  Hello

  Better just to have a simple statement in the else block

  ELSE
  open my_ptr for
  SELECT NULL
  FROM DUAL;
  return my_ptr;
  

  So whenever the IF fails, your other work without value in the cursor.

  In fact, this slider returns a single row that contains a NULL value.
  Better add a condition that will always evaluate to false (0 = 1).

• How to start the view off of the ref cursor Oracle as input/output param

  Hello world

  We use JDev 11.1.2.3 WL 10.3.6 and Java 7.

  We are at the beginning of our transition from Oracle Forms to ADF.  We have a very large forms that uses many store procedures that have IN/OUT ref Cursor parameters and tables plsql.  I tried to find information on best practices to achieve, but only seemed to find tutorials on SEO of the Oracle ref Cursor return functions.  I hope we don't have to rewrite our code of database to work with ADF.

  This is an example of a proc currently a block on a form based on directly

  The ref cursor parameter is input/output to satisfy the way the form handles this type of paradigm.

  ADF we want I hope to reuse these procs existing (without the need to wrap/overload them) on the basis of the display objects.

  Example:

  / * my record type which houses the information I want to go back * /.

  TYPE rec_hist_vacpac_status IS RECORD)

  rec_order NUMBER (5),

  rec_rownum NUMBER (5),

  return_column SAM_VACPAC.vacpac_status%TYPE,

  rec_login_id SAM_VACPAC.ins_user%TYPE,

  status_date SAM_VACPAC.status_date%TYPE

  );

  / * Sets the ref cursor type * /.

  TYPE lcur_hist_vacpac_status IS REF CURSOR;

  / * This is a procedure that would take some info link go / return

  Return the ref cursor of this information as an in / out * /.

  PROCEDURE prc_myinfo_refcur)

  pnum_identify_seq_id in NUMBERS

  pcur_myinfo IN OUT lcur_hist_vacpac_status);

  Can anyone point me in the right direction on documentation on this?

• Initialize the Ref Cursor to avoid ORA-01001: Invalid cursor

  The most appropriate way would be the caller to handle the situation. The caller must capture the exception of INVALID_CURSOR and do what is necessary.

  Other suggestions like having a separate Pavilion or a model select all will lead the appellant to act to the particular situation, that slider is not being opened. What is the case with the exception of INVALID_CURSOR raised by oracle.

  All the need for the appellant to do is manage the exception of INVALID_CURSOR and you should be good. And also INVALID_CURSOR is not a mistake, it's an exception that has a special meaning for her. In the case you sense it takes the condition when not together to return a cursor.

• 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.

  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).

• Best approach - whether to return Collections or the Ref Cursor?

  I have the table that the column is a nested table (column address) type. Now, I want to fill the same
  in a jsp page.
  
  As his collection type I am thinking to send variable Collection to front-end. And most of java professionals
  argue that the collections are the best approach.
  
  But here, in a lot of posts, I read that collections at the front end is the worst approach and it degrades performance
  and increases the load.
  
  But java assert that even if connection fails they can always display the data as the data set is with them
  How to get a set of results COLLECTION.
  
  As ref cursor is just a pointer to the real cursor lies in the comics... they're going to make one record of the other instead and once the connection is lost... they can no longer display the data. This assertion seems
  to be reasonable!
  
  How you condemn it? and prove ref Cursor is good way?
  
  
  Here's the example scenario that I have with me.
  

  create type t_adress is object(t_h_no varchar2(500),t_pin_code number);
   /
   
   create type t_address_tbl is table of t_adress;
   /
   
   create table r_dummy (emp_name varchar2(200),emp_id number,emp_address t_address_tbl)
   nested table emp_address store as emp_address_tbl;
   
   insert into r_dummy values('raghu',1,t_address_tbl(t_adress('598',500035),t_adress('600',500036)))
   
   insert into r_dummy values('raghu nadh',2,t_address_tbl(t_adress('598',500035),t_adress('600',500036)))

  Using the Collection
  

  Create or replace procedure p_using_col
   (
   p_emp_id          in     r_dummy.emp_name%type,
   p_emp_dtls          out     t_address_tbl

  Concerning
  RUSSO

  RUSSO says:
  I would like to know what really happens behind the screen IE in PGA... when we return collections...

