Re: [perfectjpattern-users] Queries in Jpa dao

[Giovanni A. <bra...@gm...>]

Hello again,

Oh I see now what you mean.

I am sorry in 1.0.2 there is no way to do that, IQuery is quite limited. If you could fetch and build the snapshot 1.0.3 (trunk) then you can do this is the way you want. In 1.0.3 all improvements related to the Generic DAO implementation (including adding the necessary IQuery features) are stable and fully covered with unit tests.

Best regards,
Giovanni
