View doubt

this is my query for a view
SELECT ot.p_date process_date, fnc."PARTY_NAME", fnc."CNTR_CODE",
fnc."BILL_ID", fnc."BILL_NO", fnc."BILL_AMT", fnc."BILL_OUT",
fnc."DEVTN_AMT", fnc."RECEIVED_AMT"
FROM as_on_date_out_tab ot, TABLE (as_on_date_out (ot.p_date)) fnc
where ot.p_date <=trunc(sysdate)
in this as_on_date_out_tab is a valid data....i dont understand what " TABLE (as_on_date_out (ot.p_date)) fnc " means...?
Please elaborate

as_on_date_out is likely a pipelined table function. A pipelined table function can be treated like a table in a SQL statement using the TABLE() operator. So
TABLE (as_on_date_out (ot.p_date)) calls the pipelined table function as_on_date_out passing in as a parameter ot.p_date and treats the collection returned from the function as a table.

Sql View Doubt

Hi all...
I am beginner of oracle sql 10g and also trainee.. i know why v r using views but im getting confused to use views bcoz im little weak to understand in english.. i have one doubt is it possible to use views in same table? can any one tell me?
Thankz

Think of a view as a stored query. A view can be created by querying one table or from a complex query joining many tables. But the end-user just sees the result, which looks like a table of rows to them. Generally you aren't trying to hide implementation but either hide sensitive data or filter unimportant data. For instance, let's say you have an employee table that has all sorts of information about an employee. Some of that information is sensitive (like their salary, any medical information, etc.). Other information (e.g., what department they work in, who their manager is) is not sensitive. If all that information is in one table but you want to hide the salary information from everyone but the HR dept., then you could make a view that selects the non-sensitive columns from the employee table and only grant select on that view to non-HR personnel. If you wanted managers only to have access to certain data in the employee table for employees that they manage, you could make a view for that as well.

Materialized views Doubt

Hi All,
I have a question regarding materialized view.
I am adding new columns to the base table of a materialized view.As part of this I do recompiling dependent objects.Do I need to take any action on materialized views? I mean Validating or recreating?
Thanks
Hena

Assuming that you're not expecting the new column to appear in the materialized view, you shouldn't need to do anything.

Validations in XI

hi,
would you recommend to do validation in xI?
for example , check if specific field contains more/less then x charachters? date is recieved in the right format , etc ....
if yes how would you implement it?

Hi Udi,
>>>>would you recommend to do validation in xI?
That depends on your scenario and its requirements. Usually the receiving application checks the business content and if it cant handle the data an exception should be raised. In case of synchronous communictation it should be easy to inform the sender about error/success; in case of asynchronous communication acknowledgements are used for that (more difficult). Additional you can configure alert categories and rules.
Doing validations at XI is - in my point of view - doubtful because of redundance. The tasks of XI are routing, mapping, controlling (BP) messages, not doing the applications work. In case of special requirements a validation can be recommentable - of course.

Doubt in attribute view on joining the table .

Hello Team
                    Can some please help me in clearing the following doubts on joining tables .
i) Can we perform a self join in attribute view in HANA . like for ex :- joining a table to itself .
ii)Can we create an analytic view without creating an attribute view i.e creating an analytic view directly on tables .
iii)When aggregation happens in calculation view exactly what happens internally .
Please suggest me with the solution of these doubts .
Regards

Hi Prag,
As Rashmi has answered your question, i would like to add up to it few more important points.
1. Do not perform self join as it will return uncertain results. It is better to avoid self join.
You can create a copy of the same table and perform join which will be consistent.
2. In an analytic view, you will be adding table to data foundation, select the output fields.In the logical join node by default your data foundation will be present (this will contain the fields that you selected for output), you need not add any attribute view to this logical join node, leave it to default. In the semantics node select the attributes and measures. Perform validation and then activate. Your analytic view without attribute view is ready. You can check the data preview.
3. In a calculation view, the records gets grouped by all the attributes and then the measures are calculated based on this grouping by using the mentioned aggregation (sum/max/min).
Eg.
Customer ID 0Calmonth Amount (aggregation = max)
1001               01.2014     100
1001               01.2014     400
1002               01.2014     200
Output:
Customer ID 0Calmonth Amount (aggregation = max)
1001               01.2014     400
1002               01.2014     200
Hope this clarifies your doubts.
Thanks and Regards,

Doubt about Tunning View Objects

Hi !. I have the following doubt about tunning View Objects:
If I have the following configuration on a VO:
All Rows
In Batches Of: 11
As Needed
Access Mode: Scrollable
Range Size: 10
Total Records On The Table: More than 100
What would happen is that while the initial render, the view cache is fetch with 11 rows from the table and the ui table shows 10. In subsequent scroll events, more queries again will be done but not when the user scrolls back. My doubt is this one: Why, while the initial render If I put a breakpoint in this overrided method executeQueryForCollection, the execution reachs there but in subsequent scroll events (forward) the execution doesn't reach there ?. I understand thast this should happen as the required rows are not yet in the cache. I would like to know a way to test this access mode and what method is executed in every roundtrip to the DB. Thankx !.