  A collection is a PL/SQL variable. Like all PL/SQL variables, it resides in the global area of the server process that executes PL/SQL code. This memory is part of the process the process's private memory.

  If need more memory, more memory server be malloc' ed by the process.

  As he is dedicated and private memory, no other process can reap the benefits of this memory in use. It is not 'ideal' - shared memory however benefits all the processes that are involved in sharing that allocated the memory. As is the case with the SGA

  How long my set of data will reside in the PGA? He immediately fade after returning to the calling procedure? and how it degrades performance. Help me with a good link.

  Assume that you create a collection of 10 MB. The process server malloc' ed 10 MB of server memory. The PGA has thus extended.

  When your code executes the variable usage (it is out of reach of runtime), the PL/SQL engine can theoretically free up 10 MB of memory. However, it may have allocated 4 KB memory after this assignment of 10 MB. Only 4 KB is still in use. This moment results in that the process cannot shrink its allocated memory - as this free piece of 10 MB is slapbang in the middle of the used memory space.

  PGA memory is 'expensive' because it's not shared memory is private, with only the current process. PGA in memory is not so easy to decline. Memory management is a complex issue and you who ceases to use a large part of the PGA memory almost never means that this memory suddenly become free and available for other processes to use.

  Also, you have to ask yourself why you want to copy data from disk blocks into the SGA buffer (for SQL procedures) cache, then copy these data blocks of APG in the PGA (using a collection and extraction in bulk) and then copy this PGA memory on the network to the client process (TOAD or .net or Java or whatever).

  It's a lot of moving parts - which increases the complexity, lowers the performance and scalability and ups the risk of something going wrong due to the increased complexity.

  It is much simpler and much stronger, to maintain the number of moving parts to a minimum. For example to copy data directly from cache buffers of the SGA to the customer via a ref cursor

  Clearly the point of my question is being missed.

  Or maybe the question is not been clearly asked. ;)

  I want to set the cursor in the PACKAGE SPECIFICATION, and not in the package body. The issue of the bind variable and the string is neither here nor there because I pass parameters to the cursor.

  What you ask is to use a PL/SQL cursor (defined in the specifications of the package or elsewhere) and that convert a Ref Cursor. N ° cannot be done.
  PL/SQL cursors should be used in the PL/SQL code. REF CURSOR is primary used to pass back a reference to a cursor (and all queries are cursors) to a layer of application outside of PL/SQL for example .net, java, etc.. Once you start using the ref Cursor only really, you have the choice of opening it based on a (dynamic) or a fixed query string as in the examples given. You cannot open a cursor of a PL/SQL cursor definition Ref.

  The difference is that when you do:

    CURSOR cur_mycursor IS
      SELECT ...
  

  you declare a cursor in pl/sql definition, not actually a slider itself. The cursor itself is created when you issue an OPENING or a statement FOR etc. So a Ref Cursor (reference to a slider) cannot refer to the definition of the cursor because it is only a definition, not a cursor (i.e. it has not been sent engine sql and instantiated at that time here). Instead the Ref Cursor must reference a cursor (query), itself, and that may be presented as a string or as the query itself that is issued against the sql engine and then the ref cursor points

  Thus, slider ref and PL/SQL cursors are different concepts, both designed to manage cursors in a slightly different way of programming. You cannot mix them.

• Is it possible to combine dynamic &amp; static queries in the ref cursor?

  Hi all
  
  I was wondering if it is possible to combine dynamic & static queries in the ref-cursor?
  

  CREATE OR REPLACE FUNCTION dynamic_static_kk
     RETURN sys_refcursor
  AS
     o_cursor   sys_refcursor;
  BEGIN
    open 'select 1 fom dual'
         union
         select 2 from dual;
  
     RETURN o_cursor;
  END;

  In the existing code, the two parts of the query are static, but I need to improve & replacement of part would do the trick.
  
