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

• Use of bind variables in the repository

  All,
  
  Our client has a requirement that they need the sales this year of sales vs. last year passing year as a guest.
  I can't use BI built in function to get early start or this year last year because our calendar dates are not standard. So I have to this day of dim query table to see e.g. for whats 2010 is the start date and so on...
  
  To do this, I created a variable repository to hold these values using SQL. I want to know is can I use a binding to this SQL variable so that when the user passes year I can feed that year in this SQL and it will provide me with correct start and the end date for this year and last year.
  
  Thanks in advance

  Yes. We can pass a value to what the user selects the guest. To do this you have create a session variable with "enable any user to set the value". Prompt properties for the year column choose "Ask the Variable" for whole Variable. And the use of content filtering year = ' valueof (NQ_SESSION.myVariable).

  Let me know if it worked.

  Kind regards

• 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.

• The use of bind variables in the HTML source region

  I have problems integrating an element variable in an embedded HTML string that should popup a video mode when the button is pressed.
  
  Element 1 works very well and it's what I want to accomplish with point 2, but when I pass: p1_url, it does not work even if the content of the equivalent of two text boxes.

  Hi fac586:

  You who modifies the code to use * $('_#foo').html ($v ('P1_SAVED_ITEM2')); * ?? If so, I think that solved my problem here. I tested it and it seems to work everytime now. Thank you

  Yes. It was very late and I could not spend more time on a detailed explanation. foo is the static region ID, I assigned to the masked area of the HTML to use as a jQuery selector.

• Ensure this soft analysis the use of Bind variables

  Hi Experts,
  
  I have a request when the query is prepared dynamically in Java code and if I take the query and run it from SQL Navigator, it takes a long time to prepare the statement and then execute it quickly. I think we can use dynamic SQL statements and bind variable to improve performance here. However, I tried to do a PDS to check my understanding. I created 2 procedures
  
  1. mode of operation

  CREATE OR REPLACE PROCEDURE sp_static
  (id IN NUMBER, 
   name in VARCHAR2)
  IS 
  TYPE r_curs_type is REF CURSOR;
  C1 r_curs_type;
  BEGIN
  
  OPEN C1
  FOR
  SELECT * FROM TABLE WHERE columname = id
  
  CLOSE C1;
  
  END;

  2. mode of operation

  CREATE PROCEDURE sp_dyanmic
  (id IN NUMBER, 
   name in VARCHAR2)
  IS 
  TYPE r_curs_type is REF CURSOR;
  C1 r_curs_type;
  BEGIN
  
  OPEN C1 FOR 'SELECT * FROM TABLE WHERE columnanme = :U1' 
  USING ID;
  
  CLOSE C1;
  END;

  To my amazement, there is no difference in the duration of execution of these procedures when I ran the with multiple entries.
  
  Please note-
  1. I have not access to trace files :-(
  2. I want to just make sure there will be improved performance before starting the real work, given that some efforts provided by moving the logic of all its activities inside and the use of bind variables.
  
  If you can suggest a strategy to ensure performance gains, it will be extremely useful...
  
  Thanks in advance!
  Concerning

  Hello

  (1) it's true, procedure 1 also uses a variable binding
  (2) you seem to be confused about the very basic concepts here

  Dynamic SQL is something like this:

  create or replace FUNCTION f (l_table_name VARCHAR2) RETURN NUMBER
  IS
    l_result NUMBER;
  BEGIN
    EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || l_table_name  INTO l_result;
    return l_result;
  END;
  

  In this example, since you do not know the name of the table to the execution table, everything you can
  is dynamic SQL. As you can see, neither of your two procedures is like that.

  Dynamic SQL is used when you do not know what columns you want to select, or who
  etc. to the execution table. You can also use dynamic SQL statements to force analysis. You can not use
  to avoid parsing, binding or not binding.

• 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.

• The use of bind variables (in &amp; out) with sql dynamic

  I have a table that contains code snippets to make postings on a set of pl/sql database. what the code does is basically receives an ID and returns a number of errors found.
  To run the code, I use dynamic sql with two bind variables.
  
