Lateral View in Hive

Learn how to use lateral views in Hive to apply table-generating functions and handle empty results.

You can use lateral views in Hive to work with user-defined table-generating functions (UDTFs), such as explode(). Lateral views generate output rows for each input row by applying the UDTF and joining the results with the original input row. Multiple lateral views can be used in a single query, referencing columns from preceding tables. Additionally, you can use the OUTER keyword to ensure rows are generated with NULL values when no output rows are produced.
