ATTACHMENT ID: 12748958 - PreCommit-HIVE-TRUNK-Build
> Broken processing of queries containing NOT (x IS NOT NULL and x <> 0)

>
> Key: HIVE-11375
> URL: https://issues.apache.org/jira/browse/HIVE-11375
> Project: Hive
> Issue Type: Bug
> Components: Logical Optimizer
> Affects Versions: 2.0.0
> Reporter: Mariusz Sakowski
> Assignee: Aihua Xu
> Fix For: 2.0.0
>
> Attachments: HIVE-11375.patch
>
>
> When running query like this:
> {code}explain select * from test where (val is not null and val <> 0);{code}
> hive will simplify expression in parenthesis and omit is not null check:
> {code}
> Filter Operator
> predicate: (val <> 0) (type: boolean)
> {code}
> which is fine.
> but if we negate condition using NOT operator:
> {code}explain select * from test where not (val is not null and val <>
> 0);{code}
> hive will also simplify thing, but now it will break stuff:
> {code}
> Filter Operator
> predicate: (not (val <> 0)) (type: boolean)
> {code}
> because valid predicate should be *val == 0 or val is null*, while above row
> is equivalent to *val == 0* only, filtering away rows where val is null
> simple example:
> {code}
> CREATE TABLE example (
> val bigint
> );
> INSERT INTO example VALUES (1), (NULL), (0);
> -- returns 2 rows - NULL and 0
> select * from example where (val is null or val == 0);
> -- returns 1 row - 0
> select * from example where not (val is not null and val <> 0);
> {code}
