bind variables using the values in the collection
Hi the gems... Good afternoon...Can we not use plsql values in the collection in the USING clause to pass the bind variable values...
I wrote the procedure to kill all sessions that cross the parameter OPEN_CURSORS below. the query, I found only three sessions that exceed. But when I execute my procedure so those are not removed, execution gives me an error also. He simply executed but no session has been killed.
My part of the code is as below:
..........
..........
..........
OPEN rc FOR v_sql;
FETCH rc BULK COLLECT
INTO v_tt_sessions;
LOOP
EXIT WHEN v_tt_sessions.COUNT = 0;
FOR idx IN 1 .. v_tt_sessions.COUNT
LOOP
EXECUTE IMMEDIATE 'alter system kill session '':a,:b'' immediate'
USING v_tt_sessions(idx).sid, v_tt_sessions(idx).serial#;
END LOOP;
END LOOP;
CLOSE rc;
.........
...................
..........
..........
OPEN rc FOR v_sql;
FETCH rc BULK COLLECT
INTO v_tt_sessions;
LOOP
EXIT WHEN v_tt_sessions.COUNT = 0;
FOR idx IN 1 .. v_tt_sessions.COUNT
LOOP
EXECUTE IMMEDIATE 'alter system kill session '''||v_tt_sessions(idx).sid||','||v_tt_sessions(idx).serial#||''' immediate';
END LOOP;
END LOOP;
CLOSE rc;
..........
..........But the doubt is when I removed the variable of liaison with the values of the collection hard-coded (in my first post), then this process works very well. But I want to use bind variables.
You cannot use bind variables in this situation. You can use bind variables for the DML statements.
I'm surprised that you have no error, but I guess that this block of code explains everything:
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(SQLCODE || ' : ' || SQLERRM);
You concatenate values to build a single command ALTER SYSTEM and run, just like your second attempt.
You don't need to have a dynamic cursor either.
for r in (
select v.SID, u.serial#, count(v.sid)
from v$open_cursor v, v$session u
where v.CURSOR_TYPE='OPEN'
and v.sid=u.sid group by v.sid, u.serial#
having count(v.sid)>190
order by count(*) desc
)
loop
execute immediate 'alter system kill session '''||r.sid||','||r.serial#||''' immediate';
end loop;
And of course, I agree with the comments of Keith (assuming that this is not just an exercise).

How to swap two values without using the third variable using the procedure
How to exchange the two values without using the third variable using the procedure?
In a procedure using two mode we pass two values A = x and B = y, and let us pass parameters to receive the output has A = y and B = x without using the third variable
Published by: Millar on August 19, 2012 11:23Your question doesn't seem wise. As written, there is no reason to a third variable, just
CREATE OR REPLACE PROCEDURE( x IN number, y IN number, a OUT number, b OUT number ) AS BEGIN a := y; b := x; END;If it's an interview question, I suspect that the intention was that you had two settings IN OUT and you wanted to swap the values without the help of a third variable.

problem with bind variables in the SQL query view object
Hi all
I use JDev 11.1.2.4.0.
I have a problem with bind variables in the SQL query view object.
This is my original SQL
SELECT sum(t.TIME) , t.legertype_id FROM LEDGER t WHERE t.nctuser_id = '20022' AND to_char(t.insertdate,'YYYYMMDD') in ('20130930','20130929') group by t.legertype_idIn my view .xml object query tab, I am writing this
SELECT sum(t.TIME) , t.legertype_id FROM LEDGER t WHERE t.nctuser_id = '20022' AND to_char(t.insertdate,'YYYYMMDD') in :dddd group by t.legertype_id
Davis here is a variable of Type liaison: String, updatable and necessary.
I try to deal with Davis as ('20130930 ', ' 20130929') hoping the view object, run as my original SQL.
But failed. The view object retrieves 0 line after that I run.
Why?
Thank you! ('2original SQL0130930', '20130929') ('20130930 ', ' 20130929')
A variable binding cannot be used as this is why you must use years table. Check decompilation binary ADF: using oracle.jbo.domain.Array with ViewCriteria to see a solution.

