recompile后在sys.dm_exec_query_plan(s1.plan_handle)中查不到QueryPlan，这样就没有cache，so，下次执行时重新生成queryPlan。

select * from ds_stg.tr_sec option(recompile)

select top 100 Query_plan,
 Creation_time ,
 Last_execution_time ,
 Execution_count ,
 Last_rows,text,*
from
 sys.dm_exec_query_stats s1
 cross apply sys.dm_exec_sql_text(sql_handle) as s2
 CROSS APPLY sys.dm_exec_query_plan(s1.plan_handle) qp
 where text like ‘select * from ds_stg.tr_sec%‘
