i HAVE THE FOLLOWING CODE WRITTEN IN A *.pc FILE. I am trying to loop to fetch data from cursor. But the code exist after it fetches the first record. Let me know what is it the right way to fetch data from cursor?

How to fetch all the rows in a cursor in local variables(host variables) in PRO C . /*For x in cur is not working....*/
View 2 Replies View RelatedI am back with one more issue. I am fetching records through a cursor from database using Pro*C and inserting some records as shown below:
EXEC SQL DECLARE cur_num CURSOR FOR
SELECT STUDENT_NUMBER
FROM STUDENTS
WHERE STDID = :temp_num
ORDER BY STUDENT_NUMBER;
EXEC SQL OPEN cur_num;
EXEC SQL WHENEVER NOT FOUND DO break;
[code]....
This code works fine sometimes but ends up with this error sometimes: ORA-01002: fetch out of sequence and also do I need to do null termination once i fetch data from the database like this:
Quote:EXEC SQL FETCH cur_num INTO :std_num ;
std_num.arr[std_num.len] = '�';
std_num is declared as varchar datatype.
I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS
TYPE emp_cur_type IS REF CURSOR;
PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER);
END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value
from v$sesstat s, v$statname n
where s.statistic# = n.statistic#
and sid = 7
and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 4
opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 11 <----- 7+
opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors)
opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 53 <----- 17+
opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded
ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.

I've a Pro*C program which fills various large tables (in different schemas). I am executing the procedures which fill the tables as PThreads (since I want them to run in parallel for performance reasons). When I execute all threads sequentially (pthread_join(last_thread) before every pthread_create(next_thread)) everything works fine. But when a run the threads in parallel (as they should run), I am getting: "ORA-24550: signal received: si_signo=11si_errno=0si_code=1si_addr=0x18 Aborted"

How I can reuse a cursor, I declare a cursor for a table where code_part = 300, then I fetch all elements until end cursor, then I close the cursor, Then I declare the same cursor again for the same table where code_part = 359, but it is not successful, when I tried to fetch the cursor again the cobol program show me the last record for the first code, How I can restart the cursor or delete it or freed the cursor position?
Recently, i had to restore /usr/lib folder (because some files crashes) to a previous point. This restore point is previous to Oracle client installation. Well, now, when i try to compile my Pro*C samples:

/oracle/oracle/product/10.2.0/client_1/precomp/demo/proc

Can i fix it without re-installing Oracle client?
I am using dynamic Pl/SQL with ProC and having problems with cursor. I've to execute stored procedure dynamically and get the result of select list into the cursor. The EXECUTE command is working fine but the FETCH gets failed with error "ORA-01002: fetch out of sequence". I've read that cursor variable can not be used with dynamic SQL.
Stored Procedure:
------------------
ROCEDURE open_mod_cur (
curs IN OUT cur_type,
module_id IN varchar2)
[Code].....
create or replace PROCEDURE newprocedur(outname OUT VARCHAR2,outroll OUT NUMBER) AS
CURSOR c1 IS
select Name,Rollno,Section from emp;
BEGIN
Open c1;
fetch c1 into outname,outroll;
Here out of 3 columns in cursor is it possible to fetch only two columns using FETCH like i did above?

View 2 Replies View RelatedI am trying to give back data from a stored procedure written in C. I registered the functions as follows:create or replace procedure version(versioninfo OUT clob) as external name "version" library myLib language c with context parameters (context, versioninfo, versioninfo INDICATOR SB4); It compiles fine. The function being called look like this:
extern "C" DLLEXPORT
void version(OCIExtProcContext* context, OCILobLocator **out, sb4 *ind_out){
OCIEnv* envh;
OCISvcCtx* svch;
OCIError* errh;
OCIExtProcGetEnv (context, &envh, &svch, &errh);
std::string versioninfo = "104";
oraub8 maxChar = 10;
[code]...
If I execute the procedure with SQLDeveloper by pressing "play" it is getting executed but there is no result. If I try to execute it from an anonymous block it results in ORA-22275 instead of doing anything.
declare
res clob;
begin
-- the following doesn't work much
--dbms_lob.createtemporary(res,true);
version(res);
dbms_output.put_line(res);
end;
Actually I have to questions:
1.) Why does Oracle give me the error? In my opinion all requirements mentioned by the error description are met.
2.) Why is there no output when executing the function via SQL Developer? Is the usage of OCILobWrite wrong?
