• 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.

• Problem with Bind variable cannot be changed.

  Hi all
  I use Jdev 11.1.2.3.0. In my VO, I created a Bind Variable and set it NOT UPDATABLE. Then, I created a display with some other Variables Bind criterion.
  I use this criterion to display on a search page, but when running, I see also an inpunt for the defined variable NOT UPDATABLE text and I can't change its value.
  Of course, if I try to change the value, and I do research, I get an error.
  
  It is the source of the VO:
  
  < variable
  Name = "UlssVar".
  Type = "where".
  Type = "Java.lang.String"
  IsUpdateable = "false" >
  < TransientExpression > <! [CDATA [adf.context.current.sessionScope.get ('ulss')]] > < / TransientExpression >
  < / variable >
  
  Is this a bug of the ADF?
  I thank in advance.

  Hello

  try selecting the variable binding and open the property inspector, under the guidance of the user interface, set the flag of 'view' to hide. This should hide it (no bug for this reason)

• Problem with bind variable and as operator usage

  Hi all

  I use JDeveloper Version - 11.1.2.4.39.64.36.1 .

  
  

  While implementing the search functionality in the hierarchical Viewer, I created a link in the underlying t variable, created to find, due east of the request-

  
  

  SELECT XxamAnkitObjects.ID,

  XxamAnkitObjects.OBJECT_NAME,

  XxamAnkitObjects.OBJECT_TYPE,

  XxamAnkitObjects.PARENT,

  XxamAnkitObjects.PARENT_ID,

  XxamAnkitObjects.PARENT_TYPE

  OF XXAM_ANKIT_OBJECTS XxamAnkitObjects

  WHERE object_name like ' %: o_name ".

  What I'm trying to accomplish here, it is that the input provided by the user in the search box must match with the object_name in the table.

  During execution, I met the following error (from newspapers WLS)-

  < QueryCollection > < buildResultSet > [598] java.sql.SQLException: try to set a parameter name that does not intervene in the SQL: o_name

  at oracle.jdbc.driver.OraclePreparedStatement.setNullAtName(OraclePreparedStatement.java:5384)

  at oracle.jdbc.driver.OraclePreparedStatementWrapper.setNullAtName(OraclePreparedStatementWrapper.java:1451)

  The following query has been generated during the operation of a research-

  < ViewObjectImpl > < buildQuery > [593] SELECT XxamAnkitObjects.ID, XxamAnkitObjects.OBJECT_NAME, XxamAnkitObjects.OBJECT_TYPE, XxamAnkitObjects.PARENT, XxamAnkitObjects.PARENT_ID, XxamAnkitObjects.PARENT_TYPE XXAM_ANKIT_OBJECTS XxamAnkitObjects WHERE object_name like ' %: o_name ".

  < ViewObjectImpl > < bindParametersForCollection > [594] params for ViewObject Bind: [model.vo.ObjectNameSearch] AppModule.ObjectNameSearch1

  Advice kindly the way ahead.

  Best regards

  Ankit Gupta

  The problem is that you used quotes around the variable binding. Try

  SELECT XxamAnkitObjects.ID,
         XxamAnkitObjects.OBJECT_NAME,
         XxamAnkitObjects.OBJECT_TYPE,
         XxamAnkitObjects.PARENT,
         XxamAnkitObjects.PARENT_ID,
         XxamAnkitObjects.PARENT_TYPE
  FROM XXAM_ANKIT_OBJECTS XxamAnkitObjects
  WHERE object_name like '%' || :o_name || '%'
  

  A note: this type of query will do a full table scan, as the searches with wildcards to the left cannot use a regular index. If you have multiple lines, this will impact on the research persormance hughe!

  I have a big script with multiple INSERT and DELETE statements. I have been asked by DBA to use bind variables rather than direct assignment parameter values in which the condition.

  Impossible.

  Use of variable bind from a client means:
  (1) customer create a unique SQL cursor with bind variable, for example INSERT INTO FOOTABLE VALUES (: 1,: 2: 3)
  (2) customer from a loop of data read
  2.1) reading the customer data (from file, network, device, whatever)
  customer liaison variables 2.2) cursor (assigning values to 1 to 3 SQL cursor variables)
  2.3) client running the cursor
  line insertions 2.4) database
  loop repetitions of 2.5) client for all data
  (3) customer closed the SQL cursor

  This can be done using a SQL script - as a SQL script is not a loop where a single insertion cursor is used. It's a unique script with 100 or 1000 of SQL insert statements. Where each insert statement will result in a cursor SQL must be created.

  SQL * also does not support the approach of customer liaison above variable. It is a command line interface very PRIMITIVE and unsuitable for running scripts from loading/data entry.

  In your case - the right approach would be to have the data into a CSV file, and then load this file using SQL * Loader... where this software will use customer approach above (in fact he still does better because it uses in bulk link and link not row as described above).

