Thanks for giving me an updated one.

Damn I was looking for this last week.. just one annotation helps

Thanks 😊

Thank you. In update operation, When i was using model mapper to convert DTO to DB object, fields like created date time becomes null by default since not present in DTO. For update, i don't need to reinitialize those fields now. Thanks

As i mentioned hibernate load default insert and update query by considering all the attributes of your entity.this way every time hibernate will reuse the same query to increase it's internal performance of using query but it will impact on application performance

14:14 why are you sending all the other fields in your json request body, if you intend to only update the description field? That's why hibernate is generating update script for all the fields ...... and forcibly passing null as a json field value is not at all a good design principle ..... just don't include those fields in the json ...... weird logic ......

This is a bad video because you didn't explain that using the dynamic annotations has a performance cost. In most cases it's better Performance to leave it out, it's only good when your entity has a large amount of fields that are large in length

@DynamicUpdate or @DynamicInsert has a performance overhead associated with it. Don't forget on it

​ @Java Techie maybe, it could be good video compare those scenarios. And yes if you have entity with many fields (columns) 20-30 and you just update one of them and that update isn't executing often I could use DynamicUpdate.
