The type of OLE objects in Oracle

Hello

In Oracle, which is the equivalent to access OLE objects type?

Thank you with impatience. Concerning

I think that to store pieces image map and images, and access where typed in OLE, in Oracle, I use the BLOB data type

Yes

Question about the Type of SQL equivalent Collection Oracle

(1) I read documentation collections oracle, can I know why the 'STORE AS' clause is used only when creating the table, but not when the object creation?
Table:
```
CREATE TYPE CourseList AS TABLE OF VARCHAR2(64);
CREATE TABLE department (
  name     VARCHAR2(20),
  director VARCHAR2(20),
  office   VARCHAR2(20),
  courses  CourseList)
  NESTED TABLE courses STORE AS courses_tab;
```
Object:
```
CREATE TYPE CourseList AS TABLE OF VARCHAR2(10)  -- define type
CREATE TYPE Student AS OBJECT ( -- create object
   id_num  INTEGER(4),
   name    VARCHAR2(25),
   address VARCHAR2(35),
   status CHAR(2),
   courses CourseList)  -- declare nested table as attribute
```
(2) also can I know what is the difference between OBJECT & RECORD?
My understanding is that the OBJECT is entity sql where you create and store data in this document, while the RECORDING is PLSQL entity where you group different types of data elements in one?, hope you can give me an example to better understand.
Thank you.

Fix. The column of the course are (similar to an array) collection type. This requires a "nested table" for this column store the list of the values in this column.

This approach however is an exception to the rule - as it flies in the face of robust and sound design mathematically, relational.

(2) also can I know what is the difference between OBJECT & RECORD?

A record is similar to a struct in C/C++. A record contains one or more fields/variables. It's a basic structure for the creation of a 'container of variables' and by the way this container between code units, as oppose to pass individual variables. It is also the basis for the creation of intelligent data structures in structured programming. For example an IP socket structure is a unique smart container consisting of items/variables such as socket, protocol family and type, flags address and so on.

It is a standard feature in most (if not all) of the structured programming languages - C / C++ and Pascal, Cobol and Visual Basic. PL/SQL is based on the Ada language - and like other members of language (including Pascal), PL/SQL uses the word registration reserve to set a record structure.

Objects are created in Oracle using the "create or replace type... as object'clause. The correct term is an object oriented class. This differs from a record as a class has data and code. Unlike a record that counts only data.

Given in a class are called properties. The code of a class is called methods. There are different types of member methods and methods such as the static class constructors, destructive methods.

Oracle class object is defined using SQL. (Methods) code of this class is set using PL/SQL.

The classes also supports features like inheritance. Allowing a child class extend the implementation of the parent class. This is not supported by a record structure, beyond a structure that contains another structure as a field attribute. Classes supports the substitution in a child class, the methods of the parent class. As records are composed only of data and not code, there is nothing like ito feature for structures Records.

With the help of the TYPE operator % on objects in another schema

Suppose I have the following architecture:
* A schema called APP_SCHEMA (for example), which contains all applications level PL/SQL packages that contain a business application logic
* A data schema, called DATA_SCHEMA (for example), that contains the schema objects that are referenced by the PL/SQL in APP_SCHEMA
Suppose I create a simple procedure like this in the APP_SCHEMA:

CREATE OR REPLACE PROCEDURE test_proc(pVar IN DATA_SCHEMA.TABLENAME.TABLECOLUMN%TYPE)
AS
BEGIN
     DBMS_OUTPUT.PUT_LINE(pVar);
END;
/{code}
For this simplified procedure I get the following error:
{code:java}1/25     PLS-00201: identifier 'DATA_SCHEMA.TABLENAME' must be declared{code}So, my basic question is how do I use the %TYPE operator to reference objects in another schema?

Other Pertinent info:
* Windows Server 2003
* Oracle Database 10gR2 (10.2.0.3)
Thanks!

Its almost certainly a problem of privileges.

I can create a test procedure based on the same script that compiles successfully.

Verify that your user can access the table. Might need to have to grant access directly, rather than in a role.

How did the type of data stored in oracle timestamp

I want to know how the timestamp is stored in the oracle database.
If the data type of a colume's timestamp, the number of bytes is busy?
What is the principle?
Thank you.

Mark - it's a DATE, not a TIMESTAMP

SQL > create table test (a date, timestamp, b);

Table created.

SQL > insert into values test (sysdate, systimestamp);

1 line of creation.

SQL > select dump (a) test;

DUMP (A)

------------------------------------------------------------------------

Typ = Len 12 = 7: 120,115,1,14,17,60,3

SQL > select dump (b) of the test;

DUMP (B)

Typ = 180 Len = 11: 120,115,1,14,17,60,3,17,103,145,0

How to extract the metadata for an object in Oracle 7.3.4.3.0
Hi all

The Prod database is on Oracle 7, 7.3.4.3.0 with the 64 bit version.

I need to get the code used in the procedure, functions, packages and triggers in the database, to reproduce the problems in Oracle 10 g.

