Question

Basically I’m querying a table like the following

keywordId | keyword

1             abc 
1             abcd 
2             feg 
2             xyz 
2             tuv

When I pass a query such as:

"FROM keyword Where keywordId = 2"

I get back the following:

2             feg
2             feg
2             feg

Here’s the method I’m using

public List<DataModel> selectRecord(String sqlQuery) {  

    SessionFactory factory = new Configuration().configure().buildSessionFactory();
    Session session = factory.openSession();
    session.beginTransaction(); 
    Query query = session.createQuery(sqlQuery);
    List<DataModel> data = query.list();

     session.clear();
     session.close();
     return data;

}

Honestly not too sure why this is happening, but it’s also occuring in other tables with the same structure may FK’s

Insight appreciated! 🙂

Answer 1

Main reason for this is that their is no identifier property in your database. Hibernate is not capable of understanding and that

2 > feg

is different from the below one.

2 > xyz

Best practice would be to define a primary key for the table. You can find more about this issue by visiting this link.Hope this helps
