I have two tables:
Table 1:
CONTENT_ID number primary key,
URL VARCHAR2(1024) not null,
TITLE VARCHAR2(200) not null
Table 2:
CONTENT_ID number primary key,
URL VARCHAR2(1024) not null,
TITLE VARCHAR2(200) not null
Both tables are the same layout however I need to merge the data to a DB View on demand. What would the SQL look like to join like this?
What is Oracle Database on Demand (DoD)? My understanding is that, it is the lingo used for Oracle Database over cloud.
In either case i have following question on Oracle DoD
1) IS there any limitation over the concurrent users on Oracle DoD ? Or thats limited to the service/pricing on Oracle DoD?
2) IS there any limitation on transaction with respect to data volume per user ?
3) Does my application need changes while connecting to Oracle DoD ( apart from connection string, i.e. Host name and SID) ?
4) Where I can find more details on Oracle DoD?
5) Where I can find pricing details on Oracle DoD ?
6) Any other limitations with Oracle DoD?
I have problem with merging rows into view. I have created "INSTEAD OF" triggers on the view for insert/delete/update of rows. However, the merge is not working and it needs rowid to work. Is there any way how to make MERGE working here ? I must use merge, because I am changing the structure of database used for large java application. And it uses tons of merge commands,changing them to insert/update is inefficient because of development-time and of course resulting execution-time.

I read earlier forum where it says that optimizer unable to interpret the conditions like order by etc etc.Now there is one view which is getting used in the query when I did select * from vw it took more than 16 hrs to complete. (bad view).

I'm trying to write a package which will allow my users to send emails, based on templates, from our system. The email body templates are stored as text in a CLOB column in a EMAIL_TEMPLATES table, along with an email_id. Here's an example:
Quote:Dear [dearname],
I write with regard to your child, [childname] who is attending [schoolname].
Now, I'm trying to write a procedure that will take an email_id and the fields such as dearname, childname, etc., merge the data into the template and return the final body of the email.
The email body will then finally be inserted into a standard HTML email template and be sent using UTL_MAIL.
I was planning on using a series of nested REPLACE functions but I'm sure there must be a tidier way than that. Particularly as I would like the procedure to be as flexible as possible to allow me to easy adapt it to receive additional fields for different email templates in future.

I have a payment table that has the ids of cds that has being sold in the past month. From there I want to make a demand wise report. I am aware of the report wizard in the oracle forms but I dont want to use it. Here are the tables in a bit more details.
payment: id_cd, price, dateofsell
cd_details: id_cd, name, price, language.
There is a requirement to make a table data in a database (eg: HR database) available in another database (eg: EMP database), instead of accessing it using database link. In EMP database(where data needs to be cloned), data will only be queried and no write operation will be done. Data in remote database (eg: HR DATABASE) will be occassionally fully truncated and reinserted. The plan is to do a similar truncate and reinsert of data (from HR database) into EMP database monthly once using dbms scheduler job. So basically data in just one table needs to be cloned in another database.
Question: For this situation, is a regular table or Materialized view the right choice to clone the table in EMP database and why? The table in HR database (remote database) is not very big.

