With the help of a user defined type as a return type of function with a type of object

Hi, I created my own data type of table I want to use as data type back to a member function of an object type that I created.

I work in an environment of 10g.

The code I used looks like this:

create or replace
Dim p As Package as

type p_rec is (number of v1);
type p_tab is table of the p_rec;

end p;
/

CREATE or REPLACE TYPE p_ot () AS OBJECT

/ * some statements * /.

NO DEFINITIVE MEMBER FUNCTION p.p_tab RETURN foo

);
/

When I try to compile p_ot I get an error: Error (5.40): PLS-00201: identifier 'P.P_TAB' must be declared.

I don't know the syntax is correct so I must be missing something, amy hepl would be great.

See you soon

You can define types of objects

create type p_rec as object ( v1 number );
create type p_tab as table of p_rec;

They can be used inside the package (p) in your example) as well as defined in the package.
In this case, there will be no problems with create type

CREATE TYPE p_ot AS OBJECT (

/* some declarations*/

NOT FINAL MEMBER FUNCTION foo RETURN p_tab
);

Querying the user-defined types
I have a chart in which one of the columns is a user-defined data type:
```
SQL> describe my_table
...
USER_DATA    MYTYPE
```
The type 'MYTYPE' is a simple object that contains a field: a CLOB called MESSAGE:
```
SQL> describe mytype
Name       Null?    Type
------     -----    ----
MESSAGE          CLOB
```
When I do a "select *...» "in this table, the USER_DATA column appears as"MYTYPE (oracle.sql.CLOB@898c2d).

I know that for CLOB and BLOB fields, Developer SQL let me double click on the value and display the content. But for type like this defined by the user that contains a field, I can't navigate the data members of type. I find myself wanting to do something like a 'select user_data.message from my_table", but this is not a valid syntax. Is there a way to query a given specific member of this type defined by the user with the rest of the columns in the table, I can display the CLOB member instead of a representation of the object? If not, is it possible to configure SQL Developer to allow me to browse the data members of types defined by the user? TOAD has a feature like that but I would only use SQL Developer and it is a table that I work with on a regular basis.
csimons,

Try this:
```
select  t1.user_data.message
from    eimgr.aq_rtv_docs_out_table t1
where   rownum = 1;

Question of the user defined Type (UDT)

Hello

The attached file is NEITHER sample to call a VB6 vi.

The following is declared in the declaration section:

' Global declarations
Dim lvapp As LabVIEW.Application
Dim vi LabVIEW.VirtualInstrument

When I paste these statement in another project (that I'm working on), I get an error 'undefined user-defined type '.

Can someone point out to me were in the sample, these type definitions are declared?

Thank you

Rafi

PS the attachment is indeed xxx.rar and not xxx.zip. I changed the name because .rar has not been accepted. Please rename .rar

Thank you

I forgot to mark references to my project

retrieving data from columns of user defined type
Abstract types, I learned the other day. So I created an abstract type and a table.

Create the student_ty as an object type
(name varchar2 (20), number of roll);

create table result)
Student student_ty,
(total);

I also inserted data. But I'm having some trouble with the rretrieval of data. Suppose I want to choose only the roller and the name of the student as described in the type of studen. So I used the follwing query: -.

Select result student.name;

But it's not working. But when I use something like this: -.
Select r.total, r.student.name in result r;

This works perfectly. My question is that it is a rule that oracle needed to use an alias, whenever retrieve values for a user defined type data?. Help, please.
Thanks in advance.
Yes, you can use an alias when the type of object in a table like this.
```
select r.student.name, r.student.roll, r.total
  from result r
```

user-defined types

Hi all
I have a function that returns a type defined by the user in my sql environment. The type consists of 5 different columns. I pass a ref_id to my function, on the basis of which he does some calculations and returns me the type.
create or replace type my_type
(
number of col1,
col2 varchar2 (100),
COL3 varchar2 (10),
number of COL4,
number of col5
)
create or replace function fun (number in_id) return my_type
as
Start
-code1
-code2
Return (my_type)
end;
In my sql environment, I have a table which is the following structure
create table tab1
(
number of emeline
upgvc varchar2 (100),
number of Ref_ID, - this ref_id when it is passed to the function above will return a populated user-defined type values.
number of col1,
col2 varchar2 (100),
COL3 varchar2 (10),
number of COL4,
number of col5
)
I have a table tab2, using which i will be filling of the columns of the table tab1, tab2 table structure is as below
create table tab2
(
number of emeline
upgvc varchar2 (100),
number of Ref_ID)
now I have to fill each column in table tab1, tab2 table and my pleasure to feature.
something like
Insert into tab1
Select emeline,
upgvc,
Ref_ID,
Rest of the values must be completed by calling the function using the ref_id and fill in the values. What would be the best way to do it? I have millions of records with it. I tried to use this with the function of REGAL and tried fill lines, but its slow. All of the suggestions.
Note: apologies for not sticking scripts and the original code since it will take days
Thank you

How do I change my user type to be sufficient?

Oracle version 11.2.0.1.0
Thanks in advance!
>
How do I change my user type to be sufficient?
>
You will need to create two new TYPEs. The one who has all the columns of the draw. The REQUESTOR table and the new column SCORE, then a TYPE which is an array of the first type.

See example 12-22 using a Pipelined Table function for a Transformation in the PL/SQl language reference

http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/tuning.htm#i53120

Here's the first part
```
-- Define the ref cursor types and function
CREATE OR REPLACE PACKAGE refcur_pkg IS
  TYPE refcur_t IS REF CURSOR RETURN employees%ROWTYPE;
  TYPE outrec_typ IS RECORD (
    var_num    NUMBER(6),
    var_char1  VARCHAR2(30),
    var_char2  VARCHAR2(30));
  TYPE outrecset IS TABLE OF outrec_typ;
 FUNCTION f_trans(p refcur_t)
      RETURN outrecset PIPELINED;
END refcur_pkg;
/

