Creation of Collection Types

I understand that to create a collection type to define, and then to declare the variable. Definition of a collection type can be done using 'declare the type' and 'create the type' statement.

What is the difference between these two?

Thanks in advance.

How to use a collection type of variable binding to execute dynamic statement
Hello

We have a case where we copy selective data from A to B schema of schema in an oracle database. The copy is obtained using
run immediately 'insert'. target_schema |'. TableA select * from '. from_schema |'. where a.id table (select test_id of ' | from_schema |'.) Table c); " ;

It works very well it takes an average of 10 seconds to copy around 14 paintings. We have an obligation to bring this time to 2 seconds. An observation was the clause
"Select test_id of ' | '. from_schema |'. Table c"in the statement sql preceding repeats for many inserts. So, we thought bulk get this set of codes of practice and use a vatiable bind to collection for the immediate run clause type. Any suggestions on how to achieve this?

Thank you

problems with "importing the catalog" & "incompatibility of collection type.

I try to keep the 2 catalogues on 2 computers different sunchronized. I export photos
and collections (in fact a web gallery) from one computer to another, and
I get an error "collection type mismatch", which prevents the photos to be a
Bakery to the collection. I have exported and imported the flash gallery template
from one system to the other to ensure that the models are identical. A
LL as the photos, keywords and attributes seem to be imported correctly, but the photos are not added
to the collection. Anyone with successful export/import of collections between computers?
I use LR 2.7 on Win 7 and Vista.

No. I just quit using all special collections. Only the regular use. Hope it gets fixed in LR3 and I can reuse print collections.

Using TABLE() syntax with collection types
Hello

I created a function that returns a collection type in the TABLE of VARCHAR2.

Function works just fine:

SELECT * FROM TABLE (some_fcn ('VALUE1', 'VALUE2'));

Where I am passing static values.

However, I join it with another table, passing the values in this array as parameters:

SELECT f.some_table_key, t.* FROM une_table f, TABLE (some_fcn (f.col1, f.col2)) t;

When I do that, I get the error "ORA-00904:"F".» "Col1": invalid identifier.

I use 11 GR 1 material

Could someone please offer some advice with that?

Thank you!

Maybe things PIPELINED causing a problem?

Should be no problem.

You can also provide the structure of the table... there a column COL1 and COL2?

Data Modeler: how to create and use the collection type
Hello
essentially of departure I don't understand how (for example) create and use the data based on the type of data varray type.

Please notify.
Thank you
Andrew
Hi André,.

You can create new types of collection (varray/table) in two ways:
(1) in the browser - find 'Types of data' > 'Types of Collection' node menu dropdown - there just 'create new collection type' it
(2) in the types of data model diagram - you can create collection "some type structured" or collection of references to the it - use 'new Collection... '. "tool and click first on sight structured type and after the structured type that will contain the collection - new attribute is added to the latter and if there is none this type of collection already didn't set the new collection type are created and you can change it later.

Variable declaration of liaison for the collection type.
Hello

I have a procedue with collection (type) as output parameter.
How can I run the procedure of the SQL prompt.

Can I declare a variable binding in the form of a parameter that stores the type of collection.

Thanks and greetings

What are you talking about? Without doubt, one of the two generates a compile exception because the data type is incorrect...

Monica wrote:
STOP_STAT_RES is a collection of number abd the data types Date.

Do you mean that you have created a user-defined type (e.g. CREATE TYPE >) which has attributes NUMBER and DATE? And that STOP_STAT_RES is a collection of such user-defined? Can you post the this user-defined type declaration?

collection type parameter [11.2] based on the table in pipeline?

