What happens when no value is inserted in an ENUM list?OptionsNothing happensThe code will crashA blank value is inserted in that caseNone of the above

When no value is inserted in an ENUM list in programming, particularly in languages like SQL (MySQL), the behavior depends on the context:

1. If you define an ENUM column and attempt to insert a row without specifying the value for that column, it will insert a NULL value (assuming the column allows NULLs) or the default value (if specified).

2. If no default value is specified and the ENUM column does not allow NULLs, it may result in an error when inserting a row without a value.

3. However, if the ENUM column has a default value and you do not specify any value during insertion, the default will be used.

Given the options:

1. Nothing happens
2. The code will crash
3. A blank value is inserted in that case
4. None of the above

The most appropriate answer here is A blank value is inserted in that case, assuming it refers to a default or NULL value. However, it is important to note that it actually depends on the specific implementation of the ENUM type and how the insertion is handled in that context.
