If the "LIKE ... ESCAPE" clause is defined in a Hibernate filter, for example:

@Entity
@FilterDef(name="ignoreSome", parameters=

)
@Filter(name="ignoreSome", condition="address like :youraddress escape '\'")
public class Member implements Serializable {

when the filter is enabled, the following errors are thrown:

Caused by: org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "SELECT THIS_.ID AS ID1_0_0_, THIS_.ADDRESS AS ADDRESS2_0_0_, THIS_.EMAIL AS EMAIL3_0_0_, THIS_.NAME AS NAME4_0_0_, THIS_.PHONE_NUMBER AS PHONE5_0_0_, THIS_.STARTDATE AS STARTDAT6_0_0_ FROM MEMBERHIBERNATE4DEMO THIS_ WHERE THIS_.ADDRESS LIKE ? THIS_[*].ESCAPE '' ORDER BY THIS_.NAME ASC "; SQL statement:

Please note that the key word "escape" is interpreted as a column name:
where this_.address like ? this_.escape ''

I've run a similar query using the Query object, everything works fine.
For example:
Query query = em.createQuery("from Member where address like :youraddress escape '\'");
query.setParameter("youraddress", "Brno%");

The "LIKE ... ESCAPE" query is supported in JPA based on the spec. So, is this a Hibernate bug or something that's not supported in Hibernate Filter?

I'm attaching a simple reproducer here for your reference.

Please take particular look at org.jboss.as.quickstart.hibernate4.model.Member and
org.jboss.as.quickstart.hibernate4.data.MemberRepository (findAllOrderedByAddressFilter)
