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.

help how to extract the ref cursor in the table field
Hello.

I have a query similar to the following:
```
select department_id, cursor (select employee_id from employees where department_id = d.department_id)
  from departments d
```
Expecting to get several lines, I want this select this option to be in bulk sampled in a table variable nested (of another type of nested table) which is copied to an out parameter in a procedure. I have some doubts:
1 should. what I create the column in the inner nested table that will keep the result of the ref cursor? Ref cursor colunm? A sort of column Adrien?
2. If the column in the nested table inside that will keep the result of the ref cursor is another array, how can I write the result of the entire query in a single volume?

(I want to bulk collect everything in a single query, I know how to do with pl/sql do not inflate but using two nested for loops, that's what I try to avoid).

Thanks in advance.
It would be simpler:
```
declare
    type dep_emp_list_tbl_type
      is table of sys.OdciVarchar2List;
    v_dep_emp_list_tbl dep_emp_list_tbl_type;
    v_dep_id_tbl sys.OdciNumberList;
begin
    select  department_id, cast(multiset(select employee_id from hr.employees where department_id = d.department_id) as sys.OdciVarchar2List)
      bulk collect into v_dep_id_tbl,v_dep_emp_list_tbl
      from hr.departments d;
end;

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!

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.

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

I write a stored procedure that returns a REF CURSOR. However, there are times when the cursor is not open if certain conditions are not met, so I wonder if there is a way to initialize the REF CURSOR so that the appellant does not receive the "ORA-01001: Invalid cursor" error when you try to work with the cursor, if it has not been opened.

Any help is greatly appreciated...

Thank you

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.

How to create a Ref cursor table
I have a proc that returns a Ref Cursor, what is the easiest way to create a table based on the return of the ref cursor?

declare
type rc is ref cursor;
p_data rc;
Start
call_my_proc (p_data);
: result: = p_data; ((- If I run this in TOAD I can see the data here, but I want to create a table based on it rather than showing)
end;

Thank you.

Edit: sorry. typed this wrong, first time, should be right now
I recommend you read this first... {: identifier of the thread = 886365}

and then you'll have a better idea of how to make to create a table in your query.

Return of the ref cursor of procedure where the cursor is defined in the specification
Hello

Here's pseudo-code

create or replace package test
as
cursor c_emp (number cv_emp_id)
is
Select emp_name emp where emp_id = cv_emp_id;

type ref_c is ref cursor;

function get_emp_name (number p_emp_id) return ref_c;
end test;
/

create or replace the test physics package
as
ref_c function get_emp_name (number p_emp_id)
is
ret_val ref_c;
Start
Open c_emp (p_emp_id);
ret_val: = c_emp;
return ret_val;

end get_emp_name;
end test;
/

Returns me "PLS-00382: expression is of the wrong type. I tried to use a strongly typed Ref cursor based on the cursor, but nothing helped.

Clearly, I understand something... and if I can't assign as ' ret_val: = c_emp "and if there is another key way it so please let me know.

Thank you

Ralph

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.
