Description
Hive: Select query with IS operator is producing unexpected result.
The following was executed on postgres:
sqlancer=# create table if not exists emp(name text, age int); CREATE TABLE sqlancer=# insert into emp values ('a', 5), ('b', 15), ('c', 12); INSERT 0 3 sqlancer=# select emp.age from emp where emp.age > 10; age ----- 15 12 (2 rows)sqlancer=# select emp.age > 10 is true from emp; ?column? ---------- f t t (3 rows)
This is happening because IS operator has higher precedence than comparison operators in Hive. In most other databases, comparison operator has higher precedence. The grammar needs to be changed to fix the precedence.
