Just want to confirm, that where Oracle stores data fetched from inline view.
I am asking, as I am making an inline view on a very large table and its getting failed with TEMP space error.
Is there a function that allows the following?
select SOME_FUNCTION('N','E','S','W') from dual;
That returns
N
E
S
W
Currently I'm just doing the following
WITH direction AS
(SELECT 'N' dir FROM DUAL
UNION
SELECT 'E' FROM DUAL
UNION
SELECT 'S' FROM DUAL
UNION
SELECT 'W' FROM DUAL)
SELECT *
FROM direction;
it is possible to have a oracle database that stores data in different languages.
I have gone through few blogs which says Oracle supports Unicode characters & UTF8 supports all languages including multi-byte.
I would like to know what are the languages supported by oracle 10G.
I am working on this assignment question for class:
Write a SELECT statement that returns a single value that represents the sum of the largest unpaid invoices for each vendor (just one for each vendor). Use an inline view that returns MAX(invoice_total) grouped by vendor_id, filtering for invoices with a balance due
What I have coded so far is below
SELECT i.vendor_id,
To_char(SUM(invoice_total), '$9,999,999.99') AS sum_invoice_total
FROM invoices i
join (SELECT vendor_id,
[code]...
I am getting some results which I have attached. I'm not sure if I'm capturing the "largest unpaid invoices for each vendor" part of the question. Yielding to the knowledge the group and trying to use the proper posting etiquette. I have attached my output screen as well.
the execution steps of inline view?importance&advantage of inline view?.Also reference link where i can get more information about inline view(i.e. basics to advanced),exercises and interview questions.

After searching a lot on net the differences between inline view and subquery that i came across are
1) you can use order by in inline view but not in subquery.
2) you can use alias for inline view but not subquery.
i have to fetch the same outcome using both the functionality respectively, then what is the technical impact/better.
I have developed a simple outbound program which creates a CSV file for all the batches uploaded in Oracle. The outbound program has a column named last_run_date
The outbound program checks for the last_update_date of batches should be greater than the last_run_date.
But the outbound program misses some rows randomly. When I run the same cursor individually, it fetches them as no other condition is violated.
I am not really able to debug the issue whether its temp table space issue or anything else.
I have written code as below. I want to insert all rows values fetched by cursor INTO table emp2 (blank as column as employees) . How Can I insert it.
what parameter or code I should used ?
I have marked with color row as below.
DECLARE
CURSOR C1 IS select * from employees;
C2 C1%ROWTYPE;

Are oracle view have Dynamic view function?
View 8 Replies View Relatedwe're having a few tables which queries about 10.000 articles. As we don't show them all at once we are using pagination and use the rownum to show only a limited number of the results.
Now as these queries are pretty complex we have to optimize them and since we use pagination we have to call our query twice (first we make a count(*) and then we call the small resultset of a few rows). Ofcourse we are looking for a solution to call it only once and still use the pagination. We could load the whole resultset of 10.000 results and let java show only a few but that makes our line between the oracle and webserver pretty heavy. Is there a way to call the total number of results and give back only a small resultset just in one query?
When to use inline query and to use join.
View 3 Replies View Relatedhow joins work with in-line views.I have a query and its explain plan as below:

I do not find any difference in both the explain plans. Both are same. In my second query, the filtered rows will be joined to dept table. And hence the baggage will reduce.But how can I verify that in-line view has worked better?
I have been using With for many queries for readability. This most recent query seemed to be taking a bit longer to run and I didn't think much of it until a colleague showed me their version (totally different sql statement) which ran faster, but seemed more complicated and had more lines of code. I noticed that the other version did not use with. I moved the sql of the with into the join and the query ran faster dropping from 30 seconds to 798 msecs. The question is am I sacrificing speed for readability by using With, or it really depends on the overall sql statement.
Here is the query using WITH:

select person_uid, id, name, academic_period,

I have created a few flash charts using APEX4.2. Is there a way for the user to view the chart and then email it as an inline image to someone?

View 3 Replies View RelatedI 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 .
