How to use regular expressions with Hibernate/Oracle

Question

I\'m trying to implement a web service which accepts a list of strings, each of which is a regular expression. These need to be compared against six columns of a database,

Answer 1

Similar working example

 Criterion criterion = Restrictions.sqlRestriction("regexp_like (column_name, ?, 'i')", "(^|\\s)"+searchValue+"($|\\s|.$)", StringType.INSTANCE);

Answer 2

There's nothing in the hibernate docs for performing regular expression queries (using HQL or Criteria queries). The approach using the sqlRestrictions should probably be changed to one of the overloaded methods to avoid a SQL Injection vulnerability.

Example code:

Restrictions.sqlRestriction("regexp_like({alias}.NODE_1, ?)", re, Hibernate.STRING)
