Hello,
is it possible to use the SQL statement model in the modelbase
standalone? We are searching for a lib that gives the programmer an easy
API to create complex SQL statements without actualy writing SQL code.
Additionally it would be fantastic if the lib knows about the db schema
and could validate the SQL statement during creation.
Could we use some of the DTP parts for that approach? Do someone know an
alternative?
Regards, Kai

Hi Kai,
If by "standalone" you mean still in Eclipse with EMF but not the rest of
DTP (connectivity, SQL Dev), then the answer is "yes." The SQL model
consumes a JDBC connection, so, as long as you can provide that, you can
use the model. A SQL model instance for a given JDBC connection knows
about the meta-data, and the SQL Query model uses the SQL model. While
there is no automatic validation like you describe above, all of the
necessary pieces should be there to do so.

Hey Graham,
thanks very much for your answer.

I mean standalone with all necessary dependencies like EMF but maybe not
in an Eclipse env.

Okay that sounds good. Could you give me a short code example how to use
the model with a JDBC connection? I read the UML docs and the reference
but it seems I didn't hit the right pages.
THX is advance.

Hi Kai,
If by "standalone" you mean still in Eclipse with EMF but not the rest of
DTP (connectivity, SQL Dev), then the answer is "yes." The SQL model
consumes a JDBC connection, so, as long as you can provide that, you can
use the model. A SQL model instance for a given JDBC connection knows
