PL/SQL :: Strong Type Dynamic Cursor?
Aug 21, 2012I'm currently using Oracle 11.2G and I was wondering if you can declare a dynamic cursor as a strong ref cursor type or can it only be declared as weak type ref cursor? Now, if it can only be declared as a weak type ref cursor, is there any way to avoid having to explicitly declare the type and field names being returned by the cursor? Meaning, is there anyway to avoid have to do something like this...
TYPE example_rec IS RECORD
(
col1 VARCHAR2,
col2 NUMBER,
col3 NUMBER,
etc...
)
Instead, I was wondering if I could just set the fields and their types by setting them as a TABLE OF the ref cursor? The reason I'm wondering if this is possible is because I have a lot of fields being returned in my cursor, and I was hoping on avoiding having to type each one out and its type.

Dec 6, 2012i found this difference between ref cursor and sys_refcursor.
If you specify return_type, then the REF CURSOR type and cursor variables of that type are strong; if not, they are weak. SYS_REFCURSOR and cursor variables of that type are weak.
my situation is i have to write many stored procedure for reports and also for entery pages. few enter pages use typed datasets and few does not.
which one is better in terms of performance and maintainability in above three conditions?

The reason is thatTom says...we can retrieve more than one row in implicit cursor. If that would be case, what's the difference between these two cursors?? when to use?? My understanding was implicit cursors" ---> single-row queryExplicit cursors ---> multi-row query Experts

Precompilers, 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.
