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.
I have the below cursor 1 which is working already.For my requirement i want to use bind variable like second cursor.But its telling Bind Variable "p_col_list" is NOT DECLARED.
How to use bind variable Here.
Cursor1:
DECLARE
emp_cv sys_refcursor;
iid NUMBER := 1;
i_sql varchar2(100);
p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd';
BEGIN
i_sql := 'select '''||REPLACE(p_col_list, ',', ''',''')||''' from dual '||CHR(10) ;
dbms_output.put_line(i_sql);
OPEN emp_cv FOR i_sql ;
END;
Cursor2:
DECLARE
emp_cv sys_refcursor;
iid NUMBER := 1;
i_sql varchar2(100);
p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd';
BEGIN
i_sql := 'select '''||REPLACE(:p_col_list, ',', ''',''')||''' from dual '||CHR(10) ;
dbms_output.put_line(i_sql);
OPEN emp_cv FOR i_sql using p_col_list;
END;
I am facing the same problem: SP2-0552: Bind variable "OLD" not declared. When my script create_trigger.sql is executed,there is no error but when i execute it inside a pl/sql block it get above error...In the trigger we are using if conditions
if(:new.sumthing=1)and (:old.sumthing=0)the
do this..
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 a problem when creating a dynamic statement. The problem is in the bind variable ':OLD.CUST_NAME' ,..my question is is there an escape character to treat the bind variable as a literal string?
{code}v_str2 := '''CUST_NAMES='''||'||'|| ':OLD.CUST_NAME' ;
EXECUTE IMMEDIATE 'create or replace trigger trg_' || SUBSTR (rec_cur.table_name, 1, 26) || ' before insert or update or delete on ' || rec_cur.owner || '.' || rec_cur.table_name || ' declare begin if UPDATING then FIFAPPS.ibug.log_errors('|| v_str2 ||' ); end if; end;';

The idea is to use some constant value in PL/SQL code with requirement to feed it to Oracle as value but not bind variable. Such constants used in multiple places in the code, so wants to declare it but from DB point of view it should be value. In my case Oracle will choose much better execution plan with real value for the table.
I tried to use constant, e.g:
CODEdeclare
const1 constant number := 1;

I have developed a form based on a database of books. The information displayed during run time is Sr No, Book name,Author, Copies, Description and Image(of the book)
I have written a PL/SQL code to display the image of the respective book for every new record. E.g Book1 should display image1, book2 displays image2 and so on. This should happen at runtime. The code is:
declare
gif_image varchar2(80):='c:ProjectBooks';
photo_filename varchar2(80);
begin
photo_filename := gif_image||lower(:books.sr_no)||'.gif';
[code].......
The error i get during compilation is

Is it possible to bind collection while opening a ref cursor. Find below the code that I am trying. My goal is to open cursor once using collection variable. Can it be done using DBMS_SQL ?

I have a query which is using literals

We are on oracle 10.2.0.4 on Solaris 10 and have a perf. issue with a bind variable using query. The query is in java application. I want to test its performance when the query doesn't use bind variable and instead uses the passed value as literal. How can it be done?
As example lets say the query is:
SQL> variable vn varchar2(20);
SQL> EXEC :vn :='ADAMS';
PL/SQL procedure successfully completed.
SQL> select * from emp where ename=:vn;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------
7876 ADAMS CLERK 7788 12-JAN-83 1100 20
1 row selected.
SQL> EXEC :vn :='KING';
PL/SQL procedure successfully completed.
SQL> select * from emp where ename=:vn;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------
7839 KING PRESIDENT 17-NOV-81 5000 10
1 row selected.
But the statements will be taken as similar statements by oracle (due to :vn). Now I want oracle to take it as literal and the change for this has to be done in java code in my actual scenario which has a different query (but conceptually it uses bind variable and I want it to use passed value as literal). How can it be done?
since the optimizer (during explain plan) assumes all bind variable to be of varchar type, while checking plan for SQL statement using bind variable of numeric and date type shall we convert (typecast) it as following?
variable n_sal number
variable dt_joining date
exec n_sal:= 1000
exec dt_joining := '12-dec-2005'
select first_name from emp_data where sal=to_number(n_sal) and joining=to_date(dt_joining);
Is it possible to:
-define a cursor with bind variables
-get a cursor record from these cursor
-and pass the bind variable in the OPEN clause
Did'nt succeed as shown in the example.

is there some open source or free tool which can graphical display V$ Views. Can TOAD do that in a good maner?
in UNIX there is the "sar" command, but a Java tool "ksar" for displaying the statistics in user friendly fashion.
I have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name
AS SELECT EMPLID, EMPL_NAME
FROM VEMPDATA@REMOTEDB
WHERE REGION = 'US';
I am wondering how the refersh happens or how do I specify the refresh clause.REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.
I am removing sal column from table tab_emp; i want to check whether any materialized view or view using this column by querying using data dictionary :- if i use like condition against query column of all_mviews it is throwing error sicne it is long data type. is there a way to search it without creating any function and use it in a query.
View 3 Replies View RelatedI have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication
1) create interim tables with similar structure as the materialized views
2) transfer all data from the materialized views to the interim tables
4) script out the materialized views structure and add in on prebuilt table option in the scripts
5) drop the materialized views
6) rename the interim tables with the same name as the materialized views
7) run the scripts to create the materialized views with on prebuilt table option
8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?
Whenever I try to create this trigger, it asks for values for :OLD and :NEW for some reason, and then when I attempt to put those in, it just says

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).
