我在hive上运行查询....似乎是从日志，它失败，因为表[date_dim]中的错误记录导致转换异常....当我在[date_dim]中查找其他记录时，没有什么不同特定记录（最后参见样本记录）。
指向特定记录我可能是错的...试图理解为什么会出现这种投射错误以及如何解决这个问题？
你能帮我理解为什么这个特殊记录的错误？怎么解决？ 任何帮助都非常感谢!!!
Hive查询：
SELECT 'store' AS channel, 'ss_cdemo_sk' AS col_name, d_year, d_qoy, i_category, ss_ext_sales_price AS ext_sales_price
FROM store_sales , item , date_dim
WHERE ss_cdemo_sk IS NULL
AND ss_sold_date_sk = d_date_sk
AND ss_item_sk = i_item_sk ;
