    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3788?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33101#action_33101 ] 

Rafael Santini commented on HHH-3788:
-------------------------------------

Diego,

I have extended the FirebirdDialect to workaround this problem:

Class:

package br.com.biblioshop.framework.hibernate.dialect;

import org.hibernate.Hibernate;
import org.hibernate.dialect.function.NoArgSQLFunction;

public class FirebirdDialect extends org.hibernate.dialect.FirebirdDialect {

    public FirebirdDialect() {
        super();
        registerFunction("current_date", new NoArgSQLFunction("current_date", Hibernate.DATE, false));
    }

}

Configuration:

<prop key="hibernate.dialect">br.com.biblioshop.framework.hibernate.dialect.FirebirdDialect</prop>

> The FirebirdDialect does not supports current_date() function. A select like "select * from test where dt < current_date()" causes the following exception:
