Bind Variables...Urgent

Thanks!
I build a SQL statement, PARSE and Execute...
Begin :l_result := Test(pa01=>':pa01',pa02=>':pa02'); End;
I am binding ':pa01', ':pa02'
When I try to Bind variables, it throws error "ORA-01036 illegal variable name/number".
Do I need to install any patch - current version Forms [32 Bit] Version 6.0.8.17.1 (Production)

Placeholders (:name) are bound by position in EXECUTE IMMEDIATE SQL statement. Hence Oracle does not consider multiple :p_comp_id in your statement to be the same thing. You would need to repeatedly bind them for each occurrence, or use an approach (DBMS_SQL.BIND_VARIABLE or EXECUTE IMMEDIATE PL/SQL block) which binds by name or position / name.
In the case of the above example you would have a USING clause similar to the below (Note that I am unable to test this).
EXECUTE IMMEDIATE sql_statement
   USING p_comp_id, p_comp_id, p_site_id,
      p_site_id, p_task_type, p_comp_id,
      p_po_no, p_ebiz_sku_no, p_sku_status,
      p_lp, p_batch_no, p_comp_id;

could anyone tell what could be the wrong. Do we need to set bind variable in view link Explicitly? or any other alternative.
Its very Urgent.

Hi,
I have faced similar problem some time ago. I could not find any solution except removing bind parameters in where clause. I tried to change binding style but it also didn't work. I think the problem is caused by view link's where clause.

How to assign sessionscope variable to the bind variable in Query of VO

Hi all,
I want to know how to assign a sessionscope variable in the binvariable of Query in VO
My sessionscope variable holds the value of currently selected column in the table. eg:empname of the currently selected column which is in empdetails table...
I want display the schemes available for the selected employee in the next table..The schemes are in another table named empschemes which has the empname and empschemes as column
I have created a vo for empschemes table with bind variable 'scheme_bind'..I need to set the sessionscope variable '#{sessionScope.empname}" to the bind variable.
Its urgent,..Pls do reply asap
Thanks in advance
Nasrin

HI,
You can use
adf.context.sessionScope.get("YourSessionVariable")this code for assigning VO's bind variable value.write this code where you create bind variable and do not forget click on expression radio button.

HELP: Bind Variable does't work in SQL statement

I am trying to connect a text item bind variable into the where
clause of an SQL statement. Specifically into an INSERT
statement and SELECT statement. It gives me an message box
error, saying it is unable to insert. There is no Oracle error
number associated with it. Is this a bug? Has this happened to
anyone else. PLEASE HELP! URGENT!

I assume this is a forms problem. You need to check out the
dbms_error_code and dbms_error_text to get your oracle error.
You can trap and report these types of errors using an on-error
trigger. Also, if you are using the default menu then check
out help -> display error immediately after the form reports
unable to insert ...... This should give you enough information
to solve your problem, or at least point you in the right
direction.

Need help in Bind variable in AF Query LOV

Hi,
i have one problem with bind variable, if i use bind variable in the LOV VO Query then my result is not coming, if there is not bind variable it's working fine and if i use the bind variable in the LOV search option then it's working fine but if i hide the bind variable and set the value in AM prepareSesstion method the LOV is not returning any value. I try to return the values also all values are also coming but those values are not setting to AF Query Attribute.
Query is:
select substr(d.description,0,40) description
from cm_system_users a,
cm_user_responsibilities b,
cm_responsibility_processes c,
cm_processes d
where a.nt_login =:B_NT_LOGIN
and a.user_id = b.user_id
and trunc(sysdate) between b.eff_date and nvl(b.exp_date,sysdate + 1)
and b.RESPONSIBILITY_ID = c.RESPONSIBILITY_ID
and c.process_type = d.process_type
and d.enabled_flag = 'Y' order by d.arguments_flag
AM Method:
CmProcessViewImpl vo = getCmProcessView();
String nt_login = getUserPrincipalName();
vo.setNamedWhereClauseParam("B_NT_LOGIN", nt_login.toUpperCase());
vo.executeQuery();
Can any one help me in this. it's urgent for me.

