SYMPTOMS

Consider the following scenario:
  • You enable change tracking on a table in SQL Server 2008 or SQL Server 2008 R2.
  • The table has many rows. For example, the table contains over ten thousand rows.
  • You run a query that returns change tracking information about the table by using the CHANGETABLE function.
In this scenario, the query requires a long time to return results.