How can insert quary in database by using the collection.
Hi friends,
My friend advice me to insert several point with collection for the use of multiple lines. But I don't know how to use the collection. How do I create the form to insert data using the collection.
Please send me any link or example .au insert data into database by using the collection.
My problem is:-
I have a bill with several point for example. Grapes (25) with amount here and now I want to add these question with quantity in my database, Badam (145), banana (49), Apple (12)
When I finally click on submit button.
Actully I was used as a table but I am facing a problem when using tabular, tabular, I enter first item for example. Apple and there quantity for example. 12 in the textfield and after clicking on Add line enter Buttom went to the database. but I want that entry should not go the database. But only the new line should add when I click on the button Add a line.
I want all these point 4 should enter into the database when I click on Submit Final.

I would do something like the code:
BEGIN DECLARE vDATE DATE; BEGIN vDATE := TO_DATE(:P1_DATE1,'DD.MM.YYYY'); WHILE vDATE <= TO_DATE(:P1_DATE2,'DD.MM.YYYY') LOOP INSERT INTO ABC (DTE, LEAVE) VALUES (vDATE, :P1_C); vDATE := vDATE + 1; END LOOP; END; END;You must ensure that the datepicker points both use the ' JJ. MM YYYY ' date format.

The use of bind variables in the application process
Bind variables refer to elements of session state supported in queries in an application request process?
All the examples I see show how to pass client side values using the $v () function and the htmldb_get object addParam method and refer to them using the wwv_flow.g_xNN variables, but already available in session state values, I should be able to use them directly in the process, right?
Thank youYes, they are supported.

pass the binding variable to the af:table using the menu drop-down
I need to create an af:table to pull all employees belonging to a Department. I created the table based on a viewobject.
The query in the view object has a variabe bind, for example:
Select * from employee where deptname to (select deptname of Department where deptid =: deptid)
My question is how to get the deptid selected in a drop-down list value passed to the query of the table of the adf?
The user, what version jdev you use?
Where is the location THAT LOV located on the page? Once you have the service ID, you can use the executeWithParams to run the query and display the result in the table.
If this isn't what you want to elaborate on the use case.

Procedure of the ODI - Bind Variables in the conditional statements
In an ODI procedure, is it possible to add a conditional statement around bind variable? For example, if I use OdiOutFile as the command on the target and Oracle as the command on the Source, I can use bind variables to fill the data in this table (we are in fact using OdiInvokeWebService and passing a XML structure very complex, but it's easier for testing):
OdiOutFile-FILE = C: / TEST. TXT
< person >
< first > #FIRSTNAME < / first >
< Middle > #MIDDLENAME < / Middle >
< last > #LASTNAME < / last >
< / person >
It is a way to add a conditional statement using one of these bind variables? For example, if I wanted to test #MIDDLENAME null and null value, produced this portion of XML, such as:
OdiOutFile-FILE = C: / TEST. TXT
< person >
< first > #FIRSTNAME < / first >
< % if (#MIDDLENAME! = null) {% >}
< Middle > #MIDDLENAME < / Middle >
< %} % >
< last > #LASTNAME < / last >
< / person >
This type of scriptlet syntax seems to work fine, as long as the binding variable is not in the mix (if I put "true is true" or "true == false" in the case, it shows or does not show this line in the XML file, as expected). I use ODI 11.1.1.7.0
----------------------
Post edited by: KevinPratt
Thanks for the reply! As suggested, in what follows, I changed the command and it works as you want
OdiOutFile-FILE = C: / TEST. TXT-APPEND
< person >
< first > #FIRSTNAME < / first >
< @ if (!) (("#MIDDLENAME".equals(""))) {@ >}
< Middle > #MIDDLENAME < / Middle >
{< @} @ >
< last > #LASTNAME < / last >
< / person >
Using the syntax <@ ...="" @="">serve your purpose. Also, I think you might want to include the variable binding in the quotation to avoid syntax errors.

