Using like operator to check for pattern in hive

问题

I need to retrieve the columns from a hive table that must begin with uppercase letter and end with digit. I used this query

select * from tab1 where col1 like '[A-Z]%[0-9]';

But not able to retrieve the records ,getting only empty result.

回答1:

rlike / regexp

select * from tab1 where col1 rlike '^[A-Z].*[0-9]$';
