返回做IO数目最多的50条语句以及它们的执行计划

select top 50 (total_logical_reads/execution_count) as avg_logical_reads,
(total_logical_writes/execution_count) as avg_logical_writes,
(total_physical_reads/execution_count) as avg_phys_reads,
Execution_count,
statement_start_offset as stmt_start_offset,
statement_end_offset as stmt_end_offset,
substring(sql_text.text, (statement_start_offset/2),
case when (statement_end_offset -statement_start_offset)/2 <=0 then 64000
else (statement_end_offset -statement_start_offset)/2 end) as exec_statement,
sql_text.text,plan_text.*
from sys.dm_exec_query_stats 
cross apply sys.dm_exec_sql_text(sql_handle) as sql_text
cross apply sys.dm_exec_query_plan(plan_handle) as plan_text
order by (total_logical_reads + total_logical_writes) /Execution_count Desc
