Create TYPE question

Hi ,
I have problems to understand the create type command !
CREATE TYPE test_type AS OBJECT
( test_id_pk number,
test_city varchar2(20),
test_state varchar2(10),
test_zip number
Is this a kind of reference or what ?
thank for any commets...

In Oracle, a TYPE is a database object and also an OBJECT in the Object-Oriented Programming sense (although there are key differences between Oracle's implementation and say Java). A TYPE has attributes (and so can be used to hold data) and it has methods (which can manipulate that data).
You can find out more by reading the online documentation (which you will find here).

UserDefined Type Question - Nested Table Attribute

I have a question about some types I'm trying to create and whether or not it's even possible .....
Here's the background ...
I have the following type i created :
create type asset_stat (
stat_current varchar2(50),
stat_change_date date,
stat_change_user varchar2(30)
All this type does is simply put a user and date/time stamp when constructed. I want to track status changes for historical tracking.
Then I want to create a nested table type of the above type as follows:
create type asset_stat_nt as table of asset_stat
Then, I have another type i've created which will have the nested table type created above as an attribute.
create type asset (
asset_name varchar2(30),
asset_type varchar2(3),
asset_stat asset_stat_nt
Now, the constructor for this asset type is defined like this: ( this is where i get lost)
constructor function asset (
asset_nm IN varchar2,
asset_type_cd in varchar2,
asset_stat_cd in varchar2 ) return self as result is
begin
self.asset_nm := asset_nm
self.asset_type := asset_type_cd ;
self.asset_stat := asset_stat_nt(asset_stat_cd);
return;
end;
I just created a table of asset type and tried to do an insert and I'm getting an error related to the line where the nested type is being assigned. Is this possible? If so is my syntax completely off? I'm not quite sure how to set values for the nested type because i want to keep all records of change. Any help would be greatly appreciated.
thanks

the block of code shows that asset_stat_nt is the type assigned to asset_stat inside the type asset as shown below
create type asset (
asset_name varchar2(30),
asset_type varchar2(3),
asset_stat asset_stat_nt
I guess for the following block of code, the line with the arrows should be given like shown below in bold letters
constructor function asset (
asset_nm IN varchar2,
asset_type_cd in varchar2,
asset_stat_cd in varchar2 ) return self as result is
begin
self.asset_nm := asset_nm
self.asset_type := asset_type_cd ;
self.asset_stat := asset_stat_nt(asset_stat_cd);return;
end;
[b][b]self.asset_stat := asset(asset_stat_nt(asset_stat_cd));
I am not pretty sure.......try it anyway.....if it works....good to you

OLM || Issue with Image-type questions

Hi
This is with reference to an issue regarding the import of " Image-map " types questions in OLM.
The legacy system which the client uses allows creation and assignment of 'Image-map" types questions to the learners.
As far as my limited understanding goes, these types of questions are not supported in OLM.
How to handle such types of questions in OLM , any pointers ??
Also , what exactly are QTI standards and how to convert the existing question banks to QTI standards and then import them to OLM ??
Thanks in advance for your time..
Cheers

There is one method to support these types of questions by using HTML code in the question text, but it is definitely a workaround.
1. Use an HTML editor like Dreamweaver to create the image map or other type of interactive question. Save the html and any related images, javascript etc and upload to a content server. If the user gets the interactive question correct, provide them with some code to enter that will be used later.
2. Select a question type like fill in the blank
3. In the question text, use an IFRAME to embed the HTML page that contains the interactive question
4. The correct response for this question will be based on the "code" you provide users in the interactive question if they get it correct. They would then enter this code in the fill in the blank area and get credit for answering correctly.
Other options include building the assessment using a content authoring tool and offering the assessment as a SCORM or AICC learning object, or integrating with a third party assessment tool such as Questionmark.
Also,
Metalink Note ID #295865.1 contains the import/export API tech specification (this was originally written for Oracle iLearning but applies to OLM for the most part as well) and has info on the QTI spec that OLM and iLearning support.

How to resolve create type error?

