What is the dynamic mapping feature in MyBatis?

Dynamic mapping feature in MyBatis allows for the generation of SQL statements based on different conditions, enabling flexible database operations. With dynamic mapping, data can be inserted, updated, deleted, or queried dynamically based on runtime conditions, resulting in more flexible database operations. Typically, dynamic mapping functionality can be achieved using dynamic SQL statements in MyBatis, such as using if, choose, where, trim tags to generate different SQL statements based on conditions. This helps reduce redundant code writing, improving code maintainability and flexibility.
