I 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.
<<outer>>
declare
v_sal1 number(7,2) := 60000;
v_comm number(7,2) : v_sal1 * 0.20;
v_message varchar2(2000) := 'eligible for commission';

Which 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;
i have some confusion with bind and host variable.

I 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).
How many maximum number of bind variables,can we use in Execute Immediate.

In The Above mentioned Code, am using bind variables, In variable no. 7 in passing character string ('05124','05125')I am not able to fetch the value,
i 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.
i want to print a message just before asking for input to a bind variable

but i want to print 'hello world' before asking value for bind variable like:

Am 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....
I executed the following PL/SQL block in SqlDeveloper :
VARIABLE max_dept_no NUMBER
DECLARE
v_dept_name VARCHAR2(30) := '&p_dept_name';
v_max NUMBER(4,0);
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) ;
END;

And it gave the error : Quote:Error report:
ORA-01400: cannot insert NULL into ("HR"."DEPARTMENTS"."DEPARTMENT_ID")

how to avoid the bind variable in view.
The query is correct but it contains bind variable Based on this query, View has to be created for report
like example select * from emp where deptno = :deptno
How to get the correct result by avoiding bind variable because view does not accept bind variable.
Identical statements from this link : Parsing in Oracle — DatabaseJournal.com d. The bind variable types of the new statement should be of same type as the identified matching statement. i am getting confuse here .. when parsing occurs some links saying about bind variable.but official document never said about bind variables.

I have the code as below:
variable oldId varchar2(5)
exec :oldId :='&1'
variable newId varchar2(5)
exec :newId :='&2'
[Code]...
Since in TAB1, ID is defined as varchar2(5), and I have defined both oldId and newId as varchar2(5) in my code, I wonder why it doesn't work.
It returned this error:
DECLARE

ERROR at line 1: ORA-01722: invalid number ORA-06512: at line xx
After supply the value for oldId(val2) and newId(val1)
SQL > @thisScript val1 val2
I use dbms_output.put_line to print the command executed, it seems it is doing
UPDATE TABLE1 SET ID = val1 WHERE ID = val2
without the single quote ('val1'), ('val2'). But if I put in single quotes, the output statement
UPDATE TABLE1 SET ID = ':newId' WHERE ID = ':oldId'
The same bind logic works in SQL prompt
SQL > variable oldId varchar2(5);
SQL > variable newId varchar2(5);
SQL > exec :oldId :='val2'
SQL > exec :newId :='val1'
SQL > UPDATE TABLE1 SET ID = :newId WHERE ID = :oldId;
1 row updated.
I am wondering what should I do then? With or without single quotes?
i am getting this error when compiling (error 49 bad bind variable) is there anything wrong in this
