design of a process

I'm going to design a web page for students parking permit application.I'm new to asp.net, I have a process in mind doing it like this:

The form asks student to choose a permit type, then fill in applicant info, like name, grade, vehicle info, student may have 2 vehicles, and payment method, check or credit card,

I plan to create 3 tables like tblPermit, tblapplicant, tblVehicle.

After the students fill in the form, click submit button, I pass the values and call a stored procedure, some thing like this.Dim CmdAsNew Data.SqlClient.SqlCommand(MySQL, MyConn)

Cmd.CommandType = Data.CommandType.StoredProcedure

Then in the stored proceudre, I will do :

Begin

insert into Permit table, then get permitID, by using something like this:

Select @.PermitID=@.@.Identity

Then insert into Student table,then use

Select @.StudentID=@.@.Identity

Then insert into vehicle table.

All the above 3 processes I put it in begin, end--So that they will not messed up with other applicants data.

I think begin...end is one transaction.

SO am I doing correctly this way? Thanks

Begin...End doesn't signify a transaction, it signifies a code block. The idea is basically correct, but use SELECT @.PermitID=SCOPE_IDENTITY() instead. You should also wrap the whole thing in a transaction to be safe.

So shall I use something like this:

AS
Begin

Begin transaction
Set NoCount on
DECLARE @.PermitID INT
Insert table............

Commit Transaction

End

Can I use the begin transaction ...commit transaction in Begin ......end, or no need of begin..end.

Thanks
