Hello Brian Payton,
Thank you for your answer. I’ll take
a look at the SQLQueryParserInteractiveTest first.
Basically, I want to create a SQL Query
model based on a given query text and then manipulate that model. For example,
given a query text like “SELECT * FROM t1 WHERE a1 = 5;”, I need
build a model to represent this query and modify each clause in this query (e.g.
add/delete/modify the predicates in WHERE clause), then output the changed
query text.
Thanks and Best Regards!

query model in ModelBase
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

SQL query model in ModelBase
Sent by: dtp-models-dev-bounces@xxxxxxxxxxx
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!
