sqlserver解决tempdb过大的问题

sqlserver tempdb过大,是查询sql没有优化的结果

#查出最大的spid
use tempdb  
go  
SELECT top 10 t1.session_id,                                                      
t1.internal_objects_alloc_page_count,  t1.user_objects_alloc_page_count,  
t1.internal_objects_dealloc_page_count , t1.user_objects_dealloc_page_count,  
t3.login_name,t3.status,t3.total_elapsed_time  
from sys.dm_db_session_space_usage  t1   
inner join sys.dm_exec_sessions as t3   
on t1.session_id = t3.session_id   
where (t1.internal_objects_alloc_page_count>0   
or t1.user_objects_alloc_page_count >0  
or t1.internal_objects_dealloc_page_count>0   
or t1.user_objects_dealloc_page_count>0)  
order by t1.internal_objects_alloc_page_count desc  

#看是哪条sql导致的
select s.text,p.*
from master.dbo.sysprocesses p   
cross apply sys.dm_exec_sql_text(p.sql_handle) s  
where spid = 55
