Function call that returns BOOLEAN

• single function call problem

  Hello
  
  almost got a sorting site but I need help with one last game - a button which, when clicked on loads a swf in a charger via another function (basically, you press the button that triggers an animation which, once completed, then shows a loader to load a swf file)
  
  I prefer to not have separate function for each individual button calls if I can help it - is there anyway I could get the function call that loads the swf file to identify which button has been activated to set it off?
  
  It's my function call for when the button is clicked:
  
  private void sample2Clicked(event:MouseEvent):void {}
  
  printLoader.unload ();
  addChild (printIntro);
  printIntro.gotoAndPlay (1);
  printIntro.addEventListener (Event.ENTER_FRAME, sampleIntroComplete);
  
  
  }
  
  
  This is the function call that triggers the charger:
  
  
  private void sampleIntroComplete(event:Event):void {}
  
  If (printIntro.currentFrame == 50) {}
  
  removeChild (printIntro);
  addChild (pldr);
  printLoader.contentLoaderInfo.addEventListener (ProgressEvent.PROGRESS, printLoaderloading);
  printLoader.load (new URLRequest ("sample_2.swf"));
  printLoader.contentLoaderInfo.addEventListener (Event.COMPLETE, printLoaderComplete);
  printIntro.removeEventListener (Event.ENTER_FRAME, sampleIntroComplete);
  
  }
  }
  
  Ideally, I would like to set this function on each button, but don't know of a way to get the function call to recognize which button has been activated to get? At the moment it's only going to load "sample_2.swf".
  
  I need to be able to say "If 1 load swf button 1", "builds on the 2 button, load swf 2" etc etc...»
  
  can someone help me?

  And another way to actually assign a string value to the "name" of the MovieClip property:

  Btn1.x = 100;
  Btn1.y = 100;
  Btn1. Name = "btn1";

  Then the code previous, I had should operate, but by adding the name property:

  btnIndex = event.currentTarget.name.toString ().slice(-1);

  These two solutions should work for you.

• 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

  Chris

  
  

  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.

  This error indicates a problem calling put_line; It has nothing to do with what returns the function.

• Problem when calling a return function of SQL BOOLEAN in package type

  Hi all
  
  I'm having a problem when you try to call a SQL function in a package with the return BOOLEAN type
  The SQL function signature is

  Looks like it's a Limitation of the jdbc drivers. Please visit the following link:
  http://www-Camden.Rutgers.edu/help/documentation/Oracle/Java.815/a64684/typesup1.htm

  Here is an excerpt from above:
  ==========================================================
  PL/SQL BOOLEAN, RECORD and the Types of TABLES of packing

  Oracle JDBC drivers support the argument of appeal or return values of PL/SQL TABLE types (now known as indexed arrays by), REGISTRATION or BOOLEAN.

  To work around the problem, you can create wrapper procedures that manage data like types supported by JDBC. For example, to wrap a stored procedure that uses PL/SQL Boolean values, you can create a stored procedure that takes a character or a number of JDBC and passes to the original procedure as BOOLEAN or, for an output parameter, accepts a BOOLEAN of the original procedure argument and pass it as a TANK or a NUMBER to JDBC. Similarly, to wrap a stored procedure that uses PL/SQL records, you can create a stored procedure that maintains a record in its individual components (such as CHAR and NUMBER). To wrap a stored procedure that uses PL/SQL tables, you can divide the data into components or perhaps use Oracle collection types.

• 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;
  END;

  .NET code looks like this. It's after a few adjustments.

          private static OracleDataReader FireMyFunc(OracleConnection oc)
          {
              try
              {
                  OracleCommand cmd = new OracleCommand();
                  cmd.Connection = oc;
                  //cmd.CommandText = "SELECT sendmearefcursor FROM DUAL";
                  //cmd.CommandType = System.Data.CommandType.Text;
                  cmd.CommandText = "sendmearefcursor";
                  cmd.CommandType = CommandType.StoredProcedure;
                  OracleParameter prm = cmd.CreateParameter();
                  prm.OracleDbType = OracleDbType.RefCursor;
                  prm.ParameterName = "returncurse";
                  prm.Direction = ParameterDirection.ReturnValue;
                  cmd.Parameters.Add(prm);
                  cmd.ExecuteNonQuery();
                  return (OracleDataReader) prm.Value; //Throws an UnableToCast exception.
              }
              catch (System.Exception ex)
              {
                 Console.WriteLine(String.Format("FireMyFunc: {0}",ex.ToString()));
                  throw;
              }
          }

  What should I do to get the refCursor?

