Question

我有两组不同的表。我想比较两个表中的总数，并想显示两个表中的计数是否匹配。如果匹配，则“通过”，否则为“失败”。

SELECT (SELECT COUNT (*)
          FROM Table1  t1
               INNER JOIN Table2 t2
                   ON TRIM (t1.mgac_ac_id) = TRIM (t2.account))
           AS cnt1,
       (SELECT COUNT (*) FROM t3) AS cnt2            where cnt1=cnt2;

以上显示代码不正确。任何人都可以在代码方面提供帮助。是否要在HIVE中创建任何变量？

好，完成此操作很简单。如下所示：

select 
    case when tmp1.value = tmp2.value then 'Pass' else 'Fail' end as result
from
    (select count(1) as value from table1) tmp1
join
    (select count(1) as value from table2) tmp2 on 1=1

HIVE中的两个表比较