Hi all,
I am duplicating the contents of schema1 to schema2 on the same database.
So I used expdp schema1/schema1 .... exporting schema1. Then impdp schema2/schema2 remap_schema=schema1:schema2
These 2 schemas have dba privilege.
Why do I get this error:
ORA-39083: Object type TYPE failed to create with error:
ORA-02304: invalid object identifier literal
Failing sql is:
CREATE TYPE "C1DEVADM"."CMQTNQHT" OID 'AC82C504E18C6A98E044001A4B08907C' AS TABLE OF CMQTNQHF;Thanks a lot,

Hi;
I already done exporting the data :(
I guess it will be ok if I create the object types manually after impdp right?Yes.
PS:Please dont forget to change thread status to answered if it possible when u belive your thread has been answered, it pretend to lose time of other forums user while they are searching open question which is not answered,thanks for understanding
Regard

Help Creating Types

Hello,
Hopefully I can explain this clearly.
I am using data pump import to bring several source databases into different schemas in one new database. The source databases are extracts at different times from a seperate production database and I am encountering errors as follows -
ORA-39083: Object type TYPE failed to create with error:
ORA-02304: invalid object identifier literal
Failing sql is:
CREATE TYPE "F10BANINST1"."DATE_NT" OID 'DEEC3F961E7C4CB1E0340003BA29B58F' as
table of DATE;
This makes sense as the types existed under one schema in the original database and the OIDs are present as they were imported into the first schema I created. What I need to do is create these types in each of the schemas I have created in the new database. I am not sure how best to do this. Apparently I am not able to do something like the following -
SQL> copy type schema2.TYPE from schema1.TYPE;
What I would like to do is pull the DDL from the source database into a create statement of the form -
SQL> create type schema2.type as.....
and I am not sure how to do this. I need to be certain I get the type body as well. Can someone help me do this please.
Thank you.
Bill Wagman

The OID of the object/collection type must be unique across all schemas. So trying to re-create the type in multiple schemas with the same OID will not work. You will need to choose a new OID for each schema's version of the type.
However, the obvious question is: why not create a single instance of the type, and grant privileges (EXECUTE and UNDER) to use/extend it to the other schemas?

Create type not working

I'm following the 8.1.6 documentation to create type, but it always returns me the error.
My references are from :
http://technet.oracle.com/docs/products/oracle8i/doc_library/817_doc/appdev.817/a76976/adobjmng.htm
The script is:
CREATE TYPE location (
building_no NUMBER,
city VARCHAR2(40) );
The error is:
1/15 PLS-00103: Encountered the symbol "(" when expecting one of the following:
; is authid as compress compiled wrapped
4/0 PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following:
pragma
May I know that how can I work around it?
I had tried earlier another syntex successfully:
create type typeName as object(definition....).
May I also know what's the difference between these 2 commands?
Thanks in advance
Minny

I think there's a mistake in the documentation. I may be wrong but I think it should always be CREATE TYPE x AS OBJECT (...)

Creating Types and Internal table

Hi,
I created
Types: begin of itab,
           field 1 ...
            Field 30,
        End of itab.
Data: lt_itab type table of itab.
I need to create a second type itab1 with all the itab fields and also new fields field31 and field32.
I dont want to declare all the 30 fields again for the second one.
Can any one tell me how to create this?
Thanks.
rajesh

You can INCLUDE TYPE.
Types: begin of itab,
       field1 type string,
       field2 type string,
*      More Fields in here.
       Field30 type string,
       End of itab.
Data: lt_itab type table of itab.
TYPES BEGIN OF new_itab.
       INCLUDE type itab.
TYPES: field31 type string,
       field32 type string,
END OF new_itab.

Create TYPE

I am not able to create type objects tried with different versions of oracle too.
Currently I am using Oracle 11g Enterprise edition (2.9GB).
The problem is when i create a TYPE object and when i terminate the command with a semicolon ';',oracle sql does not stop only (the query does not execute) the loop goes on and on.
I did like this and found that the SYNTAX is also perfect.
SQL> CREATE TYPE address_type AS OBJECT
2 (street varchar2(30),
3 city varchar2(30),
4 pincode number(10));

It goes on and on it never ends. Command never executes.
Please Help!

end the command with "/" :

A type body will contain PL/SQL semicolons, so once SQL*Plus sees that you're entering a type it stops treating semicolons as the SQL*Plus multi-line statement terminator character. (A type header will not contain semicolons, but I expect Oracle decided it would be even more confusing if CREATE TYPE BODY behaved differently to CREATE TYPE.)
Note you can also terminate entry by entering a dot (period) on a line on its own.
I guess in older version there was nothing like that.Actually this has been around for over 10 years ;)

Create Type as Object not working in linux oracle 11g

Pleae refer to the following simple create type as object statement.
CREATE OR REPLACE TYPE EC_VIEWABLETYPES as object ( CASE_TYPE_ID NUMBER)
It is working in oracle 11g and windows server 2008 environment.
But it is not working in oracle 11g with linux environment.
I am executing this statement as dynamic sql as follows
CREATE OR REPLACE PROCEDURE TEMP_SP
AS
BEGIN
DECLARE vcType VARCHAR2(30);
BEGIN
SELECT OBJECT_TYPE into vcType FROM USER_OBJECTS
WHERE OBJECT_NAME='EC_VIEWABLETYPES' AND OBJECT_TYPE='TYPE';
EXCEPTION
WHEN NO_DATA_FOUND THEN
EXECUTE IMMEDIATE 'CREATE OR REPLACE TYPE EC_VIEWABLETYPES as object ( CASE_TYPE_ID NUMBER) ';
COMMIT;
RETURN;
END;
END;
exec TEMP_SP
please let me know what i am missing ?

