Hibernate Query Language (HQL) is extensive. Nearly every SQL query can be done with HQL in an object oriented and briefer manner. Creating queries, whether SQL or HQL queries, is a complex task. Programmers generally design an initial structure and evolve the query until expected outcome is obtained. For this purpose, tools for interacting with relational databases with query languages are developed.
A query tool’s main purpose is to provide user with an interface where s/he can discover data structure, enter queries against this structure and data contained and see the results.
Current HQL Tools have some drawbacks. Some of them is not in sync with latest Hibernate versions, some of them locks users into an arbitrary development environment, some of them lacks essential features like a decent HQL syntax analyzer and word completion.
The purpose of this work is to develop an HQL query tool that has most of the essential features of previous ones, without having the drawbacks. The features incorporated include Hibernate session factory configuration, results browsing, advanced query editor and query debugging.
Future improvement can be focused on providing a smarter and more powerful query editor, mapped objects visualization and usability.