I know that dbms_metadata.get_ddl () is used to get the metadata. However, it is not available in Oracle7. Then couldn't a Tips how to get the metadata in Oracle 7.

Thank you
The code should be ALL_SOURCE or the SYS. Table of $ SOURCE.

Refer to the Oracle data dictionary views 7 server reference chapter

[CS2] [VB] How can I determine the type of object to a PageItem?

I use InDesign CS2 and VBScript
Loop to the bottom of the PageItems in a Page, I need determine the Type of object (TextFrame, group, GraphicLine... each process) and PageItem accordingly.
Is there a method/function VBS wiil returns the Type of an object as a string or a value. Or what I need to check the existence/non-existence of a particular property associated with a particular object for this type?
Alternatively, is there a JavaScript function that will do what I can call VBScript?

For the record: TypeName is what you need.

For example, when the cursor is planted in the text return TypeName (Ind.Selection (1)) 'PointInsertion.' When a text block is selected, it returns "TextFrame.

Types & confusion of object

Hi all

10.2.0.4
SLES 10

I have not yet uses types and objects eversince. And how to use it even if I read the docs, I'm confused. :(

For example, I create type with the same description as the EMP table:

create or replace 
TYPE             "EMP" AS OBJECT (
EMPLOYEE_ID                             NUMBER(6),
 FIRST_NAME                              VARCHAR2(20),
 LAST_NAME                               VARCHAR2(25),
 EMAIL                                       VARCHAR2(25),
 PHONE_NUMBER                         VARCHAR2(20),
 HIRE_DATE                                DATE,
 JOB_ID                                      VARCHAR2(10),
 SALARY                                     NUMBER(8,2),
 COMMISSION_PCT                       NUMBER(2,2),
 MANAGER_ID                              NUMBER(6),
 DEPARTMENT_ID                         NUMBER(4));

How is different from the EMP table? How to use or manipulate this?

I can also count (*), update, delete, insert and truncate her?

Thank you very much

This shows, quite simply, how object classes can be created and used as lines and tables.

Classes can also be used to add new SQL types to help you deal with complex SQL queries. For example, in {message identifier: = 10962761}, a type is used to provide a list of the values in columns in a sorted order.

Classes can also be used to define structures SQL that is returned and populated by data sources NON-SQL. For example, in {message identifier: = 10158148}, data CSV from a web interface are transformed into a SQL data and an SQL interface using object types and using a pipeline to do what it's designed to do - turn data.

Object classes also supports of the more flexible interfaces in the PL/SQL language. Instead of a caller directly using something like DBMS_PIPE, a class can be created that provides a much more flexible and intuitive interface for the caller to use.

So not - nothing to do with Java. Everything about a new set of tools in SQL and PL/SQL (not this again, like a lot of this was introduced in Oracle 8i and have since been improved on new versions).

One of the best examples of this new feature, is the type of custom object XMLTYPE SQL data - have a look at it. It's an excellent showcase for how a class should look like, what methods it should support and type of features, it must provide.

Cannot save the types of collection with the correct data type (structure type)
Hi all!

I am beginner in using the Data Modeler (SQL Develeoper Version 3.0.04 build HAND - 04.34)

I tried to define types of structured data type type collection.

for example
Types of structure: StruA (for example, Integer, Float) and StruB (e. g. whole, Timestamp, Double, Double)
Types of collections: TabA should collect the types of StruA and TabB should collect the types of StruB.

create or replace TYPE TabA IS TABLE OF StruA;
create or replace TYPE TabB IS TABLE OF StruB;

It is possible to select the correct data type in the 'Collection Type properties' dialog box.

The data type is installed to unknown after the registration and the reopening of the design. I see that the correct type has been entered in the xml file associated with the type of collection:
< dataTypeDescr class = "oracle.dbtools.crest.model.design.datatypes.CollectionType$ DataTypeWrapper" >
65677BBB-FB68-963C-552D-3F98E528520B < type > < / type >
false < isreference > < / isreference >
< / dataTypeDescr >

File name of the structured type is 65677BBB-FB68-963C-552D-3F98E528520B.xml

On the display of the design or generation DDL lose again this information.
Is - this poor handling or a bug in the Data Modeler?
Can anyone help? THX

Hey Gabor,

I'm afraid that this is a bug. This problem was reported earlier in this forum, loss of definition of type of data from one type of collection

Change the Type of the attribute at the request of the View object
Hi all

I use JDeveloper 11.1.1.6. I am trying to achieve the following problem.

My Table has a column of type VARCHAR2, but this field is to store, say, displayed in canonical format "YYYY/MM/DD hh '. I want to show the date in a nice format, as October 30, 12 ' and be able to use the datePicker adf (date. MinValue) on the attribute.

So I created an entity object, and I changed the type of the attribute of Date String.

I also created a ViewObject and the test on request module retrieves a date but seems to not understand the canonical format and date it recovers is wrong (something like 5049-02-20 12:45:30.45).