I don't think ADF needs to execute the query again - it just needs to fetch the next set of records.
So if the cursor is already open, no need to issue another query.
You can use the HTTP Analyzer to watch network traffic
Monitoring ADF Pages Round-Trips with the HTTP Analyzer
And you can use the logging features of ADF to see the queries being executed.

Doubts related to views urgent help needed

Hi all ,
i am new to oracle technology and have a doubt related to VIEWS
i have a master table job_master and i have preapred a view of the master table as
job_master_view
The view i created as create view job_master_view as select * from job_master
Now my doubt is if i exevute a SELECT FOR UPDATE NOWAIT query on the view job_master_view then will corresponding row of the master table also be locked
I am trying to execute above query to avoid simultaneous access by multiple users
I the above approach correct ? and will the row of master table get locked ?
please let me know in case my query is not clear
Thanking in advance
Regards

My question is, how long you are going to hold lock on these table? If not, you can only use select for update with requried records using where cluase. I also suggest other application which updates this table to use same kind of statement, with NOWAIT caluse, when these applicationg trying to get a lock on these records and found already locked my other, it wont block or wait, just statement fails and can be re-tried again.
Bascially triggers are used for sort of action not for selecting data. What you can do is that develop a procedure and call it in the trigger and in the procedure you can easily use dbms_outout.put_line to display output on the sqlprompt.

Doubt in Fetching data from a View

Hi all,
I want a data from a view v_tvko.How to use a view in program for fetching data from that.
Please help.
Thanks in advance.
Nithin.

Hi Nitin,
We can't directly refer a view to get data.
We need to refer the tables using which a view has been created.
Using those tables, we can fetch the data as per our requirement.
For suppose, if you go to a view in SE11, then click on Tables tab, there you can get the reference tables.Then you need to check for the fileld in those tables for which you require the data.
Post the query directly on the table instead of view.
Hope this will help you.

Anand.

View's In Oracle - Performance Issues -some doubts

Hi,
"I have some tables with names T_SRI_MMYYYY in my database.
I created a view ,Say "Summary_View" for all the table names
with "T_SRI_%".
Now i want to select data from all the tables in the view
Summary_View.
How can i do that ? Please throw some light on the same?
Thanks and Regards
Srinivas Chebolu

I've got no idea what this has to do with the subject you
posted. But you can do this:
spool alltabs.sql
SELECT 'select * from '||table_name||';'
FROM summary_views
spool off
and then from sql*Plus just run @alltabs
If you want to do this in PL/SQL you'll have to do something
fancy with EXECUTE IMMEDIATE.

Doubt Regarding Materialized View

Hello,
I am working on Oracle 10g.
We have multiple materialized Views which we Refresh in every 15 mins. My question is that can we get data from these MV's for a particular date....??

When i am Executing a query ..which was mentioned in the earlier post...m getting a particular error.
My Query
select * from db_rational_status_reaffirm_mv as of timestamp sysdate-1
Error m Getting
ORA-01555: snapshot too old : rollback segment number 4 with name "_SYSSMU4$" too small
Any Solution ..?

Doubt on Materialized view

Hi all,
I want to create materialized view, which will refresh the materialized view whenever, there is COMMIT on base table. The following
statement is correct for this requirement.
CREATE MATERIALIZED VIEW my_MV
BUILD IMMEDIATE
REFRESH COMPLETE
ON COMMIT
AS SELECT * FROM EMP@REMOTEDB;
and my question here is , is START WITH and NEXT values are required to fullfill my requirement.
Thanks,
Pal

Hi,
If U need view to referesh to when base table is committed, then no need of start with and next.
START WITH CLAUSE --- > Specify a datetime expression for the first automatic refresh time
NEXT Clause --->
Specify a datetime expression for calculating the interval between automatic refreshes.
Both the START WITH and NEXT values must evaluate to a time in the future. If you omit the START WITH value, then the database determines the first automatic refresh time by evaluating the NEXT expression with respect to the creation time of the materialized view. If you specify a START WITH value but omit the NEXT value, then the database refreshes the materialized view only once. If you omit both the START WITH and NEXT values, or if you omit the create_mv_refresh entirely, then the database does not automatically refresh the materialized view.

-- eliminate the necessity of writing the same query more than once.
WITH Clause will add readability of code.
If the scenario is such that you need to write the same query inline multiple times, you can name it using WITH clause and then use it.
In some cases it improves the performance as well. Some times it creates global temp table for the query specified in WITH clause. It can improve performance drastically, if the query is complex.
The life time of the temp table is only till that query executes.....
