Question

I am trying to use a NOT IN keyword in Hive Query Language. It seems to be giving me an error:

SELECT Name
FROM names_in_countries
WHERE Country = 'Mexico'
AND Name NOT IN (
    SELECT Name
    FROM names_in_countries
    WHERE Country <> 'Mexico')

Here is the original question with answer in SQL.

Answer 1

I don’t know Hive Query Language. Based on what I have read here: Hive Queries on Tables, following script might work. Give it a try.

Script:

SELECT      name
FROM        mytable
GROUP BY    name
HAVING      AVG((CASE WHEN country = 'Mexico' THEN 1 ELSE 0 END) * 1.) >= 1
