PHP警告：oci_fetch_all（）：ORA-01722：ORACLE PIVOT中的数字无效

Question

所以，我有一个查询，当我用客户端sql开发人员执行它时，我得到结果。

查询：

 select * from
    (
      select art_no, descr, store_no, stock
      from (
          select * from gr_rep.mmart_analysis@ss001 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss002 where disp_info in  ( '0','4' ) 
          union all 
          select * from gr_rep.mmart_analysis@ss003 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss004 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss005 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss006 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss007 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss008 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss009 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss010 where disp_info in  ( '0','4' )
          union all 
          select * from gr_rep.mmart_analysis@ss011 where disp_info in  ( '0','4' )
      ) x
    )
    pivot
    (
      sum(stock)
      for store_no in (1,2,3,4,5,6,7,8,9,10,11)
    )
order by art_no desc

结果：

当我使用像$res = oci_execute($p,OCI_NO_AUTO_COMMIT);这样的PHP运行时，$n = oci_fetch_all ($p, $res, null, null, OCI_FETCHSTATEMENT_BY_ROW);符合[04-Feb-2016 17:15:35 Europe/Athens] PHP Warning: oci_fetch_all(): ORA-01722: invalid number 我得到的结果：choices

有人可以伸出援助之手吗？
