• 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_id
  

  In 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.

• Get the bind variables name string SQL or the cursor

  Hello
  
  Is there way to get of the bind variables name string SQL or the cursor?
  
  Example of

  DECLARE
    l_sql VARCHAR2(2000);
    desctab DBMS_SQL.DESC_TAB;
    curid   PLS_INTEGER;
  BEGIN
  
    l_sql := 'SELECT * FROM emp WHERE mgr = :X and deptno = :Y';
  
    curid := dbms_sql.open_cursor;
    dbms_sql.parse(curid, l_sql, dbms_sql.NATIVE);
    ....
  END;

  What I mean with the SQL string:
  I love to get using some functions from above code variable l_sql all the bind variable.
  In this case the function should return array where is for example: X and: Y
  
  Back to bind the cursor variable names, I mean same but rather string I pass number of cursor.
  
  Y at - it sucks ready function or some may share a code customized for this purpose?
  
  Thanks
  
  Kind regards

  I found there are wwv_flow_utilities.get_binds of the function not documented in APEX packages that do what I want.
  Usage example

  set serveroutput on
  DECLARE
    binds DBMS_SQL.varchar2_table;
  BEGIN
    binds := wwv_flow_utilities.get_binds('select :P1_TEST from dual');
    FOR i IN 1 .. binds.count
    LOOP
      dbms_output.put_line(binds(i));
    END LOOP;
  END;
  /
  
  anonymous block completed
  :P1_TEST

  But I would not use these functions without papers as those who can change or there is no future versions APEX.
  Is there a documented function or the custom function that do the same thing as wwv_flow_utilities.get_binds?

  Some old basic example code of my friends. Also the media getting the bind variable of PL/SQL code blocks anon.

• Preserve Bind values in the SQL worksheet

  Hello

  When you run the SQL statements with var/binding settings, SQLD can persist values entered the tool reboots?

  Is there a preference that controls this?

  Java (TM) Platform	1.7.0_71
  Oracle IDE	4.0.3.16.84
  Support for versioning	4.0.3.16.84

  Never mind. Found, he looked at me, but I was blind.

• 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;
  .........
  .........

  However, when I replace the bind variable with the values in the collection, then it works:
  

  ..........
  ..........
  ..........
  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;
  ..........
  ..........

  Please suggest if there is something wrong in my code first. I tried, but could not get any inadequacy.

  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).

• Reference SQL Loader Bind Variables in the when Clause

  Support for SQL: SQL * Loader: version 8.0.6.3.0 (don't ask, it runs on Oracle EBS 11i...)
  
  I have a case where my sample data looks like:
  

  HD00100001002
  SM00100002CHAPS   99999999999                     20120906GBP0000000000001000000000001

  and another file
  

  HD00100001001
  SM00100002GBP0000000000001000000000001

  Essentially, I need to apply another "IN" clause for each record of SM depends on the ack_type (char 13 on HD recording), either 1 or 2
  
  I tried setting up the ack_type with a variable binding but find how to reference.
  
  Example of control file:
  

  --  $Header: test.ctl
  --
  
  LOAD DATA
  REPLACE
  
  -- Record Type HD : File Header
  INTO TABLE  test_table
  WHEN rec_id_no = 'HD'

   ack_type               POSITION(13:13) ":ack_type",
   co_id                  POSITION(14:21) CHAR,
   dept_id                POSITION(22:24) CHAR,
   btch_no                POSITION(25:36) CHAR,
   trans_id               POSITION(37:42) CHAR)
  
  -- Record Type SM : File Summary
  INTO TABLE test_table
  WHEN rec_id_no = 'SM' and :ack_type = '1'
  TRAILING NULLCOLS
  (rec_no                 RECNUM,
   hdr_line               CONSTANT 'L',

   amount                 POSITION(14:26) CHAR,

  The code above does not work, it is said that: ack_type is not recognized. Is there a way to do it, given the former character of the SQL Load version?

• Using a Bind Variable in the FROM of a SQL statement part?

  Hi all
  
  I have a problem, I am trying to execute a SQL statement. However, I need the FROM part of the SQL statement in a variable binding. This is because the end user will have to choose between 2 views of database.
  
  I tried this:
  Select CON_ID from: P23_DB_NAME where CON_LEGACY_ID =: P23_CONLEG_NO
  
  I had no chance. The error I got was,
  '+ The query cannot be parsed in the generator. If you believe that your request is
  syntactically correct, choose the generic "columns" box below the
  the source of the region without analysis.
  "ORA-00903: invalid table name +".
  What makes sence, but now I'm a little stuck.
  
  Does anyone have ideas for a workaround?
  
  Thanks in advance.
  -N.S.N.O.
  

  The example I gave you is quite simple. You must take some time to study it to see where you need to be very careful what put you where. Now, of course your example does not work becaues you have several errors. It will work for you:

  DECLARE
     x   VARCHAR2 (4000);
  BEGIN
     x := x || 'SELECT CON_ID FROM ';
     x := x || :p23_db_name;
     x := x || ' WHERE CON_LEGACY_ID = ' || :p23_conleg_no;
     RETURN (x);
  END;

• Oracle.ManagedDataAccess gives ORA-01006 if there is bind variables in the comments, but only on the lines.

  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.

• bind variables in pl/sql static

  Hello world.

  I tried to find info related to the execution of pl/sql query steps, but cannot. Optimizer does use the values of real variables in pl/sql to generate the exec. plan? Or it will be generated only once when the function performed the first time?

  http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14261/overview.htm#sthref145

  "When you embed an INSERT, UPDATE, DELETE or SELECT SQL statement directly in your PL/SQL code, PL/SQL transforms the variables in the WHERE clauses of the VALUES to automatically bind variables. Oracle can re-use these SQL statement every time the same code is executed. To execute statements similar with different values of variables, you can save the analysis of overhead by calling a stored procedure that accepts parameters, and then issues the declarations with the parameters substituted in the appropriate places. »

• 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 https://community.oracle.com/message/2746551#2746551 ( )

  @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.    https://community.oracle.com/message/10632314#10632314

  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.

• 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.

• 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, Steve

  Steve,
  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.

• VO with bind variable defined in SQL is not updated correctly

  Hi Experts,
  
  I have a simple question here, could you please help answer? Thank you very much!
  
  I have 2 pages, the first page displays an employee table, the second page shows a few details to the selected employee. When to choose a single employee and click the details button I can be naviaged to the second page and see the details for the selected employee. The vo used on the second page uses a connection variable called "empId" thing for a 'adf.context.pageFlowScope.empId' pageFlowScope value, and this value pageFlowScope will be filled to the empId selected detail button actionListener during execution).
  
  The question is, now first navigation is ok, the details of the page can display the correct information for the employee selected on the page of the employee, but when browsing back and choosing another employee, and then again click the details button, the details of the page is NOT updated, it still shows the initial information for the selected employee. I debug the actionListener in support bean and the second selected empId passed to pageFlowScope.empId, the link in the t variable should get the new value, right? But why the second page gets no updates (request using the new value of the bind variable)?
  
  Thank you!

  In theory, if you expose specific objects of customer to your business (for example pageflowscope) service layer, you may miss 1. test driven development assistance (case of unit test can fail) 2. Customer service of independent business etc... :)
  To respond to your request try to call TargetPagesVO.execute () before the second page (by program or activity method)

• 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 you

  Yes, they are supported.
