How To Check Cursor Stats At Run Time
Sep 24, 2011I have a stored procedure running in which there is a cursor which fetches around 1500000 records and then query another table using the fetched record values.
I cannot modify the procedure as its on production. I want to know which cursor record is currently being processed by the procedure, and how many are still remaining ? How to check the cursor stats at runtime. I want to check up to which record the cursor has been fetched and how many are still remaining. I have cursor name. Is there some dynamic view to check cursor stats at runtime ?

Apr 29, 2010i want to produce a function who return XmlType element if she checks that a parameter (that i passed to here is contained in a row in a defined table)
for example
create table sec_form(
form_code VARCHAR2(8)
, sec_code VARCHAR2(5)
) ;
insert into sec_form values ('CSA','section1');
insert into sec_form values ('CSA','section2');
insert into sec_form values ('CSA','section3');
then i got my function
create or replace function checkIfSectionEnabled (elem XmlType,name_section varchar2)
return XmlType
is v XmlType;
CURSOR myCursor IS select * from sec_form where form_code = 'CSA';
begin
open myCursor;
loop
[code]....
now i'm gonna call the function (elem XmlType,name_section varchar2) and pass here "section1" for example ; and she must return me my xmltype element if she find "section1" finds section1 present;
when i try t compile i got:
Error(18,13): PL/SQL: Statement ignored

View 5 Replies View RelatedPrecompilers, OCI & OCCI :: Pro*C - Cursor Leak With Cursor Array
Sep 7, 2007I'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.

10g - Some VARCHAR2 Fields Empty?
Jul 21, 2011Once a year in the application we have a specific query that gets used a lot. It's an UPDATE that updates a single record in a single table with a few different datatypes, but the issue is happening with one of the VARCHAR2 fields. It updates one VARCHAR2(2000) and three VARCHAR2(4000) fields at the same time.
This year, 9 of the 95 times it was used resulted in one of the VARCHAR2(4000) fields as null in the database. The users would not want this field to be null and 5 of the 9 have told us they entered something (the form they're filling out is a research proposal and leaving this field empty would be pointless because it's part of the funding request, so they're not doing it). The application isn't doing it because it's not consistent. I've checked the application and these fields can't be nulled any other way.
We just found the issue so I looked back over the past years back to 2005. Last year it didn't happen at all. In 2010 it happened a handful of times. Some years there were even more times. It's not always the same field but it's always a VARCHAR2 of at least 2000 characters.
I have a lot more information but it's all just details (let me know if you need to know more). I'm wondering if there is a bug in 10g with these types of fields. I don't believe it's malicious behavior on an individual's part but I suppose that's always possible.
how to research something like this. I tried to get access to Oracle Support and the Knowledge Base I heard they have but it doesn't look like I can do that
How To Use CASE When Set Query Empty
Mar 23, 2009I have a query that will either return one record or zero records. When it returns zero records I want to replace my attributes with a sentinel, like 'N/A'. I tried the CASE statement but couldn't get anything to work
Sample (does not work):
select
(case when exists (select product from tbl_product where productid = '123') then product else 'N/A' end) product
from tbl_product
where productid= '123';
If one record exists it should produce: 'My Widget' (or whatever)
If zero records exist it should produce: 'N/A'
