![]() You have large and complex data models with many optional fields.When to Use Dynamic Insert and Updateĭynamic insert and update operations are suitable when: Note: In above SQL output, you will notice that during the insert operation, all the fields are considered in SQL INSERT query since is not used in this paritcular example. Hibernate: insert into users(country,email,marital_status, name ,id) values (?,?,?,?,?) Hibernate: update users set email = ? where id = ? SQL When performing a normal insert operation using Spring Data JPA, all the fields of the “User” entity, including “id,” “name,” “email,” “country,” and “maritalStatus,” will be inserted into the corresponding columns of the “users” table. Under the default behavior, when persisting a new User instance or updating an existing one, Hibernate generates SQL statements that set all columns of the “User” table. Hibernate optimizes performance by generating a single SQL UPDATE and INSERT statement for each entity class at application startup and reusing them for all insert and update operations. ![]() This behavior may lead to unnecessary database operations and inefficient use of system resources. Similarly, when updating an entity, all fields are updated, even if only a few of them have changed. In the default behavior of Spring Data JPA, when you save an entity, all of its fields are inserted into the database table, regardless of whether they have values or not.
