• Create the object type with a member function that returns an array of the object type

  Hello

  Is possible to compile code like this in Oracle SQL?

  CREATE OR REPLACE TYPE type_obj IS OBJECT (
    MEMBER FUNCTION f RETURN table_obj
  );
  
  CREATE OR REPLACE TYPE table_obj AS TABLE OF type_obj;
  
  

  In Java, it would be possible.

  Thanks in advance

  Circular dependencies must be resolved by means of REF pointers and incomplete type definition.

  See: Oracle objects management

  CREATE or REPLACE TYPE type_obj;

  /

  CREATE or REPLACE TYPE table_obj AS TABLE OF ref type_obj;

  /

  CREATE or REPLACE TYPE type_obj () IS OBJECT

  fake number

  Table_obj RETURN of the FUNCTION MEMBER f

  );

  /

  Now, it must implement the body of type.

  Note that a table of the REFs is not very useful in the plain of PL/SQL, the underlying data must be stored in a nested table if you want to use.

• Function that returns null instead of the expected value

  I use SQL Developer version 3.2.20.09. When I run a certain custom stand-alone function, I get a result null instead of the numeric result. Other people in my workgroup to get the correct result. When I run the function by using SQL Plus, I get the expected result. Is it possible there are a few settings in SQL Developer that is causing this behavior?

  Any ideas appreciated.

  Yes, but without seeing your code, it is difficult to know for sure. The first thing I would check is your NLS settings in tools > Preferences.

• Go to a function that returns a Boolean

  Short version of the question: Boolean values can be returned by a pl/sql function?

  I've implemented a short function which returns a Boolean value; When I compile it I get an error:

  Error report:

  ORA-06550: line 5, column 32:

  PLS-00382: expression is of the wrong type

  ORA-06550: line 6, column 4:

  PLS-00306: wrong number or types of arguments in the call to "PUT_LINE '.

  ORA-06550: line 6, column 4:

  PL/SQL: Statement ignored

  06550 00000 - "line %s, column % s:\n%s".

  * Cause: Usually a PL/SQL compilation error.

  * Action:

  The closest, I appealed

  
  

  RETURN sys.diutil.bool_to_int (< foo >);

  
  

  and then a caller script can call

  
  

  sys.diutil .int_to_bool (< bar >);

  at least this way there is no verification of the Boolean value of 'manual '.  Is it really the only way to return / call a Boolean?

  
  

  Thank you

  EDIT

  
  

  I was aware of the fact I had not provided examples of code - and was just one question fairly open. I hope that this example will show what does not work!

  
  

  I have a function that returns a Boolean value:

  
  

  create or replace

  FUNCTION myFunc (s_in IN VARCHAR2) RETURN a Boolean value

  IS

  s_out BOOLEAN: = TRUE;

  BEGIN

  RETURN s_out;

  END FUNCTION3;

  I try and call the function in the following script:

  DECLARE

  s_in varchar2 (20): = "Hello";

  s_out boolean;

  BEGIN

  SELECT myfunction (s_in) INTO s_out FROM DUAL;

  END;

  That's when I get the error. But sorry, I was looking for too many error messages! I have worked that the one I posted above is because put_line can accept only strings and numbers not Boolean, the mistake that this function returns is:

  ORA-06550: line 5, column 32:

  PLS-00382: expression is of the wrong type

  ORA-06550: line 5, column 11:

  PLS-00382: expression is of the wrong type

  06550 00000 - "line %s, column % s:\n%s".

  * Cause: Usually a PL/SQL compilation error.

  * Action:

  However, I suppose that the comment of Frank Kulash is perhaps the reason why I see this?

  Sure.  If you are having problems, post your code (both the function and some PL/SQL that calls it).

  The BOOLEAN data type exists only in PL/SQL, not in SQL, so if the function returns a BOOLEAN value, then you can't call it in a SQL statement, even if this SQL statement is used within PL/SQL.  For this reason, a lot of guys write functions that return a NUMBER (1 or 0) or a string (' t ' or 'F') rather than return a BOOLEAN value.

• ADF Faces: RicheTableau - how to create a richeTableau method of bean datacontrol object that returns a list of objects

  Build JDEVADF_12.1.2.0.0_GENERIC_130608.2330.6668

  I have a data bean control method that returns a list of SearchResultRow objects. Each SearchResultRow has a list of SearchResultColumn objects. SearchResultColumn is the attribute name, value, type of data.

  The method returned data looks like:

  SearchResultRow {col1, a1, string}, {col2, a2, date}, {col4, 13, number}, {col4, a4, string}

  SearchResultRow {col1, b1, string}, {col2, b2, date}, {col4, 23, number}, {col4, b4, string}

  SearchResultRow {col1, c1, string}, {col2, c2, date}, {col4, 33, number}, {col4, c4, string}

  I try to display searchResult table depending on whether it

  col1 col2 col3 col4

  A1 a2 a4 13

  B1 b2 b4 23

  C1 c2 c4 33

  I drag my return value of method to the jsf page to create a link to the tree.