And error is:ORA-00600: internal error code, arguments: [kothc_uc_md5:lxerr], [], [], [], [], [], [], [], [], [], [], []

Error On Creating Type

I think you cannot create types if the attributes' datatypes are based on package records, constants, etc
See:
mmara@pyn> create or replace package val
is
type dummy is record (
pid number,
pname varchar2(15));
end val;
Package created.
mmara@pyn> create or replace type WS_REQUEST as object
xml xmltype,
http_request val.dummy
Warning: Type created with compilation errors.

Errors for TYPE WS_REQUEST:
LINE/COL ERROR
0/0 PL/SQL: Compilation unit analysis terminated
4/18 PLS-00201: identifier 'VAL.DUMMY' must be declared
mmara@pyn>
In that case, why don't you create the same type as seen in utl_http as an object in the schema?:
TYPE req IS RECORD (
url VARCHAR2(32767 byte), -- Requested URL
method VARCHAR2(64), -- Requested method
http_version VARCHAR2(64), -- Requested HTTP version
private_hndl PLS_INTEGER -- For internal use only
);

How do I create quiz question in reflow?

How do I create quiz question in reflow? There is form element but how am I going to get the value of the radio button or the text entry?

You can design the quiz in Reflow but you'll need to code up some sever side code to collect the data and reports for your quiz. If you don't want to write the code you could look at Muse or an online service like typeform or some elearning solution.
Hope that helps,

SQL 3 : Create type

hello,
in an example using the object-relational model
I created the following type:
create type professeur_t as object (
+     nump varchar2(5),+
+     nomp varchar2(20),+
+     nbg integer);+
+     /+
create type "professeurs_t" as table of professeur_t;
create type eleve_t as object (
+     nume integer,+
+     nome varchar2(25),+
+     nomc varchar2(5)+
+     );+
+     /+
create type "eleves_t" as table of eleve_t;
when I try to create another type with the following command
create type ecole1_t as object (
+     nomc varchar2(5),+
+     eleves eleves_t,+
+     professeurs professeurs_t );+
+     /+
I get the following error message:
Warning: Type created with compilation errors
checking with:
select type_name from user_types ;
indicates that the type has been created
but when I try to create a table on this type with this command :
create table ecole1 of "ECOLE1_T" (primary key (nomc))
+     nested table eleves_t store as elev,+
+     nested table professeurs_t store as prof;+
I get:
ERROR at line 1:
ORA-00902: invalid datatype
Please if you have an idea about what to do? help me ?
Thank you in advance

Hi,
If you enclose the name of a type (or a table, or a cloumn, or anything else) in double-quotes when you create it, then you generally have to enclose it in double quotes and spell it exactly the same way (case-sensitive) every time you use it.
Lose the double-quotes:
create OR REPLACE type eleves_t as table of eleve_t;
create OR REPLACE type professeurs_t as table of professeur_t;
/All identifiers in Oracle are case-sensitive. You may not realize that because all unquoted code (that is, everything not in suingle-quotes, like 'foo', or double-quotes, like "bar") is converted to upper case before it is compiled.
So when you said
create type eleve_t ...the type that was created was ELEVE_T, all uppercase, exactly as it appears in all_objects.
When you referenced it like this:
create type "eleves_t" as table of eleve_t;there was no error, because all the unquoted code got capitalized before compiling, so it's as if you had said
CREATE TYPE "eleves_t" AS TABLE OF ELEVE_T;Because it was quoted, "eleves_t" was not capitalized.

Creating type along or inside a path

Hi All,
I read the tutorial about Creating type along or inside a path. I have tried to create few types of type along,inside and outside a path and shape. I was wondering why there are variations and restriction among them. Below are my screen shots to describe my problem.
Screen 1

Sorry, I have been trying to upload the screen shots, now it is done.
Screen 1: type outside the path
Screen 2:type inside the path
Screen 3:type outside the shape
Screen 4:type inside the shape
I am confused why I cannot flip the "type inside the path" whereas flipping inside and outside is possible for "type outside the path". Any help is greatly appreciated. Thank you.
