| Query goal: | Find updatable views that restrict rows, i.e., have WHERE clause, but do not have WITH CHECK OPTION constraint. WITH CHECK OPTION constraint prevents updates through the view that violate the predicate of the view. Such updates must be prevented. |
| Query type: | Problem detection (Each row in the result could represent a flaw in the design) |
| Query reliability: | High (Few or no false-positive results) |
| Query license: | MIT License |
| Data source: | INFORMATION_SCHEMA only |
