna.

Extract the "bind" variables for a given query running in 10g.

how can we extract the "bind" variables for a given query running in 10g? The performance of a query may vary based on the parameters supplied to it. For example, a query like the following
SELECT * FROM CUSTOMER_ORDERS WHERE CUSTOMER = :CUST_ID
.might run differently when the :CUST_ID is "123" who may have very few orders versus "456" who may have tens of thousands of orders.
So, if we see a spike in the system due to a query, we need visibility into what the exact query syntax and values are for any database session. We're aware of an Oracle view called V$SQL_BIND_CAPTURE, but what we're finding with this view is that it's only a snapshot of variables that are refreshed on an interval. That view does not give us a live view into what values are being used in the various sessions in realtime.
If someone ould provide us with some SQL (or other means) to do get a realtime view into the SQL and variables currently running in the database, it would be greatly appreciated.

In addition to what's been said in the other thread, you could add a layer of logging either in the database or out.
v$sql_bind_capture and the associated ash view dba_hist_sqlbind contain sample data.
You could up the sample rate but it's not advisable - it's still just a sample.
If you're on 11g, this is where adaptive cursor sharing might help.
Not help in finding the values of your binds, but help in using different plans where there is such a skew for different bind values and the plan is perhaps wrong for customer 456.
The problem when you're got such a skew and you're using bind variables is that the two don't really go together.
When the query is next parsed and you've got bind variable peeking enabled, you might get the 123 plan is that is the bind value at parse time and then run into problems for 456 or even vice versa.
See http://jonathanlewis.wordpress.com/2009/05/06/philosophy-1/ for a discussion on binds and histograms which reflects the reasons for using either.

Need a SCCM SQL Query Report for Installed Software with Packages and Applications.

I need a report that will show the number of installs of all of the workstations applications and packages over a given period of time.
This will let us know how effective our deployments are and how well the on-demand software is being adopted.
Any help?

Your Install Source might be an option as most SCCM deployments will install from C:\Windows\ccmcache\xx [where xx is a random folder name]. Most software vendors will put an install source in the registry, but not all do, so it won't be completely accurate.
When software is installed manually, the install source path won't be C:\Windows\ccmcache\xx.
Here is a SQL query I have for Install Source:
SELECT v_GS_COMPUTER_SYSTEM.Name0 as 'Computer Name', v_GS_INSTALLED_SOFTWARE.ProductName0 as 'Software Title', v_GS_INSTALLED_SOFTWARE.InstallSource0 as 'Install Source', v_GS_INSTALLED_SOFTWARE.ProductVersion0 as 'Version', v_GS_INSTALLED_SOFTWARE.InstalledLocation0
as 'Installed Location', v_GS_INSTALLED_SOFTWARE.InstallDate0 as 'Install Date'
FROM v_GS_COMPUTER_SYSTEM INNER JOIN v_GS_INSTALLED_SOFTWARE ON v_GS_COMPUTER_SYSTEM.ResourceID = v_GS_INSTALLED_SOFTWARE.ResourceID
WHERE v_GS_INSTALLED_SOFTWARE.ProductName0 like '%Office 365 Pro%'
ORDER BY v_GS_COMPUTER_SYSTEM.Name0

if you have a lot of time you can follow some of the larger threads on AskTom. I think Mr. Kyte can do almost anything with SQL. And there are also some recurrent contributors as Stew Ashton provinding very interesting solutions.
Another option is to take a look at the answers in this forums: some participiants as Frank Kulash or Solomon Yakobson (to name just two of them) come up with astonishing pieces of SQL frequently.

