If we patch SemanticQueryBuilder. visitIsNullPredicate to push allow multiple value bindings on the stack, everything works as expected and documented, that is it we do: @Override public SqmNullnessPredicate visitIsNullPredicate(HqlParser.IsNullPredicateContext ctx) { parameterDeclarationContextStack.push( () -> true ); // allow multiple values for null checks try { final boolean negated = ctx.getChildCount() == 4; return new SqmNullnessPredicate( (SqmExpression<?>) ctx.getChild( 0 ).accept( this ), negated, creationContext.getNodeBuilder() ); } finally { parameterDeclarationContextStack.pop(); } } ( https://hibernate.atlassian.net/browse/HHH-16268#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16268#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
