determination of the type of object

I have 2 classes inherit from the same class.

public abstract class ParentProps {
}

public class OneProps extends ParentProps {
}

public class TwoProps extends ParentProps {
}

I have another class that has a method that receives an argument of type ParentProps. How will I know if the argument is of the type OneProps or TwoProps?

public class Test {
   public static void testing(ParentProps props) {
   }
}

In the above example how can I know if the object the accessories is passed is a OneProps or a TwoProps object?

If (OneProps instanceof accessories)

[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.

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();
  -- insert your code here 

END;

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
Lavan

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.

What is the type of object to use for virtual machine model in the Points of Extension?

Hello
I added my plugin point of extension vsphere.core. ${objectType} .monitorViews. My plugin is for all types of objects (vm, file, vApp, resourcePool, etc) except the model of the virtual machine. My understanding is that the vm object type would be required for the virtual machine template, but that doesn't seem to be the case. Am I missing something here? Should the plugin appear for the model of the virtual machine when I use the vsphere.core.vm.monitorViews extension point?
Thanks in advance.
Kind regards
Ashutosh

Sorry, I got confused by your original question. ExtensionPoint id you are looking for is the one for adding views a model virtual machine monitor tab:

Determination of the Type of storage with PowerCLI

It is possible to determine the type of storage (Clariion, Symmetrix, etc.) with the identifiers of vml or naa? There is another way to determine the type of storage?

Thank you in advance.
Best regards!

Yes, it is possible.

You could do something like that

$storageVendors = @ {}

"60060480" ="EMC";

"60050768" ="IBM".

}

Get-VMHost MyEsx | Get-ScsiLun |

Select CanonicalName,

@{N = 'Seller'; E = {$storageVendors [$_]} CanonicalName.Split('.') {{[[1]. subString (0.8)]}}

You will have to compile a complete picture of the ID and sellers of course.

But I wonder why you wish to do this, since the information is already present

Get-VMHost MyEsx | Get-ScsiLun |

Select CanonicalName, seller

I do not know why you do what you do that is row-by-row (aka slow-by-slow), when you could do all this in a single merge - something like statement:

create or replace PROCEDURE P_UPDATE_RICA_COUNT_ID
   (A_PARTY_IDS IN T_PARTY_ID_LIST,
    A_ICAP_ID  IN number)
as
begin
  merge into sa_id_registration_counts tgt
  using (select x.id_type, x.id, count(*) cnt
         from   table(cast(a_party_ids as t_party_id_list)) x
         where  x.id_type in ('N', 'P', 'B')
         group by x.id_type, x.id) src
     on (tgt.id_type = src.id_type
         and tgt.id = src.id)
  when matched then
    update set no_of_registrations = no_of_registrations - src.cnt
  when not matched then
    insert (tgt.id, tgt.id_type, tgt.exclude_yn, tgt.no_of_registrations)
    values (src.id, src.id_type, 'N', 1);
end;

You v_id in your procedure, but you never defined anywhere, for as far as I could tell, so I made a few assumptions about the join condition. You will need to change if necessary.

Meanwhile, for your procedure, you should do something like:

DECLARE
  A_PARTY_IDS T_PARTY_ID_LIST := t_party_id_list();  -- initialised the collection here
  A_ICAP_ID NUMBER :=12323;
BEGIN  

  A_PARTY_IDS.extend(1);
  A_PARTY_IDS(1) := T_PARTY_ID(1,'1','1','1',null,null); 

  P_UPDATE_RICA_COUNT_ID(
      A_PARTY_IDS => A_PARTY_IDS,
      A_ICAP_ID => A_ICAP_ID );
end;
/

Another thing - you seem to like selection of the many double - if you're in PL/SQL, then you can just assign variables directly (overall; there are a few exceptions, depending on your version of the database).

Using the Type of object in fusion

Hi all

You have a small problem where I would like some suggestions.

I had a declared TYPE.

CREATE OR REPLACE TYPE 'MY_TYPE_OT' IS (OF THE OBJECT
Field1 VARCHAR2,
Field2 VARCHAR2,
field3 VARCHAR2);

I now have an array declared to type this

TYPE MY_TYPE_TT IS TABLE OF INDEX MY_TYPE_OT BY VARCHAR2 (100);

I have the collection of type MY_TYPE_TT

MY_TYPE_TT MY_VARIABLE;

I am populating this variable lets say 10 records.