• Query report back "No data found" with bind variables

  I put a simple query in the report query:
  
  Select "bluefish". 'name' as 'name',
  "bluefish". "" primary_flag "as"primary_flag. "
  "bluefish". "" status "than"status. "
  "bluefish". ' ' ID ' as 'ID' of "bluefish" "bluefish" where "bluefish". "" ID "=: P3_XPRINTID
  
  When I test the query, the data is returned. However, when I try to run the query using the "Test report" button, I get an error 01403 no data found. If I replace the link with an explicit value variable, the report runs.
  
  Anyone have any ideas as to what is causing this problem? I use the generic report layout, with different types of output. I'M editting the query and set the binding variable before test report (otherwise, the query is not executed).
  
  Charles

  In fact the report would go - unlike other products of Oracle who complain about a missing binding variable, Apex is not complaining but interprets as a null value. So if you hurt typed the name of your variable, you are never alerted to it.

  Check the Session window to make sure that it is a value - the most common questions are that you named the wrong variable in the query or your item has no value in session state again.

• Need help with Bind variable in AF LOV query

  Hello
  
  I have a problem with the binding variable, if I use bind variable in the VO LOV query then my result does not come, if he has do not bind variable it works fine and if I use the variable binding in the LOV search option then it works fine but if I hide the bind variable and set the value in the prepareSesstion AM method the LOV does not return any value. I try to return the values that also all values are also coming, but these values are not the attribute query AF setting.
  
  Query is:
  
  Select substr(d.description,0,40) description
  cm_system_users has
  b cm_user_responsibilities,
  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 of d.arguments_flag
  
  FOLLOW the method:
  
  CmProcessViewImpl vo = getCmProcessView();
  String nt_login = getUserPrincipalName();
  vo.setNamedWhereClauseParam ("B_NT_LOGIN", nt_login.toUpperCase ());
  vo.executeQuery ();
  
  Can someone help me with this. It is urgent for me.

  It's a bit underdescribed. IIUC, the purpose of the notice is used as a target for a correct view accessor? (Otherwise, you will have to be more explicit about what you mean by "LOV query".

  If I'm right, there are two possibilities:

  (1) you use an instance of VO in a module shared application instance. If so, make sure that your code is in the prepareSession() for the class of application that module if it is dependent on session (as seems to be below), you must make sure that the module of the application instance is shared in the session scope.
  (2) you have based the view accessor directly on the definition of the VO. This creates an anonymous instance of VO; I don't think there is a way to use prepareSession() to set a variable of liaison on such a forum (which will not be created until the accessor is first used). Pourriez be able to shoot with to put a similar code in the view object create() method class, but I've not tested this.

  If your code is in your module class application primary (as opposed to the class for a shared of AOS instance), the problem here is that getCmProcessView() returns the instance of VO data module of this application instance design-time model, which is never used by accessors of the view.

  Also, why do you need to do this in prepareSession() rather than at the level of the accessor to view? I believe you can get the user name (for the view accessor) with the groovy expression

  viewObject.DBTransaction.session.userPrincipalName

  or maybe just

  DBTransaction.session.userPrincipalName

  (despite this DBTransaction involving, it returns the username web app, not the DB user name).

  It is a declarative 100% solution, if you don't count the Groovy expression as not declarative.

  If you are afraid of a user who is running the LOV (somehow) before the value of the bind variable is preparing, just make sure that the binding variable is marked "required."

• Estimates of cardinality for index range scan with bind variables

  Oracle 11.2.0.4

  I am struggling to explain that the cardinality estimates for a scan of the index systematic range when using the bind variable.

  Consider the following query:

  SELECT /*+ INDEX(t1) */ *
  FROM   t1
  WHERE  source_id <= ?;
  
  

  Cardinalities for the INDEX RANGE SCAN and ACCESS of the TABLE are the same for different literal predicates, for example, source_id < = 5:

  ------------------------------------------------------------------------------------
  | Id  | Operation                   | Name | Rows  | Bytes | Cost (%CPU)| Time     |
  ------------------------------------------------------------------------------------
  |   0 | SELECT STATEMENT            |      |    50 |   350 |    12   (0)| 00:00:01 |
  |   1 |  TABLE ACCESS BY INDEX ROWID| T1   |    50 |   350 |    12   (0)| 00:00:01 |
  |*  2 |   INDEX RANGE SCAN          | IX1  |    50 |       |     2   (0)| 00:00:01 |
  ------------------------------------------------------------------------------------
  
  Predicate Information (identified by operation id):
  ---------------------------------------------------
  
     2 - access("SOURCE_ID"<=5)
  
  

  If a variable binding is used instead of a literal, the overall selectivity is 5%. However, why the optimizer based on CSSTidy gives a cardinality estimated 11 for the scan of the index systematic range? As with the predicates literal, surely the cardinalities of the index range scan and access table should be the same?

