Subject: [Andromda-user] HQL, uniqueResult & named parameters

  Hello !

  I continue to did into AndroMDA and more and more questions are coming 
up ... For the moment, I'm playing with the query generation, using HQL. OCL

would probably be better, but I dont know anything about it, and I didnt see

where to enter it in AndroMDA Community Edition ... we'll see later.

  About HQL :
  Is it possible to generate a query that returns not a list, but a single 
instance (The equivalent of query.uniqueResult() in Hibernate) ?

[CB] Are you using the Spring cartridge?  If you are using Spring you can
return a single element from your query in your model (if you're using the
hibernate cartridge without spring you can't currently do this, although
this should be fixed)....so if you want to file a JIRA issue for the
Hibernate cartridge that would be great.

  Second question : is it possible to generate queries that use named 
parameters ? It's more a cosmetic issue than anything else, but ...

[CB] Yes, you can set this namespace property
"hibernateQueryUseNamedParameters" to true (for either the Spring or
Hibernate cartridge).

 Again, thanks for the great software and the great help !