Then I try to save it to a database table, my_table for this I need to merge since it could be an update or insert. so, my query goes like this

MERGE INTO my_table T2 using T1 ON (T1.field1 = T2.field1 AND T1.field2 = T2.field2) TABLE ($my_var)

Here, I get an error that my_variable is not a table. I tried different things like doing a casting, which gives me invalid data type etc.

Any suggestions on how to pick up on this?

Thanks in advance
Paddy

Collection with "index of" cannot be used in the context of sql. You can or use the collections without "index of" or treat it manually. See the example:

drop table MY_TABLE purge
/
CREATE OR REPLACE TYPE MY_TYPE_OT IS OBJECT (
field1 VARCHAR2(100),
field2 VARCHAR2(100),
field3 VARCHAR2(100))
/
create table MY_TABLE of MY_TYPE_OT
/
declare
  TYPE MY_TYPE_TT     IS TABLE OF MY_TYPE_OT INDEX BY VARCHAR2(100);
  MY_VAR              MY_TYPE_TT;
begin
  --just testing values for collection:
  for i in 1..3
    loop
      MY_VAR(i):=MY_TYPE_OT(null,null,null);
      MY_VAR(i).field1:='field1-'||i;
      MY_VAR(i).field2:='field2-'||i;
      MY_VAR(i).field3:='field3-'||i;
    end loop;

  -- manually merging by one row:
  for c in MY_VAR.first..MY_VAR.last
    loop
      execute immediate '
        merge into MY_TABLE T2
        USING (select :1 field1, :2 field2, :3 field3 from dual) T1
        ON (T1.field1 = T2.field1 AND T1.field2 = T2.field2)
        when matched then
          update set
                 t2.field3=t1.field3
        when not matched then
          insert values(t1.field1,t1.field2,t1.field3)
      '
      using MY_VAR(c).field1,MY_VAR(c).field2,MY_VAR(c).field3
    ;
    end loop;

CREATE OR REPLACE

PROCEDURE pr_update_user_role

FOR l_cnt IN ip_role_array. FIRST... ip_role_array. LAST

INSERT INTO cdr_md_user_role (cdr_md_user_role_seq_no,
role_cd,

VALUES (cdr_md_user_role_seq. NEXTVAL,
.role_cd ip_role_array (l_cnt),
ip_user_id);
...
AT THE END:
----------------------------------------------------------------------------------------------------------------------------
I don't understand what is this ip_role_array and how it is assigned to ROLE_TABTYPE.
I read documents to understand the use of these collections, but could not get.

Please, help me to understand this.

Rgds,
Aashish
It is just a collection (table): this is a variable that contains several values that are accessible using (1), etc. (2) refer to each value. This allows the calling procedure pass a set of values and have the loop of the procedure through the table and deal with each in turn. In case it starts with (1), ip_role_array. FIRST gives the first number of the element and ip_role_array. LAST give the last, so if there are 25 values in table 1, then the loop will be assessed as FOR l_cnt IN 1.25 LOOP.

determination of the types of image with FW CS3 files

Determine whether the instance of the object is of a specific object class.
I was not able to find the answer in the documentation or in the forum. My terminology is perhaps a bit off (Java and c# background back to PL/SQL programming).

The general question is: given an object instance how to determine if the type of the instance is of the same kind as a specific object class.

In particular, I do a unit test and examine the returned object instance. The effective yield is described as follows

-This data structure contains a pointer to an LDAP session
SESSION OF SUBTYPE IS RAW (32);

I expect an instance of DBMS_LDAP. SESSION. To confirm this, I propose that the returned pointer DEREF and see if it's a type of DBMS_LDAP. SESSION. When this is confirmed, then I can further the return of reference.

Draft code is

BEGIN
IF DEREF ({RETURN$}) some_operator_which_compares_object_types DBMS_LDAP. SESSION
THEN
RETURN TRUE;
ON THE OTHER
RETURN FALSE;
END IF;
END;

where some_operator_which_compares_object_types is what I need to know.

Thank you for your help. And of course, the other way to do business and/or links to the correct location in the documentation are appreciated.

Kind regards