This is a little underdescribed. IIUC, the view object in question is being used as a target for a view accessor, correct? (Otherwise you'll have to be more explicit about what you mean by "Query LOV".
If I'm right, there are two possibilities:
1) You are using a VO instance in a shared application module instance. If so, make sure your code is in the prepareSession() for that application module class if it's session dependent (as it seems to be below), you need to make sure the application module instance is shared at session scope.
2) You've based the view accessor directly on the VO definition. This basically creates an anonymous VO instance; I don't think there's any way to use prepareSession() to set a bind variable on such an instance (which won't be created until the accessor is first used). You might be able to get by with putting similar code into the view object class' create() method, but I haven't tested this.
If your code is in your primary application module class (as opposed to the class for a shared AM instance), the problem here is that getCmProcessView() returns the VO instance from that application module instance's design-time data model, which is never used by view accessors.
By the way, why do you need to do this in prepareSession() instead of at the view accessor level? I believe you can get the logged in user name (for the view accessor) in with the groovy expression
viewObject.DBTransaction.session.userPrincipalName
or possibly just
DBTransaction.session.userPrincipalName
(despite this involving DBTransaction, it returns the web app user name, not the DB username).
That's a 100% declarative solution, if you don't count the Groovy expression as non-declarative.
If you're afraid of a user executing the LOV (somehow) before the bind variable value gets set, just ensure that the bind variable is marked "required".

Report Performance with Bind Variable

Getting some very odd behaviour with a report in APEX v 3.2.1.00.10
I have a complex query that takes 5 seconds to return via TOAD, but takes from 5 to 10 minutes in an APEX report.
I've narrowed it down to one particular bind. If I hard code the date in it returns in 6 seconds, but if I let the date be passed in from a parameter it takes 5+ minutes again.
Relevant part of the query (an inline view) is:
,(select rglr_lect lect
,sum(tpm) mtr_tpm
,sum(enrols) mtr_enrols
from ops_dash_meetings_report
where meet_ev_date between to_date(:P35_END_DATE,'DD/MM/YYYY') - 363 and to_date(:P35_END_DATE,'DD/MM/YYYY')
group by rglr_lect) RPV
I've tried replacing the "to_date(:P35_END_DATE,'DD/MM/YYYY') - 363" with another item which is populated with the date required (and verified by checking session state). If I replace the :P35_END_DATE with an actual date the performance is fine again.
The weird thing is that a trace file shows me exactly the same Explain Plan as the TOAD Explain where it runs in 5 seconds.
Another odd thing is that another page in my application has the same inline view and doesn't hit the performance problem.
The trace file did show some control characters (circumflex M) after each line of this report's query where these weren't anywhere else on the trace queries. I wondered if there was some sort of corruption in the source?
No problems due to pagination as the result set is only 31 records and all being displayed.
Really stumped here. Any advice or pointers would be most welcome.
Jon.

Don't worry about the Time column, the cost and cardinality are more important to see whther the CBO is making different decisions for whatever reason.
Remember that the explain plan shows the expected execution plan and a trace shows the actual execution plan. So what you want to do is compare the query with bind variables from an APEX page trace to a trace from TOAD (or sqlplus or whatever). You can do this outside APEX like this...
ALTER SESSION SET EVENTS '10046 trace name context forever, level 1';Enter and run your SQL statement...;
ALTER SESSION SET sql_trace=FALSE;This will create a a trace file in the directory returned by...
SELECT value FROM v$parameter WHERE name = 'user_dump_dest' Which you can use tkprof to format.
I am assuming that your not going over DB links or anything else slightly unusual?

How to Dene a Data Link Between Queries: Bind Variables

This is an interesting topic and I cannot get it to work using Bind Variables.
I have 2 queries: Q1 and Q2. Q2 needs c_id, account_code and account_type from Q1.
Whe I run the data template below, I get only the data for Q1.

Can I use bind variable instaed of writing static COLUMN Name

Hi , I am having a table containing id and column names, the data is stored against that id in other tables. Now I wish to update data into another table so that it goes into apppropriate column without using decode function.
I am trying to do this:
EXECUTE IMMEDIATE 'update TEST set :1 = :2
where PROJECT_ID= :3 and UNIQUE_ID= :4' using P_DEST_COLUMN, P_TEXT_VALUE, P_PROJ_ID, P_TASK_UID;
the values P_DEST_COLUMN, P_TEXT_VALUE, P_PROJ_ID, P_TASK_UID are populated using a cursor in PL/SQl
Is this statement valid? If not can you tell me how to do it as I am getting some error I am unable to comprehend.
thanks
Rishabh

Column names cannot be substituted at run-time as bind variables. If you need to specify the column name at run-time, you'd need to construct a new string and execute that string dynamically, i.e.
EXECUTE IMMEDIATE 'UPDATE test SET ' || p_dest_column || ' = :1 ' || ...From a data model standpoint, storing column names as data elements in another table is generally a rather poor idea. It's likely to make ad-hoc reporting nearly impossible and to cause a lot more parsing than would otherwise be required.

