这里比较明显由于DELETE FROM wri$_adv_sqlt_rtn_planWHERE这条sql语法不对，导致无法解析因此报了ORA-00933错误,通过人工执行

SQL>  exec SYS.PRVT_ADVISOR.DELETE_EXPIRED_TASKS();

PL/SQL procedure successfully completed.

后台alert日志重现该错误，证明该程序本身有问题，属于oracle bug范畴，查询mos发现相关Bug 26764561 : ORA-00933 IN SYS.WRI$_ADV_SQLTUNE.SUB_DELETE_EXECUTION
