MyBatis Set Tag: Dynamic Updates Explained

In MyBatis, the set tag is used to specify the fields and their corresponding values that need to be set in an update statement. Using the set tag allows for dynamically setting the fields that need to be updated in the statement, rather than updating all fields with fixed values. This improves the flexibility of update statements, reduces the number of fields that need to be updated, and prevents unnecessary update operations due to unchanged field values. By using the set tag, it is possible to dynamically set the fields that need to be updated, providing more flexible control over update operations.
