• 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;
  
  How to use links in the example above.

  Hello

  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');
     t_values          constant varchar2_t := varchar2_t('1012',          'ISIN');
  
     l_sql             varchar2(500) := k_sql_base;
     l_rows_fetched    integer := 0;
     l_value           varchar2(4000);
  
     l_cursor_handle   integer;
  
  begin
     -- Construct the SQL statement with column names and bind variables e.g.
     -- 'select description from mars.attribute where attribute_id = :b1 and name = :b2'
     for i in t_names.first .. t_names.last loop
        l_sql := l_sql ||
           case i
              when t_names.first then ' where ' else ' and '
           end ||
           t_names(i) || ' = :b' || i;
     end loop;
  
     dbms_output.put_line('SQL statment = ' || l_sql); 
  
     -- Parse the statement we built above (the remaining steps require a parsed cursor):
     l_cursor_handle := dbms_sql.open_cursor;
     dbms_sql.parse(l_cursor_handle, l_sql, dbms_sql.native);
  
     -- Associate the 1st column of output with variable l_value - required for SELECT statements:
     -- (actually the 3rd param here 'column' seems to be only used to get a datatype, in this case we want a string -
     -- 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)
     for i in t_values.first .. t_values.last loop
        dbms_sql.bind_variable(l_cursor_handle, ':b'||i, t_values(i));
        dbms_output.put_line('Bound :b'||i || ' as ' || t_values(i));
     end loop;
  
     -- Open the cursor and fetch the result (no loop here because we are expecting a single-row result):
     l_rows_fetched := dbms_sql.execute_and_fetch(l_cursor_handle);
  
     -- 'Returns value of the cursor element for a given position in a cursor'

• Look up values in the query are retained when a query Panel is used in popup

  We used a panel of popup for the search request. When popup is opened again, the search criteria previous values are preserved. They may not get deleted if pop up attribute of content delivery is lazy not cached. Is it possible to clear these values or is this a bug of frame work?

  This is normal and expected behavior. The query pattern keeps the criteria values, otherwise the query Panel would be empty if you refresh the it by PPR. Depending on the configuration of the ViewCriteria and research underlying link, values can be retained even if you leave the page, and then open the page again.

  If you want to clear the query criteria when you open the context menu, you can implement a PopupFetchListener for the popup. PopupFetchListener runs every time when the popup is open. Here, you can get and to reset the component query programmatically. Check out this blogpost for more details how to reset:

• How to bind selectBooleanCheckbox in DB table

  I have selectBooleanCheckbox in table ADF that comes with the base data type of the column NUMBERtable.
  
  The JSF Page Code:

  <af:selectBooleanCheckbox value="#{row.bindings.PercentFlag.inputValue}"
                           label="#{row.bindings.PercentFlag.label}"
                           id="it7">                                        
  </af:selectBooleanCheckbox>

  Pagedef file code:

   <button IterBinding="MeasureConditionalFormatVOIterator" id="PercentFlag"
              DTSupportsMRU="false" StaticList="true">
        <AttrNames>
          <Item Value="PercentFlag"/>
        </AttrNames>
        <ValueList>
          <Item Value="1"/>
          <Item Value="0"/>
        </ValueList>
      </button>

  When I try to save this value in the database it throws the error:
  Error: PercentFlag: 'false' must be a signed decimal number.
  
  Could someone let me know how to bind the value 1/0 with db table.
  
  Thank you...
  
  Published by: broke on 9 February 2012 06:10

  The entity attribute 'PercentFlag', just change the type BigDecimal (or whatever it is at the moment) to Boolean. JDeveloper will automatically change the column type of database in BITS, which allows that the values 0 (false) and 1 (true).
  From there, once you drag the PercentFlag (or the entire table) in the data source to a page, JDeveloper will automatically add the column as a SelectBooleanCheckBox.
  I also recommend to set the default value for the attribute of the entity to 0 or 1. If the value is null and that the record is loaded on a page and validated, the record is marked as dirty since the SelectBooleanCheckBox knows only 2 values, true (1) or false (0).

• binding values in Multiselect guest-urgent

  Hi guys,.
  I have a problem. I need to constrain the values in a guest of multiple selection based on the values of an another command prompt.
  Now the problem is, the multiple selection prompt is binding values, but when I search another value (which must have been limited) it appears.
  
  I tried using variable presentation in the SQL for the guest. But also, it does not work.
  
  Any help please...
  
  Kind regards
  Ronnie

  Do you use two different guests or a prompt with two selections of column inside. If it's a prompt then you cannot use pre. variable in the sql query. given that the variable will be set only after you press 'go '. create two guests. one with pre. variable. then use this variable in the second line. in your dashboard you must select a value from the first fast b4 using your multiple selection prompt.

• How to assign values to the application points to leave on a table

  Hello

  I have a FORM on a table with two or three elements. How to assign values to the elements of the application with the values in the elements of form, every time the value of the element is entry, change or page is sent?

  I created a dynamic action to the region level with Event - change to run the suite of PL/SQL, I tried with 3 different ways in PL/SQL, as shown below, but it didn't work.

