在使用Mybatis进行SQL查询Oracle数据库时，如果SQL语句中存在重复定义的字段，会导致未明确定义列的错误。虽然在SQL工具中执行没有问题，但在Mybatis中执行该查询会出错。删除重复的字段后，问题得到解决。查询涉及到的表为HIS_STOCK_INFO，错误出现在STORE_UNIT,PHAR_UNIT,RETAIL_UNIT字段的重复定义上。

在此记录个BUG，mybatis的，SQL查询Oracle数据，SQL中重复定义查询了字段，就会导致报错未明确定义列，放到SQL工具中执行没问题，就是mybatis调用组装SQL后，再去查询数据，就要提示未明确定义列，但是又找不出是哪一个。删掉重复的就行了
