google到解决办法，说是11.2.0.4的一个小bug，需要设置一个事件才能避免

SQL> ALTER SESSION SET EVENTS ‘31156 trace name context forever, level 0x400‘;

Session altered.

OK，可以执行成功了，如下所示：

SQL> 
select count(cl.cont_ledger_id) from cont_ledger cl 
 inner join project_project pp on cl.project_cd=pp.org_cd
  inner join res_approve_info rai on rai.res_approve_info_id=cl.res_approve_id
   inner join res_approve_content rac on rac.res_approve_info_id=rai.res_approve_info_id
  where cl.enable_flg=‘1‘  and pp.is_virtual=‘0‘
  and cl.created_date>to_date(‘2016-01-01‘,‘yyyy-mm-dd‘)
  and cl.created_date<to_date(‘2017-01-01‘,‘yyyy-mm-dd‘)
  8     and extractvalue(xmltype(rac.approve_content), ‘/templet/content/isMonopoly‘) =‘true‘;

COUNT(CL.CONT_LEDGER_ID)
------------------------
