无法在HIVEQL中运行SELECT HAVING查询

Question

我在表格中有2列。让我们将它们称为A列和B列。我想找到A，其中B的非重复数大于1.在SQL中

select column_a
from table1
group by column_a
having count(distinct column_b) > 1;

出于某种原因，这不适用于HIVE。错误继续说

error while compiling statement: failed: semanticexception [error 10002]: line 4:22 invalid column reference 'column_b' 

Answer 1

你在运行什么版本的Hive？我想这个版本会很好用：

select column_a
from (select column_a, count(distinct column_b) as cnt
      from table1
      group by column_a
     ) a
having cnt > 1;

Answer 2

我终于使用

开始工作了

select column_a, count(distinct column_b)
from table1
group by column_a
having count(distinct column_b) > 1
