The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Hibernate Criteria for query based on "foreign key"

dear experts,

in hibernate there is great example here http://www.hibernate.org/hib_docs/reference/en/html/querycriteria.html
where we can query a recordset based on certain criterias within the table itself

my question is how if the criteria is on other tabel. Example in "Employee" table that has a foreign key called "address_id" that linked to "Address" table.

Assumed that this "address_id" is mapped as a property named = "theaddress" at hibernate mapping file.  And i want to get a result set where address_id is equal to certain address id.

Anyone can give me example? I tried to use Criterion but still not sure how to get it.

Thanks!

Hi isuhendro,

I have been struggling for the same problem for a while and I managed to find a solution.

The trick I found is to define an Alias as the following snipped. The class such as Employee and Address are indicated with the capital letter, while the table in the DB are prefixed with "tb" to avoid confusion.

This example is using hibernateTemplate with Spring integration, but the concept remains the same...
Enable the SQL logging in log4j to see if the query passed is correct.  Let me know if you have any problem.

hibernateTemplate = getHibernateTemplate();
int myAddrID = 1; // the address ID you want to find
DetachedCriteria criteria = DetachedCriteria
              .forClass(Employee.class)  // the JAVA class for the Employee table
              .createAlias("tb_address", "addr")  // the table name
              .add(Restrictions.eq("addr.id", myAddrID));
return (List<Employee>) hibernateTemplate.findByCriteria(criteria); // The list of the Employee that have the address_id property as wanted
Open in New Window
Accepted Solution