  Hello

  You can use the GetDataReader of the OracleRefCursor object to return the datareader object.

  OracleRefCursor rc is prm (OracleRefCursor). Value;
  return of rc. GetDataReader();

• XNET Config read to fill in when a certain arbid is received (i.e. return of function call when the msg is received)

  The API XNET-CAN allows to hardware configuration such that a call to read the framework/signal does not return until the message is received (no need to query the buffer, call to the function is as an event... function returns when a message is received) or if a time-out occurs).  I don't really want to query for data, unless I absolutely have to.  My plan is to have parallel code to wait for a specific message to receive and respond (should be very fast!) whil a different loop receives all other executives.

  A time-out of the reading function call would work pretty good, but it doesn't seem to work (see extracts attached).  The value of timeout only seems to work (no error property) is a value of 0 seconds.

  Thank you

• Make sure that wire you all the inputs and outputs of your node library function call?

  This document says "make sure that wire you all the inputs and outputs of your node library function call.

  http://digital.NI.com/public.nsf/WebSearch/7253D2F0D91F68058625752F005AB672?OpenDocument&submitted&&...

  But all the terminals on the right side of the call library node considered "outputs" referred to in the foregoing statement?

  This same document continues to show the right way to allocate memory with this illustration and in the illustration, the right "outputs" are left without junctions.

  

  Am I right in assuming that the only terminals that count as outputs, those who use the code of the DLL (modify) as output?  If it is true, then all other terminals output associated with the values entered alone so don't really account as outputs, correct?

  In the parameter call-library configuration screen there is a "Constant" check box and the help that he wrote "indicates whether the parameter is a constant."  What is this box? for me in the setup of the DLL call

  Finally, assuming that a call from the DLL that is supposed to write in these five outputs, is it legitimate to use constants like this to book a space of memory for the output values?

  

  How about if local variables associated with the output terminals are used instead?

  

  Despite the linked document, it is necessary to connect the corresponding entry for simple scalar output parameters (for example a digital). LabVIEW automatically allocate memory for them. If you do not want the entries for all the output wire anyway, there should not be no difference between a constant and a local variable; I would use a constant to avoid useless local variables.

  For settings that are only entries, there is not need to connect the outlet side. It's a bit simplistic since all parameters are entered only and get one result (other than the return value), you pass a memory address and modify the content to this address, but LabVIEW manages this dereferencing pointer for you. If you want to really get into the details, learn more about pointers in C.

  The "Constant" check box acts as the qualifier "const" on a c function parameter. It tells the compiler that the function you are calling will not change this setting. If you call a function prototype includes a const parameter, then you must mark this as a constant parameter when you configure the call library function node. Otherwise, I wouldn't worry on this subject.

• Call a procedure that returns an array of the results of dotnet

  Hi I have a function in the database (see below), I am creating a Web page and you want to call the function and get the results, how can I do this in dotnet using the ODP.net. does anyone have a code please... I called procedures in the database that return of refCursors but not tables.

  Hello

  Registration table is a PLSQL type and cannot be called from OIC (this is what ODP.NET is written in). If you change the procedure to return the table or Varray of the object instead, you could do that with the support of the UDT available in ODP 11106.21 and higher.

  There is an example in this thread that you may find useful:
  By the way the table of the UDT or Collection, as IN to the OracleDbType.InputOutput HELP

• Calling an Oracle stored procedure that returns a REF cursor

  Hi guys,.
  
