Java SQL Server查询挂起在Mybatis中，但不在management studio中

我遇到了一个问题，我可以在SQLServerManagementStudio中运行查询，但当我从Mybatis运行查询时，相同的查询将挂起。活动监视器显示由查询启动的许多进程，这些进程似乎通过许多cxpacket和pageiolatch_sh等待相互计时

audit_player表有2.67亿行，player和playerInfo 350000和currency 20

你知道是什么引起的吗

select 'INS' as typeOfChange,
   p.playerId as "model.id"
   from Player p       
INNER join         
   (select DISTINCT(playerId) as playerId          
     from Audit_Player          
     where modifiedDate > '2012-11-14 14:35:47' and action in ('INS', 'UPD') and tester = 0) ap 
on p.playerId = ap.playerId       
left outer join PlayerInfo i on i.playerId = p.playerId       
left outer join Currency c on c.curName = i.curName where c.curCode <> 'XXX'       
UNION       
 select 'DEL' as typeOfChange,
   playerId as "model.id"
 from Audit_Player       
 where modifiedDate > '2012-11-14 14:35:47' and action = 'DEL'
