problems width select line

[Christopher Brandsdal]

Hi!

I am having some problems width a little script i downloaded...

I'm not able to figure out what he SELECT line does!
What does the @@identity mean?
Is this maby a javascript? :)

function GetLastIdentity(ADOConnection)
{
var rstIdentity = Server.CreateObject("ADODB.Recordset");
rstIdentity.Open("SELECT @@identity AS IdentityId", ADOConnection);
var iIdentity = rstIdentity.EOF == false ? rstIdentity("IdentityId").value : -1;
rstIdentity.Close();
return iIdentity;
}

An explanation of what @@IDENTITY is can be found here.

@@IDENTITY is a SQL Server variable representing the last inserted IDENTITY value for this connection's session (that's a SQL Server session, not an ASP session).

In this case, the GetLastIdentity() function would be of very little use
unless it is called directly after a barebones INSERT statement.

If you're using SQL Server 2000, SCOPE_IDENTITY() is safer than @@IDENTITY, since the latter is vulnerable to chained inserts (e.g. a trigger on the
object table that, in turn, inserts into another table with an IDENTITY
column).

There are lots of things I don't know. There is only one thing that Aaron
doesn't know though - euphemismic conversation. :P
