According to the docs it will return the identity produced by the
current statement if selected within the same statement. Although I seem
to recall from the good old days (SQL Server 6.x) that this was not
always the case in high load environments.

See SQL Docs:

Returns the last-inserted identity value.


Return Types

After an INSERT, SELECT INTO, or bulk copy statement completes,
@@IDENTITY contains the last identity value generated by the statement.
If the statement did not affect any tables with identity columns,
@@IDENTITY returns NULL. If multiple rows are inserted, generating
multiple identity values, @@IDENTITY returns the last identity value
generated. If the statement fires one or more triggers that perform
inserts that generate identity values, calling @@IDENTITY immediately
after the statement returns the last identity value generated by the
triggers. The @@IDENTITY value does not revert to a previous setting if
the INSERT or SELECT INTO statement or bulk copy fails, or if the
transaction is rolled back.

@@IDENTITY, SCOPE_IDENTITY, and IDENT_CURRENT are similar functions in
that they return the last value inserted into the IDENTITY column of a

@@IDENTITY and SCOPE_IDENTITY will return the last identity value
generated in any table in the current session. However, SCOPE_IDENTITY
returns the value only within the current scope; @@IDENTITY is not
limited to a specific scope.

IDENT_CURRENT is not limited by scope and session; it is limited to a
specified table. IDENT_CURRENT returns the identity value generated for
a specific table in any session and any scope. For more information, see
