When no value is inserted in an ENUM list in databases (like MySQL), the behavior depends on the implementation of the database system and the specific configuration.

1. Nothing happens: This option is misleading because inserting a NULL or not providing a value will have a defined behavior.
2. The code will crash: This is unlikely as databases are designed to handle unexpected inputs gracefully.
3. A blank value is inserted in that case: Typically, if no value is inserted and the ENUM field is not set to NOT NULL, a NULL value may be stored. However, if the ENUM has no explicit default, it might just insert an empty value.
4. None of the above: This might be more accurate depending on specific context and settings.

Conclusion

The most accurate answer to the question is usually "A blank value is inserted in that case." However, it’s essential to refer to the specific database documentation and configurations to confirm the exact behavior.