View 1 Replies View Relatedi have a report with a parameter that i would like to print out from an On demand Process.When there is an Ajax Call Return. i want the report to show before printing.Here is an example of the code used
DECLARE
l_customerid varchar2(200);
BEGIN
l_customerid:= wwv_flow.g_x01;
select product_id
[Code]....
We have an application that has "After Submit" and AJAX "On-Demand" processes. We need the "After Submit" to fire and complete first, set an application item (by referencing the next value in a sequence), and then fire the "On-Demand" processes. We have the sequence number set accordingly, with all of the "After Submit" processes given a lower (APEX) sequence number than the "On-Demand" processes; however, it seems the "After Submit" processes are still not firing and completing because only intermittently are the "On-Demand" processes able to access the application item's value--80% of the time this value is simply blank. Making matters more complicated is that the application item is derived from an Oracle sequence, so in my "On-Demand" processes, I cannot simply re-run some of the same logic used in one of the "After Submit" processes that sets the sequence--the sequence may only be set once, and only by this "After Submit" process; we have no choice in that regard. Is there any way possible in APEX to 100% force processes to fire AND complete, one after another, in the order in which they are listed by their (APEX) sequence? In other words, if we have this:
(APEX) Seq Name & Process Type
1 process A ("After Submit")
2 process B ("After Submit")--this sets application item :XYZ
3 process C ("On-Demand)--this uses application item :XYZ and MUST have this item value available to do any processing Can we instruct APEX to fire process A, complete it, fire process B, complete it, and only then, fire process C?
Question 1) I have read the following statement in a PL/SQL book.
Quote:To check whether an existing procedure is compiled for native execution or not, you can query the following data dictionary views:
[USER | ALL | DBA]_STORED_SETTINGS
[USER | ALL | DBA ]_PLSQL_OBJECTS
However, I when i query the view USER_PLSQL_OBJECTS I get the following error message:
Quote:ORA-00942: table or view does not exist

View 3 Replies View RelatedI have been out of work for 2+ years. Am about to start a job next week doing Oracle back end, Forms, and Reports development among other things. I was asked if I could take a look at 3 report requirements and give an estimate on how long it would take to correct errors in these reports. All I have is a user requirement document stating what the report is currently doing and what it should be doing, a partial screen print of an Oracle Form showing correct data, and a sample report page showing incorrect data.
I am finding it rather difficult to give an estimate without seeing tables, relations, code, etc. Is it me or does this seem nearly impossible?I do not have access to their system yet so cannot view the database or run select statements, run the report, etc. All I have are the documents I listed above.
DB_VERSION=10.2.0.4
OS_VERSION=Windows 2008 R2
RAM_SIZE=32 GB
We have 2 production (OLTP) database( DB1 (18GB) and DB2 (200GB) ) on a server out of which DB2 database has almost 20 Materalized Views all (REFRESH FORCE ..ON DEMAND).
I have already informed the client that this is not the OLAP database where you are going to make use of the M Views for reporting purpose. However currently the client does not have any alternative.
Breif details :-
Out of 20 M Views 3 refresh once a week and where as the rest refresh every night daily.
We are currently testing a new website for which we had to re-schedule all M Views from their Old timings to New Timings i.e. Daily Basis.
But post re-scheduling the database performance was badly degarded as the database was too slow also the number of archives increasted to 300GB which was earlier 100 GB.To resolve the issue , we had to go back to the old timings and the database is currently working fine.
Requirement :-Client is looking out for an alternative solution as he needs to once again change the M View refresh time i.e. Daily Refresh.We already have 2 Oracle Instance on the server
Questions :-
1. Can i create another database ( sayTESTDB2 ) in no archivelog mode and create a db link to reduce the load on the server ?
2. If Yes .. Then is there any relavent link /example or Metalink Note ID for the same??
3. What all parameters do i need to consider while creating a DB Link ?
3. Out of 32 GB RAM , I have given 4GB and 8GB sga_max to DB1 and DB2 Respectively . Also the cpu utilization is normally 50-%60%.
Since currently we do not have any Licence for other server .. Can i make use of the same server ( i.e. creating 3 rd Oracle Instance )?
Since the main intention of this activity is reduce the load from the DB2 onto TESTDB when the daily refresh has set once again
I have a PL/SQL procedure which gathers data from multiple places as well as calculates some data. I want to store all this in a materialized view.
So, I created an object type (I've shortened the definitions):
CREATE OR REPLACE TYPE mf_record_type AS OBJECT
(identifier VARCHAR2(6),
name VARCHAR2(100));
Then created the table type of the object:
CREATE OR REPLACE TYPE mf_table_type IS TABLE OF mf_record_type;
Then in the stored procedure defined a variable of the table type:
v_mf_record mf_table_type := mf_table_type();
Then I loop and populate the record type:
v_mf_record.EXTEND(1);
v_mf_record(x) := mf_record_type(v_rec.identifier, v_mf_detail.name);
When all that is done I try and create the materialized view:
EXECUTE IMMEDIATE ('CREATE MATERIALIZED VIEW mf_snapshot_mv AS
SELECT * FROM TABLE (CAST (v_mf_record AS mf_table_type))');
ORA-00904: "V_MF_RECORD": invalid identifier
Am I doing something wrong here? Can't I create the materialized view based on something other than a physical table?
I have a column which holds the data in the below format.
Source Data :
>SNO_SDSDQ-8192-BN>SNO_54-99-24120-8192
>SNO_SDSDQ-8192-BN>SNO_54-99-24120-8192>SNO_54-90-16489-008G
>SNO_SDPMDB-008G-11>SNO_54-90-18008-008G>SNO_54-62-08791-008G>SNO_20-81-00327
>SNO_SDPMDB-008G-12>SNO_54-90-17830-008G>SNO_54-62-08598-008G>SNO_20-81-00327
[code]..
Problem Statement :
Split the above data into individual components and create columns / aliases dynamically.If the column is present then place the data under the created column.
Example 1) :
>SNO_SDSDQ-8192-BN>SNO_54-99-24120-8192
Result
Column Name : SKUCol_54-99
Data :SNO_SDSDQ-8192-BNSNO_54-99-24120-8192
Example 2)
>SNO_SDSDAA-002G-101-J>SNO_54-90-16002-002G>SNO_54-62-05781-002G>SNO_20-81-00135-5
Column Name : SKU54-90Col_54_62Col_20_81
Data :SNO_SDSDAA-002G-101-JSNO_54-90-16002-002GSNO_54-62-05781-002GSNO_20-81-00135-5
Column Name can be derieved from the components like SNO_54-62-05781-002G
i.e. SNO_54-62-05781-002G ==> SNO_-05781-002G
"54-62" will give the Col_Name
The First Column will always have data starting with
SNO_SD%
This column is constant and will be named as SKU.
I need this data to be placed in the same record / row but under different columns as per the data set.Basically, Can the data be split into multiple parts based on delimeters and the columns are created based on the unique data in the parts that form the data in the column.
How can i load the data into a new table from view,when ever scheduler runs in the night, the data gets loaded in to a view and data coming from different tables and i should load that data every day and i dont want previous data again.The data should be loaded along with view .

