Function that returns only numbers

• Function to return only numbers

  Need to create a PL/SQL function that has a phone number with formatting such as (07) 6173-8765 and then simply exit numbers and return 0761738765. Needs deformat to remove all characters and spaces which are not digital.
  
  I looked around for quite some time to find the code that will do but have had no luck.
  
  Thank you

  WITH d AS (
  SELECT '(07) 6173-8765' X FROM DUAL)
  SELECT x, RegExp_Replace (x, '[^0-9]')

• 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.

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

• 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?

  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 ;

  Yes.
  Define the return as XMLType data type:

      L_RESULT XMLTYPE;
  BEGIN

           , XMLElement("Children",
               (
                 SELECT XMLAgg(
                          XMLElement("Child",
                            XMLAttributes(
                              c.id as "Id"

                            )

             )
           )

• Create the view and by using the function that returns a type oracle

  Following is possible?

• 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();

  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();

  Better to look at a function that returns a query, or use a hose to treat your cursor returned, because the APEX at the moment can NOT handle the sliders in reports...

• Need help to write a MySQL query that returns only the peer matching records

  Because I don't know how to explain it easily, I use the table below as an example.
  
  I want to create a MySQL query that returns only the records that match counterparts where 'col1' = 'ABC '.
  
  Notice the ' ABC / GHI' record does not have a Counter-match ' GHI / ABC' record. This record must not be returned because there is no Counter-Party correspondent. With this table, the ' ABC / GHI' record should be the one returned in the query.

• 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)).

  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.

• Message box in function that returns a list deletes the created list... (Dialog box)

  Hello

  I work with a complex dialogue, its purpose is to manage a section in the PDF file.

  I use a "mclv" object in the dialog box to represent data entries in the PDF file in order to manage the result in another section.

  I created a function that creates the list based on a previous section in the PDF object, the function works perfectly well.

  But I have a small question, the function used to create the list of the dialog box object performs a check with the former front list created, as appropriate,

  and if in any case it is different from the old list, I need to warn the user that the list has changed and if there were any changes applied to the result it will be returned to zero and must be recreated.

  But when the poping that message box, all lists are deleted and nothing is displayed in the objects 'mclv.

  If I remove the message box, the lists are all very well...

  Is there anyone who have come across something like this before? If so, any solution to this problem?

  I asked my question a bit too quickly, I already found a work around

  But I still don't understand why he behaves like that tho...

  I just thought how to work around this problem.

  If anyone has encountered this problem can use this solution:

  Instead of having the message inside the function to return box, I declared a global Boolean variable to the Script object

  If the message box must be displayed, the Boolean value is set to True

  Once in the initialize event of the dialog box, if the value Boolean true I call the message box and reset the value Boolean false

• Function that returns the text of the error - type of Validation

  Small question regarding creating a function that successfully compiles a validation without a text of the error control: what value the function returns to validation successful?
  
  I tried a null value, but it doesn't seem to work.
  
  Thank you.

  Hello

  How does it work?

  What return NULL validation function is passed. If it returns a character string, then the validation failed and string is displayed as the error message for validation
