There are several methods available in Hibernate for performing bulk updates of data.<\/p>\n

    \n
  1. Perform bulk updates using HQL statements.<\/li>\n
  2. Execute an update on the Entity object, setting the property to a new value where the condition matches a specific value.<\/li>\n
  3. In this context, the “Entity” refers to the name of the class to be updated, “property” is the name of the attribute to be updated, “value” is the new attribute value, and “condition” is the updating condition. The update operation is performed using the query.executeUpdate() method, which returns the number of rows affected.<\/li>\n
  4. Performing bulk updates using Criteria API.<\/li>\n
  5. Using CriteriaBuilder, create a CriteriaUpdate object for the Entity class. Set the root entity and update a specific property with a new value. Set a condition on the root entity and execute the update query with the session.<\/li>\n
  6. In English, the “Entity” here refers to the class name that needs to be updated, “property” is the name of the property to be updated, “newValue” is the new value of the property, and “condition” is the update condition. The update operation is executed using session.createQuery(update).executeUpdate() method, which returns the number of rows affected.<\/li>\n
  7. Use batch update SQL statements:<\/li>\n
  8. The code above updates a property in the entity table based on a condition using the provided values.<\/li>\n
  9. The “entity_table” here is the name of the database table to be updated, “property” is the name of the property to be updated, “value” is the new property value, and “condition” is the update condition. Execute the update operation using query.executeUpdate() method, which returns the number of rows affected.<\/li>\n<\/ol>\n
