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

With the help of the socket object to retrieve data from web application without the html files

I tried to use the socket object to retrieve data from a web application (I just control script version vs version online). So all I want to do is access http://hyle.io/version that returns me the current version of the application (such as a simple string) in order to compare it in my script and then notifies the user accordingly. I have just a few problems using the socket object. I used this code from the Adobe Javascript Tools Guide:
```
reply = "";
conn = new Socket;
// access Adobe’s home page
if (conn.open ("www.adobe.com:80")) {
// send a HTTP GET request
conn.write ("GET /index.html HTTP/1.0\n\n");
// and read the server’s reply
reply = conn.read(999999);
conn.close();
}
```
... that I then adapted as:
```
reply = "";
conn = new Socket;
if (conn.open ("hyle.io:80")) {
  conn.write ("GET /version HTTP/1.0\n\n");
  reply = conn.read(999999); 
  conn.close();
}
```
And here is what I get:
```
HTTP/1.1 400 Bad Request
Content-Length: 225
Content-Type: text/html
Server: Pagodabox-Routing-Mesh

Bad Request
Your browser sent a request that this server could not understand.
Résultat : true
```
I don't know a lot about HTTP requests, but I wondered if it was related to the fact that I am not pointing to a specific HTML file and the type of request was wrong or if I should rather check if there is something wrong with my host?
The site/app is PHP and is hosted on PagodaBox if it helps.
Thanks in advance!

Hi Sebastien Lavoie,

It should work

var HTTPFile = function (url, port) {}

If (arguments.length == 1) {}

URL = arguments [0];

port = 80;

};

This.url = url;

This.port = port;

this.httpPrefix = this.url.match(/http:\/\//);

This.Domain = this.httpPrefix is nothing? This.URL.Split("/") [0] + ":" + this.port: this .url .split ("/") [2] +":" + this.port;

This.Call = ' GET ' + (this.httpPrefix == null? ' "). " http://" (+ this.url: this.url) + "HTTP/1.0\r\nHost: ' + (this.httpPrefix is nothing? "This.URL.Split("/ ") [0]: this .url .split (" / ") [2]) +" \r\nConnection: close\r\n\r\n ";

This.Reply = new String();

This.Conn = new Socket();

This.Conn.Encoding = "binary";

HTTPFile.prototype.getFile = {function (f)}

var typeMatch = this.url.match(/(\.) (\w{3,4}\b)/g);

If (this.conn.open (this.domain, "binary")) {}

This.Conn.Write (this.) Call);

This.Reply = this.conn.read (9999999999);

This.Conn.Close ();

} else {}

This.Reply = "";

}

(Return this.reply.substr(this.reply.indexOf("\r\n\r\n")+4);

};

}

Hyle var = new HTTPFile ("http://hyle.io/version");

Alert (hyle. GetFile());

And by the way, I like the idea of 'http://hyle.io'. Can you give me your email address, I want to learn more about this Web site.

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

In general, you will need to use an AJAX call to the server

It really depends on what the server returns as to how the information is easy to digest

JQuery provides a simple interface, and returns information easy to use

If you deal with things gets complicated XML according to namespace

If you look at the raw XML data and it goes something like fred: name you will have questions requiring an implementation of SAX - JSON is simple if you don't get that even if (nothing too confusing here)

If using an external data source JSON go if you have the choice

As examples go - just look to the top of JQuery Ajax [JSON / XML] and you will get where you're going quickly

SAX is MUCH harder because of the namespace - Dublin is the most common and same XML without namespace is not simple to handle, so avoid it if you can

does anyone know how we can retrieve data from staging of account using 'Segmentation Wizard', "report analysis tool", model of fusion and mailing, etc.?

Seems that these tools connect only to the production instance...

for segmentation Wizard (and perhaps other office files), you will have to go file - properties - Custom and update the values for the name of pod, if you have a job you know what value it is as I am not "have a practice to watch.

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.

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;
```
See you soon

SQL to retrieve data from the day before

Hello
I am asked to collect intelligence data and generate a daily report to determine the success rate (to do daily data that determines success rate). I have a session_time of column (with the DATE data type) that I try to do the job. I've been using:
Select * from ABC
where session_time > = TRUNC (SYSDATE - 2)
Gives me data, but I get the data from 26/10/14 and 10/28/14 so when I only need data on 27-10-14 (as of the day 28/10/14). I tried a few variations and did not get the expected result. Could someone please help me understand this? Time is also displayed in my outings, maybe I shouldn't include the time?
I use: TOAD for Oracle 11.5.1.2.

Use:

SELECT *.

ABC

WHERE session_time > = TRUNC (SYSDATE) - 1

AND session_time< trunc="">

;

It's 09:15 on October 28, 2014, then TRUNC (SYSDATE - 2) is 00:00:00 October 26; The query you posted became data of October 26 and later. (You may not all future dates in your table.)

If it's 09:15 October 28, then TRUNC (SYSDATE) is 00:00:00 October 28 (i.e., midnight, at the beginning of October 28) and TRUNC (SYSDATE) - 1 is 00:00:00 October 27.

Do not be tempted to use

WHEN TRUNC (session_time) = TRUNC (SYSDATE) - 1 * INEFFECTIVE! ***

It will get the same results, but it is slower, you cannot use an index on session_time and requires a call to separate function for each row in the table, it is selected or not.

Thank you best regards &,.
Castillo

Its seems quite surprising that no member of this forum suggests even a single code related to this problem...

However, I still have more research and find the alternative.
```
var contactResult = new Array();

var Fname = new blackberry.find.FilterExpression("firstName", "!=", "");

    contactResult = blackberry.pim.Contact.find(Fname);
    for ( var i = 0; i < contactResult.length; i++) {
        var totalName = contactResult[i].title+ " "+ contactResult[i].firstName+ " "+ contactResult[i].lastName;
        }
```
This will retrieve all data or contacts from the address book. For which I have to do a custom address book.

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
);
```
