BUG #: 55626 (SQLBUG_70)
When you include @@IDENTITY in the WHERE clause of a SELECT statement, the Query Optimizer chooses to perform a table scan rather than using the appropriate index.
@@IDENTITY is not being recognized as a run-time constant.
Declare a variable, set it equal to @@IDENTITY, and then use the variable in the SELECT statement.
