[jboss-dev-forums] [Design of JBoss jBPM] - Re: [sim] problems with hibernate queries and dates

[tom.baeyens@jboss.com]

portability wins against speed if you need to make the tradeoff.

indeed, a db compatibility layer could handle that.  try to look into how people can customize the queries.  can they customize the queries in the simulation queries hbm file ?  meaning; is the API that we have to use to execute those queries the same for HQL as for native SQL queries ?

if we can work out a solution like that, we can provide portable configuration file with HQL queries (perhaps slow, but portable)

then people should be able to configure for their database a faster native SQL.  but then their on their own.  we could devote a wiki page where people could exchange their experiences.

but i expect that the hibernate API will not be exactly the same.  so that needs to be figured out.
