How to retrieve a view definition to re-create it somewhere when its size is more than 32767 bytes?Here are some constraints :
- We are in Oracle 9.2.0.8, meaning that we cannot use the DBMS_METADATA package.
- We cannot concatenate char and long : things like
set long 100000
select 'create or replace view my_view as ' || text from dba_views where view_name = 'MY_VIEW';
are not possible.
We wrote one data load process to load GZ files into Database.during process we will change client facing view definitions to backup table so that we can work on base tables.
This view definition changes are related to FROM and WHERE clause (not columns/type). during load process, client/user may connect to current server and accessing these views. My question is what will be the reflection of changing view definition while user is accessing view?
I created a scenario-
STEP1: Created a view-
create or replace view view_01 as
select object_name from dba_objects union all
select object_name from dba_objects union all
select object_name from dba_objects union all
[code]....
View definition is replaced by new definition while select is executing on that view. select returned number of records as per view definition one.
I have a view in schema 'sales', let say the view name is view_test.
This view sales.view_test uses two base tables, one from schema 'products' and other from its own schema 'sales'.
So in sales schema the view defination is,
create or replace view view_test
as
select * from t_test, products.t_products
where t_test.id=t_products.id
The view got created, I have granted select permisson with grant option on tables t_test, products.t_products and view_test to another user 'master'.But when i query the view from master schema I get an error saying that the view does not exists, upon analysis, I found one of the base table in the view defination has no schema name mentioned (select * from t_test, products.t_products --here only t_test mentioned rather sales.t_test), I feel because the table t_test belongs to the same schmea of the view, they did not mention the schema name. If not, does it mean that we need to always specify the schema names in the view defination for the base tables.
we have a materialized view (in Oracle 11g), usually this MV we easily drop and recreate it.
But last few days, i am trying to drop a MV, but running a long time but no result and it keeps running. not dropped also.
Bcos, db performance is good since we tried to a view using script, it is fine. Problem seems only with Materialized view.
where and how to check what is the issue?
How can I determine what views have a dblink hard coded in them? I am talking about a large number of views so bringing up each view's DDL in a GUI data dictionary tool to look is not an option. I tried running the query below unfortunately "text" is a LONG and doesn't allow the use of the "like" statement.
select * from dba_views where text like '%@%' ;
I created a view for emp1 table.
SQL> select view_name , text from dba_views where VIEW_NAME='EMP1_VIEW';
VIEW_NAME TEXT
EMP1_VEW select empid , ename , qual, dept from emp1
where empid between 1000 and 1010
Now i tried to use create or replace option
SQL>create or replace view emp1_view as
*2 select * from emp1_view with read only;*
create or replace view emp1_view as
*+
ERROR at line 1:
ORA-01731: circular view definition encountered
Actually i want to make read only view (emp1_view) ; without doping ;
i have a little doubt in Materialized view. i created a materialized view and log with the following query,
create table test_mv (a number ,b number )
alter table test_mv add constraint t_pk primary key ( a );
insert into test_mv values (1,2);
[Code]...
Now i want to update the query in the MV as 'Select a from test_mv' . for that i tried with
*'ALTER MATERIALIZED VIEW product_sales_mv AS SELECT a from test_mv;'*
But it throwing error,
Error starting at line 5 in command:
alter MATERIALIZED VIEW product_sales_mv AS SELECT b from test_mv
Error report:
SQL Error: ORA-00933: SQL command not properly ended +00933. 00000 - "SQL command not properly ended"+
*Cause:+
*Action:+
i guess i am doing wrong. i want to update it without drop and recreate

I have a quite complex view that selects from approx 10 long tables (approx 4M records each) and build one "customer sentence" pre customer id. I will be always getting just one row from this view, eg. select * from my_view where party_id = XYZ. I'll NEVER EVER select the whole view.
The problem is that running a query:
select * from my_view where party_id = XYZ takes really long time, while putting the party_id = XYZ condition directly into the view executes in 0.0 seconds.
After putting a ORDERED FIRST_ROWS(1) hint into a view the execution plans seems to be the same (or very similar) for both queries. Unfortunately, I can not transfer anything but screenshot from the environmnet - therefore I paste the exec plans as screenshots only - pls follow the link: [URL]...
View DDL:
create or replace view my_view as
select /*+ ORDERED FIRST_ROWS(1) */ pt.party_id
pt.party_id as id_klienta_mdm,
pt.master_reference_no as id_klienta_ref_mdm,
[code]...
base on performance it is better to retrieve data from view or mention the table names directly?
I have a select statement in from clause one of my table is view (which is having data collected from four tables) my question is whether performance of querry will be improved if i use directly all tables( four tables of a view) instead of a view
I've tried using Select * from ALL_TABLES but this does not return me the column info for each table.
How do I get an output of all tables in a database along with column (e.g datatypes etc)?
I'm using TOAD v8.6.1.
I got the below error while executing the procedure. What the procedure doing is recreate the objects of one schema into another. After recreating some objects it throws the error.
code is...

