How to Limit Query Results in Hibernate 3 (without using LIMIT)?

Limit Queries in JPQL or HQL

In Hibernate 3, the equivalent of the MySQL LIMIT clause in HQL is not directly available. Attempts to use it in HQL will result in an error, as LIMIT is not a supported clause.

Originally, this functionality was unintentionally available in Hibernate 2 due to a quirk in the HQL parser. It replaced recognized HQL elements while leaving unrecognized portions alone, allowing users to sneak in native SQL statements.

However, in Hibernate 3, the HQL parser has been significantly enhanced and utilizes an AST (abstract syntax tree). This strict parsing implementation explicitly disallows unsupported clauses such as LIMIT.

Therefore, the recommended approach to limit query results in Hibernate 3 is to use the setMaxResults() method on the Query object. This option provides control over the maximum number of results returned by the query, effectively achieving the same functionality as the LIMIT clause.