Dynamic sql and bind variables

Hi,
I have a stored procedure which filters a table on 5 five columns. The filters come from the input parameters,
and these 5 parameters can come in any combination, I mean some of them may be null and some of them may not be null.
So I constructed the where filter of the query with IF blocks like the following:
dynamic_query := 'select * from TESTTABLE where 1= 1';
IF (P1 is not null) THEN
dynamic_query := dynamic_query || ' AND column1 = :1';
END IF;
IF (P2 is not null) THEN
dynamic_query := dynamic_query || ' AND column2 = :2';
END IF;
IF (P3 is not null) THEN
dynamic_query := dynamic_query || ' AND column3 = :3';
END IF;
IF (P4 is not null) THEN
dynamic_query := dynamic_query || ' AND column4 = :4';
END IF;
IF (P5 is not null) THEN
dynamic_query := dynamic_query || ' AND column5 = :5';
END IF;
OPEN CUR_OUT FOR dynamic_query USING P1, P2, P3, P4, P5;
The problem is how can I construct the USING and bind parameters, I cannot use "USING P1, P2, P3, P4, P5" because some of bind variables
may not be in dynamic query if the input parameters are null. Is there a way to overcome this problem without writing all the 2 ^ 5 combinations?
Any help is greatly appreciated.

here it is in the Tomer Cohen way:
IF (P1 is not null) THEN
dynamic_query := dynamic_query || ' AND column1 = :1';
ELSE
dynamic_query := dynamic_query || ' AND :1 IS NULL';
END IF;
IF (P2 is not null) THEN
dynamic_query := dynamic_query || ' AND column2 = :2';
ELSE
dynamic_query := dynamic_query || ' AND :2 IS NULL';
END IF;
IF (P3 is not null) THEN
dynamic_query := dynamic_query || ' AND column3 = :3';
ELSE
dynamic_query := dynamic_query || ' AND :3 IS NULL';
END IF;
IF (P4 is not null) THEN
dynamic_query := dynamic_query || ' AND column4 = :4';
ELSE
dynamic_query := dynamic_query || ' AND :4 IS NULL';
END IF;
IF (P5 is not null) THEN
dynamic_query := dynamic_query || ' AND column5 = :5';
ELSE
dynamic_query := dynamic_query || ' AND -1 = :5';
END IF;
OPEN CUR_OUT FOR dynamic_query USING P1, P2, P3, P4, P5;Amiel Davis

It just keeps on executing for sometime and then disconnects itself from database What was the indication that told you that it disconnected? Was there a visible indication of this disconnect?
Did you get ORA-03113?
===========================================
ORA-03113: end-of-file on communication channel
Cause: The connection between Client and Server process was broken.
Action: There was a communication error that requires further investigation. First, check for network problems and review the SQL*Net setup. Also, look in the alert.log file for any errors. Finally, test to see whether the server process is dead and whether a trace file was generated at failure time.

How to update bind variable and restrict values in a Model Driven LOV?

Hi Guys,
Using JDev 11.1.1.2.0
I've recreated an excellent Frank Nimphius article about restricting values derived from a model driven LOV (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/44-restrict-lov-169186.pdf)
But my bind variable isn't updating. Deleting the bind variable gets me the entire LOV. Activate the code below and insert a bind variable into the where clause like Frank says and I get nothing back. Bind variable is blank. Any ideas? Code wasn't supplied with the article. It seems simple enough but the bind variable isn't updating in the SQL, even though the updated value shows up here...
public void onLovLaunch(LaunchPopupEvent launchPopupEvent)
    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    FacesCtrlLOVBinding lov = (FacesCtrlLOVBinding)bindings.get("DepartmentId");
    lov.getListIterBinding().getViewObject().setNamedWhereClauseParam("deptId","60");
    System.out.println("lov name: " + lov.getName().toString());
    System.out.println("lov Param Attrs: " + lov.getListIterBinding().getViewObject().getNamedWhereClauseParams().getAttribute("deptId").toString());
    System.out.println("lov View Object: " + lov.getListIterBinding().getViewObject().getName().toString());
    System.out.println("lov IterBinding: " + lov.getListIterBinding().getName().toString());
   }Gets me ...
lov name: DepartmentId
lov Param Attrs: 60
lov View Object: _LOCAL_VIEW_USAGE_lov_model_queries_EmployeesView_DepartmentsView
lov IterBinding: DepartmentIdList_2

That's a good idea, but it's still not working. Here is how I implemented it. It might be different from your suggestion as I'm still pretty new to this.
I have a recursive tree table. You select a node. You then click a button which calls the listener below. "findParents" is a method call to the AppModuleImpl class and it finds all parent nodes of your selection. "restrictPartBomLOV", also of the AppModuleImpl class, then modifies the model driven lists' View Object (partBomLOV) to exclude those parent node values.
The resulting model driven LOV on the popup should be updated, yeah? But it still isn't udpating. If I manually type in the updated Where clause in PartBomLOV.xml query tab, it works, but it doesn't programmatically.
public void insertPopupFetchListener(PopupFetchEvent popupFetchEvent)
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding("findParents");
    parents = (List)operationBinding.execute();
    operationBinding = bindings.getOperationBinding("restrictPartBomLOV");
    operationBinding.execute();
   public void restrictPartBomLOV(List parents)
      ViewObjectImpl vo = getPartBomLOV();
      String wcl = "";
      Object[]   p = parents.toArray();
      for(int i = 0; i < p.length; i++)
         if (i == 0)
            wcl = wcl + "PNUM <> '" + p.toString() + "'";
else
wcl = wcl + "AND PNUM <> '" + p[i].toString() + "'";
vo.setWhereClause(wcl);
System.out.println(vo.getWhereClause().toString());
vo.executeQuery();

