wish to do a database on dvd rental in oracle following: for the ER diagram i have indetified the entities as : branch , emp, customer,dvd, rental...
1) set the one - many relationship in the above data
2) identify the attributes for customer,dvd and rental tables and thus normalise them as well.
I'm trying to write a procedure that displays customerID, customer name, product name, and the total quantity of products the customer purchased, and the total amount the customer paid.Here's the relevant Schema tables:
CREATE TABLE Product (
Product_ID NUMBER(6) NOT NULL,
Description VARCHAR2(30),
Product_Code CHAR(4));
[code]....
Now I'm trying to wrap the above query in procedure code. I believe that I need a cursor, but I don't know what kind of cursor variable to store the result of the SELECT statement in because the query selects columns from several different tables, and I'm not sure how to terminate the FOR loop (but I think probably I can use the EXIT WHEN cursor%NOTFOUND;Here's the procedure code I have written thus far:
CREATE OR REPLACE PROCEDURE find_customer_statistics IS
DECLARE
TYPE cust_stats IS REF CURSOR; weak ref cursor declaration
SELECT sales_order.customer_id, customer.name, product.description, SUM(line_item.quantity),
SUM(line_item.subtotal)
FROM sales_order, customer, product, line_item
WHERE customer.customer_id = sales_order.customer_id
AND line_item.order_id = sales_order.order_id
[code]....

1. Customer table:

2. Cust_cokeid table:
Cokeid (pk, fk)

i have also another concern as per below xml file.
My requirement is to identify perticular node ,whose having PriorValue attribute present in <pi:the Actual_Comp_Change> tag,those record should return.
<?xml version="1.0" encoding="UTF-8"?>
<pi:Extract_Employees xmlns:pi="urn:com.workday/picof">

OUTPUT:

1000 roy Intern - Master¿s B 216000
1000 roy Intern - Master¿s 00 266000
But my requirement is to display only those employeeID ,where Actual_Comp_Change tag having PriorValue attribute.
The required OutPUT should be :
EmployeeID_ Name JobTitle_ Grade ActualComp_Change_
1100 Surana Intern - Master¿s A 500000
is there any possibility to use ExistNode() function to the above quer or is there any alternative solution.

the more customers we have for our software solution the more individual oracle objects (Tables, Packages, Functions, etc.) we have in our scheme. Right now we separate these by giving them identifying names like "X_CUSTOMER1_TABLENAME" e.g. (I know ..... )
This is not very practical when keeping our reference clean and when deploying/syncing our reference with a customer db: One customer would receive the objects of other customers on a deploy.
Is there a common solution to this problem? We were thinking about having a separate scheme for each customer. That way we would have our standard, untouched scheme with the basic functionality and the customer schemes with the individual content.
To make it a bit more concrete: We have around 100 basic tables that make the most of the content/functionality of the software. Each customer might have between 1 -5 additional tables with "custom" data that is used in conjunction with the standard objects in individual packages, functions etc. The installations will be made on our customers systems. So I have in mind to have schemes 0001, 0002, etc for each customer IN OUR REFERENCE. But we would then deploy only the scheme for that certain user when installing on their system. So for example for customer 0001 I would deploy the STANDARD and 0001 scheme

He had created an object type and wanted to populate it in a query. So far so good. But then he wanted to select some attributes from that object in the same query. Basically, he wanted to do something like this:
With his_view
As
( select object_type( attr1, attr2) theobj
From his_table
Where ...
)
Select theobj.attr1
From his_view
But somehow he was hitting ORA-00904: "THEOBJ"."ATTR1": invalid identifier over and over again.Here's a test script:
Create type mhe_type As Object( col1 Number
, col2 Varchar2(30)
)

Specify a correlation name, which is alias for the table, view, materialized view, or subquery for evaluating the query. This alias is required if the select list references any object type attributes or object type methods. link...

- "Write a SELECT statement that returns one row for each customer with four columns--the customer's first and last name, the date of the customer's most recent order, and the date of the customer's oldest order and the difference between the two dates. Sort the result set so the customers who have been ordering with the company the longest appear first. Use most recent order date as a tie-breaker for the sort."

I'm trying to create a sort of nested-query within my select of attributes . i.e.
select A.a,

where A.d = B.d

I'm using the odp.net type factory (class IOracleCustomType and the specific annotations...) to map udts to c# classes.By now I had no problems with it, because I've never used "ref" attributes within the udts.Now I need the use of "ref" attributes within udts but it seems that the odp factory cannot handle those references.
For example:_*
A Simple Type:
create or replace type bookcontent_t force as object (
id number(20)
, name varchar2(1000)
);*And a collection with references to objects of this type:*
create or replace type fms_bookcontent_ref_cln force as table of *ref* bookcontent_t;The c# class is generated by odp.net.
When I retrieve data by using odp.net I get a collection with the correct number of elements but the values are null.What can I do to solve this problem with "ref" attributes/lists? How can I get the referenced object instances?
I have data in point cloud (x,y,z,a,b,c,d (a,b,c,d are some attributes about this point)). i create a point cloud (sdo_pc - geometry), block tables (sdo_geometry - geometry). if i use a function to_geometry, result is only in multi point without attributes. it is way display this 3D data, and at the same time inquire of concerning for a attributes in concrete points?

In the documentation I can read that the "ARCH wait"-events may happen in case the database is configured with the ARCH attribute.How is it possible I get these "ARCH wait"-envents and do these wait events have any effect on the "on line" performance of the database? Is it possible that a user that saves data in the database has to wait for thest "ARCH wait"-events?
