sql – 在Hive查询中的子查询源中

我在Hive上运行查询类似于：

SELECT *
FROM (SELECT a
      FROM b
      WHERE
      sex = 'M'
      AND   degree = 'Bs'
      AND   age = 15
      AND   name LIKE 'L%'
      );

错误是：

cannot recognize input near '<EOF>' '<EOF>' '<EOF>' in subquery source

解决方法

为Hive添加子查询的表别名是必需的.下面我使用’t1’作为别名：

SELECT *
FROM (SELECT a
  FROM b
  WHERE
  sex = 'M'
  AND   degree = 'Bs'
  AND   age = 15
  AND   name LIKE 'L%'
  ) t1 ;