Hello
I have a collection of type "table of ' which is filled iteratively. (he gets the new entries more of a souce)
I need to sort the entries in this type of collection as well as the criteria.
My approach is to use a function table in pipeline which offers individual entries as lines for a "select from table (my_function (the_collection)).
My problem is that I get a compilation error in this query statement:
[Error] PLS-00382 (1209:70): PLS-00382: Dieser Lutherischen hat den falschen type-> expression is of the wrong type
[Error] PLS-00306 (1209:51): PLS-00306: wrong Anzahl oder Typen von illuminated by von call "ma_fonction"-> wrong number or type of arguments
[Error] ORA-00904 (1209:25): PL/SQL: ORA-00904: "my_package." "" ma_fonction "-> is not a valid identifier
but this feature is present in the package body and declared in the package header.
the entries in the collection are declared as record types in the package header
the collection of parameter type is declared as 'IS THE INDEX BY a_table.varchar2_attribute%TYPE my_record_type TABLE.
the package compiled until I added the request.
so my questions are:
1. What is the best way to sort the types of collection (by 2 attributes)?
2. how to pass a parameter of type of collection to a table of pipeliened function?
Good bye
DPT

This approach has proved to work well.

I created a temporary table to collect the data in. At this point, I use the MERGE statement to remove duplicates.

I sort everything in refetching this temporary table data.

Get the error during the creation of the type of the Schema element variable
Hello world

To create a variable of type of schema, I do the following steps...

Select 'Variables' after right-clicking on the bpel process. IN this window, go to 'Create VAriable' then select 'Element' type. Now in Type choose, I expanded the my imported schema files. And selected a type of item, and then click ok to create this variable. I get the message...
TO SAVE ANY WSDL/SCHEMA FILES, YOU MUST HAVE A PARTNER LINK LOCATED IN THE DIRECTORY OF THE CURRENT PROJECT.

Which is to say by whom.
I imported the schema files in the project. After that I imported in the WSDL file also. Now why I am getting error during the creation of the variable. However, I can create variable directly in. BPEL file, then everything is fine. And it works too. But what is average with the error above? Why I am not able to create the variable via GUI?

Thank you.
Hello

I have this same problem this morning, and I was going crazy, until I found this Web page on the internet:

The idea is that the jdeveloper is not very good with directories with spaces to work on the directory name. If you move all your work in a directory without spaces, it will work smoothly. At least, it worked for me.

assign a collection type to a record...

I have a this following:

CREATE TABLE odp_test
(char_1, VARCHAR2 (10))
char_2 VARCHAR2 (100),
num_1 NUMBER (5.0).
dec_1 NUMBER (8.2))
/

CREATE OR REPLACE
type odp_test_o as object)
char_1 VARCHAR2 (10),
char_2 VARCHAR2 (100),
num_1 NUMBER (5.0).
dec_1 NUMBER (8.2))
/

CREATE OR REPLACE
type odp_test_t as the odp_test_o table
/

I get a the collection - odp_test_t as an entry in a PL/SQL procedure. I then try to treat each line in the collection and insert it into the odp_test table. I was hoping to assign each element to a file defined as l_rec odp_test % ROWTYPE - but this does not (incompatible data types).

So - I was wondering how to (without having to assign the individual elements of the collection to check) the collection assigned to a type of usable data (record or row in a PL/SQL associative array)...

Any help is appreciated!

Thank you.

So what's the problem:

SQL> CREATE TABLE odp_test
  2  (char_1 VARCHAR2(10),
  3  char_2 VARCHAR2(100),
  4  num_1 NUMBER(5,0),
  5  dec_1 NUMBER(8,2))
  6  /

Table created.

SQL>
SQL> CREATE OR REPLACE
  2  type odp_test_o as object(
  3  char_1 VARCHAR2(10),
  4  char_2 VARCHAR2(100),
  5  num_1 NUMBER(5,0),
  6  dec_1 NUMBER(8,2))
  7  /

Type created.

SQL> CREATE OR REPLACE
  2  type odp_test_t as table of odp_test_o
  3  /

Type created.

SQL> DECLARE
  2      v_odp_test_t odp_test_t := odp_test_t();
  3  BEGIN
  4      v_odp_test_t.EXTEND(2);
  5      v_odp_test_t(1) := odp_test_o('A1','A1',1,1);
  6      v_odp_test_t(2) := odp_test_o('A2','A2',1,1);
  7      INSERT
  8        INTO odp_test
  9        SELECT  *
 10          FROM  TABLE(v_odp_test_t);
 11  END;
 12  /

PL/SQL procedure successfully completed.

