SELECT TOP 10 (total_logical_reads/execution_count) AS [Média de leituras lógicas], (total_logical_writes/execution_count) AS [Média de escritas lógicas], (total_physical_reads/execution_count) AS [Média de leituras físicas], execution_count, plan_handle, (SELECT SUBSTRING(text, statement_start_offset/2 + 1, (CASE WHEN statement_end_offset = -1 THEN LEN(CONVERT(nvarchar(MAX),text)) * 2 ELSE statement_end_offset END – statement_start_offset)/2) FROM sys.dm_exec_sql_text(sql_handle)) AS [Texto da query] FROM sys.dm_exec_query_stats ORDER BY (total_logical_reads + total_logical_writes) DESC; |
