Hi all,

I have a basically simple question, which seems to be hard to track down. I tried to search but actually I'm not even sure what I search ;)

What I've done: So far I installed Hibernate, created the config and the mappings and did some first testing (inserting data). This all worked very well. Now I wanted to load some data and got stuck.

I have a class called "Person" with variables like name, surname, city etc. I now want to present a search form to the user in which he can fill in the name and/or surname and/or city to search.

What would work is to create a Query string based on the input with "if" clauses. But somehow I think there has to be a better way. What I would love to do is to create an instance of the Person class, then fill in the variables I have (based on the UI) and then call a single method do load the data, based on the variables of the instance.

In an ERP System I use I can do that with "select choose", but I didn't find something similar in HQL. I also tried a criteria, which basically worked. But when I tried to not enter all data, it got no result.

I looked into criterias, filters and collections, but got confused. Maybe if only someone could point me into the right directions (e.g. "use collections!"), I might find the solution faster...

thanks in advance

Use Example queries!

Wow, thanks a lot. I knew there has to be a simple way, but I felt like searching for trees in a forest ;)

It worked like a charm... ;)
