Database Query using Hibernate

Hi,
We are working on a migration project. Currently we are using stored procedures for fetching the data which uses linked servers to fetch cross server data. Below is a query to give you some idea.



Please suggest the best way to implement this using Hibernate. Thanks in advance for any suggestion.

Hi and welcome to the JavaRanch.

Since you haven't put in a lot of effort in your post I'm not expecting that people are going to help you out a lot. You could start by telling us what you have done so far or what you're planning to do and why. Then we could give you suggestions about how to implement it in another/better way.

Currently we have 2 databases on our system where we are using linked servers (SQL SERVER) to fetch the data from both the servers (Cross database query).

In future we would like to move our Database from SQL Server to MySQL and thus we does not won't to use native sql or stored procedures as it will add extra efforts for the database migration project.

Now I am trying to implement hibernate using POJOs but my cfg files are pointing to 2 different servers. How can I achieve connectivity between 2 different databases or querying between 2 different database tables.

Please suggest how to achieve or suggest a better way of doing it.

Thanks,
Rahul

Did you try using NHibernate?
It works well with multiple databases
