Hi Every One,
I have a doubt about session.get() method.we have different overloaded methods with this name.Like..

public Object get(Class clazz,Serializable id)throws HibernateException

and

public Object get(String entityName,Serializable id)throws HibernateException



In the signature of above methods..
1. what is id ? Is it the Primary key in our table?
2. what is entityName in the second method ?

I have a table Event with columns eventId,eventTitle and eventLead.eventId is primary key.
I tried to retrieve data from table depends on eventId value like below..


This works fine for me.

But when i tried to retrive data depends on eventTitle value like below..


But this time i got an exception like....


Please can anybody tell me,how to write code for retrieving all the records related to a particular eventTitle.

Thank q very much.

Hi Everybody,
Any one please give me suggestions about this..
Thanks,

Yes, it is definitely the entity's primary key that is needed.

Here's a little tutorial on Hibernate's load and get methods that you might really find useful.

Thanks Cameron Mckenzie, that tutorial is very helpful.

But i still have one doubt.. How to get a record from a table depends on non primary key.
I posted the situation(getting record depends on non primary key) of my application in my first post.

Can any body please tell me how to solve this problem.I am really stuck with problem.

Any suggestion would be helpful to me..

Thanks,
sirisha.

When you say non-primary key, do you mean you are searching on a non-unique field? You can always use HQL or a criteria query. More tutorials on these subjects can be found through my signature links.