View 7 Replies View RelatedI have got a simple materialized view question.
I have a view which is taking long time to get back results and this view is being used in various user queries. I noticed that the SQL of the view access some tables, data of them changes rarely. So it makes sense to retrieve that data in a materialized view and somehow re-use it.
My question is how can I use the materialized view and it's data from a query.
Here is the information about database I need to connect from my view, as the underlying table for my view is in this database
Database instance : orcl
Machine name : contentm (not sure, if this needs to be used)
so in my schema, I tried the following
CREATE DATABASE LINK product_lnk2 USING 'orcl'
select * from cont20.V_FB_PRODUCT_NM@product_lnk2
where cont20 is the schema on orcl
But it gives me this error ORA-12154: TNS:could not resolve the connect identifier specified
I'm trying to create a function that simply returns the current database name (e.g: select db_unique_name FROM v$database ) from a function but when I compile it comes up with :

I am compiling and running this as the SYSTEM user and I do think that I need to set privledges/roles, etc to allow this (since I have read that using synonyms in functions/procedures requires permissions...but I cannot seem to find anything that tells me exactly what role/priveledge I need to grant/allow to let this happen.
How can we find the size of a view or synonym or table in a database. What is the code.

How I can create a Materialized View without having any data in it.
For e.g.
I create a Materialialized View based on a View.
CREATE MATERIALIZED VIEW test_mv
REFRESH FORCE ON DEMAND
AS
SELECT * FROM test_view
In the above case the data fetched by the view test_view gets stored in the Materialized View test_mv. Suppose I want materialized view test_mv to get created with all the columns of test_view but not the data. I will refresh the materialized view test_mv later for data as and when required.
What shall I do for immidiate formation of materialized view test_mv without data.
