| <indexterm audience="hidden">DROP VIEW statement</indexterm> |
| Removes the specified view, which was originally created by the <codeph>CREATE VIEW</codeph> statement. |
| Because a view is purely a logical construct (an alias for a query) with no physical data behind it, |
| <codeph>DROP VIEW</codeph> only involves changes to metadata in the metastore database, not any data files in |
| HDFS. |