CREATE OR REPLACE PACKAGE BODY refcur_pkg IS
  FUNCTION f_trans(p refcur_t)
   RETURN outrecset PIPELINED IS
    out_rec outrec_typ;
    in_rec  p%ROWTYPE;
  BEGIN
```
Change
```
  TYPE outrec_typ IS RECORD (
    var_num    NUMBER(6),
    var_char1  VARCHAR2(30),
    var_char2  VARCHAR2(30));
  TYPE outrecset IS TABLE OF outrec_typ;
```
to include all the columns you need. Unfortunately, you have to manually list all the columns in the draw. The REQUESTOR table. If you think you need this same structure in other places you must create them as SQL types instead of PL/SQL types.

This example should be enough to show you how to modify your code to do something similar.

Problem with the implementation of a user-defined function
Hello.
I wonder if you could help create a user function in ODI, which would do exactly the same thing as this one:

create or replace function Konwersja (psWejscie VARCHAR2) return DATE is
dDate DATE;
Start
dDate: = TO_DATE (psWejscie, ' DD month yyyy ',' NLS_DATE_LANGUAGE = POLISH ');
RETURN dDate;
EXCEPTION
WHILE OTHERS THEN
RETURNS A NULL VALUE.
END;

I tried to put Konwersja (psWejscie VARCHAR2) and Konwersja ($(psWejscie)) in the syntax and the rest in the implementation in Oracle syntax, but when I used it in an interface to load data to a date column (Konwersja (.)) (("" Data_U ")), I got an ORA-00923 exception
Yes, you can call this function from the DB interface directly. In the interface mapping column say Konwersja () it will work.

question of the decidability of oralce user defined rules

Hello
Accoring to some posts online (http://weblog.clarkparsia.com/2007/08/27/understanding-swrl-part-2-dl-safety/ http://protege.cim3.net/cgi-bin/wiki.pl?SWRLLanguageFAQ), in general, SWRL is undecidable. However, we can add some restrictions to SWRL to regain the decidability: Variables in DL security rules bind only to those explicitly named in the ontology. Add this restriction is sufficient to establish decidable SWRL rules. So, I wonder how the rules defined by the user Oracle reached the decidability. SWRL does adpot the simliar way? Thank you very much in advance.
Hong

Salvation Hong,

It is a good question. Yes, we have adopted a similar idea. Chaining before engine database Oracle database are the existing resources of RDF known variables in rules of deduction. We will not generate a new RDF resource that does not exist already in the ontologies. This is very important because it ensures that the inference process will be completed in a period of time.

The foregoing does not apply to the inference (a new 12.1) user-defined well.

Thank you

call a DLL that has the user-defined types

I am trying to call a function in a DLL that is
```
int32 system_config(&recCfg, &pulseCfg, errMsg)
```
recCfg is a structure consisting of 3 double rooms and 2 integers

and pulseCfg is a structure consisting of just Boolean

I don't know how to set the input parameters for this call the library feature.

LabVIEW sees as
```
void system_config(void)
```
I see the only choice of Numeric, Array, String, waveform, digital waveforms, digital data, ActiveX, Adapt to Type and pointer to Instance data for arg1. ActiveX seems to be the only one to use?
NYC says:

Actually contrary to what Simon says you can do in this case. But your line you are showing is unfortunately very unclear, because he does not understand the real typedef for your clusters. So I have to go by what you write in prose that is... Well... not very detailed.

The first is simply a cluster in LabVIEW with 3 floats to double precision, followed of 2 integers. You find yourself what bitsize integer, you need, as you do not show the typedef in the cluster. In order to connect to a cluster in a CLN you must configure this setting as to adapt to the Type. But be careful who does not work for clusters containing strings or arrays at all. Tables and chains of LabVIEW are something completely different than what awaits a C DLL. You can configure the parameters of function to be C compatible pointers to arrays and strings and LabVIEW will make sure to do the conversion on every call, but you cannot configure the CLN to convert strings and tables within a cluster.

