Hibernate query gives same record multiple times

Question

I am working on hibernate in eclipse. I am executing simple \'From\' query. Here is the code

  List list = sess1.createQuery(\"From Myview\").list();
    System.         


        

Answer 1

You should use the distinct keyword to filter the same result.

Answer 2

If you have association in the mapping then check if fetch=FetchType.EAGER. If yes then use other fetch type or fetchMode.

Answer 3

Put the objects returned by Hibernate to a LinkedHashSet and return the LinkedHashSet.

Answer 4

This happens when the id element in your hbm file is not a PK in your DB table. Hibernate treats all rows with the same ID as the same object.

Either change your id element to point to a PK column or use the composite-id element in case your table only has a composite primary key.

Answer 5

Your entity Myview have to implement java.io.Serializable interface

Answer 6

Are you sure that the table is correctly filled? try :

List list = sess1.createQuery("SELECT * FROM Myview").list();

futhermore, you are getting this list from a view? are you sure that you made this view correctly?
