On a computer that is running Microsoft SQL Server 2008, consider the following scenarios.

Scenario 1

You specify a common table expression (CTE) by using the WITH statement. For example, you run the following query.
WITH common_table_expression AS 

(SELECT * FROM sys.objects)

(SELECT *

FROM common_table_expression)
Then, you run this query.
SELECT *

FROM sys.dm_exec_query_stats

WHERE statement_start_offset > statement_end_offset

AND

statement_end_offset <> -1
In this scenario, the cached query plan for this query stores incorrect statement_start_offset and statement_end_offset values. ????? ???? ???? ?????? statement_end_offset ???? ?? ?????? statement_start_offset ????? ???? ?????? ????? ??? ????? ???? sys.dm_exec_query_stats (DMV).

??? ???? ???????? ?? ???? ????? ???? ??? ??????? ????? ?? ???? ???? statement_start_offset ????? ??? ?? ???? statement_stop_offset.
