Hi, what if I must insert data before start the app. for example, using Flyway, how to prevent a Id value collision?

Very well explanation, could you please provide the link for Guide to JPQL Query?

Good Morning, I have a scenario to fetch the data from teradata sql views by using spring-boot-data-jpa with no primary key column in database. 1. When using entity it is expecting primary key but we don't have the PK ID column in database. Existing behaviour of data mapping: They joined multiple views and getting the data and mapping DTO class by using RowMapper with spring-boot < 3.x Expected: After >3.x spring-boot version upgrade data binding is not happening. If you have any idea that would be great helpful to me?? Thanks Note:I have done the all the code change related to JPA but getting the Exception like ID column not found in database because as mentioned don't have Id column in views..

Thank you Thorben. 👍

Good work, thanks

tell me when query gives you list of names then how to get that list?

WHAT ABOUT INSERTS ?

Coole Beispiele. 👍

How to migrate to previous versions?

This video is a pure gold. Thanks sir

Thank you sm for help!

Is there a measurable performance hit for the property-has-changed determination, and, if there is, is that hit offset by less downstream cost (slimmer i/o from the appsrvr to db, and obv. within the db)?

Could you please share link to your source code?

Thanks for the content ! how write jUnit test of class with enum properties. Like public interface HouseRepository extends PagingAndSortingRepository<House,Long> { Page<House> findByHouseTypeContaining(HouseType houseType, Pageable pageable); } @Entity(name = "house") public class House { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "house_sequence") @SequenceGenerator(name = "house_sequence",sequenceName = "house_sequence",allocationSize = 1) private Long id; @Enumerated(STRING) private HouseType houseType;

Nice to hear from you again, Thorben!

Thanks for tip.

You said update method throws an exception but it didnt throw any exception in ur video

Any sample code to generate custom sequence, am using <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>3.2.5</version>

like always very nice video.

Suppose I have Existing Spring project and all db connections everything has been done there in application.properties , Now I want to use flyway for existing proeject in Production , Do we really need baselining for that also ? if yes then why : if no then how ?

Good content. Please could you React in your next video. Thanks

how to implement pagination? I can't find any info

You save me a lot of troubles. Thanks for sharing!

The problem is not huge graph and "complex" joins. You can join many relationships. The real problem is the cartesian product when you join multiple ToMany relationships. In you example, if an author write 10 books and theses books are published, each by 5 publishers, you will have 10×5 rows = 50 in the resultset returned by your DB. If you join 10 ToOne relationships, no problem. So we cannot talk about graphs without talking about cartesian product

There is one problem with this solution. While you are using for loop to remove all books CocurrencyModificationException occures.

I don't know if this is OOP's fault, or hibernate's, but this is ridiculous, overcomplicated bull$hit. All we need is getAndIncrement a sequence from the database, and perform an insert in a transaction. How are we supposed to remember this (which solution doesn't work since hibernate 6)?

Does slow-query-logging create noticeable overhead when queries are not slow and nothing gets logged? It seems useful to have it activated in prod, and when a request is slow because of a truly slow query than I don't care much if it gets a tiny additional slowdown from writing a log-message.

You Always awesome Thorben

what if we have multiple Dto classes and need to map query result to objects of dto

Thanks !!

it's okay to use merge when I want to update child entities?

Unfortunately, this didn't work for me. I have Offer (one-many) Items (many-one) StockInfo (many-one) Product. The last table (Product) doesn't get fetched... Don't know why. I had to use a Query with multiple JOIN FETCH.

1:10 why do you call "private Book book" class variable an "Entity attribute"?

Great content it was very helpful.

on the outbox table slide, what is the use of aggrID where is already have an ID as the primary key? also, in the book service slide you show the outbox table without a aggrID field. is this on purpose?

This is giving the below error : Recognizing native query as a function call is no longer supported

Question: Is there anyway to access Join tables using criteria API ?

3:31 5:52 @Transactional 6:06 propagation enum 6:22 REQUIRED - default 6:54 NOT_SUPPORTED

the only disappointment I have , is I have just found this channel

Please share the source code

I have 2 entities: Table1 : embeddedId -> number, code Table2: embeddedId -> number, code want to left join table2 on table1 using criteriaquery. I am getting error: cannot join basic attibute, tried alomost everything,

There is no complex query

Why does spring try to overtake the industry? I don’t like

This doesn't work, firstly, callable=true already presents an error