SQL> SELECT * FROM odp_test
  2  /

CHAR_1     CHAR_2          NUM_1      DEC_1
---------- ---------- ---------- ----------
A1         A1                  1          1
A2         A2                  1          1

As you can see, there is no need to assign each item to a folder defined as l_rec odp_test % ROWTYPE.

Creation of Data Type when the script crashes LabVIEW

When you use the script (LV2010) if I call the Create method of Data Type (available appeal node when a reference to the BD is cable), if I have all but 1 up to the wiring on 'style' terminal, LabVIEW, it blocks. LabVIEW then restarts with an error message saying that "the last time that you have run LabVIEW internal error or accident took place in lvmain.cpp, line 1756. If I have wiring 1 However, it creates a constant fine.

I see in the context-sensitive help that it always creates a control at the start, but it seems that I can't get it to create a constant. So, okay, I decided to go around, create the constant, take the new object refnum he returned and there to change the constant in one control... but I can't get this work. Can someone point me in the right direction? Here is the code and the screenshot; This is a quick drop plugin.

It is intended to run on a cluster that is perceived as an icon if you want to test, you need to create that.

I presented the 'style' value, 0 if if you don't want to plant LabVIEW, set it up to 1.

No time for an in-depth exploration now. Create from Datatype killed my LV10. What I was able to do after creating a constant of cluster, the consultation as an icon and select it. (1) with the scripts, create a new VI and stick that the constant to figure (2) mount the pasted objected to the ClusterConstant and the change of control.

I think I know where you're going, should be interesting.

Creation of Collection of Query question
Hello

I have a process page that creates a collection by using the create_collection_from_query method. One of the columns being withdrawn in the collection that I would like to filter based on a page element. For example:

() apex_collection.create_collection_from_query
p_collection_name = > 'WRKHRS_COLL ',.
p_query = > ' SELECT ID
EMPLOYEE_NUMBER
EMPLOYEE_NAME
DATE_OF_WORK
ACCOUNT_CODE
HOURS_WORKED
HOURLY_RATE
WEEK_NUM
APPROVED
Original_record "O"
wwv_flow_item.md5 (ID,
EMPLOYEE_NUMBER
EMPLOYEE_NAME
DATE_OF_WORK
ACCOUNT_CODE
HOURS_WORKED
HOURLY_RATE
WEEK_NUM
APPROVED)
OF T_SMT_WORKRECORDS
WHERE EMPLOYEE_NUMBER =: P1_SELECTED_EMPLOYEE'
,
p_generate_md5 = > "YES");

This results in the following error message:

ORA-20104: create_collection_from_query error: ORA-20104: create_collection_from_query ExecErr:ORA - 01008: not all variables

I tried to escape from the reference point of page using v ('P1_SELECTED_EMPLOYEE'), using = "' | : P1_SELECTED_EMPLOYEE | "' etc, etc.

I'm wasting my time? I'd be surprised if there were not up to move a page item to the create_collection_from_query method.

Hello user979731 (please tell us your name - we are a friendly bunch).

Have you tried that?
```
apex_collection.create_collection_from_query(
p_collection_name => 'WRKHRS_COLL',
p_query => 'SELECT ID
, EMPLOYEE_NUMBER
, EMPLOYEE_NAME
, DATE_OF_WORK
, ACCOUNT_CODE
, HOURS_WORKED
, HOURLY_RATE
, WEEK_NUM

, HOURLY_RATE
, WEEK_NUM
, APPROVED)
FROM T_SMT_WORKRECORDS
WHERE EMPLOYEE_NUMBER = ' || :P1_SELECTED_EMPLOYEE,
p_generate_md5 => 'YES');
```
I can't test it now (I have to go) but let me know if it helps.

Creation and collection display
I'm new in APEX.

I add on the page processes: "on the charge before the header:

apex_collection.create_or_truncate_collection
(p_collection_name = > 'ORDER_MAIN');

(With SQL Developer) do query:

Select *.
of APEX_COLLECTIONS

result - 0 selected lines

Who is wrong? The collection is not created?
To view the collection create a select sql with your query report on the collection. Extensive collection is limited to the session. You can also view the collection by using the following steps.

Run the Page
Click the session menu on the developer tools toolbar
SELECT the view drop-down list collections
Click OK.

Problem with file .rar (CS6 Master Collection) type

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.
