SQL & PL/SQL :: Local Variables Are Bind Variables
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;
BEGIN
OPEN p_refcursor FOR select * from Test_tab WHERE item=v1;
END;

Sep 2, 2011I have written a small code while going through the PL/SQL guide but I got a message for the BIND VARIABLE. I don't think I have used any bind variable in this code.

SQL & PL/SQL :: FUNCTIONS - Bind Variables?
Nov 20, 2012Create and invoke the GET_JOB function to return a job title.
a.Create and compile a function called GET_JOB to return a job title.
b.Create a VARCHAR2 host variable called b_title, allowing a length of 35 characters. Invoke the function with job ID SA_REP to return the value in the host variable, and then print the host variable to view the result.
This is my FUNCTION:
CREATE OR REPLACE
FUNCTION GET_JOB(
p_jobid IN jobs.job_id%TYPE)
RETURN VARCHAR2
[code]...
This is how I invoked the FUNCTION but WHILE DECLARING THE BIND VARIABLE IT IS GIVING ME AN ERROR!!!!!
VARIABLE b_title VARCHAR2(35)
set serveroutput on
DECLARE
P_JOBID VARCHAR2(10);
v_jobtitle VARCHAR2(200);

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).

PL/SQL :: Bind Variables And Expression Evaluation
Aug 29, 2013i have been looking at a query that uses a wrong plan. db=11.2.0.3 with user bind peeking enabled. this is a simplified version demonstrating the problem:
select egp.bsn,egp.klantnummer as "Persoonsnummer", egp.samengesteldenaam as "Samengesteldenaam", egp.geboortedatum as "Geboortedatum"from pr_eigenschappen2 egpwhere(egp.bsn = :b1 or :b2 is null)and rownum < 51 egp.bsn is varchar2(10) and has high selectivity (almost unique), and is btree-indexed. table and index have adequate statistics. when run with b1:=928818 and b2:=928818 (both bound as varchar2(10)) a full table scan+filter is used on pr_eigenschappen2. if the query is changed to select egp.bsn,egp.klantnummer as "Persoons nummer", egp.samengesteldenaam as "Samengesteldenaam", egp.geboortedatum as "Geboortedatum"from pr_eigenschappen2 egpwhere(egp.bsn = :b1 or 928818 is null)
and rownum < 51the index on bsn is used, and the query is not taking 3.9 seconds but 1 millisecond.if i would have a choice, the query would be different. i don't want to talk about the raison d'etre of the query, i would like to know why the optimizer is not using the index in the first case.
SQL & PL/SQL :: Bind Variables - Create Or Replace Procedure
Jun 12, 2012create or replace procedure my_proc(p_user in varchar2) is
l_cursor sys_refcursor;
l_query constant varchar2(1000) :=
'select a'
|| 'from ' || p_user || '.user_table'

Suppose I execute my_proc many times and for multiple values of p_user. For performance reasons, will l_query be stored in the cache as I am using bind variables or it will not since I have the concatenation with p_user value ?

SQL & PL/SQL :: Bind Variables / Developing Stored Procedures In Developer
May 16, 2010Am using Oracle 9i and developing stored procedures in SQL Developer. Have a situation where one stored procedure A is calling another B. Stored proc B builds the SQL based on parameters passed in. For one of the parameters i would like to use a bind variable in the SQL that proc B builds. The bind var is passed back to proc A as a part of the SQL string. In proc A, i then try to bind that variable to a parameter(value), however, the bind does not seeem to work.
The SQL string contained in v_SQLStatement defined as VARCHAR(4000) that is passed back to proc A looks like:
SELECT em.event_title AS event_name,
e.start_date AS start_date,
e.end_date AS end_date
FROM d_event_ml em
inner join d_event e
ON em.event_id = e.event_id
WHERE em.language_id = 46
AND e.end_date >= SYSDATE
AND e.stream_id IN ( :v_x1 )
AND e.event_id IN (SELECT event_id
FROM d_events_seas
[code]....
and o_EventList is defined as REF CURSOR. i'm experiencing is that :v_x1 stays as :v_x1 and does not change.This is my first attempt at using bind vars. URL....
Client Tools :: Providing Bind Variables As Values In Insert Statement?