The second group is really equivalent to a simple Boolean value passed by reference. As you do not show the actual type of the Boolean value, it is difficult to recommend this type of data to use in LabVIEW. Windows BOOL is a 32-bit integer and C++ bool is usually a 8-bit value which would coincide with the Boolean LabVIEW 8-bit use. You cannot configure a Boolean setting directly in the NLCS, so you can either use an integer of size accordingly or create this cluster with a single LabVIEW boolean anyway (if your bool is a bool C++ and not something else) and do the same as for the previous cluster/structure parameter.

Inserting data from the user-defined Type

Hi all

I have the following type

create or replace type answer_obj is object (all_employee_seq integer,questionseq varchar2(10),text_answer varchar2(4000),optionseq varchar2(10));

create or replace type answer_tbl is table of answer_obj;

I have the procedure (within a package) that pulls in the python papers.

TYPE answer_tbl_type IS TABLE OF question_answer%ROWTYPE
                               INDEX BY PLS_INTEGER;

PROCEDURE submit_survey (p_answers IN OUT answer_tbl)
   IS
      l_answers_tbl   answer_tbl_type;
   BEGIN
      FOR i IN p_answers.FIRST .. p_answers.LAST
      LOOP
         l_answers_tbl (i).all_employee_seq := p_answers (i).all_employee_seq;
         l_answers_tbl (i).questionseq := p_answers (i).questionseq;
         l_answers_tbl (i).text_answer := p_answers (i).text_answer;
         l_answers_tbl (i).optionseq := p_answers (i).optionseq;
      END LOOP;


      FORALL idx IN l_answers_tbl.FIRST .. l_answers_tbl.LAST
         INSERT INTO QUESTION_ANSWER
              VALUES l_answers_tbl (idx);
   
   END;

My question is, is it better to insert the data directly from the (record) (records) argument using for LOOP INSERT or the conversion of the argument in an associative array and a FORALL?
As you can see, it's a FOR LOOP to set the values in the array and then by the FORALL.

I think the above is even faster because of the first LOOP IS done in memory and real integration is carried out with FORALL.
I want to get as many opinions.

See you soon,.
Joel

Hello

Because you created the SQL Types, what just to do this within your procedure?

INSERT INTO QUESTION_ANSWER (all_employee_seq, questionseq, text_answer, optionseq)
SELECT all_employee_seq, questionseq, text_answer, optionseq
FROM TABLE(p_answers);

With the help of "allow users to dynamically add lines:
I want to know the opinion of the people, if it is an option, whether or not I have to light

I know that older versions using this option cause huge performance problems when users began adding lines.

Is this always the case. Should I understand a different approach? Can't present something to the populations of the user then turn around and take him away.
Not a fan or the other.

I have always managed to avoid this feature too - this thing that I really hate on this matter is that if you have multiple environments they will be out of sync, for this reason.

I found helpful to sometimes have a missing form of suppress, where users can create a block to make one see the line or data allowing to do the suppresed or rows to display.

Kind regards

Configure the read-access via user-defined privilege level

Hello everyone,

I m looking for the best configuration to restrict a user read-only. The restriction must be configured through CLI not GANYMEDE.

Material: 3750 (probably not interesting for that matter)

More old IOS: 12.2 (53) SE1

The user should be allowed to:
- See the running configuration
- trigger all sorts of orders-show
- Ping and traceroute of the device
The user should not be allowed to:
- Download/delete/rename files on the flash memory
- Enter the level 15 (not sure if I can avoid it)
- all orders despite those level 1 and those specified above
Can someone help me with this?

Thanks in advance!

I have won´t forgotten messages useful rates

Hi Tobias,.

You can

set up multiple levels of privilege on a switch as explained below.

By default, the Cisco IOS Software has two modes of password security: user EXEC and

Privileged EXEC. You can configure up to 16 levels of commands for each mode.

