Spring Boot | Dynamic Inserts & Updates With Spring Data JPA | JavaTechie

In this tutorial, we will learn how to use @DynamicInsert & @DynamicUpdate annotation in spring data JPA and their purpose of using in real time app
@DynamicInsert annotation ensures that Hibernate uses only the given columns in the SQL statement that it generates for the create of an entity.
@DynamicUpdate annotation ensures that Hibernate uses only the modified columns in the SQL statement that it generates for the update of an entity.

Thank you as always, this is really great, and a very powerful yet simple way for performance improvement. Is there any downside to it as I wonder why it is not included by default?

[@Javatechie]

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

[@AnkitPandey-tl9vu]

good stuff ! but If you're updating or inserting a large number of entities, the extra overhead of generating dynamic SQL statements at runtime could impact performance right ?

[@Javatechie]

Yes that's correct

Good morning Basant, can these two annotations(@DynamicInsert and @DynamicUpdate) replace PATCH HTTP Method?

[@Javatechie]

No these annotations will just optimise the query

[@PixelLoafLatte]

Thank you, i think this is impossible with jpa, so i do native query all the time lol. How about dynamic select and join? jpa always select more fields than i need

[@Javatechie]

For select and join will check and update you

[@vengateshm2122]

For dynamic update you gave name and price in request body in post man but query showed only price column. Is it because the new name and existing name are same?

[@Javatechie]

Yes correct. @DynamicUpdate is smart enough to scan it .

[@Tout-Le-Monde02]

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 ......

[@Javatechie]

If you won't pass those values then null will be updated in DB

[@Tout-Le-Monde02]

@@Javatechie No it doesn't.

Everything is ok but 100 columns in table is too bad design to have. Ideally should not be referred to as an example.

[@Javatechie]

Just an example buddy 😊. We can keep more than 15 columns right 👍

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

[@matusseidl]

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

[@Javatechie]

How buddy?

[@matusseidl]

@@Javatechie Hibernate does not use the cached SQL statement for Dynamic Update or Insert which means every statement is generated and not pulled from the cache

[@Javatechie]

@@matusseidl yes if hibernate will use cached SQL statement then in single value update will trigger update for all the attribute/columns present in your entity right? This will eat a lot of time as well as memory

[@matusseidl]

​ @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.
