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.
=)
best regards amygal

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.
Regards,
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
amy

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

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???
