• View object Ref Cursor

  Hello
  
  I use ADF 11 g business components.
  
  I have a function that returns a type weak ref cursor. Number of columns is not known until the function is executed. Is there a way to create a display programmatically on this Ref Cursor object?

  You can try with

  public AttributeDef addDynamicAttribute(java.lang.String attrName)
  // or
  public AttributeDef addDynamicAttributeWithType(java.lang.String attrName,
                                                  java.lang.String javaTypeName,

  The language of business for APEX is PL/SQL, so yes you can use REF CURSOR and pass objects to you packaged functions/procedures.

  How does this relate to Oracle APEX?

  Please explain what you plan to use a REF CURSOR in the APEX.

• Report regions - use of the Ref Cursor?

  APEX 4.2

  See http://mikesmithers.wordpress.com/2012/02/22/getting-apex-to-play-with-ref-cursors

  The above article is older than 2 years. The techniques shown in the link above still valid today if we want to create a report region in the APEX are based on a function that returns a Ref Cursor? Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  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.

• 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?

  Thank you!

• 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
   )
   is
   begin
            Select     t_adress(cl.t_h_no,cl.t_pin_code)
            bulk collect into p_emp_dtls
            from     r_dummy,table(emp_address) cl
            where     emp_id = p_emp_id;
   
   end;
   /
   
   set serveroutput on;
   declare
            l_emp_id          r_dummy.emp_name%type := 1;
            l_emp_dtls          t_address_tbl;
   begin
            p_using_col(l_emp_id,l_emp_dtls);
            
            for i in 1..l_emp_dtls.count
            loop
            
                 dbms_output.put_line(l_emp_dtls(i).t_h_no);
            
            
            
            
            end loop;
   
   
   end;

  Using Ref Cursor
  

  Create or replace procedure p_using_ref
   (
   p_emp_id          in     r_dummy.emp_name%type,
   p_emp_dtls          out     sys_refcursor
   )
   is
   begin
            Open p_emp_dtls for
                 Select     cl.t_h_no,cl.t_pin_code
                 from     r_dummy,table(emp_address) cl
                 where     emp_id = p_emp_id;
   
   end;
   /
   
   set serveroutput on;
   declare
            l_emp_id          r_dummy.emp_name%type := 1;
            l_emp_dtls          sys_refcursor;
            
            l_h_no               varchar2(500);
            l_pin_code          number;
            
            
   begin
            p_using_ref(l_emp_id,l_emp_dtls);
            
                 loop
                      fetch l_emp_dtls into l_h_no,l_pin_code;
                      
                      exit when l_emp_dtls%notfound;
                      dbms_output.put_line(l_h_no||'    '||l_pin_code);

  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

• Insert data from variables in the Ref Cursor

  I do not know how to return data from ref cursor variables That's what I've tried so far...
  

  CREATE OR REPLACE type num_obj as object (
    t_number number ,
    t_type varchar2(10) ,
    t_desc varchar2(40)
  ); 
  CREATE OR REPLACE type num_table as table of num_obj; 
  
  procedure get_all_data(p_p1 in varchar2, p_rc OUT SYS_REFCURSOR) is
     l_dat1 number := 2;
     l_dat2 varchar2(10);
     l_dat3 varchar2(40);
     t_num_o num_obj;
     t_num_t num_table;
  begin
    for l_indx in 1..5 loop
       l_dat1 := l_dat1 + l_indx;
       if ( mod(l_dat1,2)=0) then
         l_dat2 := 'EVEN';
       else
         l_dat2 := 'ODD';
       end if;
       l_dat3 := 'Number ' || l_dat1 || ' is ' || l_dat2 || ' number'; 
       l_num_o := num_obj (l_dat1, l_dat2, l_dat3);
       l_num_t := num_table(l_num_o);
    end loop;
    open p_rc for select * from table(l_num_t);
    close p_rc;
  end;

  At the end, to achieve this in Ref Cursor:

  t_number | t_type | t_desc
  ---------------------------------------
  3        | ODD    | Number 3 is ODD number
  5        | ODD    | Number 5 is ODD number
  8        | EVEN   | Number 8 is EVEN number
  12      | EVEN    | Number 12 is EVEN number
  17      | ODD     | Number 17 is ODD number

  Can something like that, where I did wrong?
  
