如何清除倒在SQL Server 2005/2008查询执行统计

Question

根据使用本柱获得该SQL的非常有用的片获得查询执行统计大多数中执行存储过程 - 堆栈溢出：

SELECT TOP 100
   qt.TEXT AS 'SP Name',
   SUBSTRING(qt.text, qs.statement_start_offset/2, CASE WHEN (qs.statement_end_offset = -1) THEN LEN(qt.text) ELSE (qs.statement_end_offset - qs.statement_start_offset)/2 END) AS actual_query,
   qs.execution_count AS 'Execution Count',
   qs.total_worker_time/qs.execution_count AS 'AvgWorkerTime',
   qs.total_worker_time AS 'TotalWorkerTime',
   qs.total_physical_reads AS 'PhysicalReads',
   qs.creation_time 'CreationTime',
   qs.execution_count/DATEDIFF(Second, qs.creation_time, GETDATE()) AS 'Calls/Second'
FROM sys.dm_exec_query_stats AS qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS qt
WHERE qt.dbid = (SELECT dbid
                FROM sys.sysdatabases
               WHERE name = 'BSP')
ORDER BY qs.total_worker_time/qs.execution_count DESC

我将如何彻底清除这些执行统计和从头开始？

这将是特别有用的发展缺陷和测试有引起例程被称为通常较大的次数从而伤病退役的真正的使用水平。