  < Tree IterBinding = "retrieveSearchResultsIterator" id = "SearchResultRow" >

  < nodeDefinition DefName = 'model. SearchResultRow"name ="SearchResultRow0">

  < AttrNames >

  < item Value = "resultType" / >

  < / AttrNames >

  < item Value = "name" / >

  < item Value = 'length' / >

  < item Value = "query" / >

  < item Value = 'type' / >

  < item Value = 'value' / >

  < / AttrNames >

  < / nodeDefinition >

  < / tree >

  On my jsf page, I added a table then reused the liaison of the tree.

  < af:table value = "#{bindings." SearchResultRow.collectionModel width}"= '100% '.

  var = "row" rowBandingInterval = "0" id = "t3" binding = "#{backingBeanScope.backing_Test4.t3}" partialTriggers ="": b1 ' columnStretching 'last' = > "

  My thought is in backing bean, loop through the table variable "line" which is my SearchResultRow and then loop SearchResultColumns of the line to build the RichColumn and add it to the table.

  My question is: is this feasible? How can I get hold of the var 'line' backing bean?

  Any other suggestions how to proceed?

  Thank you.

  Hello

  Welcome to Oracle and XML DB!

  After reviewing the documentation of oracle on the generation of xml data in the database, I managed to select normal tables and return a result xml exactly as I want:

  Have you also read about the SQL/XML functions?
  You don't have to create objects of type SQL to generate XML data.

  Using only XMLElement, XMLAgg, XMLAttributes, etc., you should be able to generate any kind of structure complex relational data and with total control over the names (which you don't have with the types of objects).
  Your example can be rewritten to:

  SELECT XMLElement("Parent",
           XMLAttributes(p.id as "Id")
         , XMLElement("Children",
             (
               SELECT XMLAgg(
                        XMLElement("Child",
                          XMLAttributes(
                            c.id as "Id"
                          , c.name as "Name"
                          )
                        )
                      )
               FROM child c
               WHERE c.parent_id = p.id
             )

• a function that returns the type with a table joint!

  Good day to all,
  I have a function that returns a type.
  
  so I select it as:
  Select * from table (function (param1, param2))
  
  now I want to combine this with a table so that the settings for the service we get from the join table. Is this possible? And how?
  I tried different options without success.
  
  something like:
  Select *.
  table table (function (b.column1, b.columnb) x), tablea b

  Is this possible?

  REGEXP_REPLACE ( s

• How to call a function that returns a SYS_REFCURSOR?

  Here's the situation.
  If I use ODP. NET to get a REF_CURSOR of a procedure in a package that it works without a hitch.
  
  If I use ODP .NET to run an Oracle function that returns a REF CURSOR, all sorts of things fool you.
  I use .NET 3.5 and ODP .NET version 2.112.1.2 (11 G). My Oracle database is 9.2.0.7.0
  
  There is this function returns a REF CURSOR.
  The code looks something like this.

  CREATE OR REPLACE FUNCTION SENDMEAREFCURSOR RETURN SYS_REFCURSOR IS
    X_REF genPkg.genericcursor;
  BEGIN
    OPEN X_REF for
      SELECT customer_id, name FROM CUSTOMERS;
    Return X_REF;

                  prm.ParameterName = "returncurse";
                  prm.Direction = ParameterDirection.ReturnValue;
                  cmd.Parameters.Add(prm);

  Now, I want to use the function according to me - if the underlying query of the view follows-
  

   select c.*, calculate_info(c.charge_id) as someInfo from some_charge;

  How to recover someInfo.CHARGE, someInfo.some_date, someInfo.some_val? I can put them as columns in the view?
  
  If you use only functions that return a single value in a view?
  
  Thank you

• Function that is supposed to change the label of a button

  I have a function that is supposed to change the label of a button component.

  "< mx:Button ="190"x ="266"id ="payoffType"labelPlacement = 'left' icon="@Embed (source ='... Toggle.png') "label ="-call ' width = '78' >
  < mx:click >
  <! [CDATA]
  updateLabels();
  
  []] >
  < / mx:click >
  < / mx:Button >

  public function updateLabels (): void
  {
  If (payoffType.label.slice (4, 5) is 'P')
  {
  
  payoffType.label = currencyPair.selectedLabel.slice (0, 3) + "Call";
  }
  on the other
  {
  payoffType.label = currencyPair.selectedLabel.slice (0, 3) + "Put";
  }
  }

  However once this is called it will update the datatip buttons (for example ' GBP Put ' that you see when you hover over the button) and the label of the button is set to "GBP" -

  Please please advise

  I think there can be question of width of button, do slightly increased it in & see what it shows as the label.
