Hi all,
I use JBoss 4.2.0 + jBPM 3.2.1 + Hibernate 3 with a PostgreSQL 8.2.4 database.
I'd like to perform an HQL query which could generate the following SQL query :
select name_, version_
from jbpm_processdefinition d1
where not exists (select name_, version_
from jbpm_processdefinition d2
where d2.name_ = d1.name_
and d2.version_ = d1.version_ +1)
Is there a way to do that ?
select d1.name, d1.version
from ProcessDefinition d1
where not exist (select d2.name, d2.version
from ProcessDefinition d2
where d2.name = d1.name
and d2.version = d1.version+1)
doesn't work.
Regards
A. ROY