  BEGIN

  : APP_FY: =: P1_FY;

  END;

  BEGIN

  APEX_UTIL. SET_SESSION_STATE ('APP_FY', v ('P1_FY'));

  : APP_FY: =: P1_FY;

  END;

  BEGIN

  APEX_UTIL. SET_SESSION_STATE ('APP_FY', v: P1_FY);

  END;

  Then I created an action dynamic at the ITEM level with change event to run the suite of PL/SQL and tried with PL/SQL, as shown below, but it didn't work.

  I need to assign values to the elements of the request form as these elements of the application will be used in many other pages in the application. How to I get there?

  Thank you.

  If a dynamic action of PL/SQL execution, you must send your list of page elements in the parameter "Elements of Page to submit.

  See the section 'run pl/sql' for this post.

  If the page is submitted, the elements of the page will be automatically set to session state, and you can have a page process make the code you have.

• How to store values of TextField in table

  Hello

  I am trying to write a code to store values of TextField in a table. I know how to convert entire TextField. But after that, we have different integer variables. I can't understand how to store values of these whole different variables in a table by using a loop.

  public class ArrAvg {}

  Public Shared Sub main (String [] args) {}

  int arr [10] = new int [10];

  inputNumbers (arr);

  }

  val2 = Integer.parseInt (value2);

  val3 = Integer.parseInt (value3);

  for (i = 0; i < 10; ++ I) {}

  I have stored text field in ArrayList so i should traverse the ArrayList. But when i am converting the contents of Arraylist into integer, i am getting type mismatch despite the fact that my ArrayList is of String type.
  
  
  

  Yes - the ArrayList to string but you create an iterator for object

  Iterator itr = al.iterator (); getting iterator of arraylist to iterate through the items

  This method of "al.iterator" () returns the iterator; for your use case E-online String. See the API

  https://docs.Oracle.com/javase/8/docs/API/Java/util/ArrayList.html

  You set it to 'Iterator' which is NOT a generic, so only objects are returned.

  So get back to string.

  Create your instance of the iterator Iterator.

  Is it possible to avoid "iterator"?

  Why avoid it? Just use the appropriate iterator.

  The class has a 'size' and a method 'get (int index) '. So you can use a loop from zero to the 'size', but simply use the iterator.

• How to transfer values to the popup while the bean in application scope?

  Hi all

  I use JDeveloper 11.1.1.4

  My scenario is that I have a < af:popup > with a component of < af:outputText >.

  I need pass values of output text dynamically according to the scenarios.

  My grain of support is application scope . So I'm not able to pass values using get and methods.

  My Design as,

  < af:popup id = "p1" contentDelivery = "lazyUncached" >

  < af:outputText value = "#{managedBean.getDynamicText}" id = "ot1" / > "

  < / af:popup >

  Now I run the application I'm not get all values in text during debugging output, I am able to set the value, but it didn't reflect on the page.

  How to transfer values to the popup while the bean in application scope?

  Thank you...

  At the bean, why don't you set the value to a variable pageflowscope and point the outputtext popup to the pageflowscope variable?

  () .getpageflowscope, set AdfFacesContext.getCurrentInstance ("nomvar", value);

• EA4: enter the bind values dialog box

  For some of my reports, I bind values and the user is prompted to accept the incoming. Everything works well, but is this normal when you enter (say 4) in the box and press on enter, accept the dialog that CR? I would normally expect the button apply be hurry to hit the Enter key. This is expected behavior?

  REDA

  Yes, this is normal behavior even in versions of pre SqlDev4EA1.  It allows you to enter as a bind value multiline text.  All links are treated as data of type varchar, so if you use it as part of a numeric or date, you must explicitly convert the appropriate data type.

  Well you do almost everything bad that could be hurt.

  Here is the code that works to insert data into your table (the procedure is not even necessary).

  declare
  p_sl_num NUMBER := 1001;
  p_description VARCHAR2(50) := 'Testing Val1';
  inval1 test_type1 := test_type1();
  inval2 test_type2 := test_type2();
  begin
  inval1.extend();
  inval1(1) := test_object1('testx1', 'testx2', 'testx3');
  inval2.extend();
  inval2(1) := test_object2('testy1', 'testy2', 'testy3');
  
  INSERT INTO test_object_tpe
  (
  sl_num,
  description,
  main_val1,
  main_val2
  )
  VALUES
  (p_sl_num, p_description, inval1, inval2);
  commit;
  end;
  /
  

  See example 5-15 making reference to an element of nested Table Chapter 5 using PL/SQL collections and records in the PL/SQL doc
  http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/Collections.htm#CJABEBEA

  1. you don't even have the procedure because it is a simple INSERTION in the table you can do directly (see my above code)

  inval1(1).val1 := 'testx1';
  

  Since you have not yet created all the elements, there is no element 1 "inval1". You need EXTEND the collection to add an element

  inval1.extend();
  

  And then, there is an empty element, but "inval1" is a container for objects of type 'test_object1' not for scalars as "val1", "val2", and "val3".
  If you can not do

  inval1(1).val1 := 'testx1';
  

  You must create an instance of 'test_object1 '.

  inval1(1) := test_object1('testx1', 'testx2', 'testx3');
  

  And so on for the other collection

  You don't need the procedure (as my code example shows), but once you fill in the variables correctly it will work.