Since then, I work on EBS I oracle API access and so on, so I changed my query View object;

SELECT St St myEO.ExpiryDate-> FND_DATE.canonical_to_date (myEO.ExpiryDate) SELECT as displayed in St St. (FND_DATE.canonical_to_date would be the same thing as to_date (date, format))

When I run AppModule, NICE! It works, it retrieves the date without time and if simple format to give the attribute I can even get the format I wanted.

The problem is that when I try to update and validate changes to DB, (I replace the doDML so I can analyze my Date to a string with the format YYYY/MM/DD hh: mm: as is supposed to be) I can't even the part update. Complains in the framework;

Invalid state, another user has changed the line and blah blah blah and the problem is here:

(oracle.jbo.RowInconsistentException) Houston-25014: another user has modified the line containing oracle.jbo.Key [592674 primary key].

[178] compare entity did not attribute display
[179] original value: 2013-06-28 (that I ran with my FND_DATE.) Procedure CANONICAL_TO_DATE)
[180] target value: 5048-02-21 22:47:53.0 (I guess that the automatic distribution or conversion of the original string)
OracleSQLBuilder [181]: ROLLBACK WORK point registration "BO_SP".
[182] DCBindingContainer.reportException: oracle.jbo.RowInconsistentException

Any suggestion? I'd really appreciate it.

Edited by: Alejandro T. Lanz on 1st November 2012 06:34
Well, in short :):
When you try to update the line, frame checks the data in db and cached (from the entity object) value is different from the db value (because you Date and String objects), so that it will throw oracle.jbo.RowInconsistentException exception.

How to change the type of object?
I have an object type, as shown below:

Here are the object and its type

create or replace type test_object1 as an object
(
val1 varchar2 (50).
val2 varchar2 (50).
VARCHAR2 (50) val3

create or replace type test_type1 is table of the test_object1;

Now I want to change the type of object. I want to increase the size of val1 to varchar2 (100).

Any body could help for the alter script.

Thank you

Which won't work OPs example. Your example does not include the second type of object that depends on the first type.

You cannot change the underlying type unless you use the CASCADe or INVALIDATE option.
>
change the type of test_object1 change attribute (val1 varchar2 (100)) waterfall;
>
See the CASCADE clause in the link provided by Osame
>
CASCADE clause

Specify the CASCADE clause if you want to propagate the type change to the tables and dependent types. Oracle database abandons the statement if errors are found in the dependent types or tables, unless you also specify the FORCE.

If you change the property of the type between FINAL and NON-FINAL, you must specify this clause to convert data in the tables and dependent columns. Please refer to [NOT] FINAL.

How to use the Type of Oracle Table values in the Select statement.
Hello

I get the initial set of values in the Table of Type Records of the Oracle and want to use the list of values in the Select statement.

For example, try something like the following:

TYPE t_record () IS RENDERING
ID TABLEA.ID%type,
NO TABLEA.NO%type

);
v_record t_record;
T_table TYPE IS the v_record TABLE % TYPE;
v_table t_table;

-Code to fill the values of v_table here.

SELECT ID, NO, COLLECT in BULK IN < some other table variabes here > FROM TABLEA
WHERE ID IN (i) v_table USER.USER;

I want to know how to use the Type of Oracle Table values in the Select statement.
Something like this:
```
create or replace type t_record as  object (
id number,
no number
)
/

CREATE or replace type t_table AS TABLE OF t_record;
/

set serveroutput on
declare

  v_table t_table := t_table();
  v_t1 t_table := t_table();

begin

  v_table.extend(1);
  v_table(1).ID := 1;
  v_table(1).No := 10;

  v_table.extend(1);
  v_table(2).ID := 2;
  v_table(2).ID := 20;

  SELEC t_record (ID,NO) BULK COLLECT INTO v_t1
  from TableA
  FROM TABLEA
  WHERE ID IN (select t.ID from table(v_Table) t);

  for i in 1..v_t1.count loop
    dbms_output.put_line(v_t1(i).ID);
    dbms_output.put_line(v_t1(i).No);
  end loop;
end;

Records are PL/SQL objects. They are not the SQL objects. You can create a SQL TYPE (schema level) as a collection (variable-tables only, tables nested).

So therefore your first statement is syntactically incorrect
```
CREATE OR REPLACE TYPE TEST_VALIDATION_REC IS RECORD
(order_num VARCHAR2(30),
inventory_item_id NUMBER,
reserved_YN VARCHAR2(1),
error_flag VARCHAR2(1),
Error_message VARCHAR2(2000)
);
```
You must put in an anonymous PL/SQL block or the stored procedure
```
DECLARE

   TYPE test_validation_rec IS RECORD
   (
    order_num VARCHAR2(30),
    inventory_item_id NUMBER,
    reserved_YN VARCHAR2(1),
    error_flag VARCHAR2(1),
    error_message VARCHAR2(2000)
   );

   TYPE vald_tbl iS VARRAY(10000) OF test_validation_rec;

   lv_tbl vald_tbl;

BEGIN

   lv_tbl := vald_tbl();
