Hello, I am using spring data jpa and hibernate 6.2 to interact with my tables and I have a specific case which I cannot solve.
I am using a native query to select records and I would like in that native query to also include a calculated column. Only that select query has this addition. In any other case and actions I would like to ignore it.
What I have tried to far:
I extended the query with my calculated value (I’m using spring repository and the
@Query annotation for that) and I added a new field in my @Entity class.
This immediately creates problems since when I try to insert this new field in the class, is not mapped to a real column, only my custom native query uses it. I added the
@Column(insertable = false, updatable = false) annotation but when I do a deleteAll() again it fails as this field doesn’t exist in the select (hibernate performs a select and then deletes the records.)
I tried the
@Formula and again selects fail since that field is not mapped to a column.
I tried the
@SqlResultSetMapping as described here but in my case I am using spring and not running queries the “manual” way.
At the end my final solution I think is to create another entity same as the old with this additional field and only use this single native query.