  I'm calling an Oracle stored procedure that returns a REF CURSOR. Here is the piece of code that I'm working on:
  
  procedure TC307_MAIN (p_program varchar2, varchar2, varchar2, result_set OUT eng_cur p_engchgno p_project) as
  Start
  IF (p_program = 'Navybased' and p_project = 'PROTECTOR-BUILD') THEN
  result_set: = comments. Tc307_Eng_Chg_Rpt.TC307_RNZN (p_engchgno, result_set = >);
  END IF;
  end TC307_MAIN;
  
  procedure TC307_RNZN (p_engchgno varchar2, result_set IN OUT eng_cur) as
  Start
  end TC307_RNZN;
  
  PL/SQL code behind TC307_RNZN is big enough, that's why I've not stuck here. Basically, the second stored procedure executes a PLSQL statement and returns a result set. I need to return the result_set in the main proceedings based on nested else statement which I am still trying to build. I get a compilation... error can someone guide me with the correct method to call the second stored procedure and returning in the main proceedings.
  
  Thank you very much.

• Oracle query of relay and access function call does not return the list

  Thanks to aid in a previous post, I received, I created an oracle 10 g feature that returns the list after you run the sql code it contains. It works in oracle, using sql developer.
  
  I need to have the list that he returned to see the place in MS Access via a relay request. It does not work so far. The string for connection etc is ok, I'm able to use passthrough queries to run sql strings correctly. But when I try to call the function through the request of relay and access initially nothing seems to happen (IE no list) and if I try to run again, there is an "ongoing call odbc error. Current operation cancelled "." There are only three records in the table. I'm missing something, someone can he spot?
  
  The application of relay and looks like this
  
  Select * from fn_testvalues of the double
  
  Once that is running in oracle.
  
  To create the test table and 2 functions below.
  
  CREATE TABLE t_values (MyValue varchar2 (10));
  
  Table created
  INSERT INTO t_values)
  SELECT 'Merced' c1 FROM dual UNION ALL
  SELECT "Pixie" dual UNION ALL
  SELECT "452" DOUBLE);
  
  3 lines inserted
  FUNCTION to CREATE or REPLACE RETURN NUMBER IS fn_isnum(p_val VARCHAR2)
  n_val NUMBER;
  BEGIN
  n_val: = to_number (p_val);
  RETURN 1;
  EXCEPTION
  WHILE OTHERS THEN
  RETURN 0;
  END;
  /
  
  Feature created
  
  table test:
  SELECT val, isnum fn_isnum (MyValue)
  OF t_values;
  
  VAL ISNUM
  ---------- ----------
  Merced 0
  Pixie 0
  1 452
  
  Now the function that is called in the application of relay:
  
  create or replace function fn_testvalues
  sys_refcursor is back
  RC sys_refcursor;
  Start
  Open rc for
  Select t_values.*, fn_isnum (MyValue) t_values IsNum;
  Return (RC);
  
  end fn_testvalues;

  Why not?

• Selection of a function that returns a sys refcursor or alternative

  I have a query that returns a result set of three columns, namely the SSN, the PAID_YEAR and the PAID_TOTAL. This query, I can:

  1. Create a view and then question him.
  2. Create a function result set and return

  If I go the first way, that a simple request like this takes more than 20 seconds:

  SELECT PAID_YEAR,PAID_TOTAL FROM VIEW_1 WHERE SSN=12345678912882;

  I know it's because when I query a view engine first brings all the rows in the view and then filters the lines for the criteria provided.

  If I go the second way I can send only a parameter and make the engine look for only the rows that match the condition and the Recordset. But I don't know how then SELECT this result set returned. I took a look at the tables in pipeline, but do not understand how to their advantage. So my final question is if it is somehow possible to select from the result set returned by a function like this:

  SELECT * FROM FUNCTION_1(12132323232).

  If Yes, then how, if not, what would be another way?

  I know it's because when I query a view engine first brings all the rows in the view and then filters the lines for the criteria provided.

  No - you don't "know that" because it is not true. Just check out the plan of the command explain to yourself. Oracle can always use appropriate indexes so that only the needed rows are returned.

  So my final question is if it is somehow possible to select from the result set returned by a function like this:

  SELECT * FROM FUNCTION_1(12132323232).
  

  No - you can't do it like that. You must use the TABLE function to process the result of the function defined in a table:

  'SELECT * FROM TABLE(FUNCTION_1(12132323232)).

