Hi to everyone. Why does hibernate ovverides my Ids?

I have written some junit tests and in @BeforeEach method I insert entity with specified Ids

But hibernate inserts with its own ids

Store the values as objects (String, Integer, etc – i.e. non-primitives).
And, loop through them & store them in respective arrays (int array, string array, etc) by checking whether it’s an instance of that particular datatype (using instanceOf()).

Better still, create a class with 2 fields: 1. value 2. it’s datatype. And, create an array of objects of the above class. Then you can store them in respective arrays based on the datatype field.

probably your jdk and jre versions mismatch. If you haven’t configured a jdk/jre exclusively in pom.xml, check the buildpath.

I have a table containing ids of second table. How can delete all rows of second table containing ids in table1

I mean, table 1 is just keeping primary keys of second table for delete

I want to write a query to delete all rows from table 2 that have id in table 1

delete from Preference p (table2)
where exists (select 1 from PreferenceToDelete(table 1) ptd
where p.id = ptd.prefId)

This query works but i dont like perfomance

I know there is a solution with inner join