Bind variable for view accessor

I am using a Gantt chart where I need to pass in a date field for the schedule as a bind variable.
Since this is a Gantt chart, there is no iterator binding for the child VO (the tasks) in my page definition.
    <gantt IterBinding="ParentVO1Iterator" id="ParentsVO1" xmlns="http://xmlns.oracle.com/adfm/dvt">
      <ganttDataMap>
        <nodeDefinition DefName="com.pat.model.view.ParentsVO" type="Resources">
          <AttrNames>
            <Item Value="ParentId" type="resourceId"/>
          </AttrNames>
          <Accessors>
            <Item Value="MainGantt" type="tasks"/>
          </Accessors>
        </nodeDefinition>
        <nodeDefinition type="Tasks" DefName="com.pat.model.view.MainGantt">
          <AttrNames>
            <Item Value="PatId" type="taskId"/>
            <Item Value="StartTimeDate" type="startTime"/>
            <Item Value="EndTimeDate" type="endTime"/>
            <Item Value="Patname" type="label"/>
          </AttrNames>
        </nodeDefinition>
I have tried retrieving the accessor through the parent VO, and setting the bind variable.
But I get an error if I fire executeQuery() on the child VO that says that the bind variable for the view link is missing.
        DCIteratorBinding iter = dcBindings.findIteratorBinding("ParentVO1Iterator"); // get parent iterator binding
        ViewObject vo = iter.getViewObject();
        MainGanttImpl childVO = (MainGanttImpl)vo.findAttributeDef("MainGantt").getAccessorVO(vo); //get the child VO through the accessor link
        childVO.setpViewDate(new Timestamp(((Date)getGanttDate().getValue()).getTime())); // get the date entered by the user and set to the child VO
        childVO.executeQuery(); //execute the child VO
Exposing the child VO impl through the Application module and setting the bind variable to that instance alone has no impact on the Gantt data returned.

We researched a bit more and hit upon the solution here.
Decompiling ADF Binaries: Search by child attributes on a tree table
I added the same bind variable to my parent VO (and added some SQL 'and : pViewDate = : pViewDate' to the query to just get it to work )
In the parent VO Impl class, I overrode the createViewLinkAccessorRS method:
   protected ViewRowSetImpl createViewLinkAccessorRS(AssociationDefImpl assocDef,
                                                      ViewObjectImpl accessorVO,
                                                      Row masterRow,
                                                      Object[] values) {
            ViewRowSetImpl v =
            super.createViewLinkAccessorRS(assocDef, accessorVO, masterRow,
                                           values);
      // Timestamp viewDate = (Timestamp )accessorVO.getNamedWhereClauseParam("pViewDate");
        v.setNamedWhereClauseParam("pViewDate", getpViewDate());
        return v;
public Timestamp getpViewDate() {
        return (Timestamp) getNamedWhereClauseParam("pViewDate");
This sets the child VO with the value of the bind variable that I have set to my parent VO. This got the Gantt working!

How to substitute a bind variable for a IN condition?

Dynamically I am setting the WHERE condition for one of my blocks using SET_BLOCK_PROPERTY Built in. The condition that I am attaching has two IN conditons..
For Eg.,
contracts_tbl.status_col IN ('NEW', 'OLD', 'EXPIRED', 'OPEN')
AND contracts_tbl.id_col IN (1, 2, 3, 4)
The number of choices in the IN condition will vary depending upon the user choice in my screen. Because of this the parsed SQL state is could not be shared and multiple of these are getting created in shared pool. To avoid this I would like to use bind variables.
There are two ways I am trying to do this..
1. Generating one bind variable for each value. i.e.,
contracts_tbl.status_cod IN (:global.var1, :global.var2,
:global.var3)
Now this could result it memory error if no. of choices exceeds the avilable memory. Also its a tedious task to purge the variables after querying the block. Also because of multiple IN conditions, the chances of different set of selections are possible and then again sharing will be minimal.
2. The second method is to set the one bind variable for each IN condition. i.e.,
:GLOBAL.Var1 := '( 'NEW', 'OLD', 'EXPIRED', 'OPEN' )';
:GLOBAL.Var2 := '(1, 2, 3)';
contracts_tbl.status_col IN :GLOBAL.Var1
AND contracts_tbl.id_col IN :GLOBAL.Var2
In this case, forms is not querying as the IN condition takes the global variable value as one string and the query returns no rows though there are plenty available for each status. Also any NUMBER type condtions erroring out as the , and ( are invalid numerals.
Q: Is there anyway you can make this work? or Is there any other better method to substitute bind variables in place to avoid creating new set of statements for each query in the shared pool?
Your suggestions and pointers are higly appreciated. Please respond immediately as this is a P1.
Thanks,
-- Raam.

