Re: [dtp-models-dev] SQL query model in ModelBase

[Brian Payton <bpayton@xxxxxxxxxx>]

Hello Alex,

The SQL  model and SQL Query model
are both based on EMF, so they provide a comprehensive API that can be
used from both UI-driven and non-UI-driven applications.

If you are creating a SQL Query model
incrementally, then take a look at the "xxxHelper" classes in
both the org.eclipse.datatools.modelbase.sql.query plugin and in the org.eclipse.datatools.sqltools.sqlbuilder
plugin ("model" package). 

If you are creating a SQL Query model
by parser SQL source, then take a look at the SQLQueryParserInteractiveTest
class in the test plugin org.eclipse.datatools.sqltools.parsers.sql.query.test.
 The test plugin is available the DTP CVS repository:

  Host:  dev.eclipse.org 
  Repository path:  /cvsroot/datatools 
  Module: org.eclipse.datatools.sqltools/plugins/org.eclipse.datatools.sqltools.parsers.sql.query.test
  Connection type: pserver 
  User: anonymous

SQL query model in ModelBase

Hi all, 
I am writing to consult one tihing about the model base project in DTP.
Does ModelBase (or other module) provide public APIs for a non-UI driven
application to build a SQL query model?

My expected behavior is:
1) build a specified SQL query model
2) manipulate the model
3) transform the model to a SQL text string.

Does ModelBase support this?

Thanks and Best Regards!