  BTW. I did this with the function in pipeline, now I want to try a different method.

  The refcursor can not be closed in the procedure - you must return refcursor open to the appellant.
  the appellant must read and then close it.
  There are also some errors in the names of variables and an assignment to the collection.

  Try this version:

  CREATE OR REPLACE
  PROCEDURE GET_ALL_DATA(P_P1 IN VARCHAR2, P_RC OUT SYS_REFCURSOR) IS
     l_dat1 number := 2;
     l_dat2 varchar2(10);
     L_DAT3 VARCHAR2(40);
     L_NUM_O NUM_OBJ;
     l_num_t num_table := num_table() ;
  BEGIN
    for l_indx in 1..5 loop
       l_dat1 := l_dat1 + l_indx;
       if ( mod(l_dat1,2)=0) then
         l_dat2 := 'EVEN';
       else
         l_dat2 := 'ODD';
       end if;
       l_dat3 := 'Number ' || l_dat1 || ' is ' || l_dat2 || ' number';
       L_NUM_O := NUM_OBJ (L_DAT1, L_DAT2, L_DAT3);
       L_NUM_T.EXTEND;
       l_num_t( l_indx ) := l_num_o;
    end loop;
    OPEN P_RC FOR SELECT * FROM TABLE(L_NUM_T);
  END;
  /

• Ref Cursor is supported by their SUMMIT?

  Version 3.2 of the apex
  ORacle 10G

  Hi Ashalon,

  I don't have access to this book, so it is difficult to answer for what he says, but the PIPELINED function should return a type of collection (nested table or varray) - that would be a table of 'something '. That "something" could be a type of object defined by you (if the REF CURSOR data structure are correlated to a specific table) or simply a line-type I made for simplicity. Yes, my example is a nested table type.

  If I can make a suggestion - play with the concepts of packaging your routines back REF CURSOR in PIPELINED functions using just the SQL or SQL command window * more before trying to integrate them into an ApEx application. Less variable to deal with at the same time.

  Hope this helps,
  John

• Problem with weakly typed ref Cursor

  I have problem with a procedure in a package that returns a weakly typed reference cursor.
  The cursor that is returned to give the desired result when connected as sys and sysdba.
  But the user has rights of execution on the slider isn't a result.
  If I run the query for the cursor as a user I get the desired result
  I tried creating a new procedure outside of the package and it still doesn't work the way I want it.
  
  I tested changing authentication none in sqlnet.ora and still no results
  
  Procedure
  create or replace procedure ReportUnits (in the SYS_REFCURSOR cResult)
  AS
  Start
  
  Open the cResult for
  Select distinct c.company, c.name, c.companycode
  all_views o, fakta.balance_table b, fakta.company c
  where b.company = c.company
  and o.view_name like upper(b.company ||) '_' || b.balance_table | '_view %');
  
  end ReportUnits;
  Tried the two SYS_REFCURSOR and
  Typedef t_cursor as ref cursor;
  
  I get no error message.

  Sorry user_views does not solve the problem using all user_views I get no result points of view because interested does not belong to the user.

  So who owns the upper(b.company ||) '_' || b.balance_table | views of '_view' %)? And the package is created with copyrighted (by default) or with authid current_user? If the package is created with copyrighted, it still operates as package regardles of owner who runs it. Package owner (not the appellant) must have accsess to view granted directly, without going through role (rights define stored objects do honor no roles). And since rights define package runs as the owner of package, all_views will show views package owner has access, not package calling.

  One last thing - what happens if more than one schema has upper(b.company ||) '_' || b.balance_table | views of '_view' %)? Do you want them or only in a specific schema?

