Spring is completely irrelevant to your question. Its all about the MySQL database and the way you have defined the tables in your DDL.

You cannot delete a Parent row if a Child row exists on your database because of how you defined that constraint.

There is a ON DELETE .... syntax which tells MySQL what to do when a parent row is deleted, by default MySQL will reject the delete, you can change this in a number of ways, as specified in the MySQL manual, of all the odd places.

In your case as you want to NOT DELETE the Employee when you delete the Department, and you have the column

You have to change the value of field allOrgMstOrganizationId from empty object to null. Maybe this will solve your problem. The dataset be like bellow:

The first step would be to look at where/what this TRP_ConDetail is mapped to, because nothing in that name correlates with an UPCHKD table. Since there are no attributes in the entity class other than [Key], the two places to check will be in the DbContext itself (hrmsEntity) for the OnModelCreating() method, or looking for a class in the solution of type EntityTypeConfiguration which would indicate which Table or View in the database this entity is mapped to. This would also reveal any properties pointing to the "Earned" column that have been renamed for the class.

Given you mention his code is only pulling "D03" values, my hunch would be that the TRP_ConDetail is a view because there is no filtering code logic going on in that code you pasted. That code is mapping an entity to either a table or a view and outputting the entire set. There may be a view in the database called TRP_ConDetail where you would find something like WHERE UPCHKD.EARNED = 'D03' which you would extend to include you "D03B" value.

HOWEVER, keep in mind if that is how the system was implemented, it is a warning that this would be a very bad design as if you make that change it will impact everywhere that this TRP_ConDetail DbSet is referenced. Any other code that was expecting only D03 would now receive both D03 and D03B so this may very well introduce bugs in other areas of the system. Filtering rules in underlying views should be avoided unless it is very core-level globally applied rules for exactly this reason. Normally what you would expect to see is filtering done in the Linq expression:

For example if the view simply combined this UPCHKD and maybe some related data where a field like "Earned" was part of the view, then the Linq query in that area of the code would have looked more like:

Actually I have mentioned firebase project name in audience in mongodb but we need to mentioned firebase projectId instead of project name. It's working fine. If you have any other queries check in this link Custom JWT Authentication

Perhaps you could not declare addJob method in JPARepository Please read about the

4.2 Query Methods https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.query-methods

You will get a tons of sample if you search Spring JPA CRUD sample

I solved this problem. I added to users table this anotation from javax.persistence.

You can not get link, cause website use AJAX requests to update pages. But you can parse all you needed data. For example I get ID from start page and schedule from details page. You can use next code

Mapping the result of a query with a DTO using the new keyword in a query only works for JPQL, it will not work for SQL (which is what you are using).

It also looks to me if you are trying to write a too complex query as everything can be achieved/reached through the JobPosting class, which will implicitly do the join when using JPQL.

So instead of your native SQL writing a JPQL should fix it.

Something like
