Hibernate encountered an error in executing hql statement

this is to get List < PortfolioMemberView > at the Dao layer, and I am in the

public List<PortfolioMemberView> getPortfolioMemberViewByPid(Integer pid){
        //portfolioId 
        System.out.print(pid);
        try {
            Session session = sessionFactory.getCurrentSession();
            String sql = "from PortfolioMemberView pv where pv.portfolioId = ?0";
            Query query = session.createQuery(sql).setParameter(0, pid);
            List<PortfolioMemberView> pmvl = query.list();
            //printconsole
            for(PortfolioMemberView pv: pmvl){
                System.out.print(pv.getAssetCode());
            }
            return pmvl;
        }catch(Exception e){
            logger.info(":"  + e.getMessage() + ", " +e.getCause());
            throw new RuntimeException();
        }
        
}

at this point I have the following data in the PortfolioMemberView view of the database,

the output from console to me when the method is triggered is like this,

Hibernate: select portfoliom0_.portfolioId as portfoli1_8_, portfoliom0_.assetId as assetId2_8_, portfoliom0_.accountType as accountT3_8_, portfoliom0_.assetCode as assetCod4_8_, portfoliom0_.assetLabel as assetLab5_8_, portfoliom0_.value_ as value_6_8_, portfoliom0_.annualReturn as annualRe7_8_, portfoliom0_.returnRate as returnRa8_8_ from PortfolioMemberView portfoliom0_ where portfoliom0_.portfolioId=?
CMPROP0121CMPROP0121CMPROP0121CMPROP0121CMPROP0121

I don"t quite understand that when portfolioId is 2, the asseCode attribute of the corresponding three records should be CMPROP0121,kckb,GYck,
, but the result is missing three CMPROP0121 in a row. I can"t see where this bug is caused. Hibernate printed the generated sql statement in console. I ran to the database and the output was correct. However, the list results obtained by this method are not correct.
ask God for help.

did you turn portfolioId map into id? This is the caching mechanism of hibernate. It takes the first row and caches it according to id. When taking the second row, if the id is the same, hibernate will think they are the same, and will directly extract the output from the cache.

if there are duplicates in portfolioId, do not map into id.
