oracle 11g 版本出现的字段查询诡异问题及解决办法

先贴上查询语句

WITH resultTable AS              (
      SELECT b.STAND_CFG_PRI_ID,
        b.PRODFAM_ID,
        b.PRODFAM_CODE,
        b.PRODUCT_LINE_ID,
        b.PRICE_LOOUP_TYPE,
        b.PRICE_LOOUP_CODE,
        b.STAND_CFG_CONST,
        b.SALES_CHANNEL_TYPE,
        b.SALES_CHANNEL_CODE,
        b.PRICE,
        b.MATER_COST_PRICE,
        b.PRODU_COST_PRICE,
        b.UNITS,
        b.CURRENCY,
        b.CREATE_BY,
        b.ENABLE_FLAG,
        b.REGISTER_ID,
        TO_CHAR(b.CREATE_DATE,'YYYY-MM-DD') AS CREATE_DATE,
        b.LAST_UPDATE_BY,
        TO_CHAR(b.LAST_UPDATE_DATE,'YYYY-MM-DD') AS LAST_UPDATE_DATE,
        scp.ekp_order_type
      FROM ECC_OC.STAND_CFG_COST_PRICE_V b,
        ECC_OC.STAND_CFG_PRICE scp
      WHERE b.ENABLE_FLAG      ='T'
      AND scp.STAND_CFG_PRI_ID = b.STAND_CFG_PRI_ID
      AND b.PROD_LINE_CODE     ='PL_DZB'
      AND b.PRICE_LOOUP_CODE   ='CONFIG_SALES_PRICE_CODE'
      ORDER BY b.CREATE_DATE
)          
SELECT result.* FROM            
(     SELECT * FROM         
    (                       SELECT resultTable.*,viewTable.*,ROWNUM AS resultNums                        FROM resultTable , (SELECT Count(1) AS resultCount FROM resultTable) viewTable  
    ) 
) result

整个查询中，只有那个红色的字段有问题，原因很可能是  ECC_OC.STAND_CFG_COST_PRICE_V b 这个视图，本来就包含了ECC_OC.STAND_CFG_PRICE scp里面的某些字段，然后再复杂的查询下，11g bug了。。
解决方法是：把optimizer_features_enable设成10g。 语句如下：
alter system set optimizer_features_enable = "10.1.0.5" scope=both;
