This is not a display format - it is a storage format. The database knows nothing about how to display the data, that is the function of the application that is connected to the database.

You're right, this is also a storage format. However, as far as I understood the question the application is Microsoft's enterprise manager or management studio -> you do not have the possiblitiy to change the display format without changing the storage format. If the original question did not regard to pre-built standard software but to individually developed software I aggree to you.

With such a vague question I can only really point you to the documentation:

* User Defined Functions[^]
* CREATE FUNCTION[^]

Does this help?

Hi!

It is not supported to build and execute a dynamic query in user defined functions. UDFs have to be deterministic -> no exec( @MyVar ) allowed.

Setting Password to the Database

22-Jun-06 0:55

Jeez - Use your imagination! I told you recently how to insert a graphic. And I told you that you convert it to a byte array in order to insert it in the database. The principle with a sound (or a word document, or a PDF, or a video, or an infinite number of other things) is exactly the same, as is the SQL needed. So long as you have a byte array of something you can store it in SQL Server in an image column. Just as I said already.

If you have some sound object and you need that in a byte array then that is no longer a SQL question and should be directed at the appropriate forum.

get list of active connections on a database

In that case ensure that your account is the only login that is granted access to that datbase.

Adding Auto-Increment ID in both parent and child table

Re: Adding Auto-Increment ID in both parent and child table

21-Jun-06 8:48

Hie,

I tried out samples in MSDN regarding how to enable autoincrement of an ID through Stored Procedure, it works. Now I'm having doubts where I wanted to insert the ID which is auto-incremented in parent table when a new record is added, to be inserted in the child table.
I just make an illustration for example, StaffAccount Table (Parent Table)having StaffID as primary key, it is auto-incremented using stored procedures-succesfully completed, now the StaffID is the foreign key in Login Table(Child Table), I want the StaffID to be added automaticallly in child table once a new record has been inserted in parent table.

How is this possible?

Thanks in advance for helping in reading this.
=)

Hi!

Your stored proc could look like this:

create procedure AddNewPerson
  @Name varchar(50)
as
  set nocount on

  insert into StaffAccountTable ( StaffName ) values ( @Name )
  insert into Login ( StaffID, ... ) values ( @@identity, ... )
go

Hope this helps.

Rainer

Hi Rainer,
thanks for the reply
but it seemed having some prob:
I had tried the stored procedure u had specify, but is generate error says that no null value can be inserted into the Login Table. Alright, I had set the StaffID in child table of Login AS Not Allow Null, I guess tis is the prob, but yet if i changed the setting to Set as Allow Null, the result the same- IT does not insert the auto-generated StaffID in (Staff Record)Parent Record to the (Login)child table.
Here is my Procedure

Create PROCEDURE InsertStaffAccount
@StaffName varchar(20),
@Gender char(10),
@Address varchar(50),
@Position varchar(20),
@Identity int OUT

AS
SET nocount On
INSERT INTO StaffAccount(StaffName,Gender,Address,Position) VALUES (@StaffName,@Gender,@Address,@Position)
INSERT INTO StaffLogin(StaffID,Password) VALUES (@@Identity,@Identity)
SET @Identity = SCOPE_IDENTITY()
go

any Idea??

It looks to me like the @Identity output parameter is the problem. It is NULL at the time that you insert into StaffLogin.

Are you trying to put a password into the StaffLogin table?

What value do you want the password to be?

yes, the password is one of the field in staffLogin table.
My intention is Once a new Staff Record is added, StaffID will be autogenerated and saved the new record in Staff Table.

In the same time, I wish the StaffLogin Table will be populated with the new StaffID as autogenerated in Staff Table and together with the password. Of course, since it is a new staff record, the Stafflogin table does not have the value of staffID and the password yet, it is added as a new record only in the same time as New Staff Record is added in the Staff Account. How is this possible?

The value of the password for the initial add record purpose is similar as the staffID which is auto-generated in the Staff Table, then i will add code to allow user to change the vaue of password on their first login.How is this possible?

thanks again
best regard

Hie EricDV

Thanks alot for the help. It really workos. The auto-generated staffID does populate the Login Table. But there is one weird thing, why the paswword seemed to have extra space infront of the StaffID? Eg. *****10011 * represent the space why is it so?
how to eliminate the extra space in front of the password??

thanks

You're welcome. Isn't this fun?

Yes. a few posts back, you defined your stored proc with these parameters:
@StaffName varchar(20),
@Gender char(10),
@Address varchar(50),
@Position varchar(20),
@Identity int OUT

You need to supply them when you call the procedure.

It depends on where you are executing it from. If you call it from the SQL Query Analyzer, then:

declare @iIdentity int<br />
<br />
exec InsertStaffAccount 'John Smith','Male','123 5th Street','CEO',@iIdentity out<br />
<br />
print @iIdentity

Are you trying to call it from C++,C#,VB.Net,ASP.NET???