  ------------------------------------------------------------------------------------
  | Id  | Operation                   | Name | Rows  | Bytes | Cost (%CPU)| Time     |
  ------------------------------------------------------------------------------------
  |   0 | SELECT STATEMENT            |      |    50 |   350 |     5   (0)| 00:00:01 |
  |   1 |  TABLE ACCESS BY INDEX ROWID| T1   |    50 |   350 |     5   (0)| 00:00:01 |
  |*  2 |   INDEX RANGE SCAN          | IX1  |    11 |       |     2   (0)| 00:00:01 |
  ------------------------------------------------------------------------------------
  
  Predicate Information (identified by operation id):
  ---------------------------------------------------
  
     2 - access("SOURCE_ID"<=TO_NUMBER(:A))
  
  

  Unit test code:

  CREATE TABLE t1
  ( id NUMBER
  , source_id NUMBER
  );
  
  CREATE INDEX ix1 ON t1 (source_id);
  
  INSERT INTO t1
  SELECT level
       , ora_hash(level,99)+1
  FROM   dual
  CONNECT BY level <= 1000;
  
  exec DBMS_STATS.GATHER_TABLE_STATS(user,'T1')
  
  EXPLAIN PLAN FOR
  SELECT /*+ INDEX(t1) */ *
  FROM   t1
  WHERE  source_id <= 5;
  SELECT * FROM TABLE(dbms_xplan.display);
  
  EXPLAIN PLAN FOR
  SELECT /*+ INDEX(t1) */ *
  FROM   t1
  WHERE  source_id <= :a;
  SELECT * FROM TABLE(dbms_xplan.display);
  
  

  There are various places where the optimizer uses an assumption, and lie unpeekable (and of Villa "unknowable value") introduced guess.

  For unpeekable binds the conjecture for column<= {unknown}="" is="" 5%="" for="" table="" access="" (hence="" 50="" rows="" out="" of="" 1,000),="" but="" it's="" 0.009="" for="" index_column=""><= {unknown},="" which="" means="" i="" was="" expecting="" to="" see="" 9="" as="" the="" row="" estimate="" on="" the="" index="" range="">

  I just ran some quick tests, and EXPLAIN the PLAN seems to just use 0.011 selectivity in this case (in different versions of Oracle) although if we do the bind variable unpeekable at run time (and sample dynamic block etc.) optimization for execution is 0.009%.

  Update: and this is a very old reference to the 0.009 (and 0.0045 for ' between the ' when it is applied to a clue: cost based Oracle - access Chapter 4 single B-tree )

• R12 Extension with bind variables-how VO EO

  Hello

  I extended an APInvDistAllVO view object by adding two fields which are functions. Basically, in the invoice approval screen, I want to add two fields where the distribution of the invoice is shown.

  the SQL contained in jdeveloper when you extend the VO object is different from the query, what I see in the invoice approval page by clicking on the APInvDistAllVO link. There are two bind variable: 1 = invoice_id and: 2 = line_number being added dynamically.

  After the extension of the view object, the invoice distribution line is displayed as no record found. In my opinion, it is due to not having bind variables does not correct parameters being passed, and under this point of view object is an object depending on the invoice header record.

  Will be very grateful if someone can provide the way forward in dealing with this situation.

• 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.

• Problem using bind variables in shared components report queries

  Greetings,
  
  I use APEX 4.0.1.00.03 and BI Publisher 10.1.3.4.1.
  
  In the APEX, I try to create a report query that uses bind variables in the where clause. I have a page that contains a button and a text element (P1_ID). The button is used to call the report. I went the shared components and created a new report query. Here is the text of the code.
  

  select violation_date
  , violation_type
  , nvl(:P1_ID,'zzz')
  from edd_procard_violations
  where upper(card_holder_id) = upper(:P1_ID)

  I also have Session State to enabled and have added the P1_ID in the area of 'State of Session' under the query.
  
  When I change the query, and click on the 'Set Bind Variables' button, I get a field where I can enter a value for: P1_ID I enter a value that should return lines, but when I click on the button "Test query", I get no rows returned. If I comment on where clause and test the query, even once, I get all rows in the table. You'll notice in my query I have included nvl(:P1_ID,'zzz'). When I run the query, without where clause, the returned value is always "zzz" indicating that: P1_ID is null.
  
  No idea what I am doing wrong?
  
  Thank you very much.
  Larry

  Hello Larry,.

  Looks like the wizard to create a report query in the shared components has a bug related to bind variables. I was able to reproduce your problem. Just create the query using the link variable, check the box to include session state, add the item and create the query. When you use the report query to download the report, where the your clause will work fine.

  Thank you

• IN construction in the clause WHERE of VO with bind variable

  Hello
  With the help of JDev 11.1.1.3.0.
  I have a SQL according to VO following where clause ' WHERE some_nbr IN: inSomeNbrStr'
  -l' some_nbr attribute is of type oracle.jbo.domain.Number.
  -variable binding inSomeNbrStr is of type String.
  I'm assuming that this variable linking parameter to for example. "101, 102' or '(101, 102) ' before the execution of the query might work.
  "However, I get ' ORA-01722: invalid number." Other than the substitution of executeQueryForCollection() and manipulate by program the
  query is - anyone know a more declarative way to achieve this?
  Thank you
  Kenneth

  Hello

  You "MOUNT" the binding variable to get the values separated by commas.

  See this article (Search Using Comma-Separated bind string for the Variable in the list) on how to achieve this.

  It has been developed over 10g. But I think it will hold good for 11g as well.
