> Key: TEIID-4316
> URL: https://issues.jboss.org/browse/TEIID-4316
> Project: Teiid
> Issue Type: Bug
> Components: Misc. Connectors
> Affects Versions: 8.12.5
> Reporter: Jan Stastny
> Assignee: Ramesh Reddy
>
> For columns, which contain some null values, a query like:
> {code:sql}
> SELECT nullable_column FROM table_name WHERE nullable_column <> some_value
> {code}
> doesn't return null values.
> Simple select works:
> {code:sql}
> SELECT nullable_column FROM table_name
> {code}
> returns all rows regardless whether they are null or not.
> IS NULL criteria in WHERE clause also work:
> {code:sql}
> SELECT nullable_column FROM table_name WHERE nullable_column IS NULL
> {code}
> returns correct number of null values.
