带有Hive的“IN”子句中的多列

Question

在下面的“IN”子句中，hive是否支持多列的查询？

select * from address where (se10,ctry_nm) IN (44444444,"USA");

我在这个查询中得到以下错误 -

FAILED：表达式规范中的'se10'附近的ParseException行1:33不匹配的输入'，'期待'

Answer 1

不。如果您将两列与两个值进行比较，根据您的要求，简单的=就足够了.AND或OR。

select * from address where se10 = 44444444 and ctry_nm = "USA";

或者在Hive 0.13中

select * from address where se10 in (44444444) and ctry_nm in ("USA");

Answer 2

我会做

SELECT * 
  FROM address 
 WHERE CONCAT(se10,ctry_nm) IN ('44444444USA');
