Hiberante Native Query, column not found

I am trying to print the SQL query result but says column not found,

public class SearchDriver {

    @Autowired
    EntityManager entityManager;

    public void  search(String key, String value){
List<Driver> resultDerivers = entityManager.createNativeQuery("select * from driver where "+key+"="+value).getResultList();

       System.out.println(resultDerivers);

//end of method 

}

The String values in sql query must be enclosed by quotes so in your case, your code should check if the value is a string and in this case add ' before and after the add the value to the query. Or to make it cleaner make to different methods one for numerical values and one for String and call one or other depending on the data that you want to use as filter:

    public void  search(String key, Int value){
    List<Driver> resultDerivers = entityManager.createNativeQuery("select * from driver where "+key+"="+value).getResultList();
}

    public void  search(String key, String value){
    List<Driver> resultDerivers = entityManager.createNativeQuery("select * from driver where "+key+"='"+value+"'").getResultList();
}
