Re: [OJB-developers] [ann] new release

[Jakob B. <jbr...@ho...>]

hi,

i have a problem using OQL.
when i try to run the following qurty with a between criteria

query.create("select persons from brj.ojb.Person where test between $1 and
$2 and name like $3");
query.bind(new Integer(80));
query.bind(new Integer(100));
query.bind("%er");

i get the following error:

org.odmg.QueryParameterCountInvalidException
at ojb.odmg.oql.OQLQueryImpl.bind(OQLQueryImpl.java:122)
at brj.ojb.TestODMG.queryBetween(TestODMG.java:67)
at brj.ojb.TestODMG.run(TestODMG.java:88)
at brj.ojb.TestODMG.main(TestODMG.java:26)

the problem comes imho from OQLQueryImpl.bind(Oject parameter)
...
SelectionCriteria crit = (SelectionCriteria) this.bindIterator.next();
crit.bind(parameter);
...

when binding a between criteria the bindIterator should not be advanced
after the first parameter.
