问题
I'm a noobie here. I'm trying to retrieve top 2 tables from my employee list based on salary in hive (version 0.11). Since it doesn't support TOP function, is there any alternatives? Or do we have define a UDF?
回答1:
Yes, here you can use LIMIT.
You can try it by the below query:
SELECT * FROM employee_list SORT BY salary DESC LIMIT 2
回答2:
select * from employee_list order by salary desc limit 2;
