Java Hibernate org.hibernate.exception.SQLGrammarException: could not extract ResultSet on createSQLQuery

I have this method.

private final void updateAllTableFields(final Class clazz){
final String tableName = ((Table)clazz.getAnnotation(Table.class)).name();
final String sqlQuery = new StringBuilder("SET @ids = NULL; ")
.append("UPDATE ")
.append(tableName)
.append(' ')
.append("set activeRecord=:activeRecord ")
.append("where activeRecord=true and updateable=true ")
.append("and (SELECT @ids \\:= CONCAT_WS(',', id, @ids)); ")
.append("select @ids;")
.toString();
final Query query = session.createSQLQuery(sqlQuery)
.setParameter("activeRecord",Boolean.FALSE);
final Object idsList=query.uniqueResult();
System.out.println("idsList = " + idsList);
}

I want to do a update and also return the affected Ids this works Perfect using a rawSQL returns the id in a string fashion but i couldn’t make it work using Hibernate any tip!!!

Thanks in advance and best regards.
