Apr 27, 2012Which of the below is considered a bind variable. In example one proc. Test the parameter p1 is directly used in the query, so this can be considered as a bind variable.
Is that true about the second proc. where p1 is assigned to a local variable v1 , or this needs hard parsing because v1 is not a bind variable ?
Create or replace procedure test(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_refcursor FOR select * from Test_tab WHERE item=p1;
END;

Create or replace procedure test1(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS
v1 varchar2(100):=p1;

END;
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.
SQL & PL/SQL :: Cursor With Bind Variable And Cursor Record

i want SomeID to be put into a variable.but i still want to be able to get a normal select query at the end so that i can see the returned value:
i tried things like:

Using Variables In A Trigger?
Oct 24, 2007consider the trigger below,
CREATE OR REPLACE TRIGGER PPMAPP.PPMCR_HH_CHR_TRG
AFTER UPDATE
ON PPMCR_STEN.PPMCR_HH_CHARACTERISTICS
[code].....
The cursor HH_ATTR_CSR returns a set of values and I'm iterating each values using a loop, but when comparing the post and pre values, I have to use the variable(HH_ATT_VAR) instead of column names.Usually we give it as (re.XXXX_YYYY) but the cloumn names has to be given in the form of a variable got from the cursor like (re.HH_ATT_VAR).In doing so, I'm getting an error as "bad bind variable" So,Is there any to view the old and the new value in the local?

PL/SQL :: Executing Procedure Using Variables
Feb 6, 2013I'm trying to execute a procedure within a Declare/Begin/End statement and using variables as input parameters in my procedure but I keep on getting an Invalid SQL Statement Error. My code is below:

END_DT VARCHAR2(30);
begin
SELECT '01-APR-2011'

The table the procedure is pulling data from doesn't have proper date/time stamps but my procedure takes the varchar dates above and turns them into dates in the procedure so the input date parameters are left as just string characters.
PL/SQL :: Variables In SELECT Statement
Feb 19, 2013I was given a SQL query to develop another query that will need to do something similar. The query I was given I believe is a stored procedure. It is PL/SQL and has a SELECT statement that looks like
SELECT :var1 AS var1
FROM t1
WHERE
:var1 = 1
In the past I have seen where variables can be used in the WHERE clause like
SELECT c1
FROM t1
WHERE
c1 = :my_column_valueand this makes sense to me.
Usually :my_column_value is declared in the DECLARE block of the PL/SQL. In the query I was given, :my_column_value is not declared in any DECLARE blocks (maybe I wasn't given the entire code??). But even if it was, that would be even more confusing because in the DECLARE block it could be assigned one value and then set to another value in the WHERE clause???
The first query doesn't make sense to me and when I run it as plain SQL I get an error like "SP2-0552: Bind variable "var1" not declared. I am guessing that such a syntax is not valid for regular SQL?
The only thing I can gather that the first query does is something along the lines of
SELECT 1 as var1
so it will output a 1 for every row. Not always that interesting of a query, but it is needed sometimes, I know. But I still don't understand this type of assignment.
So what's going on here? I'd be happy to look it up and read about it myself, but I don't know what to search for.

PL/SQL :: Select INTO Multiple Variables
Apr 23, 2013I have a SELECT INTO statement as follows:
-----

AND s2.REGION = 'ANZ'
AND s1.GCM_OPP_ID = s2.GCM_OPP_ID

The statement sums up all the products attributed to the region ANZ and stores it in a NUMBER variable called anz.
The issue is that I have multiple regions: ANZ, JP, ASEAN etc. Wat I would do is to create a statement for each and every region. Is there a way to consolidate them all into a single statement. that means something like
-----
SELECT SUM(s1.PRODUCT_QTY),SUM(s1.PRODUCT_QTY),SUM(s1.PRODUCT_QTY) INTO anz, jp, asean
FROM EXACTS_TRANSACTION_HAS_PDTS s1, EXACTS_TRANSACTIONS s2, EXACTS_PRODUCTS s3

PL/SQL Loop Types - Variables Incrementing Together

the output for this loop is:
1+1=2

4+4=8
this is what I wanted. Both variables are incrementing together. However, when I try to use a FOR loop to do the same thing:
set serveroutput on;
DECLARE
num number(1) :=1;
num2 number(1) := 1;
BEGIN
FOR i in 1..4 LOOP
[code].......
I get the result:
1+1=2
1+2=3
1+3=4
1+4=5
2+5=7
2+6=8
2+7=9
2+8=10
3+9=12
DECLARE
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: number precision too large
ORA-06512: at line 8
I understand the output means the inner loop is running its course before the outer loop is started and then continuing on to exceed its limit, but I don't understand why this is or how to make it so I get the same results as the WHILE loops.
How To Set Apache Environment Variables From Forms
Dec 27, 2012We have an application, where we invoke a URL pointing to a folder on the Application Server, so that users can download files from the same.
There is user authentication provided for the URL.
Example :
Our application ABC (example) which is built with Oracle Forms 10g, hosted on Application server (itxxx123) inovkes a module GEN9999 which on pressing a button calls a URL which is open in the Internet Explorer browser.
If the URL has been called from the Forms or the Application (ABC), then it should be allowed.
If the URL is called standalone, by Opening IE Browser and invoking the URL, this should not be allowed.
However, there have been security concerns raised during Audit, saying that users can access the URL directly from the Browser instead of the Application. Also the URL is saved the Browser history, so even if the user is no longer working in the Application Team, and has moved out of the team, then the ex-user can still access the URL and view and download files.
Is there any way to restrict access to the URL such that is only accessible when it is called from the Application, and that access is restricted when directly called from the Browser.
I have seen that environment variables in httpd.conf may be usable for the above. However, not sure how to use them from Oracle Forms.
Oracle - Create Tables Using Variables In PL/SQL?

SQL & PL/SQL :: Dynamic Where Clauses And Bind Variables?
Jun 6, 2012I have a requirement where I have to return data as per filter clauses provided on the front end, which may or may not be filled as per the users' choice.
To create a test case, I have created a query joining the emp and dept tables and I add the where clauses dynamically depending on whether the filter has been provided or not.
CREATE OR REPLACE TYPE emp_ot AS OBJECT (
empno NUMBER(4),
ename VARCHAR2(10),
[Code]....
It works very well, the 'literals' are being converted into bind variables (due to CURSOR_SHARING being set to SIMILAR) and the optimizer is able to figure out the correct execution path every time, although it is true that potentially 5 versions of this query will be sitting in the shared pool, but the DBAs are happy to live with that.
Going forward in version 12, CURSOR_SHARING=SIMILAR will be deprecated and the DBAs are not happy for us to write this sort of code anymore.
Is there a suitable way to achieve what this piece of code does?
I have tried and tested this method:
SELECT emp.empno, emp.ename, emp.job, dept.deptno, dept.dname
FROM emp, dept
WHERE emp.deptno = dept.deptno
AND emp.empno = NVL(p_empno, emp.empno)
AND emp.ename LIKE NVL(p_ename, emp.ename)||'%'
...
but the query takes far longer to execute in this manner (that is using my real tables).