5 V_Xml XMLTYPE;
6 V_Xml_Ind XMLTYPE;

I have the metadata of an object in one of my database table as xml. I failed to recreate the object in the other schema using metadata api. I developed a stored function to do the above job. My function doesn't throw any error as well as it doesn't create the object.
My code snippet is
CREATE OR REPLACE PROCEDURE DDI.move_table(
table_name in VARCHAR2,
from_schema in VARCHAR2,
to_schema in VARCHAR2 )
AUTHID CURRENT_USER

The schema where i create and execute my function have dba privilege also.
i missed a tablespace that includes more than 20,000 indexes for reason. there is nothing to do with it without recreate these indexes.i could find these index's ddl createment from "dbms_metadata.get_ddl" packages.
but the DDL createment like this:

I'm unable to recreate the db link (private) in another schema/database. Even its a schema object, its come without schema name while extracting from database using metadata api.
code is below (just for extracting)

recreate paramater file if you lost init.ora or spfile.ora
STEPS
SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file 'D:ORACLEORA92DATABASEINITGPT2.ORA'
How to resolve ORA-01078 with LRM-00109 error?
For resolving these error, you should need to replace init.ora or spfile if you have backup of same files. If you don't have backup then go to alert.log and copy all parameters in one file and save as "init.ora". Modify same init.ora with some parameters which need single quotation mark " ' " like background_dump_dest,controlfiles,db_name and "dispatchers ......)". Connect as sysdba in SQL*Plus and execute command "create spfile from pfile=" or startup pfile or startup.

I cannot start our Enterprise Manager services for our newly created db. I'm encountering this error:
"$ emctl start dbconsole

I am trying to apply page validations on a tabular form. The form allows users to update data in a database table. I have created some validations such as "column x must not be null" etc and on submit, the error message appears and the relevant cells are highlighted in red. All ok so far.
However, for the primary key, I am relying on the table definitions in the Oracle database to not allow duplicate row entries. When a user tries to enter a duplicate row the error message appears but the relevant row / cells are not highlighted, just the row number is given. In a table with many rows this is a bit annoying.
Is there anyway to get the cells to highlight in red for such circumstances or do I need to create the primary keys within APEX itself?

View 24 Replies View RelatedI ran into an issue in a project where a function is recreating an index-organized table by doing:Table Structure:
CREATE TABLE table_iot(
...)
ORGANIZATION INDEX
OVERFLOW ...;
Recreate Steps:
1) Populate global temporary staging table (gtt) with data
-- where gtt is staging for target index-organized table (iot)
2) Lock the target index-organized table (iot)
3) Copy old iot data to gtt
-- gtt now contains old and new data
4) Create new index-organized table (iot2) from gtt
-- iot2 now contains old and new data
[code]...
Because index-organized tables are primarily stored in a B-tree index, you can encounter fragmentation as a consequence of incremental updates. However, you can use the ALTER TABLE...MOVE statement to rebuild the index and reduce this fragmentation.The following statement rebuilds the index-organized table admin_docindex:
ALTER TABLE admin_docindex MOVE;

im working with apex 4.2.1 and when i try to define a Dynamic action on any item, if the action type is "Set Value" or execute SQL/Javascript code it should appear a text field that let me define the action taking place. However this wont do..
this is what happens:
And this is what should happen:
I know that patch 4.2.2 solves some issues regarding dynamic actions but in the bug report there's no reference to such a problem.
I would like to know if 'user creation definition' is exported in user mode export if export is done with DBA role..If it is Not, does it mean we always need to precreate the user before we import the dump created using 'user mode export'?
View 2 Replies View Relatedis there any way I can add the DBID to my rman backup name? I've already tried %F/%f as seen in the man page. but this option remains ignored.
It works for the rman backup of the control file. but no change to get this running proper for the datafiles.
can we change the existing materialized view to normal view? if yes how?