          v_Select_Statement := v_Select_Statement || ' intersect ' ||
                                'SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Element_Attribute_Id = ' || Element_Attr_Id_Table_In(i);
        END IF;
      END LOOP;
      EXECUTE IMMEDIATE v_Select_Statement INTO v_Element_id;
      RETURN v_Element_Id;
    END;What this does is to create a query similar to this:
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 1 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 2 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 3 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 4 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 5;
I am using Dynamic SQL because the number of intersect pieces can vary from 1 to 15 and in the future it can grow.
The problem that I have is that because the literals are part of the string, the query is being hard parsed every single time. In our production environment this means 100s of thousands of times per day which according to our DBA has added 15% plus to our average load. I know that I can come up with a rewrite to avoid this, but I was wondering if there is a parameter I can set at the session or at the database level where the database itself can convert this kind of query into one with bind variables.
Thanks,
Tom

Basically I have an XML document.
The document has ELEMENTS.
ELEMENTS can have attributes.
There is a many to many relationship between ELEMENT and ATTRIBUTES so I have a XREF table to represent this relationship.
When I receive a new document, I need to determine if a group of ATTRIBUTES already exist together in the XREF table so I have to find their common ELEMENT_ID or NULL in which case I would create a new ELEMENT and associate the new set of attributes to the new ELEMENT.
Since the number of attributes can vary from 1 to around 15 for now, I had to dynamically build the query that find the common ID(intersect) if it exists.
Here is some DDL and inserts:
CREATE TABLE ELEMENT(ELEMENT_ID NUMBER NOT NULL);
CREATE TABLE ELEMENT_ELEMENT_ATTRIBUTE_XREF(Element_Id NUMBER NOT NULL, Element_Attribute_Id NUMBER NOT NULL);
ALTER TABLE ELEMENT_ELEMENT_ATTRIBUTE_XREF ADD CONSTRAINT ELEMENT_ATTR_MANY_2_MANY_PK PRIMARY KEY(Element_Id, Element_Attribute_Id);
ALTER TABLE ELEMENT ADD CONSTRAINT ELEMENT_PK PRIMARY KEY(Element_Id);
INSERT INTO ELEMENT VALUES(1);
INSERT INTO ELEMENT VALUES(2);
INSERT INTO ELEMENT VALUES(3);
INSERT INTO ELEMENT VALUES(4);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(1, 1);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(1, 2);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(2, 1);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 1);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 3);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 4);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 5);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(4, 6);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(4, 7);
So for instance if I passed an array (Attribute ID Tab) containing ELEMENT_ATTRIBUTE_ID list 6 and 7 I would get 4 as the answer.
Hope this helps,
Thanks,
TomAwesome, thanks!
I'm not sure this works 100% for what you need, but I thought I'd give it a shot. I've used a built in array (sys.odcinumberlist) that you should have access to on your installation (assuming you have a relatively recent version of Oracle).
I left out the part where you would loop through the array you are currently passing in to your procedure to build up this new array that you can use in a SQL statement.
Cheers,
create or replace procedure maybe_this
   in_list           sys.odcinumberlist
is
   l_commonality     number;

      from
            table(cast(in_list as sys.odcinumberlist)) list
        , element_element_attribute_xref   xref
      where
         xref.element_attribute_id = list.column_value;
      dbms_output.put_line('match on element_id = ' || l_commonality);
   exception

         dbms_output.put_line('no match');
   end;
end;

Null check for a bind variable in view criteria

Hi, Greetings.
I am using Jdeveloper 11.1.2.0.
I have a view object, LocationsView, for locations table of the XE database.
I want to apply a condition, ((:bind_var is null) or (:bind_var is not null and location_id = :bind_var), in this LocationsView.
That is, I want to apply the condition only if the bind variable value is not null.
How can I construct this condition using a declarative view criteria?
Any help and hints on this regard is greatly appreciated.
Regards,
Guru K

Hi,
Thanks for the update and it is working perfectly fine.
Now, how can I set the "ignore null values" option as checked if I am constructing the criteria programmatically using view criteria row and view criteria item at runtime.
Thanks and regards,
Guru K
