Question

I have a queryString along the lines of:

session.createSQLQuery("SELECT C.FIRSTNAME AS firstName, C.LASTNAME as lastName FROM ADDRESSBOOK_CONTACT AS C WHERE C.ADDRESSBOOK_ID = :addressbookId AND firstName = ?");

When setting my positional parameter, the query is run as normal but there is no result:

query.setParameter(0, "firstname1010");
query.setParameter("addressbookId", addressbook.getId());

Which is wrong. If I change my positional to named:

query.setParameter(firstname, "firstname1010");

Then my query returns the correct results.

Without going into a convoluted explanation as to why I am doing this, I would like to know if mixing the two types should be supported or not? I am using hibernate 3.6.3.Final

Answer 1

From the Class level docs on org.hibernate.Query:

You may not mix and match JDBC-style parameters and named parameters
in the same query.

So the behaviour you’re seeing is completely expected.
