| `CREATE EXTERNAL WEB TABLE` creates a web table definition. Web external tables allow HAWQ to treat dynamic data sources like regular database tables. Because web table data can change as a query runs, the data is not rescannable. |
| |
| You can define command-based or URL-based web external tables. The definition forms are distinct: you cannot mix command-based and URL-based definitions. |