2. The second method is to set the one bind variable for each >>IN condition. i.e.,
:GLOBAL.Var1 := '( 'NEW', 'OLD', 'EXPIRED', 'OPEN' )';
:GLOBAL.Var2 := '(1, 2, 3)';
contracts_tbl.status_col IN :GLOBAL.Var1
AND contracts_tbl.id_col IN :GLOBAL.Var2 This method should work - not sure if you put exact syntax in or not but your first assignment would cause a problem as everywhere you want one ' mark you would have to put two so that it does not close your quoted string
Try the following syntax:
:GLOBAL.Var1 := '( ''NEW'', ''OLD'', ''EXPIRED'', ''OPEN'' )';
:GLOBAL.Var2 := '(1, 2, 3)';
SET_BLOCK_PROPERTY('blk name',
default_where,
'contracts_tbl.status_col IN ' || :GLOBAL.Var1
|| ' AND contracts_tbl.id_col IN ' ||
:GLOBAL.Var2);
Hope this helps,

PL SQL using bind variables

I am very much new to PL/SQL to pardon my neivte.
I would like to have some PL/SQL code that uses
bind variables for insert statements and than issue
commit's after a specific number of inserts.
For example.
desc xxx.taba
a number
b varchar2(20)
I want to do someting like this:
declare
l_start number default dbms_utility.get_time;
create or replace procedure insert_xxx(commit in number)
begin
for i in 1 .. 1000
loop
:a:=i;
:b:=dbms_random.string('P', 20);
intert into xxx :a :b;
if i/mod=(number passed into to proc)
commit
end loop;
dbms_output.put_line
(round((dbms_utility.get_time-l_start)/100, 2) ||
' Seconds...' );
end;
end;
Can somebody help me out with the correct syntax
as I know it's incorrect.

A few remarks
- procedures don't have hidden variables defined in the outside world, as procedures are black boxes, which communicate only with the outside world
using the actual parameter list
- procedures don't commit. The caller should always commit!!!
- procedures don't commit every <n> records. A commit finalizes a logical unit of work, not a technical one.
If I would have been your supervisor and you would have presented this code, I would have fired you on the spot.
Committing inside a loop also increases the likelihood of ora-1555 errors.
So: remove the current parameter
a and b should be formal parameters of the procedure
Inside the procedure it should read
insert into xxx values (a, b)

Can we implement the custom sql query in CR for joining the two tables

Hi All,
Is there anyway to implement the custom sql query in CR for joining the two tables?
My requirement here is I need to write sql logics for joining the two tables...
Thanks,
Gana

In the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
Log on to your data source if necessary.
Under your data source, double-click the Add Command node.
In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
For example:
SELECT
    Customer.`Customer ID`,
    Customer.`Customer Name`,
    Customer.`Last Year's Sales`,
    Customer.`Region`,
    Customer.`Country`,
    Orders.`Order Amount`,
    Orders.`Customer ID`,
    Orders.`Order Date`
FROM
    Customer Customer INNER JOIN Orders Orders ON
        Customer.`Customer ID` = Orders.`Customer ID`
WHERE
    (Customer.`Country` = 'USA' OR
    Customer.`Country` = 'Canada') AND
    Customer.`Last Year's Sales` < 10000.
ORDER BY
    Customer.`Country` ASC,
    Customer.`Region` ASC
Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
For more information about creating parameters, see To create a parameter for a command object.
Click OK.
You are returned to the Report Designer. In the Field Explorer, under Database Fields, a Command table appears listing the database fields you specified.
Note:
To construct the virtual table from your Command, the command must be executed once. If the command has parameters, you will be prompted to enter values for each one.
By default, your command is called Command. You can change its alias by selecting it and pressing F2.

