It has since 3.0. It's already in beta (and RC1 will likely be this year),
so I advice you to switch.
Otherwise, try
Expression exp = new ASTBetween(new ASTDbPath(pathSpec), value1, value2);
(not sure this is complatible with 2.0)

but the ExpressionFactory doesnt have betweenDbExp.
I'm using version 2 btw

Hi,
I guess this produces the 'IN' operator.
This would mean I need to produce all the key values in the range I want
to
retrieve?
Is there not a betweenDbExp?

Hi,
Some paginated mechanisms are based on a persistence layer to be able
to
retrieve records for a range of primary keys.
I know it is possible to insert the primary key field in the definition
but
then I'm also required to populate it
when I create a record. I'm using a sequence generator to determine the
key
value of a new record.
So my question is: without having to insert the key field in the
definition, is it possible to query the table
by primary key range, and if yes, how?
