Hi, After digging further, it seems to me that there is a bug with Hibernate 5.3.
I debug and step through the query handling, and the generated QueryDSL query seems correct to me: ========================= select queuedTaskHolder from QueuedTaskHolder queuedTaskHolder where queuedTaskHolder.status in (?1) and queuedTaskHolder.queueId = ?2 order by queuedTaskHolder.id asc ========================= The (:x1_0, :x1_1, :x1_2, :x1_3) part appears in the hibernate query handling inside layers, in org.hibernate.query.internal.QueryParameterBindingsImpl.expandListValuedParameters(String, SharedSessionContractImplementor) method. It seems that the purpose of this method is to transform query and parameters arguments when argument is a list. So query is rewritten with named parameters, and query parameters are modified to inject this new parameters. And this query is then rejected in org.hibernate.hql.internal.ast.HqlSqlWalker.generatePositionalParameter(AST, AST) because there are namedParameters. If I switch dependency to 5.2.12.Final release, the same code works. I'll try to write a minimal test-case about this when I'll get some spare time. -- Laurent Almeras On 02/02/2018 06:00 PM, Laurent Almeras wrote: > Hi, > > Testing Hibernate 9.3.0.Beta2, I run into this issue: > > > =============== > Cannot define positional and named parameterSpecs : select > queuedTaskHolder > from org.iglooproject.jpa.more.business.task.model.QueuedTaskHolder > queuedTaskHolder > where queuedTaskHolder.status in (:x1_0, :x1_1, :x1_2, :x1_3) and > queuedTaskHolder.queueId = ?2 > =============== > > > Hibernate complains that query contains both named and positional > parameters (note that this query use to work on Hibernate 5.2.x). > > This new behavior is linked to: > > * this commit: > https://github.com/hibernate/hibernate-orm/commit/5e0274adbbd3e0aa3092c29a765fd203c8279126 > > > * this issue: https://hibernate.atlassian.net/browse/HHH-12116 > * and this parent issue: https://hibernate.atlassian.net/browse/HHH-12101 > > I also find that you already talk about this behavior on this same > mailing-list: > http://lists.jboss.org/pipermail/hibernate-dev/2016-September/015460.html > > > I think that allowing this behavior was not a good idea, so I don't have > any hope that you consider this as a bug.
