select distinct field (with OJB)
Hi all,
Can anybody tell me in a few words how to execute the following SQL
(Oracle) instruction with OJB:
SELECT DISTINCT fieldname FROM tablename
I allready tried it with QueryBySQL QueryByCriteria and
ReportQueryByCriteria but it never worked.
Thank you in advance.

Hi Jakob,
I did not understand your answer.
What has the addLike method in the Criteria to do with a distinct query?

hi marco,
it's a flag in the query.
Criteria crit = new Criteria();
crit.addLike("allArticlesInGroup.articleName", "C%");
// distinct
QueryByCriteria q = QueryFactory.newQuery(ProductGroup.class, crit,
true);
