Which data type character merges the "Check Constraint" into a data type definition?

Solution (By Examveda Team)

This question is about how to include a "Check Constraint" directly within the definition of a data type in MySQL. Check constraints are used to ensure that data entered into a column meets specific criteria.
Let's break down the options:
Option A: ENUM
ENUM is a data type in MySQL that allows you to create a list of predefined values for a column. It does not directly support Check Constraints.
Option B: ENUM1 and Option C: ENUM2
These options are not valid data types in MySQL.
Option D: None of the mentioned
This is the correct answer. MySQL does not have a data type that directly merges a Check Constraint into its definition. You would need to create the Check Constraint separately using an `ALTER TABLE` statement.
In Summary:
MySQL does not have a data type that merges Check Constraints directly into its definition. You need to create the Check Constraint separately.