  So, I was wondering if it is possible to keep the static part 2. Of course, do both dynamic parts seems the only possible treatment for me.

  So, I was wondering if it is possible to keep the static part 2.

  Yes, it's the only way.

  If the function returns the ref cursor is the only point of access that you have data then Yes, it probably is. If you have direct access to the underlying database objects and the function does not have something very complicated, then you are probably better off creating your own body of the function returning SQL query data source.

  Everything about the dynamics of ref Cursor now I divided in 2 layers, with a function for generating the dynamic SQL and another for bind parameters open the ref cursor. APEX apps can then reuse the functions of SQL query in function body return SQL query data sources (if you take a bit of care to keep the bind variable names vaguely APEX-point-friendly).

  Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  See this for the technical background on why APEX is not yet support ref Cursor and this for more information of the Oracle team on the possibility of future support. Obviously, he did not he in 4.1. I suspect that data REF CURSOR region sources depended on a minimum requirement of DB of the 11.1.0.6 (where was introduced support for the conversion of the REF CURSOR in the cursors DBMS_SQL). As minimum DB for APEX 5.0 version is 11.1.0.7, it would be a possible feature for 5.0, but it is not classified as one.

  Hi all

  If I open a cursor once can I collect the elements of a cursor n times as above? I see one of these procedures to print the details, but not both.

  Wonder why that I'm passing same ref cursor to a second procedure.

  It doesn't throw me an error indicating that the elements of the ref cursor is already read.

  Thank you.

  Your condition is not clear. Cursor is a pointer. He points to the result set of your query. At the time wherever you collect once, it advances the pointer to the next line and so on. I wonder if the pointer can return to the previous line once you recovered.

• How to clear the Ref Cursor runtime error

  Hello everyone,
  the code as follows

  create or replace 
  procedure Country_sel(key in varchar2)
  as
  cc Res_RelcountryLan.countrycode%type;
  len Res_Language.langname_en%type;
  lid Res_Language.langid%type;
  ab Res_Language.Abrivation%type;
  type refcursorr is ref cursor;
  cur refcursorr;
  d_stmt varchar2(100);
  begin
  d_stmt := 'select RCL.countrycode,RL.langid,RL.langname_'||key||',
  RL.Abrivation from  Res_RelCountryLan RCL inner join Res_Language RL ON RCL.LangId = RL.LangId';
  open cur for d_stmt;
  loop
  fetch cur into cc,lid,len,ab;
  if cur%found then
  dbms_output.put_line(cc||lid||len||ab);
  else
  exit;
  end if;
  end loop;
  close cur;
  commit;
  end  Country_sel;

  When I run this code im getting

  ORA-06502: PL/SQL: numeric or value error: character string buffer too small
  ORA-06512: at "RASOOL.COUNTRY_SEL", line 11
  ORA-06512: at line 6

  can you please help me get rid of this problem.
  
  
  thanking you,
  Prakash

  
  d_stmt varchar2(100); 
  

  Increase the size of d_stmt. Your an a larger string assignment

  
  d_stmt := 'select RCL.countrycode,RL.langid,RL.langname_'||key||',RL.Abrivation from  Res_RelCountryLan RCL inner join Res_Language RL ON RCL.LangId = RL.LangId'; 
  

  The size of the string above is more than 100 characters.

• Adding the ability to use a ref Cursor in future versions of Apex

  Currently, it has been established that the Apex does not play well with the ref Cursor and how to get around that. What is a characteristic that the Apex team seeks in future versions? Currently we use Oracle 11 g and 1 g with 4.0.2 Apex. Your answer is most appreciated.

  Until the APEX development team adds this feature, I'd be:

  (1) write a pipeline function that will consume the ref cursor and return your data in pipeline to the calling report

  (2) write a procedure that will be called before the call to your report, who built a collection of apex you run your report off the coast of...

  Thank you