By configuring multiple passwords, you can allow different sets of users to have access to

specified commands.

For example, if you want many users to have access to the clear line command, you can

He attributed a level 2 security and distribute the level 2 password fairly widely. But if you

want more restricted access to the command configure, you can assign security to level 3

and distribute the password to a more restricted group of users.

Definition of the level of privilege for a command

Beginning in privileged EXEC mode, follow these steps to set the privilege level for a

control mode:

Purpose of command

Step 1

Configure the terminal

Enter global configuration mode.

Step 2

level privilege mode level control

Set the level of privilege for a command.

For mode, enter set for the global configuration mode, exec to EXEC mode, interface

for the interface configuration mode, or the line for line configuration mode.

For level, the range is from 0 to 15. Level 1 is normal user EXEC mode privileges.

Level 15 is the level of access allowed by the enable password.

For command, enter the command that you want to restrict access.

Step 3

activate the password level

Specify the password to enable for the privilege level.

. For level, the range is from 0 to 15. Level 1 is normal user EXEC mode privileges.

Password, specify a string from 1 to 25 alphanumeric characters. The string cannot

start with a number, is case sensitive and allows spaces but ignores leading spaces. By

by default, no password is defined.

Step 4

end

Return to privileged mode.

Step 5

Show running-config

or

Show privilege

Check your entries.

The first command shows the level of the password configuration and access. The second command

Displays the privilege level configuration.

Step 6

copy running-config startup-config

(Optional) Save your entries in the configuration file.

When you set a command to a privilege level, all commands whose syntax is a subset of this

control can also be programmed at this level. For example, if you set the show ip traffic command

level 15 show commands and show ip commands are automatically set to privilege level

15 unless you set them individually at different levels.

To return to the privilege by default for a given command, use the no privilege mode level

control of level global configuration command.

This example shows how to set the command configures to focus on level 14 and set

SecretPswd14 as the password users must enter to use 14 level controls:

Switch (config) # level 14 exec privileges set up

Switch (config) # enable password 14 SecretPswd14 level

You can also change the default privilege for every user level.

Change the level of privilege by default for lines beginning in privileged EXEC mode follow these steps to change the default privilege for a line level: complete order

Step 1 Configure terminal enter global configuration mode.

Step 2 line vty select the virtual terminal line to restrict access.

Step 3 privilege level change the default privilege for the line level.

For level, the range is from 0 to 15. Level 1 is normal user EXEC mode

privileges. Level 15 is the level of access allowed by the enable password.

End of step 4 back in privileged mode.

Step 5 show running-config or show privilege

Check your entries. The first command shows the level of the password configuration and access.

The second command shows the privilege level configuration.

Step 6 copy running-config startup-config (optional) save your entries in the configuration file.

Users can replace the privilege level that you set by using the privilege level line configuration command

you connect to the line and enabling a different privilege level.

They can lower the privilege level by using the disable command.

If users know the password to a higher privilege level, they can use this password to enable the higher privilege level. You can specify a privilege for your console line level to restrict the use of the line or high-level.

To restore the default line privilege level, use the no privilege level line configuration command. Also I send you a document for your reference.
