Subject [jira] Commented: (OPENJPA-94) Allow MappingTool and persistence.xml to support drop-create for database schema

Sherry Shen commented on OPENJPA-94:
------------------------------------

With openjpa-0.9.7-incubating-SNAPSHOT on 2/26/2007 nightly,  I have tried followings:
A.  <property name="openjpa.jdbc.SynchronizeMappings"
              value="buildSchema(SchemaAction=add,SchemaAction=deleteTableContents)"/>
My test works without previous test data in rerun. 
This ensure that I have a clean test data in each run.

B.  <property name="openjpa.jdbc.SynchronizeMappings"
               value="buildSchema(SchemaAction=drop,SchemaAction=add)"/>
My test runs, but with previous test data in rerun. 
What action drop does?

> Currently, in the persistence context, one can define:
> <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema" />
> Which causes OpenJPA to build the database schema based on the mapping defined. Currently,
there is no way to define it to drop tables if they exists before creating the database schema.
This is very useful for tests that drop (if exists) and creates new tables for each test.
