this is example but i dont know where to exicute the code (is it possible to have in sql server 2008?

Comparison to RDBMS

In an RDBMS, it would be fairly common to see SQL statements like this:
  CREATE TABLE Customers  (
      Id          CHAR(12)    NOT NULL PRIMARY KEY,
      Surname     VARCHAR(32) NOT NULL,
      FirstName   VARCHAR(32) NOT NULL,
      DOB         DATE        NOT NULL
   );
   SELECT InitCap(Surname) || ', ' || InitCap(FirstName)
     FROM Customers
    WHERE Month(DOB) = Month(getdate())
      AND Day(DOB) = Day(getdate())
which some OO fans would describe as overly complex logic. Furthermore, most current SQL databases allow the creation of custom functions, which would allow the query to be expressed as:
   SELECT Formal(Id)
     FROM Customers
    WHERE Birthday(Id) = Today()
In an object-relational database, one might see something like this, where the data types and expressions such as BirthDay() are user-defined.
   CREATE TABLE Customers (
     Id           Cust_Id     NOT NULL  PRIMARY KEY,
     Name         PersonName  NOT NULL,
     DOB          DATE        NOT NULL
   );
   SELECT Formal( C.Name )
     FROM Customers C
    WHERE BirthDay ( C.DOB ) = TODAY;

That query won't work in Sql, nor any database-implementation that I know of. It's either a relational, or an object-oriented database.

"Object relational" sounds like theory to me.

Some OO fans should do their homework. Relational is a way of modelling, like object-oriented. One can't become "more like" the other, since it's two different ways of looking at stuff.

Right.

Creating functions doesn't make it "object-relational".

There is no such thing as a "fuzzy" object oriented database. The example you lnked to does not apply to an existing product.

jojoba20 wrote:

Simply use SQL Server and you can create databases. Why does it need be "fuzzy"?

jojoba20 wrote:

..because you're looking for something that does not exist.

"Fuzzy object-relational"? What kind of data are you going to store that you're interested in that collection of buzzwords?

so how to use the code bellow ?
I wanna have Object Oriented DataBase (In an object-relational database, one might see something like this, where the data types and expressions such as BirthDay() are user-defined.)

this is example code for creating Table but give error in SQL Server Management 2008 !

CREATE TABLE Customers (
  Id           Cust_Id     NOT NULL  PRIMARY KEY,
  Name         PersonName  NOT NULL,
  DOB          DATE        NOT NULL
);



SELECT Formal( C.Name )
  FROM Customers C
 WHERE BirthDay ( C.DOB ) = TODAY;

Object-relational is nonsense.

jojoba20 wrote:

That's not example code, it's a made-up example. Sql Server is not an object oriented database and is not a fuzzy database. One talks to it using Sql, or using an ORM.

The example sql statement is a pack o' nonsense. I mean, convert C.DOB to a birthday? If you need a function, create one in SQL. There are dozens of manuals on how one creates a function and how to use that function in a query. Real examples, not converting X to X. Even the "formal" function is something that's standard SQL.

1) it's not a real life example
2) it's not real code
3) you don't need it

I'm convinced of 3 since you haven't named a single argument that says "need". I only read "want" from someone who cannot explain what it is he needs.

Have a read of this wiki page: Object Orientated database systems.[^]

as you can see the example you have been given come from here! the examples from this wiki page show that the SQL was and is written around database servers such as postgres etc.

The code like Eddy has said wont work on SQL Server!

The create table [^] statement is incorrect as you haven't specified the correct datatypes.

The Select statement wont work either, why? because you would need to create User definded functions[^] for Formal and BirthDay

for further reading Relational database systems (RDBMS)[^]

I have no experience with actually coding object orientated databases or even using them, I just know that they exist.

What I would suggest find out which database engine you are to use and then have a look at it's documentation.

It's called a witch-hunt. Did he make up this example himself, or did he simply come across something? It's a lousy way of researching.

Object oriented databases exist; you can download an open-source version and give it a whirl.

The query looks like he should be introduced to LINQ. Since it still does not explain what he is trying or needs, we can only guess. He's being "fuzzy", and will thus only receive fuzzy answers.

Hi,

I am using MySQL, PHP and PDO to insert a support ticket. Inserting works fine but I want to get the ticket_id after insertions using OUT from the stored procedure. Can you please help.

here is my stored procedure followed by my PDO code for INSERT.

SQL

CREATE DEFINER=`jassimdb`@`%.%` PROCEDURE `sp_add_new_ticket`(IN param_ticket_name varchar(255), IN param_ticket_email varchar(255), IN param_ticket_subject varchar(255), IN param_ticket_message text, OUT param_record_identity int)
BEGIN
	INSERT INTO support_tickets (ticket_guid, ticket_name, ticket_email, ticket_subject) VALUES (UUID(), param_ticket_name, param_ticket_email, param_ticket_subject);
	SET param_record_identity = LAST_INSERT_ID();
	INSERT INTO support_ticket_messages (ticket_id, support_ticket_message) VALUES (LAST_INSERT_ID(), param_ticket_message);
END

PHP

$mysql_query = $mysql_connection->prepare("CALL sp_add_new_ticket(:param_ticket_name, :param_ticket_email, :param_ticket_subject, :param_ticket_message)");
$mysql_query->bindParam(':param_ticket_name', $ticket_name, PDO::PARAM_STR);
$mysql_query->bindParam(':param_ticket_email', $ticket_email, PDO::PARAM_STR);
$mysql_query->bindParam(':param_ticket_subject', $ticket_subject, PDO::PARAM_STR);
$mysql_query->bindParam(':param_ticket_message', $ticket_message, PDO::PARAM_STR);

$mysql_query->execute();

Your primary key seems to be a GUID, not an auto-increment field. LAST_INSERT_ID only works for identity-fields.

Hi,

I am using PDO in MySQL to insert a ticket. I want to return the ticket number which is the primary key (auto increment) but it's always returning zero.

here is the code I am using:

PHP

$mysql_query = $mysql_connection->prepare("CALL sp_add_new_ticket(:param_ticket_name, :param_ticket_email, :param_ticket_subject, :param_ticket_message)");
// $mysql_connection->beginTransaction();

$mysql_query->bindParam(':param_ticket_subject', $ticket_subject, PDO::PARAM_STR);
$mysql_query->bindParam(':param_ticket_message', $ticket_message, PDO::PARAM_STR);

$mysql_query->execute();

$ticket_number = $mysql_connection->lastInsertId();
