OnDelete
When a delete command is applied to the original table, the DBMS may:
- Update the values in the tables concerned, with the Cascade option.
- Do nothing, with the NoAction option.
- Prohibit deletes, with the Restrict option.
- Reset to the default value in the tables concerned, with the Set Default option.
- Set the value to Null in the tables concerned, with the Set Null option.
