Abe White commented on OPENJPA-94: ---------------------------------- Note that the "SynchronizeMappings" property allows you to use all the arguments of the mappingtool. So you can try something like: buildSchema(SchemaAction=refresh, DropTables=true) Theoretically, that will drop unused columns and tables while adding any new columns and tables needed for your mappings. > Allow MappingTool and persistence.xml to support drop-create for database > schema > -------------------------------------------------------------------------------- > > Key: OPENJPA-94 > URL: http://issues.apache.org/jira/browse/OPENJPA-94 > Project: OpenJPA > Issue Type: New Feature > Reporter: Shay Banon > > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