BEGIN
SELECT MAX(department_id) INTO v_max FROM departments;
:max_dept_no := v_max + 20;
INSERT INTO departments VALUES (:max_dept_no,v_dept_name, NULL,NULL) ;

ORA-00020: maximum number of processes (1100) exceeded
my oracle version is 10.2.0.2.0
when i was trying to login to oracle i got :ERROR at line 1: ORA-01012: not logged on
lucky i was having another sqlplus login ..
wht i should do to bring the number of process down without increasing the process value and shuting/restaring down db.
"Usually, when this happens, I want to get connected to the instance, so that I can try to figure out which user is causing the problem. One way to do that is to use the 'ps' command to identify some of the oldest server processes, and kill the 3-5 oldest processes, and then quickly try connecting to the database. Once you're in, you can look at things like V$SESSION to try and determine which user(s) is (are) consuming so many connections, and then go from there."

Maximum Of VALUE Field Of Each Record With Different POINT-NUMBER?
Oct 21, 2011 I need to get the maximum value of the VALUE field of each record with different POINTNUMBER, then do an update on the 2nd table.
table 1
UTCTime TIMESTAMP (6)
INTEGER POINTNUMBER
FLOAT VALUE (126)
INTEGER TLQ
table 2 (idem structure)
UTCTime TIMESTAMP (6)
INTEGER POINTNUMBER
FLOAT VALUE (126)
INTEGER TLQ
Where POINTNUMBER is six thousand different values My query only returns me the maximum of a single record:
SELECT * FROM table1 WHERE value = (SELECT MAX (value) FROM table2);
And the update:
UPDATE table2 SET to a.value = (SELECT MAX (b.value) FROM table2 b);
so does on a single record.That needed to maximize each pointnumber different? I can use a cursor to do this easier?
Insertion should first make a one-time, and then updates every 1 hour
SQL & PL/SQL :: ORA-00020 Maximum Number Of Processes 150 Exceeded
Jun 9, 2013I don't know if there is a beginner forum out there for PL SQL, but I cannot find one.I just started taking an Intermediate Oracle course to learn PL SQL. Today is my first day and I just installed Oracle 11g. I was in SQL Plus, tried the edit command. I got the message "wrote file Afiedt.buf" and then it was just a flashing cursor in the line below. I could not type any commands. I just hit the X to close the program.
What could I have done to exit the program with that flashing cursor since I was unable to type anything?

Maximum Number Of Processes Per Database User
Jun 1, 2013I am using Oracle 11g R2. (11.2.0.3)
I know that in the profiles of the user I can set limit for the number of sessions per database user, using the below command:
alter profile <profile_name> limit sessions_per_user=<required_number>;
I need to set maximum number of processes for the application user so in case they opened too many number of processes on the database they do not block the automated jobs to be run.My questions:
1. set a limit on sessions_per_user is it the same as a limit on processes? 1 proccess= 1 session ? Is there any way to limit the number of processes (not sessions) for a database user?
2. I am using RAC so the number of sessions is per the whole database, while the max number of processes is by instance (not database), so even I set a limit on the number of sessions (above the limit of processes for one of the instances) one instance may face ORA-20 errors, while the max number of sessions did not hit the limit. is there any workaround for this case?

My problem, I have the query which works correctly. However as you can see there is always a sequence number in the end of variables and I am not sure the total number of cases, so I have to create a loop for the same query.
I am doing the same things on BREINV1 BREINV2 BREINV3 BREINV4... AND BRENUMINV1 BRENUMINV2... so the sequence should add a number in the end of variables...

SQL & PL/SQL :: Finding Record In Table Having Value For Maximum Number Of Columns
Nov 25, 2011if there is any inbuilt function or way to find a row in the table that is having value for maximum number of columns.
For example, the table A has 5 columns
(c1,c2,c3,c4,c5) and it has 3 records(r1,r2,r3)
and
r1 has values only for c1,c2
r2 has values only for c1,c2,c3,c4
r3 has values only for c1
so I should get the result as "r3 has values for 4 columns & it is not having value for column c5".