Functionality loss when 'Using Query Bind Variables in Advanced Search

Regarding: 'Using Query Bind Variables in Quick or Advanced Search'
The functionality to do the following is lost when I use bind variables in the Advanced Search:
"Result matches all conditions"
"Result matches any condition"
"Case Sensitive?"
Is there a way to Search with Detail groups but to keep the above functionality?

Hi,
Your application module impl java class extends the JHeadstart class JhsApplicationModuleImpl. THe latter declares a method:
public void advancedSearch(String viewObjectUsage,java.util.ArrayList arguments,Boolean allConditionsMet).
In your application module impl java override the advancedSearch method where you can include your own custom code before invoking the super method:
super.advancedSearch(viewObjectUsage,arguments,allConditionsMet);
The 'arguments' parameter is an arraylist of QueryCondition objects. You can set several properties for QueryCondition objects such as case-sensitity, operators etc.

Query Bind Variables problem

I have a ViewObject with bindvariable GroupnameItemname.
In JHeadstart AppDef this item is not bound to model, but included in Quick Search and Advanced Serach, as in "7.2.5. Using Query Bind Variables in Quick or Advanced Search"
First I get an error saying GroupnameItemname*Var* is not found on ViewObject, so I changed the bindvariables to GroupnameItemnameVar
Is something changed here? We are using JHeadstart 10.1.3.3.75 / JDeveloper 10.1.3.4.0
After changing the bindvariablename I have another problem:
I get an error in JhsApplicationModuleImpl.advancedSearch on these lines:
boolean isBindParam = !viewCriterium.isAttributeBased();
AttributeDef ad = isBindParam ? null : vo.findAttributeDef(attribute);
The first line returns false for my bindvariable, so the second line raises an error like "JBO-25058: Definition <attr> of type Attribute not found in <VO>".
In QueryCondition:
public boolean isAttributeBased()
return def!=null; //but def is not null here, it is an instance of DCVariableImpl
This used to work in previous versions of JHeadstart...
Please help,
Greetings HJH

In my MyApplicationModuleImpl (which extends JhsApplicationModuleImpl) I did override advancedSearch.
Copied the code from JhsApplicationModuleImpl and changed a few lines:
After
sLog.debug("executing advancedSearch for " + viewObjectUsage);
ViewObject vo = getViewObject(viewObjectUsage);
I added:
//clear bindParams:
String[] attrNames =
vo.getNamedWhereClauseParams().getAttributeNames();
for (int i = 0; i < attrNames.length; i++) {
vo.setNamedWhereClauseParam(attrNames\[i\], null);
sLog.debug("bindParam leeggemaakt: " + attrNames\[i\]);
And a bit later in the method I made a changed as follows:
// boolean isBindParam = !viewCriterium.isAttributeBased();
boolean isBindParam = viewCriterium.getName().endsWith("Var");
A bit crude, but worked for me...
Cheerio,
HJH

I am trying to write a query to aggregate paid_amount based on Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number and display description with Invoice_type 'I' when there are multiple records with the same Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number. When there are no multiple records I want to display the respective Description.
The query should return the following data set
Reference_No---Check_Number---Check_Date--------Description-------------------------------Invoice_Number----------Invoice_Type---Paid_Amount-----Vendor_Number

How to pass pageFlowScope variable value as bind variable for VO

Hi,
I have one fixed lov (not based on datasource), if i select any value in that lov i want to pass this value to a pageFlowScope variable.
After this i want to use this value as bind variable for VO. whenever the vo executes thereafter this bind variable should filter that vo results.
My jdev version: 11.1.0.0
Thanks in advance,
SAN

san-717,
can you elaborate on the use case instead of the implementation you don't get done? I understand you have data displayed in a tree: so lets assume the tree structure is Locations, Departments and Employees according to the Oracle HR sample schema.
1. What is the LOV supposed to do ?
2. Where is the LOV located ?
3. What values does the LOV show ?
4. Is the LOV a select choice component or a real LOV (with search dialog)
5. Where is the bind variable used ?
To me it sounds like you want to filter the tree data based on the select choice value. However, you wont do this by passing the bind parameter to all View Objects involved as they may not have the attribute in their query. So your use case is important to answer the question