Please help me to better understand and to right the next point
to move from a PPT available in internet, I read a sentence under the heading "Why use collections?" Please find here
Use of complex data sets information to host non-PL/SQL environments using table functions
I think I understand: it means that complex data sets can be collected from oracle using only a single sql statement by using the installation, called Oracle Pipelined Table functions. http://www.akadia.com/services/ora_pipe_functions.html]
Is any other installation in oracle to the serveup of complex datasets of the information to the host non-PL/SQL environments?
Published by: o Manjusha Muraleedas, error corrected spelling.I watched the presentation and here's how I read it (although you might be better to ask the author):
Manjusha Muraleedas wrote:
My question is, why the statement "Serve up complex data sets of information to host non-PL/SQL environments using table functions" came under the title "Why use collections?". Just because there's an installation? or any other really good news?There is a hypothesis that is unwritten in the presentation: "complex" data is data that must be handled in PL/SQL, because only SQL does not work.
Nowhere the author says that a pure SQL solution should be changed into a solution of PL/SQL.
Once you decide that you must use the PL/SQL, you might want to put your data in collections in scalar variables.
I understand, complex data, works of art (suppose a structure with 3 columns of tables joing 5) can be meet non-pl/sql envirormment like Java, the use of the ref Cursor or xml. Collection using to do the same thing, this is not a good option.
Again, I think that the author uses "complex" as a shortcut for 'need to PL/SQL in the first place'. If the data must be processed in PL/SQL, there is no need to use PL/SQL scalar variables or collections.
I would say "use of the ref Cursor. Providing relational data in format XML should be the exception, not the rule. It has a cost of additional performance.Now lets talk about pipeline table functions.
...
functions table pipeline reached the performance of parallel processing. so even if binding commodity of time and memory is there, it will be performs better than refcursors or xml?Pipeline table functions perform no better than the ref Cursor. There are two processes running, one to SELECT and the other for the function, there will be more work on the server. With a ref cursor, there is a fair process to return the data.
Parallel processing is not a problem. If you can make it work in plain SQL, you can do in parallel in SQL simple.

Bind variables in the SQL causes slow
We have a strange problem in our PeopleSoft system that I traced to a SELECT statement using bind variables, if hardcode us them values in SQL, it runs very fast.
but using bindings (what the application does) a problem of efficiency. I'm going to re - write the code that is based on a view of three tables joined to go against
the base tables and I don't think I'll have a problem. However, I would like to know why the problem exists in the first place. Here is what info I have:

Update Bind variable during the click on chart?
New to ADF, so getting started is a little rough right now.
I created a couple of display objects, trained in my JSF page and created the graphics bar out of them. I can click on the series in the bar chart and update a table ADF without problem. What I would do, is to take the result of the click (I know how to find the value of the Group since the click) and past this value in another view to display a new table.
So the question is how can I update a binding for a display object variable and display the results in a table of the ADF?
I have a query: "select user_name, user_role from users where user_id =: userId" with a variable named liaison: userId. It took the form of the ADF on my page and rendering: false and display: false. What I would do, is updated ": userId" variable with a value of the graph and display of the form.
Any help?
Thank you!Hello

