Problems with IDENTITY_INSERT Set to OFF? :-/

I'm trying to insert order details into my DB, and it keeps saying:


Cannot insert explicit value for identity column in table 'Orders' when IDENTITY_INSERT is set to OFF.


All I am trying to do is simply insert the users UserId into the UserId column, by using
WebSecurity.CurrentUserId
- Why is this not working?

I have:

dbase.Execute("INSERT INTO Orders
(UserId, OrderId, Status)
VALUES
(@0, @1, @2)",
WebSecurity.CurrentUserId,
Session["OSFOID"],
"Confirmed");`


So, as you can see, it's pretty simple. But, why won't it work?

My table definition is:

Answer

Unless you enable the ability to do identity-insert (by setting identity-insert on for that table), you are NOT ALLOWED to touch that column - the database owns it.

Either enable identity insert briefly, or: don't try to insert the UserId (let the DB create a new id).

As per books online, SET IDENTITY_INSERT:

SET IDENTITY_INSERT Orders ON
INSERT INTO Orders (UserId, OrderId, Status) VALUES (@0, @1, @2)
SET IDENTITY_INSERT Orders OFF

More likely, though: if this is the Orders table, should the identity not be on OrderId ? You'd still have the same problem since you are trying to control the OrderId, of course.