• Need the difference between strong Ref Cursor and weak Ref Cursor examples

  Oracle 9.2
  
  It would be great if someone can help understand the differences between
  1 Strong Ref Cursors(return type)
  and
  2. weak Ref Cursor (no return type)
  
  What I read is weak ref Cursor as sys_refcursor is better to use the ref Cursor, because in the case of slider strong Ref object type that will be returned must be declared in advance. It dosent make sense to me?
  
  I start with the examples would be appreciate for advice
  
  Strong Ref Cursor
  
  create the package str_pack
  is
  type sref_type is ref cursor return emp % rowtype;
  SVAR sref_type;
  end str_pack;
  
  Create procedure st_proc (eid in number, c1 on str_pack.sref_type)
  is
  Start
  Open c1 to select empno, ename, sal from emp where empno = eid;
  end;
  
  declare
  str_pack.sref_type C1;
  type rec is RECORD (eid, ename varchar2 number (20), number of sal);
  SheikYerbouti rec;
  Start
  st_proc(10,C1);
  loop
  When exit c1% notfound;
  Fetch c1 into SheikYerbouti.
  end loop;
  Close c1;
  end;
  
  
  There could be errors in the above example but its basically to get a better understanding.
  
  For weak Ref Cursor
  
  procedure of the child
  
  Create procedure child_proc (in number, c1 on sys_refcursor eid)
  is
  Start
  Open c1 to select empno, ename, sal from emp where empno = eid;
  end;
  
  parent process
  
  Create procedure parent_proc (recnum varchar2)
  is
  p_retcur sys_refcursor;
  emp_row emp % rowtype;
  Start
  child_proc (eid, p_retcur);
  loop
  extract the p_retcur in emp_row;
  dbms_output.put_line(emp_row.empno ||) e '|| emp_row. Ename | "wins". emp_row. SAL);
  end loop;
  end parent_proc;

  Hello

  the fundamental difference is to do with the compiling and linking of runtime type that occurs.

  The he should explain a lot more detail than I could ever!

• Call a procedure stored via JDBC with a REF CURSOR * input variable.

  Hello
  
  S/n of my client has provided me with a stored procedure that I need to call to get information about products prices. Something along the lines of:
  
  some_package.getPrices (products IN OUT csr_type);
  
  where csr_type represents a REF CURSOR. This cursor has a product ID column and a price column. The plan is to move the cursor with the populated product id column and have the routine decorate the slider with the prices.
  
  The setting in this plan is that it seems that it is not possible to go from JDBC REF CURSOR in . However, I'm not sure, since I can only find throw comments on various forums (e.g. http://www.orafaq.com/forum/t/35088/0/), without any reference. If I go back to the client and tell them that their idea will not work, I prefer to be able to point them to a documentation somewhere
  
  So I guess my questions are:
  
  1. it is indeed impossible to pass a REF CURSOR type as a variable input on JDBC to a stored procedure?
  
  2. is there information I can do about my client?
  
  3. am I on the right track thinking I need to go down the path of an array of objects?
  
  Thank you very much to anyone who can help
  Peter Svehla.

  Hi Peter,.

  I see it, missed that you actually want to pass in a list of products. Don't think that you can do this with the current procedure. A slider is just a pointer to a result set.
  How the result set is created and what it looks like, is determined when the cursor is opened.

  What does this procedure with the cursor? -It does not have some OPEN TO ; inside?

  Or, perhaps, you are supposed to send in an open cursor (does not much sense to me)?

• How to create control provided by PL/SQL ref-cursor

  Dear valuable experts,
  
  I'm migrating oracle forms10g for JDeveloper. Currently I need a guideline or a reference to create pages of the ADF using the PL/SQL-Refcursor rather then tables or views.
  
  I need help also how can I create using PL/SQL (package) - Refcursor datacontrol.
  
  Please help me.

  Thank you.

  Zed,

  The Fusion developer's Guide has 35.9.4 article titled "How to create a view object on a REF CURSOR" which should help you.