Bind Variables on the view objects child definition
JDeveloper 12 c
I have an interesting question. I have a view (AisWebModulePrivsVO) object that uses a bindvariable hardcoded in the view object.
SELECT * FROM SYS. DBA_ROLE_PRIVS where DEALER =: bvUserName
If I put this in the request module I can programmatically set the variable binding (view object contains the getter/setter for the binding variable).
AisWebModulePrivsVOImpl voTest = am.getAisWebModulePrivsVI ();
voTest.setbvUserName ("ARAWLS");
voTest.executeQuery ();
System.out.println ("test reports:" + voTest.getRowCount ());
and get the correct number of records based on return on the user and database roles. If it works.
What does NOT work, it is when this display object is a recording of 'the child' to another display object (as specified by a link between the two and by setting the object from a point of view as one child of the other in the module of the application).
AppModule looks like this:
CgRefCodesVO
AisWebModulePrivsVO
In this case, I have a view called cgRefCodeVO parent object. There is a link between this and the AisWebModulePrivsVO. The relationship works.
AISMenuAppModuleImpl m = ADFUtils.getApplicationModuleForDataControl (appMod) (AISMenuAppModuleImpl);
CgRefCodesVOImpl cgRefVO = am.getCgRefCodes1 ();
AisWebModulePrivsVOImpl modsVO = am.getAisWebModulePrivs1 ();
modsVO.setbvDBUserName ("ARAWLS"); This doesn't seem to work here...
cgRefVO.executeQuery ();
All lines rs = cgRefVO.getRowSet ();
RS. Reset();
While (rs.hasNext ()) {}
CgRefCodesVORowImpl CgRefRow = rs.next ((CgRefCodesVORowImpl));
System.out.println ("RvLowValue:" + CgRefRow.getAttribute ("RvLowValue"));
RowIterator aisModulesRowIter = CgRefRow.getAisWebModulePrivs ();
System.out.println ("number of children:" + aisModulesRowIter.getRowCount ());
}
The code compiles and runs. She translates: "County of the child: 0" for each row returned by the
I also tried:
VM VariableValueManager = modsVO.ensureVariableManager ();
vm.setVariableValue ("bvDBUserName", "ARAWLS");
And:
modsVO.setNamedWhereClauseParam ("bvDBUserName", "ARAWLS");
and (of ( )
@Override
protected void executeQueryForCollection (Object, object, Object [] object2, int i) {}
I coded everything hard to see if it would work.
setNamedWhereClauseParam ("bvDBUserName", "ARAWLS");
super.executeQueryForCollection (object, object2, i);
}
and from there, I changed around the order to execute the objects in view.
How can I set the variable binding in the object view child?
Thank you
Stuart
It is an interesting example how ADF works up to a certain point... then you need to start to make cuts to modify its behavior as you wish.
I decided that it was just easier to delete 'the child' parent (in the app module) and create a view of criteria on this subject for what would basically query the records to get the same results, like a child.
Perhaps not as elegant, but so much easier.
Thanks for your help.

When I go from ODP.NET to the ODP.NET managed some of my questions begins to throw errors missing bind variable.
I reproduced with a simple example that uses a variable called liaison: unitName
It's the example SQL:
SELECT
: unitName
Of
DOUBLE
Now, if I add a comment at the beginning of the SQL like this:
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
It works, but if I have a variable binding in a comment that is located on a number of the 'same' line, I get ORA-01006:
This causes the error:
-First line comment
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
Kind regards
-Tommy
I was able to reproduce this problem. I filed Bug 19433348 on your behalf.
The circumstances in which the bug occurs are fairly easy to get around.
(1) remove the colon in the second commented line.
(2) add a space between the '\n' and ' - '.
If you are one of those things, you won't encounter the bug behavior.

I changed and then brought back to the State that you had.
The problem here is that you have status and Seq_id returned with APEX_ITEM. HIDDEN, but you have not selected the Show check box for those columns attribute report tab.
Thus there is no f06 and f09 only named elements in your HTML DOM and therefore no APEX_APPLICATION. G_F06 and G_F09. If your processes
FOR correct here is what you do
1. mark the status and Seq_id as indicated in the report attribute tab columns
2. change the ACE status display hidden to report column Standard. Change display of the Seq_id also report Standard columnNote that when a column is not marked to show in the report he becomes any and you don't see the associated items in the DOM HTML.
See you soon,.

JDev 11.1.2.1 method Execute (with bind variable) before the page is displayed
Hi all
I have a view object with a query that uses a variable binding. I drag the data on my .jsf page control to create a table. I create a query method on a bean in sight. The query method uses the content of one of the attributes of the bean to set the link for the query variable:
vo.setNamedWhereClauseParam ("CraIdBindVar", sessionBean.getCraId ());
I put a button on the page that calls the method of the request and it fills the table. That's fine, but I don't want the user to have to click the "query" button when browsing this page. I found forums dealing with create an AMImpl.jave method, create a link on the page, create an executable file for the link. It works that the method is executed until the page appears. However, the AMImpl method cannot call sessionBean.getCraid () to obtain the data required to complete the binding variable.
Is it possible to run my method of view range bean before the page is displayed? Or maybe a way for the AMImpl.java method to access the range of view variable?
Thank you, SteveSteve,
You can drag a call method on the workflow activity. Select the new method call activity, and open the property inspector. Here you choose your bean method in the method property. Now, first of all, you go to this activity of method call, then the page.Timo