  When codes consists of a simpel query, it works like a charm, for example with this code:
  

  BEGIN
     SELECT COUNT (1)
     INTO :1
     FROM articles atl
     WHERE ATL.CSE_ID = :2 AND cgp_id IS NULL;
  END;

  However when I get to post more complexes that must perform calculations or run several queries I run into trouble.
  I have boiled down the problem into that:
  

  DECLARE
     counter   NUMBER;
     my_id     NUMBER := 61;
  BEGIN
     EXECUTE IMMEDIATE ('
        declare 
           some_var number;
        begin
        
        select 1 into some_var from dual
        where :2 = 61; 
        
        :1 := :2;
        end;
  ')
        USING OUT counter, IN my_id;
  
     DBMS_OUTPUT.put_line (counter || '-' || my_id);
  END;

  This code is not really make sense, but it's just to show you what is the problem. When I run this code, I get the error
  ORA-6537 ON bind variable linked to a position IN
  
  The error doesn't seem wise,: 2 is the only one IN bind variable and it is only used in a where clause clause.
  As soon as I remove this where clause, the code works again (giving me 61-61, in case you want to know).
  
  Any idea what goes wrong? I just use bind variables in a way that you're not supposed to use it?
  
  I'm using Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit

  Correction. With immediate execution , the binding is in position, but binds do not need to be repeated. My statement above is incorrect...

  You must link only once - but bind by position. And the connection must correspond to the use of the variable binding.

  If the connection never variable assigns a value in the code, link by in.

  If the binding variable assigns a value in the code, link as OUTPUT.

  If the binding variable assigns a value and is used a variable in another statement in the code, link as IN OUT.

  For example

  SQL> create or replace procedure FooProc is
    2          cnt     number;
    3          id      number := 61;

    5          execute immediate
    6  'declare
    7          n       number;
    8  begin
    9          select
   10                  1 into n
   11          from dual
   12          where :var1 = 61;       --// var1 is used as IN
   13
   14          :var2 := n * :var1;     --// var2 is used as OUT and var1 as IN
   15          :var2 := -1 * :var2;    --// var2 is used as OUT and IN
   16  end;
   17  '
   18          using
   19                  in out id, in out cnt;  --// must reflect usage above

• The use of bind variables in dynamic query created for Ref Cursor

  Hello
  
  I'm in a situation where there is a Ref cursor to which the query is built execution based on a loop. This is why the number of links would be known until the program runs.
  The application is currently using literals instead of bind variables.
  
  code snippet of the above is
  strSql: = "select * from emp where 1 = 1 and ().
  
  loop cursor1
  If cond is true then
  strSql = strSql | "ename = ' |" Cursor1.ColumnName;
  end loop;
  
  Open cursor2 for strSql;

  Here is the code I have my trying to change literal-based link to the base.

  What do you mean by "based bind?

  who, what, how determines the values to be 'bound '?

  He's referring to the coding style. He is currently using concatenated literal, and the goal is to change it to use the bindings.

  If I understand this it is known as method 4 dynamic SQL and requires DBMS_SQL. There are examples autour but they vary according to the type of statement being generated - SELECT statements require column lists to be parsed, unlike the INSERT/UPDATE/DELETE.

  This came up recently on my current project and I hit a demo. Here a table of names and values accepted procedure and had to build these in a single WHERE clause along the lines of

  AND t_names(i) = t_values(i)
  

  for an undetermined number of elements in the array. For this demonstration, I used a table that we called "attribute" (don't ask) which has columns including 'attribute_id' and 'name', and I need to build a query along the lines of

  select description from attribute where attribute_id = :b1 and name = :b2
  

  by the way '1012' and 'ISIN' respectively. (I use a table better and after a CREATE statement for her but I have to rush right now, sorry).

  declare
     k_sql_base        constant varchar2(500) := 'select description from attribute';
  
     t_names           constant varchar2_t := varchar2_t('attribute_id',  'name');

     l_cursor_handle   integer;
  
  begin
     -- Construct the SQL statement with column names and bind variables e.g.

     dbms_output.put_line('SQL statment = ' || l_sql);

     -- Associate the 1st column of output with variable l_value - required for SELECT statements:

     -- dbms_sql.column_value actually extracts the value into a specified variable, which can be different.
     -- All examples in the documentation pass a local variable without further comment, so not entirely clear what this does other than set the output datatype.)
     dbms_sql.define_column(l_cursor_handle, 1, l_value, 4000);
  
     -- Now go through values array binding actual values to :bn variables in the cursor (similar to USING clause of EXECUTE IMMEDIATE)

• 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.

• 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.

• 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.