  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:
  

  -- My types
  create or replace 
  TYPE CHILD_T AS OBJECT ("@ID" VARCHAR2(20), "@NAME" VARCHAR2(20));
  
  create or replace 
  TYPE CHILDREN_T AS TABLE OF CHILD_T;
  
  create or replace 
  TYPE PARENT_T AS OBJECT ("@ID" VARCHAR2(20), CHILDREN CHILDREN_T );
  
  -- The actual select
  SELECT XMLFOREST (
              PARENT_T(d.id,
              CAST ( MULTISET (SELECT c.id, c.name
                               FROM child c
                               WHERE c.parent_id = p.id) AS CHILDREN_T )
              ) AS "Parent"
          ) 
  FROM parent p;

  That gets me this:

  <Parent ID="1">
      <CHILDREN>
          <CHILD_T ID="1" NAME="xxxxx" />
          <CHILD_T ID="2" NAME="yyyyy" />
          <CHILD_T ID="3" NAME="zzzzz" />
      </CHILDREN>
  </Parent>

  It's perfect, but how to expose this result as a Web Service like this link?

   http://localhost:8080/orawsv/MY_USER/GET_CHILDREN?wsdl

  I tried this function:

  FUNCTION GET_CHILDREN (
      PARENT_ID IN VARCHAR2
  ) RETURN CLOB
  AS
      L_RESULT CLOB;
  BEGIN
      SELECT to_clob(XMLFOREST (
              PARENT_T (p.id,
              CAST ( MULTISET (SELECT c.id, c.name
                               FROM child c
                               WHERE c.parentId = p.id) AS CHILDREN_T )
              ) AS "ParentObj"
        )) AS MY_XML INTO L_RESULT
      FROM parent p
      WHERE p.i = PARENT_ID;
  
      RETURN (L_RESULT);
  END GET_CHILDREN;

  But when I access although .NET Compact Framework, I get this: "'Element' is an invalid XmlNodeType.
  
  As you can see, I just need a simple way to transport information between a Windows CE handheld computer and our database. Use functions that return simple values.
  Do I have to return the data as xml?
  What return value I should use? Varchar2 throws a buffer error output.

  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
             )
           )
         )
  FROM parent p
  WHERE p.id = :parent_id ;
  

  It's perfect, but how to expose this result as a Web Service like this link?
  [...]
  Do I have to return the data as xml?

  Yes.
  Define the return as XMLType data type:

  FUNCTION GET_CHILDREN (
      PARENT_ID IN VARCHAR2
  )
  RETURN XMLTYPE
  AS
      L_RESULT XMLTYPE;
  BEGIN
  
    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
               )
             )
           )
    INTO L_RESULT
    FROM parent p
    WHERE p.id = PARENT_ID ;
  
    RETURN (L_RESULT);
  
  END GET_CHILDREN;
  

• 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
  where x.a = b.col
  
  Is this possible?
  
  Thanks in advance?

• Function that returns only numbers

  Is it possible to have a SQL function that returns only numbers in a varchar?
  
  Example:
  
  My PHONE_NUMBER table contains a field with a phone number in VARCHAR2, it can contain:
  
  1-888-444-5555 or (514) 444-6666 or 514-222-4444 ext: 100
  
  
  I want to have a fuction which back me:
  
  18884445555 and 5144446666...
  
  
  Thanks for the help

  Hello

  For a copy of the string s with everything except the numbers (0-9), was deleted:

  REGEXP_REPLACE ( s
                 , '[^0-9]
                 )
  

  The expression above will work in Oracle 10 and higher.
  In any version, you can use TRANSLATE to remove the numbers, then reuse TRANSLATE to remove these characters from the s.

  TRANSLATE ( s,
         , '0' || TRANSLATE ( s
                                , 'A0123456789'
                      , 'A'
                      )
         , '0'
         )
  

• Function that return the name of the current report

  Hello
  
  Anyone know if there is a function that returns the name of the current report?, similar to GET_APPLICATION_PROPERTY (CURRENT_FORM) in the forms.

  LEFM

  Hello

  You can use the builtin: SRW. GET_REPORT_NAME
  This function returns the file name of the running report

  http://www.Oracle.com/webapps/online-help/reports/10.1.2/topics/htmlhelp_rwbuild_hs/rwrefex/PLSQL/builtins/SRW/srw_get_report_name.htm

  NOTE: it is not the name of the RDF file. Is the name defined in the reporting name property.
